Description

Liquid crystal display with long strips on the electrodes

The present invention relates to liquid crystal displays, and more particularly to liquid crystal displays having improved light transmittance and high contrast.

One characteristic of liquid crystal molecules is that they have different optical directions or different refraction effects when they are arranged differently. Liquid crystal displays use this property to control light transmittance to produce images. Due to the structure of the liquid crystal molecules and the influence of the light characteristics, the twisted nematic liquid crystal display has a good light transmittance, but the viewing angle of the display is very narrow.

In order to solve the problem of light transmittance and viewing angle, the twist vertical alignment mode is used to increase the light transmittance and increase the viewing angle. Since the liquid crystal molecules are vertically aligned, when the liquid crystal molecules receive a lower voltage and view the display in a squint direction, there is a problem that the gray scale is reversed. This produces a color shift in the squint direction, making the display unable to visualize normal images.

There is a method for solving this problem by forming two or more liquid crystal molecule alignment blocks in the same pixel to form a multi-region vertical alignment liquid crystal display, thereby eliminating the problem of gray scale inversion and improving the viewing angle. In practice, there are three specific methods. In the first method, each pixel is divided into a plurality of display regions, and each of the display regions utilizes capacitive coupling to form different voltages, thereby producing a display effect of the arrangement of the multi-region liquid crystal molecules. In the second method, each pixel is divided into a plurality of display regions, and two thin film transistors are used to make each display region have a different voltage, thereby solving the gray scale inversion problem. In the third method, each pixel is divided into two or more display regions, and an electron blocking material is covered over a part of the electrodes of the display region, thereby producing a display effect of the arrangement of the multi-region liquid crystal molecules.

However, these methods of solving the gray scale inversion problem using the prior art require a complicated liquid crystal display process. In view of the above, the subject matter of the present invention is to provide a simple, The method of improving light transmittance and improving contrast enables the liquid crystal display to display an optimum image.
