OLED Technology & the Environment - Part II
One of the reasons I love working in OLED technology is because it has the potential to reduce the environmental impact of displays.
An important advantage of OLED technology is that no heavy metals are used in fabricating the displays. LCDs commonly rely on compact fluorescent lamps, containing mercury, as a light source. Mercury is toxic to humans and animals. Since OLEDs do not contain mercury, they can reduce the environmental impact of displays and lower disposal and recycling costs.
Green Tip of the Day: Don't throw away your old electronics with LCD displays - there's mercury in that panel!
One of the main attractions of OLED technology, compared with LCD, is that it is a simpler structure. Both OLEDs and LCDs use LTPS TFT substrates, but OLEDs require fewer materials to create a full-color display. Schematics of typical AMOLED and AMLCD displays are shown below. Fewer materials used in OLEDs results in less waste to be disposed of or recycled later!

Comment: safetinspector - In most OLEDs, there are at least 3 distinct layers of organic materials (and usually several more). At least one layer is doped to cause colored light emission. The specifics of the layers depends on application. You can find more informations here: http://en.wikipedia.org/wiki/Active-Matrix_OLED and at www.kodak.com/go/oled. Thanks for the great question!

Comment: What is between the LTPS TFT Substrate and the Glass in the AMLCD schematic?

Comment: OLED is the future. In 3-5 years OLED can compete against LCD and Plasma. Check out this OLED Info website: http://www.oled-displa.ynet
