Display driving circuit of liquid crystal display for space

The invention discloses a display driving circuit of a liquid crystal display for space. The display driving circuit comprises an FPGA (Field Programmable Gate Array) controller, a video acquisition and conversion circuit, a serial communication interface conversion circuit, a memory and a video LVDS (Low Voltage Differential Signaling) driver, wherein both the video acquisition and conversion circuit and the serial communication interface conversion circuit are connected with an input end of the FPGA controller; the memory is connected with the FPGA controller; and a video signal is output to a display screen by the FPGA controller through the video LVDS driver. The display driving circuit of the liquid crystal display for space has an anti-irradiation function.
