Embodiment Construction

[0039] Please refer to Figure 5, which shows a pixel array 500 according to an embodiment of the present invention. The pixel array 500 can be applied to various types of liquid crystal display (LCD) devices, such as vertically-aligned (VA) LCD or twisted-nematic (TN) LCD. The pixel array 500 includes a plurality of rectangular pixels, and each pixel is divided into two sub-pixels. Each pixel is further divided into multiple regions, and the liquid crystal molecules in these regions are aligned in different directions. In one embodiment, pixel 502 is divided into three sections of pixels 508 , 510 and 512 by slits 514 and 516 . The slit 514 extends from the midpoint on one side of the pixel 502 to a corner on the other side of the pixel 502 , and the slit 516 extends from the midpoint on one side of the pixel 502 to the other corner on the other side of the pixel 502 . Some pixels 508 and 510 are electrically connected, and some pixels 512 are not electrically connected to...

Abstract

The present invention provides a liquid crystal display having one or more pixels, each pixel comprising: a first pixel operated at a first threshold voltage; and a second sub pixel adjacent to the first pixel and operated at a second threshold voltage Voltage operation; wherein the first pixel is divided into two parts by the second pixel to form at least four areas of liquid crystal molecules, and the four areas emit light in different gray scales, so as to improve the viewing angle characteristics of the liquid crystal display.

Description

technical field [0001] The present invention relates to a liquid crystal display, and more particularly to a liquid crystal display with compensated pixel arrays. Background technique [0002] A liquid crystal display is a thin and flat display device, which includes a plurality of pixels arranged in an array in front of a light source or reflective source, and each pixel includes a layer of liquid crystal molecules between two electrodes. When a voltage is applied to the electrodes, an electrostatic force will be generated that causes the liquid crystal molecules to twist, and the twisting of the liquid crystal molecules can cause the light passing through the liquid crystal molecules to twist, thereby allowing (or not allowing) various angles of light to pass through the filter (filter). Therefore, an image is displayed by pixels located in columns and rows. [0003] figure 1 A known pixel array 100 is shown, each pixel 102 includes a first sub-pixel 104 and a second su...
