Well... there's CRT monitors, LCD's, now Plasma. I researched on how Plasma screens work, and it says there that each pixel is made of 3 subpixels, with each having the primary colours. Each subpixel is like a small neon light. It has this really small tube filled with neon or xenon, and one side, the glass tube is coated with colourful phosphour that emits visible light when the UV light from the neon gas hits it. Anyways... well i thought that instead of having these thousands of tubes in a huge array on the screen, to modify the LED. Since the LED is really that a small piece of silicon, and what makes it so bulky is the plastic cover that directs teh light. So since the LED has enough brightness, just make it really really small, so it gives off just enough light. Since LED can be red, green and blue, make the entire screen with LED's printed on an array of invisible conductors.

What's the big deal about this? Well Plasma screens use a lot of wattage. And there is a possibility of destroying the pixels, either mechanically, or that the neon or the phosphorus inside degrades. A lot of heat is given off also, and it's kinda scary when u put ur hands behind the screen and u feel all that heat. On the other hand, with the led's, if they are powered corectly, they are theoretically nondistructive, they never fade away or burn. They normal red led uses around 10mA and if the size is decreased that would get close to 1mA or even less. That's my idea, i know that LED panels were made, but they're big and they use full size LEDs, which are not very good for a room size screen. Tell me what you think about it, and if it would be doable. I don't mind any criticizing. That's how i get better.

Ive often thought of that my-self. How much light output could you get from an LED with only 1ma of current??? the brightest leds that i have seen are usually have an awful viewing angle. I think that that might end up bieng the problem with LEDs . Also dont plasmas and LCD have backlights? Can Leds be backlit????

I think its Toshiba who is doing it, or Samsung or one of those biggies, they are making LED displays using what they call Organic LED's which I guess are LEDs that are made of organic material, and are really small.

yup, there are R&D works ongoing to develop such product.

It's Kodak that pioneers it and everybody is following the pattern.

There's downside to using LED, or OLED in this case. LIFESPAN. OLED couldn't last as long as LCD or Plasma. That's the problem. Nobody want to buy a TV that blown up after 2 and a half Lord of Rings DVD routine, just don't sounds right...

Secondly, they are having the hard time with White LED. And we are talking about a minuscule white LED that emits bright light that are visible from a far. The mixing of RED, GREEN and BLUE chemical to form the LED seems hard but there are development on it, too.

OLED production method have yet to fine the right ORGANIC material that are lasting and not as heavy as glass substrate as of LCD panel. Somehow, the recent development shows that laptop LCD display had shifted to using white LED back light instead of cold cathode fluroscent light in the production of thin and light notebook computers.
