  • My curiosity is how bright will it be at night? And having a voltage regulator to control the brightness of the led could come in handy for Night time events. LOVED THIS PROJECT

    • Yea would love to see it indoors or in night.

    • @Franz Rupert I was just going to say that some potentiometers shouldn't be too had to install on the outside, and it shouldn't be too difficult to wire in.

    • Fix this on your car and you don't need head lights 😉

    • @Iskander K or just add a light sensor...

  • I wanted to quickly mention, the source of the glass does matter. If using a window, make sure it's not a more modern one, they are now built to block UV, meaning it would be impossible to cure the UV reactant glue used in the video

    • The glass does not block the entire UV band, plexiglass does. Normal or special glass blocks UVc, UVa, and partially UVb. UV adhesive can also be cured with purple light at 405nm or even blue light ranging at 435nm ~ 450nm. No special glass in modern windows can block blue light or purple light.

    • They don't block 100% though.

  • This guy’s narration delivery is spot on every time he really gets you excited with him and he’s genuine

  • I'm actually surprised it has any decent contrast at this brightness, considering liquid crystals can only block soo much light before they're effectively bleeding a huge amount of light through even the black pixels. But I bet if viewed indoors at night, the blacks would look like middle grey. As for the border problem, what I would do is simply get some cedar and cut them to line the front of the TV, raised an inch off the front so air can still flow to the radiator, with a nice cherry wood varnish and thin clear coat. Would give it a less conspicuous and classier look.

    • It really doesn’t make any sense to me how the color contrast not only wasn’t super blown out but improved. Yeah there’s absolutely no chance that the blacks will be super black at night though, I thought the only way to do that is with special led’s/backlights that can get very dim

  • I just love how he says "little bit of ingenuity" to accomplish this projects when you actually a goddamn amount of skill and knowledge to build things like this.

    • a little bit of ingenuity and copious amounts of a loo mini um.

    • @Coenraad Loubser wouldn't the sunlight shining in front of the screen cancel out the brightness coming from the back, making it a dim image?

    • I thought he was going to keep the back open so the sunlight could be the back light... Wouldn't work great on cloudy days, but should be perfect for sunny days!

  • To use this TV at night, you need sunglasses or you will blow your eyes 😂

    • I would have liked seeing some night footage

    • good idea in theory,but I have learned that water and electricity don't mix , especially when beer and good times are involved , tv's today are low power compared to older tv's so why to add the water cooler when the case is metal and gives enough cooling , your not running a plasma setup so hardly any heat anyway , what is produced gets dissipated through the case , my concern is the moisture that will be created by outside cooling and heating through the day that will transfer to circuitry and finally sounds you are from the UK and most times it's bitter cold and rarely a few hot days so why the huge cooling factor , heat sinks do the same job .

    • Haha discord light theme boosts my screen brightness by 9999%

    • @Aphilly215 is this a joke?

  • I'd like to see a solar -powered- brightened version, using mirrors and/or lens rather than LEDs for backlighting. not sure if heat would be even harder to deal with.

    • That sounds pretty finicky to me, you’d probably wanna use direct sunlight so it’d be moving on you constantly and probably require a pretty massive lens and set up. But using solar panels would be cool yet pretty expensive

    • @Анатолий Кияшко couple of cheap solar panels and a motor to make a simple solar tracker though everyone would have to move as the sun moves to follow the screen still.

    • No a good idea, you will need to turn reflectors or TV all the time - matching sun movement. Other light transitions solution will be tooo bulky.

  • Along with the things that you build, one of my favorite things about your videos is how geniuinely happy and excited you get when the thing that you're building not only works, but works just like you want it to. I always feel good watching one of your videos. Thanks for sharing your joy.

  • This was awesome to watch. I do enjoy seeing folks solving issues and building cool things. Kudos.

  • This is one of the few DIY channels that actually creates useful stuff, and actually puts a fair amount of thought and design into their things. It blows click-farming trash like 5 Minute Crafts out of the water!

  • I swear this is the only DIY channel that managed to make me go "wow" every single time...absolutely brilliant mind!

    • @HoldMyBeer lol ok then

    • @Nothing Here Neveeeeeeer. ^^

    • @HoldMyBeer hey I get it I hate it when people are too nice or too happy too, probably because I’m ass hat but down voting every time. Why be that annoyed that you dislike the video. You’re getting to emotional that you press a virtual dislike button just saying. Best to just go on with the day

    • Repent to Jesus Christ! “Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work within us,” ‭‭Ephesians‬ ‭3:20‬ ‭NIV‬‬ D

  • Have you considered applying an anti-reflective film to the outside of the glass to reduce reflections from background and peripheral objects (plants and such)?

  • "at your own risk" cannot be stressed enough: I took apart a TV that hadn't been plugged in for 4 days, shorted the biggest capacitor on a whim, and now have a burn spot on my safety goggles from the sparks. Monitors and TVs don't just have mains voltage, they have huge capacitors, and voltage amplifiers that can do enough current to kill, at thousands of volts, and hold charge.

    • "shorted the biggest capacitor on a whim" This is the electrical equivalent of, "I just pulled the trigger to see what it would do" ...

    • There is a way to drain the electric from the capacitors though right?

    • @Encysted very much appreciated

    • @Encysted true, much more likely to damage unplugged electronics than the other way around!

    • @pvt.edgy from what I understand, this advice came from older electrical devices with a power switch that was itself part of the circuit, so flipping it would reconnect the whole circuit, and ensure everything is at the same potential. With newer electronics, iiuc this is not a reliable way to dissipate charge, as especially on most PCs, the power button is a "soft" power button that only bridges a small connection in only part of the PSUs circuitry, momentarily waking up an internal chip to check power conditions. Because the device is unplugged, the PSU chip will see bad power conditions (if there's enough charge still left to wake the chip up and allow it to run), so it's not guaranteed to connect other internal circuits and dissipate charge in an places outside the PSU. But again, not a technician. P.S. en ESD wrist strap will not protect you from electrocution, it protects the components from you.

  • I was imagining it raining outside with like Star Wars Rogue One playing, and people sitting under some type of cover would be neat... would also like to see it at night

    • @Jesus is coming. Read the Gospel. I wonder what these accounts gain from posting religious bullshit everywhere

    • Repent to Jesus Christ! “Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work within us,” ‭‭Ephesians‬ ‭3:20‬ ‭NIV‬‬ T

  • Such an amazing project man! I’ve literally thought about doing this same thing. Or just making my own TV. I actually want to try modifying an OLED TV too. Maybe try adding my own heatsink, or water cooling. I really want to find a way to add a quantum dot layer too. That’ll never happen tho. Damn do I miss Quantum Dots! Hopefully QD-OLED fills that void in my soul. Anyways, things are much different with that tech, and making it brighter is much harder, and requires some major software/driver hacks. I did notice the backlight grid after you replaced it with the brighter lights. It just goes to show, how hard it is to make a decent backlighting system, while still maintaining good screen uniformity. Again, great video! I love your passion, and dedication to DIY projects. Also, thanks for giving me some education in this video. I always appreciate people sharing information.

  • Somebody: “It’s too bright out to watch TV” Matt: “Hold my home-made beer”

    • @TURKYM7MD nope, upon further inspection it’s just a plot to steal people’s credit card information

    • @ItselfBookshelf that's some strong ass fever dream right there

    • @TURKYM7MD well it’s obviously a porn bot

    • @Yuna🤗 What in the fuck is this

    • @boom shakalaka made out of brass

  • Try to make a tv with built in speakers, so you don't have to use two different remote controllers to make the volume level perfect. This because we have separate tv-audio and speaker-audio, which makes the audio difficult to fine-tune. I'd find it awesome if you could build all the audio into the tv.

  • I'd be very interested in seeing a comparison between this TV and the type of display that you see in some fancy bus-stop displays. Those are often quite large and visible in all outdoor conditions.

  • I have a suggestion: adding a battery level indicator on anything you can charge. I have a Bluetooth speaker that doesn't tell me if it's running out of battery so I'm interested to know if there's some sort of way to add a battery indicator to it

  • I can't believe these aren't a readily available consumer item already. I always thought there was a technical limitation preventing outdoor-brightness LCDs. This is one of the most practical DIY projects I've seen. I've always wanted to be able to go outside with my laptop and actually see the screen. Hell, even just indoors with the window blinds open, it's hard to see my desktop monitor.

  • I'm honoured to be one of the people who formulated and developed that GP200 silicone he's using

    • @Jon D I've never tested that but id imagine it will just cure a bit more slowly, the long term performance shouldn't be impacted by it curing slowly

    • @Nate does it have a hard time curing in environments with low humidity ? If yes, how much does that effect long term performance? Interesting stuff.

    • @Nate Congrats glad to see ur doing well!

    • Update: I now work for a bigger building chemical company!

    • In the time honoured words of Ray Liotta "..if you build it, they will come."

  • damn, nice job man, i have my own ideas on how id do this, but this is pretty awesome, nice brightness!! i was impressed, didn't think itd be that bright!

  • I really appreciate your dedication to "DIY". You could easily do all of this work in a fully kitted workshop with the best tooling available, but instead you are hack sawing channel aluminum and assembling the thing in a home office. Props man.

  • I could prob check math, but just an idea: is there a way to use an approx. screen-sized lens(?) to use sun as the backlight, after bouncing it into the right direction? And if that's still too dim - then boosted with reduced amount of LEDs? I always wanted to be able to work outside, and while it's super useful to know that you can literally reuse the normal LCD matrices with more powerful backlight, I don't really want to run 1.6kW+ 8h a day, day after day, and also hard to make it portable enough...

  • @7:15, I thought maybe he was going to use the light of his artificial sun, to combat that light of the sun. After 4 years of watching this channel, if it ain't water-cooled and brighter than the sun, he'll have nothing to do with it. Love it.

  • Sigh... looks like we need a new section on our website: 'products that will likely never sell, but will make crazy projects for DIY Perks easier' I will speak to the boss ;)

    • @shadowXXe yeah you are right and I am stupid :(.

    • @Prateek Chawla they meant selling items for crazy projects not selling the finished product

    • @Frog 4096 that's annoyed. It's 2400w I'm nz but we run on 220v/240v

    • @Prateek Chawla One year I got to go to a warehouse halloween party held by a company that does video screens at outdoor concerts. They set up one of their outdoor LED screens in the warehouse and played videos on it. It was the only light source and even at like 10% brightness it was damn near blinding. It. Was. AWESOME!

    • Alphacool: sponsoring DIY Perks DIY Perks: playing on a TV hooked up on a 30-stores building

  • The old outdoor screen will have a light-blocking canopy. If it is re-entered, the top of the screen will transmit light. You don't need to design LEDs and reduce the temperature of LEDs to dissipate heat

  • I see you I bet you could make the frontal area smaller as well by using bong coolers behind it (basically evaporative towers). With a custom cut piece of glass, it may even take up the same footprint as the original TV, albeit with a larger back portion

  • That is brilliant! I wonder if you could use dimmable LEDs for the backlight so you can use it in the evenings without burning your retinas out! 😅

  • THIS IS FREAKIN AMAZING. 👏 👏 👏 👏 👏 👏 👏 👏 👏 👏 👏. Man... you make this look so easy lol. I wish I could do something like this. Absolutely brilliant and stunning job. What a great idea.

  • Im gonna be honest, im not confident enough in my crafting skills to replicate any of your projects, but i love watching them because it teaches me what my house electronics are made of

    • thanks for being honest this time

    • @Deep State A.I. Lolllll! Nice

    • @Deep State A.I. I do that a lot when stoned 😂🤣

    • @the distinguished I was really high last night and made that up entirely. Sorry lol. Didn't think it would actually get a response

    • @Deep State A.I. oh cool! Youre selling them? (Not that im interested in buying just asking)

  • Great Project! Is it possible to boost a projector similarily? I have learned a lot from your videos over the past years. Thank you for that.

  • I love the homemade wooden feet in the beginning 😂 that’s why I always tell customers to keep the feet even if they never plan taking it off the wall

  • I’m curious, can this TV’s backlight be dimmed? I mean it’s great to have a tv that lights up above daylight, but what if the TV is kept outside until sunset and into the night? With that much backlight, the blacks on this TV have to be abysmal at full light output in dusk, not talking about being effectively blinded at night time. 😅

  • Been involved in engineering applications utilizing LCDs in hot/tough high vibration environments and it seems like you would destroy the polarizer layer with this build with the high light levels inside the LCD area. just the high light would make it hot and there’s no real way to dissipate the heat from the lcd/polarizer just from the LEDs. I might be wrong but I don’t think you could run this too long. Even it just sitting out in the sunlight might be enough to do that, too.

  • DIY Perks: "Let's start a new project". Pieces of Aluminium: *sweat nervously*

    • Aluminium, Brass and Wood: *Aww shit! Here we go again.*

    • LMAO

    • Al You Min E Uhm

    • I feel like at least once a month Matt goes to his local metal supply shop and asks "Do you have any aluminum u channel?" And then the guy goes "Yeah, how much do you need?" Matt just smiles and goes "Yes."

    • brass narrowly avoided becoming a tribute this time

  • The see through water cooling part in my opinion is cooler to watch then the actual tv i love how the water drips back down from the top and how you can see exactly how much water there is

  • Would love to see what could be achieved with a bigger budget for this, maybe not too much more, but at about $500

  • I'm looking into removing the 3H anti glare film on my Dell monitor and replacing it with a high quality acrylic sheet. Similar to how he's stuck the glass to the LCD. My question is would that UV curing epoxy be safe to use on the polarizer of a display?

  • This is a great idea. I love DIY projects and will keep this on the grocery list of projects. Thanks for the concept!

  • The sign of a true genius designer. Designs and builds a project no-one else thought of, which everyone loves and still ends up pointing out where he could improve it… thanks Matt!

    • just because you haven't heard of it, doesn't mean no one else thought of it. there are outdoor-specific tvs and there has been for a while.

    • I swear he amazes me every video! Pure genius!

  • Hmm, I wonder how well it would work to make a TV that uses sunlight as its backlight using different lenses and maybe mirrors.

  • 1:45 you have to have it unplugged for an hour because the capacitors will still be charged and if you're not careful they will give you a bad shock

  • How well does the remote work outside? I feel like the sun would interfere with the infrared light most though remotes use

  • That's amazing! I can't believe you managed to make that so cheaply. Does it take a lot of power to run it?

  • You never end up making any of these, but you watch them for the ideas that they give you. That is why DIY Perks is so good.

    • @Tomas TBH if you were actually an engineer you would be in awe of his ability to imagine something like this, and then to actually build a functional prototype. This was not created for you Tomas. It was created to showcase his abilities. To show no matter how unorthodox an idea may be, there are no limits to what can be accomplished. I fear the only thing stupid here is your inability to imagine. That would be a horrible trait for an "engineer". Peace out.

    • @SirDella Not the daylight ones, but the ones based off old TVs. In my case I used old netbooks and LED stripes to build my own panels. The concept itself was enough to serve as a reference.

    • @Luciano Rivera which panel?

    • True calling it plain dumb just because it looks to be something else is not smart and the computer he talked about many people build their pcs into their desks as long as the cooling is efficient what's the problem?

    • @Tomas """ Im an engineer with a degree """ having a degree does not always make you smart. If you do not understand the concept or have the ability to see what this does or can do then you are not smart. I can explain it in great detail for you. Just let me know if you need help understanding what a 1500 watt super bright TV does.

  • I think one thing that could have been really cool to add would have been a fish tank light and a bit of food colouring to make the cooling system illuminated as well, which would be really cool for night time use

  • Appreciate the huge effort you went to build this and you are certainly very clever, but there's no way I am even going to attempt anything like that. I'd be off to the shops to buy one rather than do all that, but at the same time I don't really think I want a TV outdoors. It was entertaining to watch you being so excited about building this though. Cheers.

  • Mate, you blow my mind with your ingenious ideas for projects EVERY SINGLE TIME! I have no words, you rock!

  • This is the first DIY PERKS video I've ever watched, and I've been watching ILaward for years and years! You definitely earned my subscription! You're very thorough & a delight to listen to!

  • I watch these videos and often think "I could do that too!" But dude I would NEVER get all those air bubbles out of the glass.

    • If you setup your glue-up right, you can avoid trapping any bubbles in the first place, kind of like thermal paste.

    • @FindLiberty I agree. Vacuum really sucks! (Nice pun, BTW)

    • @Renzo John Could a large plastic bag or wrap and a vacuum cleaner do the job? Too much vacuum might make the LCD panel become sad and cry out its liquid crystal fluid, and that would really suck. lol

    • Huge vacuum chamber that can fit the entire thing: Am I a joke to you?

    • UV cure - That allows all the time you'd need.

  • I'd love to see how bright it is at night time. This is one of my favorite videos. So freakin cool, well done bud.

  • I have watched Matt's vids all the time and it inspires me to try with stuff I have laying around but more importantly it inspires me to push boundaries of what can be achieved by doing the simple stuff like learning to Look and Listen carefully which is a Hard skill even adults struggle with apart from kids. If you Look , Listen and Recycle you get = Amazing Recycled Projects and a Brilliant Outdoor TV ..Man this thing is sweet. @Matt may I suggest you get waterproof capped AC Inlets / Joiner(Don't know the exact name) but it prevents rain water getting into the contacts that cause oxidization on copper pins.

  • I’d maybe add some anti glare foil on the glass to reduce reflections, however at such incredible brightness idk if it’s really necessary

  • I was thinking that if you made a way to channel sunlight into the back, you could have the brightness adjusted by the brightness of the sun. It would "auto adjust" to the level of daylight. You could then use cheaper and less LEDs for night time use.

  • Hey Matt just a quick comment, I absolutely love your videos man. Please keep up with the fantastic content and more than anything, your infectious and seemingly endless energy for tinkering! Love from Finland!

  • That is a fun project. I'd be concerned with the cooling though. Aluminum dissipates heat very quickly, but it's not very uniformly unless the water is evenly distributed across the panel, I'd be concerned for hot spots.

  • The acrylic panel will let mold grow inside since it will have access to sunlight. I think putting some bleach in the coolant or just blocking the acrylic can help to prevent mold.

  • Would it be possible to have a way to control the brightness level so it could be used outdoors regardless of it being night or day?

  • I love how weird this is (despite not really feeling any need for an outdoor TV myself) Is it possible to measure the brightness by interposing a neutral density filter of known properties?

    • @Damn Cat general kenobi

    • Fancy seeing you here shrimpy ol boy 🧐

    • @Finn Jaeger since it's outside i'd imagine FHD (1920x1080) would be sufficient or if you convert it to a VGA signal you could read it out with a Teensy 4 since it's analog it'd be way easier as it'd be reading r g b each clock and setting the next led(s) then compare which value is higher ( r g or b ) and use the brightest to set the led to *

    • @BH4x0r To do UHD live image analysis and then drive the LED panels ? maybe not sure , its not that easy. the curve part is pretty easy thatsbjust fitting PQ into the native controller response of the display, but even that with a Pi it will be hard , this takes quiet some processing power to do, modern TVs use AI as well, maybe more of a job for a jetson but yea its not going to be easy

    • @Finn Jaeger i think a Pi 3B or 4B would be powerful enough for that, use a HDMI splitter to feed the screen and the pi

  • Can you do this with a small display like a laptop screen as well or is there a difference in how they work?

  • Only thing is you miss the beauty of nature when you're watching a tv outside 🍃

  • I figured you were going to go the route of using a photosensitive cell to determine how bright it was outside, and if it's above a certain threshold use the sun itself as the lighting source, otherwise mixing the sun and a backlight source dynamically to provide the best ratio

    • I'm not sure how you could aim the sun to be right at the screen, as well as reflect back, but it does sound like a fun idea.

  • Interesting project. I just repaired a LED tv backlight last week. I wonder how good repurposed burned out Led light bulbs would work for illumination?

  • Keeping the price low gives projects constraints, and usually the most interesting engineering solutions are created when constraints are the highest. Funds can make or break a project but off-the shelf pre-engineered solutions can be a bit boring.

    • yes exactly. resource constraints are an integral part of good engineering.. finding the sweetspot in terms of resources to viable performance ratio is key.

    • "In order to think outside the box, one must first have a box."

    • Exactly

  • Looks amazing. Can the glass reflection be reduced?

  • When the silicone sealing the tank fails, will the voltage converters and PCB burn out first when they get drenched, or will the backlight burn out first due to lack of cooling?

  • First off, Well done, truly fantastic idea and executed spectacularly. Bravo! Secondly, I have a few questions. What's the power draw on this bad boy, like the whole thing not just the LEDs which no doubt make up for 99% of it? Have you used it indoors and does it throw an image onto a wall? That question leads me to my third and final statement or should I say challenge. Do this same thing but as a projector. Good luck!

  • New idea, make a outside TV using just the Sun and Mirrors as backlight

    • @Mr.Magnificent Not that I'm all for the idea, but another thing would be to have the redirected sunlight pass through a pane of infrared-blocking glass to reduce heat.

    • @Pollu Pora Yea, you need a lens to concentrate light on one single spot (which is not the goal here), however you dont burn yourself when you hold your hand in the sun, do you?

    • @Mr.Magnificent have you ever looked at the sun wth binoculars or a scope or anything that concentrates the light, havent you seen what this guy has made in the past ? A big ass lense for burning stuff using the sun

    • @Pollu Pora the heat emitted from the leds in this video for sure is much higher

    • @Raghul Akash of course it wouldn't be perfect, but it would still probably be a nice experiment, to see how much light a mirror set up reflex camera like behind the panel could provide when the sun is high up.

  • Im really suprised that the display didnt look massively washed-out. Those crystals are damn effective, more some then i thought.

    • @TemporalOnline it would be literally painful to use at night so the point is kinda moot ;p

    • @Deniss Kaskurs I think he means automatic dimming of individual areas that were meant to get darker, which were/would be controlled by the tv and now are always at 100% brightness all the time.

    • It is easy to add few dimmers.

    • But how it looks at night is the other question. No local dimming, nothing.

  • Also i recomend putting a mat screen protecter over it to make the reflections less intrusive

  • $350 would be a deal. I was guessing that it was higher. If I took this on, I would take some of those extra cost options and try to make two for under $1k and try to sell the extra one for $1k to a friend or family member. It pays for your fun project, not your time, and you still get a cool toy.

  • How cool would it be to have a functional fish tank in the back and make the whole tv rotatable so you can hide the black screen when it’s not in use and have an outdoor tank!

  • From the first frames I though you want to use the natural sunlight as back illumination. If you can redirect it efficiently (with a couple of motorized moving mirrors?) to the diffusor, you get all the crazy brightness for free: no power needed, and much simpler cooling would probably do. And it would have the natural brightness adjustment. Hmmm, sounds like a fun idea...

  • This sounds like something Linus would do for his house upgrade project

    • linus is a guy who wastes money to make random pc's that they are just gonna tear apart in a month to use for parts on another pc

    • @Casey Thimm I watercooled my air

    • An over-volted TV for a overclocked PC

    • And other than the actual seats, you could probably build it entirely from a run to some pool/lawn & garden/automobile stores.

    • @Casey Thimm : You know what? Water-cooled seating would actually be a good deck upgrade for places that actually have summer. Find some sort of quick-fitting for water hoses, mount them just below deck level so they don't get stepped on, with a bigger funnel surrounding them as the water return, run the return water through some filters, into a tank, then some radiators, then a pool pump, build some chairs & such to plug in, and you have water-cooled seating.

  • Your projects are incredibly tempting to do, but they appear deceptively easy, the trouble seems small and easily overcome, but when I'd do it, I might not find the right glue, or I couldn't get the bubbles out, or it would in the end leak just a bit... so, respect, as always.

  • This is absolutely brilliant (pun intended). Seriously love this one.

  • Next you should try making a locally dimmed custom backlighting!! Maybe even miniLED(2000+ zones, however you get there)? :D

  • Would have been good to put an LED dimmer on it, so you can modulate the brightness, or tune the heat down if needed (Australia here)

  • I’ll start by saying I design LCDs for automotive OEMs (not trying to brag at all). There are a lot of great ideas here, but the one thing that VERY much concerns me is the waterfall cooling. LCD polarizers are made from PVA, and they are easily destroyed by high heat + high humidity (even high-temp automotive-grade ones). If you want to keep the water cooling, you have to seal off the LCD (color filter part). It’s a good idea to do this anyway since the display will be outdoors. I’d also recommend adding a shroud around the TV. This can tremendously help with outdoor viewing. Also, if your TV backlight is still working, you don’t need to scrap it. You can just add additional LED strips inside. Also, you can buy copper refrigeration tubing and run it directly behind the LED strips, and then run water through the tubes for cooling. Use a conductive paste from a hardware store (not expensive CPU stuff) between the copper piping and the sheet metal housing. Lastly, if you can apply an anti-reflective film to the front glass, it would help tremendously, they can be expensive. However, DON’T use an anti-glare film. They make the display hazy, especially outdoors.

    • Hey can i ask you some questions about lcd i didnt find anyone in person who can answer my question so id be so thankful if you reply

    • Hi mate. Not the best place to ask you this question but i've made my own infotainment system in my car and I use a permanently fixed samsung galaxy A50 on my dashboard. I have it for a few months now but summer is coming and I have relocated the phone battery due to heat concerns for when I leave the car out in the sun. But do you think the screen can hold up the temperatures in the summer? It's a super AMOLED according to gsmarena.. Would you recommend any type of cooling?

    • @Hugh Jass Studios Sharp is always doing something interesting with their technology. I still think about their RGBY

    • @Hugo Fernandes I was thinking the same thing, the deal is each of the panels that use full array local dimming use chipsets that are designed to understand the contrast of the picture and dim the proper LEDs appropriately, in a DIY setup like this the LEDs are based on how you created it, and if you used a recycled chipset it would only correspond to the number and order of LEDs it was originally designed for, you would need the software from a recycled chipset to understand the contrast for the image in the first place, then would have to customize it to correspond to your exact LED setup, however the overhaul of preset base values required for this task would be a nightmare to say the least, would practically have to redesign it from the ground up, unless you made it a point to simply design the LEDs to exactly how the manufacturer designed it to work to begin with, would probably be the only practical way to do it
