Patent ID: 8692752

Claim:
A vertical alignment liquid crystal display (VA-LCD) device, comprising: a display panel comprising a plurality of pixels, a plurality of data lines, and a plurality of scan lines intersecting the plurality of data lines, the plurality of scan lines and the plurality of data lines defining the plurality of pixels, a first pixel of the plurality of pixels comprising a first thin film transistor (TFT), a second TFT, and a liquid crystal capacitor having a pixel electrode and a common electrode, the first TFT and the second TFT being directly connected to the same liquid crystal capacitor, wherein in the first pixel, the common electrode being electrically connected to a source of the second TFT, a drain of the second TFT being electrically connected to the pixel electrode directly, a source of the first TFT being electrically connected to the first data line, a drain of the first TFT being electrically connected to the pixel electrode directly, a gate of the first TFT and a gate of the second TFT being electrically connected to the two scan lines adjacent to the pixel, respectively, and a switch-on resistance of the second TFT is greater than that of the first TFT, wherein, in a display frame time of the VA-LCD, the common electrode is applied with a common voltage, and the pixel electrode is applied with a first gray voltage and a second gray voltage such that the liquid crystal capacitor maintains the first gray voltage and the second gray voltage in succession, the first gray voltage being different from the second gray voltage, the first gray voltage being applied to the pixel electrode through the plurality of data lines and the first TFT, and the second gray voltage being applied to the pixel electrode through the common electrode and the second TFT.
