LIQUID CRYSTAL DISPLAY AND DRIVING METHOD THEREOF
First Claim
1. A Liquid Crystal Display (LCD) comprising:
- a display panel part comprising a pixel, the pixel comprising a plurality of sub-pixels;
a panel driver which drives the plurality of sub-pixels;
a backlight part which emits light of different colors to the display panel part;
a backlight driver which provides the light of the different colors corresponding to fields of a frame in sequence by sequentially driving the backlight part according to the fields; and
a controller which controls the panel driver to represent a color of the pixel of the frame by selectively using one or more of the sub-pixels of the pixel.

Abstract
A Liquid Crystal Display (LCD) and a driving method thereof are provided. The LCD includes: a display panel part including a pixel, the pixel including a plurality of sub-pixels; a panel driver which drives the sub-pixels; a backlight part which emits a light of different colors to the display panel part; a backlight driver which provides the light of the colors corresponding to fields of a frame in sequence by sequentially driving the backlight part according to the fields; and a controller which controls the panel driver to represent a color of the pixel of the frame by selectively using one or more of the sub-pixels of the pixel. Hence, the liquid crystal stress can be drastically improved without a loss of brightness.

10. A method of driving a Liquid Crystal Display (LCD), the method comprising:
-
providing light of different colors corresponding to fields of a frame in sequence according to the fields; when a current frame is input, representing a color of a pixel of the LCD by selectively using one or more of sub-pixels of the pixel; and when a next frame is input, representing a color of the pixel by selectively using one or more of the sub-pixels, wherein a sub-pixel combination used to represent a frame color of the current frame is different from a sub-pixel combination used to represent a frame color of the next frame. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 19)

18. A method of driving a display panel, the method comprising:
-
when a current frame is input, representing a color of a pixel of the display panel by selectively using one or more of sub-pixels of the pixel; and when a next frame is input, representing a color of the pixel by selectively using one or more of the sub-pixels, wherein a sub-pixel combination used to represent a frame color of the current frame is different from a sub-pixel combination used to represent a frame color of the next frame, and the sub-pixels provide light of different colors corresponding to fields of each frame in sequence according to the fields. - View Dependent Claims (20)
