摘要： A backlight system for use in an LCD display with a driver providing current sink control includes an LED array module, a current feedback circuit, and a current compensation circuit. The LED array module has N columns of LEDs and each LED column has M LEDs connected in serial, wherein the current feedback circuit includes N current feedback units and the current compensation circuit includes N current compensation units, both of the current feedback circuit and the current compensation circuit being electrically coupled to the LED array module. When the backlight system is in operation, a current passes through an LED column, a current feedback unit, and a current compensation unit to generate an output voltage that is used for comparison with a predetermined DC voltage, and the current is compensated based on the results of the comparison.
