Problems solved by technology

Due to the symmetrical design of the alignment slit 34, the arrangement of the liquid crystal molecules in each pixel should be the same in theory, but in fact, in different pixels, the arrangement of the liquid crystal molecules at the intersection positions in the middle of the four alignment regions will be slightly different. Different, this phenomenon makes the display brightness of each pixel different when displaying the same grayscale image, which in turn leads to uneven display brightness of the liquid crystal display

Embodiment Construction

[0062] FIG. 2 is a schematic top view of a pixel structure of the present invention. Please refer to FIG. 2 , in this embodiment, each pixel structure 230 a includes an active device 234 and a pixel electrode 236 . The pixel electrode 236 is electrically connected to the active device 234 . In this embodiment, the pixel electrode 236 is electrically connected to the active device 234 through the contact window 238 , for example. The pixel electrode 236 is divided into a plurality of alignment regions 236a, and each alignment region 236a has a group of alignment slits 236b with the same alignment direction, and the alignment slits 236b adjacent to the alignment regions 236a have a symmetrical alignment direction, wherein Each group of alignment slits 236b includes a first alignment slit 236b1 and a second alignment slit 236b2, wherein the number of the first alignment slit 236b1 is the largest and the length is the same, and the alignment slit 236b of at least one of the align...

Abstract

The invention discloses a pixel structure and a liquid crystal display having the same, wherein the pixel structure comprises an active element and a pixel electrode. The pixel electrode is in electrical connection with the active element, and a pixel electric area is provided with a plurality of alignment regions. Each alignment region of the pixel electrode is provided with a group of alignment slits which are opposite in alignment direction; the groups of alignment slits include a plurality of first alignment slits which are the same in length and account for the largest number. At least one group of alignment slits also comprises at least one second alignment slit of a length larger than that of each first alignment slit. The designed slits in the pixel structure of the invention can effectively control the arrangement of liquid crystal molecules and improve the condition of inconsistent brightness of pixels displaying the same gray scale image. In addition, the slits in the pixel structure of the invention can be driven by the prior drive circuit and have a process which is the same as the prior process in manufacture, thereby not resulting in cost burden.

Description

technical field [0001] The invention relates to a pixel structure and a liquid crystal display, and in particular to a pixel structure and a liquid crystal display with good display quality. Background technique [0002] As the display specifications of liquid crystal displays continue to develop towards large sizes, the performance requirements of the market for liquid crystal displays are high contrast (High Contrast Ratio), fast response, and wide viewing angles. In order to overcome the viewing angle problem of large-size liquid crystal display panels, The wide viewing angle technology of the liquid crystal display panel must also continuously improve and break through. Among them, the multi-domain vertical alignment mode (MVA mode) liquid crystal display panel is currently a relatively common wide viewing angle technology, such as the multi-domain vertical alignment mode (Multi-domain vertical alignment, MVA) liquid crystal display panel, Polymer Stabilized Alignment (...
