The Research And Design On The Peripheral Driving System Of AM-OLED Displays

Organic electroluminesence display is a fire-new flat panel display technology which was reputed having a fancy characteristic, because its luminescence is similar to LED, it is also called OLED (organic light emitting diode). OLED has been attracting much attention in recent years for its superior performance in the aspects of thin and light-weight, active emitting, wide visual angle, high brightness, fast video response time, low power dissipation, high efficiency, potential low cost, flexibleness, greenness, etc. The intrinsic characteristics of OLED give visual and form factor advantages over LCD, and OLED has been regards as one of the most ideal and potential next-generation display technologies with its excellent characteristic on information display and device fabrication. Although many achievements have been acquired in OLED structure material, production technology, drive methods, OLED technology is just at the beginning, OLED has given an equal chance for every company and country, and it is very important for our country to develop displaying technology of our own. The research direction of OLED is managing to improve the device lifetime, at the same time found a perfect production technological flow and the global standard production mode.It is still a arduous mission that we want to live up to a batch production of OLED displays in the future some years.Active matrix organic light emitting diode (AM-OLED) adopts a circuit structure based on matrix addressing, and its driving circuit includes pixel driving circuit and peripheral driving circuit. The pixel circuit can make OLED emit light. continuously, while the peripheral driving circuit is designed to provide correct input signals for AMOLED, for instance, provide the line-by-line scanning signals for row electrode of OLED matrix and the data...
