Abstract
A driving device includes a control unit, a switch unit and a driver unit. The control unit is configured to generate a gray scale output and a synchronization signal. The switch unit is coupled to an LED array, and switches among different conduction states based on a switching output. The driver unit is coupled to the control unit, the switch unit and the LED array. The driver unit generates the switching output based on a clock signal and the synchronization signal, and generates drive outputs for receipt by the LED array based on the clock signal, the gray scale output and the synchronization signal, so as to drive the LED array to emit light.
