Plasma, and LCD televisions will soon be a thing of the past, imagine a television screen as thin as a piece of paper that weighs no more than a few ounces. Or, so flexible it could be worn around your wrist and is virtually indestructible.
The primary benefit of OLED displays over traditional LCDs is that OLEDs do not require a backlight to function, and consume less power during operation. OLED displays are expected to be more efficiently manufactured than LCDs and plasma displays.
The AMOLED technology have full layers of cathode, organic molecules and anode, the anode layer overlays a thin film transistor (TFT) array that forms a matrix. The TFT array itself is the circuitry that determines which pixels get turned on to form an picture.
The fledgling technology of making ultra-thin displays using organic light-emitting diodes (OLED) is starting to bear fruit finally with Sony, Samsung SDI and other makers introducing new applications.
OLEDs are made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. The OLED materials emit light and do not require a backlight (unlike LCDs). In fact OLED TVs are better than LCDs in many ways:
- OLED TVs have Faster refresh rate, better contrast and better color reproduction.
- OLED TVs are really thin - the Sony XEL-1 for example is just 3mm thick. The new prototypes by Sony are merely 0.3mm thick!
- OLEDs have a much better viewing angle - almost 180 degrees.
- Better for the environment - they draw less power, and contain no bad metals.
Or perhaps the OLEDs will be so thin and transparent that they will just be invisible when not in use - you'll just see the bare wall, but when lit up, it'll display your TV picture.
Just a matter of time until we can star archiving our LCD and Plasma Tvs.
