Abstract: The invention discloses an LED display panel driving method and system. The method comprises the steps that an HDMI/DVI video signal is converted into an RGB signal; the RGB signal is divided into N independent code streams, and reordering is carried out; and direct current provided for an LED display module is periodically switched at least between first current I1 and second current I2. The system comprises an FPGA controller, a video signal decoder, a first external memory, a second external memory and the LED display module, wherein the video signal decoder, the first external memory, the second external memory and the LED display module are respectively connected with the FPGA controller, wherein the FPGA controller comprises N LED driving modules which are connected in parallel. According to the driving method and system, which are provided by the invention, the LED luminous efficacy can be improved, and LED linear dimming can be carried out.
