摘要:
The present disclosure provides a light emitting diode (LED) backlight driving circuit, a liquid crystal display (LCD) device, and a driving circuit. The LED backlight driving circuit includes a timing control module, an LED lightbar, and a driver module coupled with an output end of the LED lightbar. The driver module includes at least one constant current driver chip driving the LED lightbar to display. The timing control module successively outputs a driving signal to the constant current driver chip. The driving signal includes data units which are arranged in sequence, and each data unit storing a current duty and a phase delay of one LED lightbar. The constant current driver chip directly reads data of a corresponding data unit and drives the LED lightbar to display.
