Abstract
Disclosed are an LCD device and a driving method thereof. The LCD device includes at least one source driving ICs configured to drive a plurality of data lines formed in a panel, a timing controller configured to generate a power control signal used to change a level of a driving voltage applied to the source driving ICs according to a pattern of an image output to the panel, and a driving voltage generator configured to generate a first driving voltage or a second driving voltage according to the power control signal to drive the source driving ICs. The first and second driving voltages have different levels.

A liquid crystal display (LCD) device comprising:
- at least one or more source driving ICs configured to drive a plurality of data lines formed in a panel;
- a timing controller configured to generate a power control signal, used to change a level of a driving voltage applied to the source driving ICs, according to a pattern of an image output to the panel;
- and
- a driving voltage generator configured to generate a first driving voltage or a second driving voltage according to the power control signal to drive the source driving ICs, the first and second driving voltages having different levels.
A method of driving a liquid crystal display (LCD) device, the method comprising:
- analyzing input video data to generate different power control signals according to a pattern of an image output to a panel;
- generating a first driving voltage or a second driving voltage according to the power control signals, the first and second driving voltages having different levels;
- and
- converting image data corresponding to the input video data into data voltages according to the first driving voltage or the second driving voltage to output the image data to the panel.
