Patent ID: 8217871

Claim:
A touch-controlled liquid crystal display comprising: a liquid crystal display panel comprising a first substrate, a second substrate and a liquid crystal layer disposed between the first substrate and the second substrate; and a touch panel disposed on a side of the second substrate facing away from the liquid crystal layer, the touch panel comprising: a plurality of first electrodes, the first electrodes being parallel to each other; a plate shaped second electrodes facing the first electrodes; a plurality of spacers disposed between the first electrodes and the second electrode so as to separate the first electrodes and the second electrode; a plurality of first control switch pairs; two second control switch pairs; a first demultiplexer; a second demultiplexer; a first power supply; and a second power supply, wherein the first power supply and the second power supply are respectively configured for outputting a voltage, the first electrodes are electrically coupled to the first power supply and the second power supply respectively through the first control switches and the second control switches, the outputs of the first demultiplexer are electrically coupled to the first control switches, a first scanning signal is inputted to the inputs of the first demultiplexer so that a corresponding first control signal is outputted from the outputs of the first demultiplexer so as to sequentially close the first control switch pairs, the outputs of the second demultiplexer are electrically coupled to the second control switches, and a second scanning signal is inputted to the inputs of the second demultiplexer so that a corresponding second control signal is outputted from the outputs of the second demultiplexer so as to sequentially close the second control switch pairs.
