Patent ID: 8531371

Claim:
A liquid crystal display, comprising: a first substrate and a second substrate facing each other; a liquid crystal layer disposed between the first substrate and the second substrate and comprising liquid crystal molecules; a gate line disposed on the first substrate, the gate line to transmit a gate signal; a first data line disposed on the first substrate, the first data line to transmit a data voltage, the data voltage being generated at a data driver; a first voltage line disposed on the first substrate, the first voltage line to alternately transmit a first voltage and a second voltage that is greater than the first voltage, the first voltage and the second voltage being generated at a voltage generator different from the data driver; a first switching element connected to the gate line and the first data line; a second switching element connected to the gate line and the first voltage line; a first pixel electrode connected to the first switching element; and a second pixel electrode connected to the second switching element, wherein the first pixel electrode and the second pixel electrode form a liquid crystal capacitor along with the liquid crystal layer, and at least one of the first voltage and the second voltage is a variable voltage based on an analysis of an input image signal.
