Problems solved by technology

[0003] However, it has been found through research that due to certain errors in the alignment process of the liquid crystal display, it is easy to cause the angle between the two domains in the pixel unit of the liquid crystal display to be different from the alignment direction.

Embodiment Construction

[0019] In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0020] First, the mechanism of the H Line Mura to be solved in this application will be explained.

[0021] There will be a certain deviation in the alignment direction of the liquid crystal display. Such as figure 1 As shown, theoretically, the alignment direction A of the liquid crystal display is required to be vertical at 90 degrees, and the included angle α between the align...

Abstract

The invention discloses a drive method and device and a liquid crystal displayer. The drive method comprises the steps that two sets of preset Gamma voltage of a display panel are obtained, the preset Gamma voltage comprises first Gamma voltage needed by first domain sub-pixels corresponding to different scales, and second Gamma voltage needed by second domain sub-pixels corresponding to the different scales; set gray scales of pixels are obtained, first Gamma voltage needed by the set gray scale is determined by the first Gamma voltage, and second Gamma voltage needed by the set gray scale is determined by the second Gamma voltage; the first Gamma voltage is exerted on the first domain sub-pixels of the pixels, and the second Gamma voltage is exerted on the second domain sub-pixels of the pixels so that the pixels can display the set gray scales. By means of the mode, the problem of H Line Mura can be avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving method, device and liquid crystal display. Background technique [0002] At present, in order to avoid the problem of easy occurrence of color shift under different viewing angles, liquid crystal displays are usually configured with a dual-domain (English: domain) structure. Each pixel of a dual-domain liquid crystal display includes two regions with different orientations of liquid crystals. Due to the self-compensation of the liquid crystal molecules in the liquid crystal display with a dual domain structure, the viewer will not see obvious color changes when viewing in different directions. [0003] However, it has been found through research that due to certain errors in the alignment process of the liquid crystal display, it is easy to cause the angle between the two domains in the pixel unit of the liquid crystal display to be different from the alignm...
