Abstract
The present invention discloses apparatus and techniques for modular backlighting control of a display. The display includes a number of strings of LEDs. The display is divided into several sections, and each section includes one or more strings of LEDs. A local controller is assigned to each section. The local controller receives feedback signals from the strings of LEDs in its sections and controls the drive voltages and drive currents of those strings. The local controllers communicate with each other and also with the main system controller.
