Zusammenfassung:The invention discloses a liquid crystal panel TCON module based on an FPGA, which comprises the FPGA, a GAMMAR voltage generator and a power supply module, and is characterized in that the FPGA converts an externally input parallel digital video signal into an Mini-LVDS serial digital video signal according to a configuration parameter, a time sequence control signal of the gate driving circuit and a time sequence control signal of the source driving circuit are generated according to the time sequence of the parallel digital video signals, and then the Mini-LVDS serial digital video signals, the time sequence control signal of the gate driving circuit and the time sequence control signal of the source driving circuit are output to a liquid crystal panel; and the GAMMAR voltage generator outputs a Vcom voltage, a VTT voltage, and a GAMMAR voltage according to a configuration command. According to the resolution ratio of the liquid crystal panel, the front blanking area, the rear blanking area, the row pixel
