Abstract

The invention provides a unit pixel structure for liquid crystal displays. A liquid crystal display comprises an array substrate, a color film substrate, and liquid crystal; the array substrate and the color film substrate face each other; the liquid crystal is arranged between the array substrate and the color film substrate; the liquid crystal is in a UV vertical alignment mode; the array substrate comprises scan lines, data lines and pixel electrodes; the scan lines and the data lines intersect crisscross; the pixel electrodes are limited by the scan lines and the data lines intersecting; black lines occur to a pixel electrode area due to UV vertical alignment; the edge of the pixel electrodes is partially provided with a radial slit pattern protruding out. The unit pixel structure has the advantages that the edge black lines expand out of the pixel electrodes, force of the ITO fringe field upon liquid crystal molecules moves out, the dark lines are moved out of an aperture area, a Fine Slit structure enables the black lines to move out to be eliminated, load of resistance and capacitance of an array panel is not increased much, aperture ratio is not lowered, and light transmitting efficiency of UV vertical alignment displays is increased.

Description

technical field [0001] The invention relates to a liquid crystal display of UV light vertical alignment mode, in particular to its unit pixel structure. Background technique [0002] UV 2 A (Ultra Violet Vertical Alignment) technology is a VA (Vertical Alignment, vertical alignment) panel technology that uses ultraviolet light (UV=Ultra Violet) to align liquid crystals. Its name comes from the multiplication of ultraviolet UV and VA mode of liquid crystal panels. By importing UV 2 After A technology, the slits and protrusions currently used to control the alignment of liquid crystal molecules in VA mode liquid crystal panels can be omitted, so through UV 2 The aperture ratio, contrast ratio, and response speed of A-technology LCD panels can be improved, and the production process can be greatly reduced. [0003] UV 2 The key of technology A is to develop the polymer material used as the alignment film. The main chain of the polymer on the surface of the alignment film is...
