Oxide TFT comes to the fore with FPD growth

April 4, 2012 — The flat panel display (FPD) market’s growth is pushing next-generation display technologies forward, as profitability worsens for amorphous silicon (a-Si) thin film transistors (TFT). New core technologies are needed to improve the performance of TFTs.

Thin film transistor technologies include a-Si, low-temperature polysilicon (LTPS), organic, oxide, and others. Also read: Top 10 LCD manufacturing trends of 2012

Samsung Electronics signed a license on Oxide TFT-related technology, the transistor that achieved rapid development of technology between the last 5 years. Oxide TFT enables large-area and high-resolution displays, which can be applied in advanced products like no-glasses 3D TVs. The materials can be processed at room temperature, enabling flexible displays on a plastic substrate.
