Embodiment Construction

[0070] The main principle of the optical compensation structure of the present invention and the liquid crystal display device with the optical compensation structure is to use a combined structure of at least one liquid crystal (C+) compensation film and an R-plate uniaxially stretched compensation film arranged vertically to replace The existing biaxial stretching process is difficult to control the Z-plate. In this way, the C-STN liquid crystal display device not only has a better viewing angle range and display quality due to the optical compensation effect, but also is easy to manufacture, low in cost, and easy to control quality.

[0071] Please refer to Fig. 4A to Fig. 4C, it is only when adding an R-plate uniaxial stretch compensation film (abbreviated as R-plate) on the C-STN type liquid crystal display, and when no liquid crystal (C+) compensation film is provided, its The comparison graph of the viewing angle range and the profile diagram of the horizontal and verti...

Abstract

The invention relates to a optical compensation structure and a LCD device provided with the optical compensation structure. In the invention, at least a LCD (C+) expiating film and a R-plate uni-axle extending expiating film are arranged between the C-STN-type LCD component of the LCD device. The optical compensation effect of Z-Axis direction and down visual angle is achieved by collocating the R-plate uni-axle extending expiating film and upright collocated LCD (C+) expiate film. The traditional used Z-plate extending expiating film which expiating the down visual angle of the C-STN-type LCD component with the difficulty of quality uncontrolled is replaced. The contrasting and color bias problem of the C-STN-type LCD device in the fastigiate angle is improved and the display quality is well.

Description

technical field [0001] The invention relates to an optical compensation structure and a liquid crystal display device with the optical compensation structure, especially to a color super twisted nematic liquid crystal display device, which provides a color super twisted nematic panel with a better downward viewing angle Compensating optical compensating structure. Background technique [0002] Liquid crystal displays (LCD for short) have been widely used in various electronic information devices, such as televisions, computers, mobile phones, personal digital assistants (PDAs), mobile audio-visual devices, and so on. The market expects that LCD colorization will become a future trend, and color super-twisted nematic (C-STN) liquid crystal display is a low-power and low-cost color panel product. At present, consumer electronic information products are constantly moving towards miniaturization, portable, and Under the design concept of civilian price, color super twisted nema...
