Liquid crystal display panel, liquid crystal display device using the same, and method for controlling liquid crystal molecules

Abstract

The invention discloses a liquid crystal display panel, a liquid crystal display device using the liquid crystal display panel and a method for controlling liquid crystal molecules. The liquid crystal display panel includes a first substrate, a second substrate and a plurality of liquid crystal molecules. The first substrate has a common electrode, the second substrate has a first pixel electrode and a second pixel electrode, and the first pixel electrode and the second pixel electrode are separated by a slit with a specific width. The liquid crystal molecules are vertically aligned above the first pixel electrode, the second pixel electrode and the slit. When a first voltage and a second voltage are supplied to the first and second pixel electrodes respectively, so that there is a first voltage difference and a second voltage difference between the first pixel electrode and the second pixel electrode and the common electrode, then the first pixel electrode and the second pixel electrode have a first voltage difference and a second voltage difference respectively. A liquid crystal molecule falls toward the first pixel electrode. Using slits in a specific width range, the liquid crystal molecules corresponding to pixel electrodes that generate different voltage differences are dumped in the same direction, reducing the area occupied by the slits and bumps, and improving the brightness and contrast of the liquid crystal display device.

Description

technical field [0001] The present invention relates to a liquid crystal display panel, a liquid crystal display device using the same and a method for controlling liquid crystal molecules, and in particular to a liquid crystal display panel using multi-domain vertical alignment (MVA) technology And a liquid crystal display device using the same and a method for controlling liquid crystal molecules. Background technique [0002] The multi-domain vertical alignment technology traditionally proposed to increase the viewing angle of liquid crystal display devices, in order to provide a wider range of viewing angles and solve the problem of color shift (color shift), the pixel electrodes in a single pixel are divided into different bias voltages. two pixel electrodes. The liquid crystal molecules have different inclination angles by different bias voltages, so that the brightness performance under different viewing angles is relatively uniform. Please refer to Figure 1A and ...

Problems solved by technology

[0003] However, the pixel electrodes of the traditional structure need to use bumps and slits to achieve the purpose of alignment, but these structures will block light and produce dark lines when they are bright.

When the bump is in the dark state, it will push down the liquid crystal and cause light leakage, resulting in a decrease in contrast
