Abstract
A drive method and system for an LED display panel. The method comprises: converting an HDMI/DVI video signal into an RGB signal; dividing the RGB signal into N independent code streams and re-ranking same; and periodically switching a direct current provided to an LED display module () at least between a first current Iand a second current I. The system comprises an FPGA controller (), and a video signal decoder (), a first external memory (), a second external memory () and an LED display module () which are respectively connected to the FPGA controller (). The FPGA controller () comprises N LED drive modules (-N) which are connected in parallel. The drive method and system can enhance the luminous efficacy of an LED, and can also conduct linear dimming on the LED.
