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

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

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

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.

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?

You focus a great deal on aesthetics, but this shows that one of the great perks of DIY is that the projects can be optimized for whatever matters. You did really clever work to get the price so optimizaed, great stuff!

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.

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 just love how happy he gets when he completes his projects and see them work.

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.

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.

Hey Matt that is really great fun, the only thing I would add extra is a simple inline water flow sensor that would switch off the led panel in the event the water pump fails, its about 5 quid and worth every penny, I use them on my C02 Lasers to save the plasma tube from overheating....Really great fun your projects as usual..Well done.

This is incredible! I might need to steal a couple of these ideas for something I'm working on. Does the optical glue adhere to acrylic?

If you designed it on a swivel mount you could 'decorate' the back and make it into one of those decorative waterfalls so you could switch modes when you don't want to watch TV.

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

(1:28) I agree!!! That's also why I often would just buy broken items, or used items that are in bad condition, if I want to modify them.

About that CRI part. LCD colors generally don't benefit from high-CRI backlight. For best color rendering, the emitted r,g and b should have as narrow a spectrum as possible, and smoother spectrum of high-cri sources is not helping with that. The best backlight for an lcd is an RGB light (very low CRI) with led colors matched to srgb's base wavelengths, both from color and from efficiency perspective. The efficiency is a bit tricky, i've heard that high-efficiency green leds are a problem. Quantum-dot technology is (i think) a way to emulate rgb backlight (concentrate the spectrum around these key wavelengths) with a white-led-like technology (blue led with a photoluminescent stuff on top).

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

Damnit! I was about to go to sleep and now I am laying here contemplating how critical it is for me to build my own outdoor TV for my non-existent yard.

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