Patent ID: 8736540

Claim:
A liquid crystal display comprising: a gate-off voltage generator including a temperature compensation unit which comprises a constant voltage output device and which outputs a gate-off voltage having a level which varies based on a change in ambient temperature; a clock generator receiving a gate-on voltage and the gate-off voltage and which outputs a first clock signal and a second clock signal; a gate driver which receives the first clock signal and the second clock signal and outputs gate signals; and a plurality of pixels which turn on or off based on the gate signals, wherein the constant voltage output device outputs a temperature variable voltage having a value based on a voltage difference between a reference terminal of the constant voltage output device and an input terminal of the constant voltage output device, a voltage difference between the reference terminal and the input terminal of the constant voltage output device varies based on the change in the ambient temperature, and the constant voltage output device comprises a Zener diode having a Zener breakdown voltage which is proportional to the change in the ambient temperature.
