It brings oxide technology to performance


Each pixel of a display is controlled by at least one transistor, and is higher in the driver’s level. The transistor technique determines that the performance protects energy, switches rapidly or especially bright lights. The thin film transistors (thin film transistors, TFT) include Amorfema Silicon (A-SI), finely-taunted polysilicon (low temperature polysilicon, LTP) or oxide made from indium, gallium and zinc (ijzo). And in future also by combining it.

The simplest and cheapest versions are TFTs made of amorfema silicon (A-C). Due to the very irregular crystal structure, you can only use A-C-TFT where there are no particular small pixels or final bit of switching speed.

The A-C-TFT is a transistor made of a hundred times polychristline silicone as high electron mobility as high electron mobility. Because their single -christian clusters are interrupted only by grain boundaries, electrons spread rapidly. As a result, the pixel transistors can be smaller and the supply lines can be narrower, the mild permeability of the panel increases, the need for energy for the backlight decreases. It is ideal for mobile devices. Disadvantage of LTPS: Technology is expensive because the unaccounted silicon in the loading carrier canal was first heated by laser and thus has to be converted into polycrystaline silicone.
