Problems solved by technology

However, in some cases, users may want to share information with others through a notebook computer or personal computer, and a wide viewing angle is required at this time
Therefore, liquid crystal displays with a fixed viewing angle cannot continue to meet the needs of the market, and providing a multifunctional liquid crystal display with an adjustable viewing angle has become an important issue

Embodiment Construction

[0020] As shown in FIG. 1 , the present invention has a liquid crystal display 10 with an adjustable viewing angle, which has a liquid crystal display panel 11, which includes an upper substrate 12, a lower substrate 14, and a liquid crystal layer 16 arranged between the upper substrate 12 and the lower substrate 14. 1. The two polarizers 20 and 22 are respectively disposed on the outer surfaces of the upper substrate 12 and the lower substrate 14 . The liquid crystal layer 16 between the upper substrate 12 and the lower substrate 14 has a cell gap d, and the gap d represents the height of the liquid crystal layer 16 . The liquid crystal display panel 11 may optionally include two alignment films or alignment protrusions (not shown) disposed on inner surfaces of the upper substrate 12 and the lower substrate 14 . In the present invention, the liquid crystal display panel 11 is a multi-domain vertical alignment (MVA) liquid crystal display panel. The liquid crystal display 10 ...

Abstract

An LCD having switchable viewing angles comprises a display panel and a light source. The display panel comprises a first and a second substrates and a liquid crystal layer disposed between the first and the second substrates, wherein the liquid crystal layer comprises a phase retardation having a predetermined range of value more than wavelength of light produced form the light source so that the LCD displays at least a bright state and at least two dark states, or displays at least two bright states and at least a dark state. Therefore, the LCD provides switchable viewing angles.

Description

technical field [0001] The invention provides a liquid crystal display (LCD), especially a liquid crystal display with an adjustable viewing angle. Background technique [0002] At present, liquid crystal display is a representative of general flat display technology. Due to its thinness, low power consumption, no radiation and other excellent qualities, liquid crystal displays have become the mainstream of the market and are widely used in notebook computers, personal computers and other communication and information devices. Furthermore, in recent years, liquid crystal displays are gradually replacing traditional cathode ray tube (cathode ray tube, CRT) monitors and CRT televisions. [0003] As the size of the liquid crystal display increases, the viewing angle limit of the traditional twisted nematic (TN) liquid crystal display becomes more and more obvious. In order to improve the viewing angle limit and allow multiple users to observe undistorted images at various vie...
