Prototype Organic TFT Color LCD
The National Institute of Advanced Industrial Science and Technology (AIST) and Hitachi have jointly developed an organic thin-film transistor (TFT) color LCD prototype which uses organic TFTs as a driving switch. The 1.4-inch prototype has a resolution of 80×80 pixels, each of which measures 318×106 microns. The TFT is 50 microns in width and 5 microns in length. AIST expects that the organic TFT technologies will pave the way for the development of next-generation displays at lower costs.
The development of two key technologies has resulted in the successful prototyping of the organic TFT LCD. The joint team has developed a protective film technology to control deterioration in the performance of organic TFTs during the process of manufacturing the LCDs. The group has also developed a technology to reduce by nearly 80% resistance, which is created in the interface between an organic semiconductor and a metal electrode, by optimizing the shape of the electrode.
