LED DRIVING SYSTEM AND DISPLAY DEVICE USING THE SAME
摘要:
A light emitting diode (LED) driving system driving a LED array of a display device includes a converter circuit, a pulse width modulator (PWM) controller, a 2D parameter circuit, a 3D parameter circuit and a microcontroller. The 3D parameter circuit outputs 3D parameter control signals when the display device is in a 3D mode, and stops from generating the 3D parameter control signals when the display device is in a 2D mode. The PWM controller outputs PWM signals to control the converter circuit according to outputs of the 2D parameter circuit and the 3D parameter circuit.
