DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

A display device and a driving method thereof are provided to enhance a response speed of the device, without using a separate memory, thereby preventing image sticking due to delay of the response speed. A display panel has a pixel defined by a gate line(10) and a data line(20), and a common electrode(40) formed opposite to the pixel. A common voltage generator(120) generates a positive common voltage and a negative common voltage which is lower than the positive common voltage. A power supply unit(110) has a first power stage outputting a first voltage which is higher than the positive common voltage and a second power stage outputting a second voltage which is lower than the negative common voltage. A controller(100) controls the common voltage generator and the power supply unit.
