At present, the LCD industry is maturing. The panel enterprises continue to improve competitiveness of their products, high resolution, high color gamut, narrow bezel and high contrast ratio and so on. This paper expounds how to improve contrast ratio with the polyimide orientation material. Laboratory research and production line test has been done. By comparing the Advanced Super Dimension Switch (ADS) mode liquid crystal panel with the different orientation material, it concluded that the higher the orientation materials, the higher the contrast ratio to get the panel was. With high force orientation layer, it can have the better arrangement of the liquid crystal molecules. For normal dark pattern FFS display, the lower pre-tile angle of the liquid crystal molecules, the better LCD darkness and contrast ratio will be improved. [ABSTRACT FROM AUTHOR]
