A liquid crystal display device and a method for driving the same are disclosed. The device includes a gamma voltage generation circuit for generating first to ith positive gamma reference voltages having different levels, and first to ith negative gamma reference voltages having different levels, and a plurality of data drive chips, each of the data drive chips converting digital data input thereto into a positive data voltage and a negative data voltage and supplying the positive data voltage and negative data voltage to a liquid crystal display panel, and adjusting a level of the positive data voltage based on a positive gamma reference voltage supplied thereto, among the first to ith positive gamma reference voltages, and adjusting a level of the negative data voltage based on a negative gamma reference voltage supplied thereto, among the first to ith negative gamma reference voltages.

Liquid crystal display device and method for driving the same

A method of driving and a liquid crystal display that are adaptive for preventing a motion blur phenomenon inserting a black data without reducing a data charging time are disclosed. In the liquid crystal display, a first gate line supplies a first scanning signal. A second gate line supplies a second scanning signal. A data line supplies a data signal. A common line supplies a common voltage. A first thin film transistor supplies the data signal in response to the first scanning signal. In a liquid crystal cell, a pixel electrode is connected to the first thin film transistor and a common electrode is connected to the common line. A second thin film transistor supplies the common voltage to the pixel electrode in response to the second scanning signal.

Method and apparatus for processing data of liquid crystal display

A circuit that drives a liquid crystal display device, includes an EEPROM having control data that over-drives and provides adaptive brightness intensification, the control data in the EEPROM is protected so as to secure reliability of the EEPROM. The circuit includes a master for over-driving and adaptive brightness intensification, a slave for providing control data to the master, a connector for connecting external writing equipment with terminals on the slave to write the control data into the slave, and an internal power supply of a liquid crystal module that applies an internal supply voltage to the slave. A write control terminal on the slave is grounded in a write mode, and connected to the internal power supply of the liquid crystal module in a liquid crystal module drive mode.
