Driving device of liquid crystal display device and driving method thereof

摘要

A driving device of a liquid crystal display device includes a timing controller for receiving image information and a control signal from a graphic processor through an interface unit; a gate driver integrated circuit for receiving the control signal from the timing controller and a gate on/off power from a DC/DC converter and for supplying a scan signal to a gate pad area in a periphery of a liquid crystal panel; a data driver integrated circuit for receiving the image information and the control signal and for supplying the image information to a data pad area in a periphery of the liquid crystal panel; a first gamma voltage generator for supplying a first gamma voltage to the data driver integrated circuit in a general driving mode; and a second gamma voltage generator for supplying gamma voltages to the data driver integrated circuit in a halftone gray driving mode.
