Abstract:
An LED backlight driving circuit includes a first and a second LED strings; a first and a second capacitors; a boosted circuit having an input connected to a power source and an output connected to the first and second capacitors and the first and second LED strings; an LED controller electrically connected to the boosted circuit so as to control, in a first period of an operation cycle, the boosted circuit to supply power to the first branch and to charge the first capacitor and also to supply power to the second branch and to charge the second capacitor; and in a second period, LED controllers controls the boosted circuit to cut off the first and second branches to make the first and second capacitors discharge to the first and second branches, respectively. Also provided is a liquid crystal display that includes the LED backlight driving circuit.

Claim (Index 1):
A light-emitting diode (LED) backlight driving circuit, comprising:\n a first LED string, located on a first branch circuit, and comprising a number of LED lights, the first LED string having a first terminal and an opposite terminal connected to ground; a second LED string, located on a second branch circuit different from the first branch circuit, and comprising a number of LED lights, the second LED string having a first terminal and an opposite second terminal connected to ground; a first capacitor, having a first terminal connected electrically with the first terminal of the first LED string and an opposite second terminal that is directly connected to ground; a second capacitor, having a first terminal connected electrically to the first terminal of the second LED string, and an opposite second terminal that is directly connected to ground; a boosted circuit, having an input terminal electrically connected to the power source for receiving power therefrom, and an output terminal electrically connected to the first terminal of the first capacitor, the first terminal of the second capacitor, the first terminal of the first LED string, and the first terminal of the second LED string; and an LED controller, connected electrically to the boosted circuit, wherein in a first period of an operation cycle, the LED controller controls the boosted circuit to supply power to the first branch circuit and to charge the first capacitor and also to supply power to the second branch circuit and to charge the second capacitor; and in a second period of the operation cycle, the LED controller controls the boosted circuit to cut off the supply of the power from the boosted circuit to the first branch circuit and the first capacitor so that the first capacitor discharges power that is fed through the first branch circuit, and the LED controller also controls the boosted circuit to cut off the supply of the power from the boosted circuit to the second branch circuit and the second capacitor so that the second capacitor discharges power that is fed through to the second branch circuit.
