The first data line is coupled to the first sub-electrode sub-region and covered by the first pixel electrode. The second data line is coupled to the first main electrode sub-region and covered by the second pixel electrode. The third data line is coupled to the second main electrode sub-region and covered by the second pixel electrode. The gate line is coupled to the first pixel electrode and the second pixel electrode.

Description

technical field [0001] The present invention relates to a liquid crystal display; in particular, to a design method of a wide viewing angle liquid crystal panel display using a multi-domain vertical alignment technology (Multi-domain Vertical Alignment, MVA). Background technique [0002] Liquid crystal displays (LCDs) have many advantages, such as small size, light weight, low power consumption, and the like. Therefore, LCDs have been widely used in electronic products such as portable computers and mobile phones, that is, LCDs have gradually replaced traditional cold cathode ray tubes (CRTs) and become the mainstream of displays. However, the biggest disadvantage of traditional LCD is its narrow viewing angle. The prior art has proposed many methods for improving the viewing angle characteristics of LCD; At the stage, two data signals of different sizes are provided to be transmitted to each electrode sub-area through the data line, such as figure 1 shown.

However, this move will reduce the opening ratio

Since the aperture ratio refers to the light transmittance ratio, that is, the effective area through which each pixel can transmit light is divided by the total area of ​​the pixel, so a smaller aperture ratio will cause the overall picture to become darker

[0006] In addition, vertical crosstalk (crosstalk) is another important factor affecting the image quality of LCDs, that is, the capacitive coupling effect generated by the data lines on the pixel electrodes, which leads to image distortion of LCDs.
