LED BACKLIGHT DRIVING CIRCUIT, LCD DEVICE, AND METHOD FOR DRIVING THE LED BACKLIGHT DRIVING CIRCUIT

摘要

A light emitting diode (LED) backlight driving circuit includes an LED light bar, a power supply that drives the LED light bar, and a control assembly that controls the LED light bar and the power supply. The control assembly is configured with a monitor that reduces brightness of the LED light bar when a display image of a liquid crystal (LC) panel is switched between a two-dimensional (2D) display mode of the LC panel and a three-dimensional (3D) display mode of the LC panel, and the brightness of the LED light bar goes normal after a preset delay time.
