摘要： A liquid crystal display includes a gate driver including stages, and a clock generator which receives a clock generation control signal, generates a clock signal and a clock bar signal based on one or more of the clock generation control signal, a gate-on voltage and a gate-off voltage, and outputs the clock signal and the clock bar signal to the gate driver. The clock generator includes an overcurrent protector unit which intercepts at least one of the clock signal and the clock bar signal when a voltage level of at least one of the gate-on voltage and the gate-off voltage is greater than a reference level.

摘要： A driving apparatus for a liquid crystal display, which includes a first pixel, a second pixel and a third pixel that display different colors, includes: an image signal compensation unit that compensates input image signals corresponding to the first pixel, the second pixel, and the third pixel to generate compensated input image signals; and a data driver that supplies data voltages to the first pixel, the second pixel and the third pixel based on the compensated input image signals. The image signal compensation unit shifts a value of the input image signal corresponding to the first pixel by a first value with respect to a common voltage, shifts a value of the input image signal corresponding to the second pixel by a second value with respect to the common voltage, and shifts a value of the input image signal corresponding to the third pixel by a third value with respect to the common voltage.
