Abstract
A backlight driving circuit includes a backlight driving sub-circuit. The backlight driving sub-circuit includes at least one voltage receiving end; at least two switch sub-circuits and at least two driving ends. The voltage receiving end is connected to first electrodes of at least two light emitting elements. Second electrodes of the at least two light emitting elements are connected to first ends of the at least two switch sub-circuits, respectively. The control end of each switch sub-circuit receives a switch control signal. The second end of each switch sub-circuit is connected to a corresponding driving end. The first end and the second end of the switch sub-circuit are connected or disconnected under the control of the switch control signal.
