Description

Transverse electric field type liquid crystal display with non-constant distance between two electrodes

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

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 take advantage of this property to control light transmittance to produce images. The twisted nematic liquid crystal display has good light transmittance due to the structure of the liquid crystal molecules and the light characteristics, 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, which prevents the display from displaying a normal image.

Another way to solve this type of problem is to use In-Plane Switching (IPS) technology to form two electrodes on the same substrate so that the electric field is almost parallel to the substrate. Compared with a 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 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. Summary of the invention

A plurality of first electrodes and at least one second electrode are formed on the first substrate for respectively serving as a pixel electrode and a common electrode of the liquid crystal display. According to the invention, the plurality of first electrodes and the at least one second electrode may be formed on the same layer or different layers on the substrate. There is a non-constant distance between each adjacent first electrode and second electrode. Preferably, the maximum distance between the first electrode and the second electrode is greater than three times the minimum distance.

The present invention provides several different electrode configurations such that there can be an inconsistent distance between the first electrode and the second electrode. In one structural example, each of the first electrodes includes a vertical array of V-shaped electrode segments that are oriented in the same direction as the data lines of the liquid crystal display. Each of the second electrodes is a strip electrode and also runs in the same direction as the data line. The opening direction of the V-shape is perpendicular to the direction of the data line.

In another structural example of the present invention, each of the first electrodes includes a vertical array of V-shaped electrode segments, and the V-shaped openings of the V-shaped electrode segments of each of the two adjacent first electrodes face each other, so each Two adjacent first electrodes form a mirrored configuration. In still another structural example of the present invention, each of the second electrodes also includes a vertical array of V-shaped electrode segments, and the V-shaped openings of the V-shaped electrode segments of each of the adjacent first and second electrodes face each other. Therefore, each adjacent first electrode and second electrode form a mirror configuration.

According to other examples of the present invention, the V-shaped electrode segments of each of the first and second electrodes described above may be replaced with sinusoidal electrodes. Moreover, the first electrode and the second electrode may be oriented at a 45 degree angle to the direction of the data line of the liquid crystal display rather than being parallel to each other.

In another structural example of the present invention, each of the first electrodes includes a column of electrode segments, wherein each of the electrode segments has a convex and concave portion. Each of the second electrodes is a strip electrode or has the same structure as the first electrode. The first electrode and the second electrode may be oriented parallel to each other or at a 45 degree angle to the direction of the data line of the liquid crystal display.

In another structural example of the present invention, the data line of the liquid crystal display is bent at an intermediate point to form a V-shaped data line, and the V-shaped opening faces the left side. Each of the first electrode and the second electrode each includes a column of V-shaped electrode segments, a column of electrode segments having convex and concave portions, a strip electrode, or a sinusoidal electrode. Moreover, each of the first electrode and the second electrode are also bent at an intermediate point so that their directions are the same as those of the liquid crystal display.

According to the above description, in some exemplary structures, each two adjacent electrodes may form a mirror configuration. According to the present invention, the two adjacent electrodes may also have some positional differences in the arrangement of positions. They do not form a mirror configuration. In addition, the first electrode and the second electrode may be oriented perpendicular to the data line of the liquid crystal display or formed at other angles, for example, 15 to 30 degrees.
