![]() The more contributors the less cost between everyone. Maybe there is someone here willing to shell out $100+ though himself to get the project running. I am willing to pay at least 20-25% of the cost myself if I have to. ![]() I don't think anyone wants to shell out $100 to try something that might work, so if anyone thinks this is a good idea and is interested in contributing let me know. If anyone else is interested in this project and wants to contribute to help get this project off the ground asap sign up here and the cost of the materials can be split between everyone interested and the results (with pictures/screenshots) will be posted here. My goal is to make a 10.5' x 5.9' rear projection tv with my commercial home theater projector A single layer would probably create the brightest picture though. I want to combine it with a matte/frosted clear paint and possibly transparent black dye and would like to try in layers too. There is a clear paint with microsphere beads in it. I think I may have possibly found away to make a DIY versioin of the Vikuiti black rear projection screen, but it will cost at least $115 just to try out with experimenting. The screen trumps every material I've tried it's incredible. The screen is basically a black absorbing layer on the back of a matte acrylic sheet with a thin diffusion layer on the back with millions of microspheres (glass beads) that redirect the light creating a bright, high contrast image with a wide viewing angle. Too bad that a 95" version costs about $5,000 and even a 60" version costs more than a 65" HDTV. I have a rigid rear screen sample with the film on it. ![]() That 3M film is most likely the one used in Vikuiti's black rear projection screen. I basically just need a few percentage more to project the images up against each other on the big RP panel seamlessly. I suspect that I need a lense in between to like "focus", is this correct?Īs I don't want to project each panel much bigger than they already are, I hope that it can be achieved with a very short focal length. However if I keep sheet at a distance, the image becomes more blurry the farther away I pull the image. If I backlit it and keep it just up against the panel, the image becomes sharp and looks fine. However due to the lack of knowledge within this technique, I don't really know how to project a sharp image onto it. I tried testing with a simple transparent sheet with a color image. I've already acquired some plexi glass samples, off one is a small piece of RP dark plexi glass. I'm planning to use Rear Projection in a short distance, hence the post in this topic. However, to get rid of the borders from each panel. This way, all of the tech is on the same page, and I just had to take the LCD screen out and reconnect all circuits.I'm planning to create a screen made of 4-6 smaller panels and software to combine it into one big image. The LCD screen from the computer, although bigger, would be more time consuming so I used a 7" LCD TV I wasn't using and hooked it through the Video out on the Rear-Projection. Thank you so much for your response, I pretty much came to the same conclusion. (something is going to break the moment you give it power) If you use two totally different shoes that look completely different. You can use two different shoes that look kinda the same and not get noticed (something might break) you would then have a situation that is basically the same thing as two different shoes. you would still have to reverse engineer the lcd control board and the video preamp section of the projection screen.Īny mismatch by adding features or subtracting them. If your lcd panel in the laptop is fully functional. Is it possible with your specific equipment? i dunno. but you have to be aware/awake to use the right pieces together. These types of tricks/hacks are possible. ![]() Some lcd panels might require in-y in the middle area and it will/could do the exact same thing as cracking the lcd panel. This wont look right when you first use it. there isnt any liquid in the square, and the voltage is going to try tearing the square in half. If i have a square and i zap negative voltage into the side frames. If i have a square and i zap positive voltage into the side frames. How the board wants to control the lcd panel must be known.īecause not all lcd panels are operated in the exact same way. How to control the lcd panel must be known. The lcd projector and lcd control boards might be a match though. I would think the crt and lcd control board are completely different. Havent reverse engineered an lcd projector control board. Havent reverse engineered a crt projector control board. I havent reverse engineered an lcd control board. The easy answer is to use the lcd board and then match the voltages with the impedance and voltage requirements of the lcd control board. ![]()
