Design of Pmoled Display System Based on Pam

Abstract

-As the next generation of flat panel displays, OLED displays have a variety of outstanding features and advantages. At present, OLED display technology is a hotspot in the display technology research in the world. In addition, there are a large number of small and medium size OLED displays used in portable devices, and the manufacturing technology of large-size OLED display is maturing. An image display control system is designed for the PMOLED display. The system uses dedicated PMOLED display driver chip packaged by TAB and have advantages of easy driving and high reliability. Oxide TFT has advantages of better mobility, stability and uniformity, which is one of the most powerful competitors of active substrate technology. In this paper, a video display control system based on AMOLED display driver circuit of metal oxide TFT substrate is designed. The system uses TFT-LCD driver chip of COG package in place of AMOLED display dedicated driver chip, which has advantages of easy achievement and cheap and meets the needs of initial research and development of AMOLED display. The system takes DVI interface as the video signal transmission interface, and takes FPGA as a scan and data driver chip timing controller with reusable and flexible features. Video display control system has achieved a 7-inch 320x3x240 pixel AMOLED display real-time dynamic video display with 64 grayscale and 60Hz frame rate, and the display is good.
