Abstract

A light-emitting diode (LED) control system includes a LED array composed of a plurality of LED channels each being composed of a plurality of LEDs; a plurality of LED drivers connected in sequence each being configured to drive a corresponding LED channel, the LED channels being controlled in sequence by the LED drivers; and a LED controller that sends brightness data to the LED drivers, which in turn control brightness of the LEDs. After brightness data input has been transferred to an associated LED driver, the brightness data input is then replaced with status data returned by the associated LED driver, and the replaced status data is finally read by the LED controller via other LED drivers.
