LT7911D and LT9211 chips were selected as display bridge chips， which integrated power supply， data transmission， and audio-video signal transmission functions through Type-C interface. The debugging was easy，the process was mature， and it did not require a large area， which facilitated the miniaturization of the entire system. A micro image source driver system based on the STC MCU was implemented and the localization of display driver chips was achieved. At the same time， a fast adaptive Gamma correction algorithm was used to improve the display effect of micro image source and could make it better applied to the field of head mounted display.
