A display and control system of airborne LCD monitor based on Zynq platform was designed. This system synthesized various functions，such as backlight， key handling， temperature acquisition， low temperature heating， serial communication， instrumental interface display， display driver， etc. It adopted the hardware and software co-design to partition these functions， and took full advantages of the ability of parallel data processing of FPGA in Zynq platform and the flexible and efficient embedded programming model of ARM. Finally， the experiment results demonstrated that the designed system could operate well and all the functions could satisfy the predesigned requirements， which implied the potential engineering value.
