IGZO-TFT is also employed in the 14" 3,200x1,800 LCD of an ultrabook PC supplied by Fujitsu, also used in the Razer Blade 14" (Touchscreen Variant) Gaming Laptop and a 55" OLED TV supplied by LG Electronics. Sharp has started to release high pixel-density panels for notebook applications. Power consumption is improved by LCD idling stop technology, which is possible due to the high mobility and low off current of IGZO-TFT. In these, the aperture ratio of the LCD is improved by up to 20%. Sharp uses IGZO-TFT for smartphones, tablets, and 32" LCDs. In 2012, Sharp was first to start production of LCD panels incorporating IGZO-TFT. They have been licensed to Samsung Electronics (in 2011) and Sharp (in 2012). IGZO-TFT and its applications are patented by JST. It is currently used as the thin-film transistors for use in organic light-emitting diode (OLED) TV displays. As a result, IGZO-TFT can improve the speed, resolution and size of flat-panel displays. IGZO-TFT has 20–50 times the electron mobility of amorphous silicon, which has often been used in liquid-crystal displays (LCDs) and e-papers. IGZO-TFT was developed by Hideo Hosono's group at Tokyo Institute of Technology and Japan Science and Technology Agency (JST) in 2003 (crystalline IGZO-TFT) and in 2004 (amorphous IGZO-TFT). IGZO thin-film transistors (TFT) are used in the TFT backplane of flat-panel displays (FPDs).
