FPGA-based Design Of OLED Drive

OLED displays have many advantages, because of its adaptability to environment, display well, thin and low-power it will be become the most potential display technology. With the development of low-temperature polysilicon thin-film transistor technology, the advantages of OLED display technology is more prominent. But because of the low life of OLED displays, therefore, increasing the life of OLED displays are problems to be solved.Generally, in order to increase the life of the OLED display start from the organic light-emitting materials. In this paper, we make a point of view of a driver circuit to increase OLED display. In this paper I demonstrated the relationship of OLED display life and the storage capacitor--the greater of storage capacitor, the lower of OLED life. First, Designed a method for reducing the storage capacitor circuit, through HSPICE simulation, verify the design of the circuit not only has the effect of general display drive circuit, but also reduce the storage capacitor, increase OLED life. And then, designed OLED driver display system based on FPGA, include sampling of analog data, converting, processing, data caching and TFT matrix driven, its proved the drive circuit is correct and feasible.
