Abstract
Official abstract text for this publication.
A liquid crystal display (LCD) device is disclosed. The LCD device comprises a plurality of pixel units arranged in the form of a matrix. Each of the pixel units comprises: a scan line; a data line; a first storage capacitor; a liquid crystal capacitor; and a first TFT, having a source electrically connected to the data line, a gate electrically connected to the scan line, and a drain electrically connected to the first storage capacitor. Each of the pixel units further comprises a second TFT, having a gate, a source electrically connected to the drain of the first TFT, and a drain electrically connected to the liquid crystal capacitor. The gates of the second TFTs are electrically connected with each other to control the second TFTs to be turned on simultaneously so as to tilt the liquid crystal molecules. Because this shortens the time to wait for scanning of the gates is shortened and increases the time duration in which the backlight can emit light, the number of LEDs can be reduced to lower the cost.
