Building an ULTRA-BRIGHT water-cooled TV...

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

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

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

I watched this video a year ago when it came out, still one year later it's still amazing to see how vibrant and colourful the TV you built is. Truly amazing work!

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

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

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.

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.

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

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

A version 2 of this project would be interesting. Like if the screen and cooling unit fold together like a laptop. That way it would supply its own stand. Then add wheels and an extendable pulling handle like luggage. Great video as always

At first I thought this was silly, and then I realized how fun it could be to sit in the yard and game or watch a game!! Actually useful!!!!! It looked amazing too. You could add a black metal bevel on the outside for the border!

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.

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!

I’m always amazed how you make it look so simple and easy to do but really it’s a work of art only a handful of amazing people can do

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.

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’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.

You can stack identical LCDs to multiply their contrast. So, instead of high brightness, you could use the water cooled system to make a display with a million to one contrast. Also note that FFS (All IPS is actually FFS) displays have better thermal tolerance and their blackout temperature is much higher than MVA.

you have such interesting and unique ideas, I wouldn't be surprised if companies took some of the things you've made and make them commercial. something like this would be absolutely amazing
