The Research And Implementation Of Large Size High Resolution AMOLED Driver Control Circuit Based On FPGA

The organic light emitting display technology is one of the OEL displaytechnology, it is a different technology from the conventional display, and it does notrequire a backlight, but it relies on the carrier in the organic semiconductor material tocomposite in the organic material to be lighted in appropriate driving volotage.Therefore, OLED can achieve ultra-light, thin display. Besides this point, if you selectthe flexible plastic substrate as backplane materials, OLED can also achieve bendabledisplay, which is unmatched by traditional display technologies. Therefore, theorganic light emitting display is considered as the most potential for development of anew generation of fantastic display technology by the industry.The organic light emitting display developed rapidly in the past ten years, andpeople has made great achievements. More and more global display manufacturersand research institutions have invested in research and development, which greatlypromote the industrialization process of the OLED. However what has reached thelevel of the market is mainly in the small size, such as smart phones panel. Large-sizeOLED product market has not yet started, then this article self-designed the highresolution OLED drive control circuit, and on this basis, this article designed andimplemented the Shutter3D display technology.The article introduced the background knowledge of the technology,light-emitting principle, drive technology, and the implementation of colorizationmethod, and the characteristics of organic light emitting display, development historyand research status, described the feature of AMOLED panels, driver chips, and thefield programmable gate arrays selected in the development platform, designed theperipheral drive control circuit of active matrix organic light-emitting display(AMOLED), and completed the design of the entire drive control system using FPGA. and designed shutter3D display on this platform, realized3D display on AMOLEDscreen. Due to the difference of the decay time of the three primary color pixel, thesystem designed the RGB primary color pixels independent gamma correctionfunction module,which can improve the deviation from the gamma curve that causedby the difference of light emitting efficiency of the light emitting cells, which canimprove the uniformity of the AMOLED display. The design and development of thedrive control platform has very important significance in the research anddevelopment of the subsequent large-size organic light-emitting display technology...
