Description

Lateral electric field type liquid crystal display

The present invention relates to liquid crystal displays, and more particularly to electrode structures for lateral electric field type liquid crystal displays.

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 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.

Another way to solve this type of problem is to use an In-Plane Switching (IPS) technique to form two electrodes on the same substrate so that the electric field is almost parallel to the substrate. Compared with the twisted nematic liquid crystal display, the in-plane switching liquid crystal display has the advantages of better image quality and improved viewing angle.

In a conventional in-plane switching liquid crystal display, the two electrodes formed on the same substrate are generally parallel to each other, so that the threshold voltage for driving such an in-plane switching liquid crystal display is high, and the contrast of the display is also poor. How to form a better electrode structure, lower the threshold voltage and improve the contrast of the display is a very urgent requirement in the design and production of liquid crystal displays.
