Patent ID: 8217873

Claim:
A liquid crystal display (LCD) device for improving color washout effect, the LCD device comprising: a first data line; a first scan line; a second scan line being a next scan line of the first scan line; a third scan line being a next scan line of the second scan line; a pixel formed at an intersection of the first data line and the first scan line, the pixel comprising: a first sub-pixel comprising: a first liquid crystal capacitor having a first terminal and a second terminal electrically connected to a common voltage; a first storage capacitor having a first terminal and a second terminal electrically connected to the second scan line; and a first switch having a first terminal electrically connected to the first data line, a second terminal electrically connected to the first terminal of the first liquid crystal capacitor and the first terminal of the first storage capacitor, and a control terminal electrically connected to the first scan line; and a second sub-pixel comprising: a second liquid crystal capacitor having a first terminal and a second terminal electrically connected to the common voltage; a second storage capacitor having a first terminal and a second terminal directly electrically connected to the third scan line; and a second switch having a first terminal electrically connected to the first data line, a second terminal electrically connected to the first terminal of the second liquid crystal capacitor and the first terminal of the second storage capacitor, and a control terminal electrically connected to the first scan line; and a gate driving circuit, electrically connected to the first scan line, the second scan line and the third scan line, for generating driving signals of the first scan line, the second scan line and the third scan line in sequence; wherein the driving signals of two adjacent scan lines among the said scan lines have a first waveform and a second waveform, respectively, the first waveform switches among a first turn-off level, a turn-on level and a second turn-off level in sequence, and the second waveform switches among the second turn-off level, the turn-on level and the first turn-off level in sequence.
