Patent ID: 8638359

Claim:
A display apparatus comprising: a timing controller that receives a first image signal of a first perspective and a second image signal of a second perspective in synchronization with a first control signal during a three-dimensional (3D) mode and receives a two-dimensional (2D) image signal, in synchronization with a second control signal during a 2D mode; a data driver that converts the first image signal to a first data voltage and the second image signal to a second data voltage to alternately output the first and second data voltages in one frame unit during the 3D mode and converts the 2D image signal to a third data voltage to output the third data voltage in one frame unit during the 2D mode; a detector that determines whether the timing controller is operated in the 3D mode or the 2D mode based on the first and second control signals and outputs a first mode signal or a second mode signal to the timing controller according to a result of the determination; a display panel that alternately displays an image of the first image signal corresponding to the first data voltage and an image of the second image signal corresponding to the second data voltage in one frame unit during the 3D mode and displays a 2D image corresponding to the third data voltage during the 2D mode; a gate driver that generates a gate driving voltage as a gate si al and provides the gate driving voltage to the display panel; and a voltage generator that increases the gate driving voltage higher than a reference voltage in response to the first mode signal and decreases the increased gate driving voltage to the reference voltage in response to the second mode signal.
