Bricolage très moche et inutile aujourd'hui avec la technologie micro et nano leds tout ceci est inutile.
Hey Matt, Is it possible to turn an old TV into a paper-like display for showing artworks or photos, without anyone realizing it is actually a TV displaying them (i.e., making it look like paper)?
For a project I need a transparent oled, but they are expensive af. With all the ideas I came up with, this is pretty much exactly what I was thinking too, using a projector to have localized backlighting for an lcd mod. But my plan failed because there’s no way I know of to have the blacks to be actually transparent, I’d need a programmable diffusion layer, with the same resolution as the screen… I think I need to wait for toled to become less expensive.
increible 😮
muy interesante
Can you make an gaming monitor with this method? And show us the results ? Im sure it'll take less power than the dual display monitor you built and would be usable and affordable
that tv is spying on u
I actually think it looks more natural. Based off of what I can see at least
Bro reinvented a rear projection TV for a future we never got.
Im not sure how i missed this video, this is actually ingenious and even though i do have an oled for my PC this blew my mind . Im a hobby builder myself and while im extreme janky i have to give you absolutely top marks for creativity and sheer technical skill to pull this off. Sure its unsightly but its also basically free i would have never thought an LCD could look so good, you were 100% right about the fact that even being compared to oled as actually kind of insane
SCIENTIST LEVEL DIY....
God damn I hate background music. Does YouTube automatically add background music to every video because it seems like its impossible to find a single video that doesn't subject us to this horrible background noise. Why can't I find any YouTuber who dares to be different.
cuanto trabajo pero fue genial y me recordo la emocion de crear y sentirte inventor jejeje lolco
Can we make tv out of mobile screens ? @DIYPerks
👏👏👏
This is one of the best videos I've ever seen on YouTube.
Why not use some lenses to bring the projector closer to the LCD and have like a CRT TV box out of wood? (and fix the image with OBS in case it gets distorted by the lens). This way you don't fill the room with light and keep the awesome effect. <br>PS: I left this comment for future me, in case I finally get to start this project.
undersold it my guy. parlaxing? you built a 3D screen
What if instead of the projector you use an other LED TV, maybe add more LEDs to the TV or maybe even remove the diffuser to get the most light possible to make up for the loss due to having 2 LCDs on top of each other.
Looking back at this after a year, I had some thoughts. With one of those extra thin and bright UST projectors you can get nowadays, a lenticular screen, and an LCD panel like this, you could make a really incredible TV.<br><br>You’d project light onto the screen, then the lenticular screen would send light straight forwards into the LCD panel.<br><br>The question is just whether the cost and complexity would be worth it, given how impressive and expensive those UST projectors already are.
is it good as qled tv? color and contrast wise?
I am always amazed by your ideas. How you build something from a common item into a master piece.
Honestly that’s clever
Can you DIY mini led from old led tv?
Why is no one selling those??
This needs a Version 2 to improve it.
such a useless build for a living room...yeah sure let me have a PC always on while trying to play on my console that needs a capture card to work on the PC since the backlight needs OBS to work.
most clickbait title ever, but cause its diy perks i actually believe it
Ta bastante bien, pero el problema es el consumo de energía y el problema de distancia del panel.
Could this be used for a rear projector tv?
just buy an used oled at this point.
Holy shit
"mom i want a oled tv" "we have an oled tv at home" *the oled tv at home:
this is cool man. i hope you continue using recycled parts in all your projects
Super cool, just trying to think of a way to streamline it a bit more so you dont have to use two HDMI ports on a dedicated PC, something to process the video signal to the projector so you could use a HDMI splitter or something and just use one port
the way this guy explains things makes me feel smart myself
Try OLED?
This is crazy! <br><br>To your note on "why did no one do this before", its because like with anything, TVs went through trends. After having of dealt with big, clunky box TVs, that when Flat screens became a thing, they became immensely popular as they were seen as sleek and easier to handle. (not to mention taking up less space) <br><br>I think the bigger problem was just the trends wouldn't allow for a thicker TV that had the ROOM for an extra bit of technology. Even if they had OBS or made their own in built software to do the same thing, very few people would buy it because it wasn't "Trendy" enough. Only recently have trends shifted from just flat TVs to wanting bigger, more accurate TVs but even then, most people are still just used to flat screens being the norm now.
great idea ! <br>thank you.
This looks great, but I don't understand why it is better than a projector by itself (apart from the resolution). The colour and contrast look great - why are they better than the projector? Why isn't the image as washed out by room lighting as using the projector directly?<br><br>I've thought of several possibilities, but haven't worked out the answer. If it's because the screen is darker, would projecting onto a darker wall be just as good - I doubt it but I don't know why. If it's because you're projecting onto a smaller area, would that be doable projecting onto the wall? Does the screen let light through from the back more easily than it reflects room light from the front?
I don't understand why you would keep the diffuser. That makes no sense. That would just reintroduce glooming. You WANT the sharp edges and align them well.
that mind-blowing last twist using mirrors at the end tho .. I logged in Youtube just so I could comment your video. Jesus, there is nothing holding up this man and his craft !
Es casi igual a un aparato que es de color blanco que ilumina una pared lo mismo igual a una pantalla blanca y que es un computador entonces<br>Es para la iglesia para que la gente leer y las las letras de canciones
Ingenious, thanks for the idea, or rather, the ideas. That's excellent work, my friend.

“- Mom, I want oled tv<br>- we have oled tv at home”
Just buy oled tv
With this solution you'll always be limited by the size of a TV's LCD screen. One problem you haven't mentioned is the delay between images, (TV vs projector) and the spherical distortion of the projector's zoom lens will also make alignment difficult, along with potential dimming issues with each color on the DLP projector's DMD chip, even though you've removed the color wheel.
My parents still have the cabinet from a really old rear projection TV. I think I want it now
I know this video is old but I thought you might want to know they did make a rear projection tv like you describe I owned one, the toshiba 46H84 and 51H84 series, Im sure there is more, that said Id rate it closer to a ips it looked really good but not as good as a normal rpcrt, its crazy how people justify new tv tech by outright dismissing crts, absolutely nothing is better than crt, with a large amount of processing inc hdr emulation the closest I have found is oled followed by ips but "stock" its vastly oversaturated but does produce true black, ips is far better and closer to a crt but lacks true black, due to this oled wins overall, maybe high end models are better because I can see oled having the potential and is the 1st tv tech to come close<br>CRTs have rich deep color, warmth and contrast that no tech since then has touched, its also more realistic and soft, everything after was and is way to sharp and glossy it messes significantly with lighting making the picture look fake, it can be mostly fixed however using a ips or oled with extreme processing or sometimes hdr content but out of the box nether are no where close to the quality of crts<br>I do love the video and was really cool but atleast over youtube it looked vastly better than what I have seen and honestly maybe even better than crt its the 1st time I have seen something "crt like" in quality still to glossy but sharp without artifacts and rich warmish picture, still not as good as crt in this way but in terms of detail it wins hands down
So we are going back to crt style tvs😂
now how do I put this in my room
Mad engineering
A working TV, no matter how old it is, will never be free in my country
So cool how unc keeps finding neat tech projects like this one
Please help me understand: how does the use of OBS get rid of the alignment issue? Whilst the illumination map could be an improvement, won't alignment and the difference between the panels still be of hindrance?
I just came back to this video to tag @linustechtips because he is so obsessed with high contrast and new TV technology, so a collaboration would be worth it.
reinvented the crt. amazing
crazy aeyes
now what would happen if this was exhanged for a projector that hits like 12000 lumens or something like that? could we see oled contrast with mini led brightness?
Tal vez puedas hacer un mueble donde el proyector apunte hacia abajo y todo este por dentro
This is basically like Sonys new micro RGB TVs, but before they were invented, cool!
The gap below the tv would be great for an integrated sound bar
Tienes Algun Proyecto por el Cual se pueda mejorar las pantallas de Tela o Similares que se usan en un Proyector LCD comun.<br>Te consulto porque Probe con una Pantalla Totalmente Blaca, otra Blaco Mate y Una de Color Gris Brillante, que hasta ahora es la que me dio mejor resultado.<br>Pero viendo tu Video, se me Ocurrio que Quizas usar una Pantalla negra brillante, daria mejores negros, pero fabricar una No esta en mi presupuesto, ni habilidades...<br><br>Muy Bueno Tu Proyecto, por Cierto, a pesar que No me serviria a mi...
...Awesome—I’d always wondered how to do that, and your video pulls it off in a practical, simple way. Excellent...
Same idea of rgb mini led tvs, nice !
WoooW 😮.. ❤
Parent it
I wonder what motion clarity would be like? Maybe some form of strobing or crt beam simulation could be added?
Would this work on a 3D tv?
Mas se a tela esta boa os leds so trocar pq desmostar a tv🤔
You're a genius! ❤
Nothing new here, but nice to see a DYI of a dual modulation tv. Sony color reference monitors for broadcast work like this
Truly brilliant
In addition this project is a good representation of just how many mini LED or even on the micro scale you would need to achieve OLED level of blacks without halowing. We're not there yet, and perhaps LCD never will get there.
Topnotch project dude! I learned a lot from this even though I don't build it. Simply fascinating!
bonjour! votre vidéo est cool, j'ai une question à vous poser ! combien d'électricité consomme votre appareil?
me watching on a 16years old tv: hmm yes that looks much better.<br>I was even impressed by how good it was on my ass tv that shows black as gray
believe it or not im watching you now on that ancient Lg TV LOl
Can i get a conv with you please
The fact that this was made by scraps from a tv etc, this would be a legit perfect CyberPunk setup once perfected.
This is exactly the principle behind Hisense ULED! They use two LCD layers sandwiched together. The first creates a hogh resolution ligh map, and the second produces the color
What about one of those mini projectors from temu projecting behind an old flatscreen for a PC, perhaps boxing that one could be easy? 😎
I love this so much... Actually I love your channel even more! It's just a pity there isn't a way to box everything up and still get the same result
please buy a mini led tv
WAOUK😍😍😍
Hats off brother for this incredible DIY
Amazing talent, I was thinking of this to make myself and found someone already did it ❤
It's insane that my phone screen is catching the changes so well.
so you are using 2 different outputs, one for TV 1 for projector
You sir are my favourite youtuber.. I truly aspire to be like you!
make led tv using led lights...
You should patent this bro
Would be cool to se a version 2.0 of this, maybe a 98" tv and a short throw projector and then enlcose it with dark panels
Now, you can update it to a "True-RGB" one.
It somehow reminds me of the CRT monitors and TVs
can anybody tell me which game it is at <a href="https://www.youtube.com/watch?v=qXrn4MqY1Wo&t=915">15:15</a> ?
My DLP Samsung the best picture of any TV I have ever owned.
So you've made a RPCRT and LCD TV hybrid. Amazing work
That’s genius
