Oxide TFT - Page 16

Samsung Electronics has developed a new Amorphous Oxide TFT technology, which can be used widely to next generation display semiconductor devices - LCDs, AMOLEDs, solar cells, LEDs and sensors, flexible and transparent displays, and more.

Samsung changed the existing single channel structure into channel structure, which resulted in faster electron movement (3 times faster than existing tech). This means that the screen quality is improved.

Researchers at Purdue University and Northwest University have developed a flexible and transparent transistor using a combination of zinc-oxide and indium-oxide nanowires. These invisible and bendable transistors actually preform better than conventional transistors, and can be easily built onto sheets of flexible plastic.

Their work also revealed a promising new development in the control of OLED's. They found that when conformist nontransparent transistor circuitry is placed around the OLED, it could be inadvertently be emitting its own light. But these transparent transistors can actually be placed beneath the crest of the OLED. This would help to obscure the already invisible transistor, but making its light source a part of the OLED's light source. The transistor would control the OLED  as well. There is also the added benefit of less space used, bringing the hope of a higher resolution display with a small dot pitch.
