Liquid crystal module and display device

Abstract

The invention relates to a liquid crystal module and a display device. The liquid crystal module comprises a liquid crystal glass and a light guide plate arranged on the side of the back surface of the liquid crystal glass; a polarizer and an optical film are arranged between the liquid crystal glass and the light guide plate, and a transparent air bag is arranged between the polarizer and the optical film. The display device comprises the liquid crystal module. According to the liquid crystal module and the display device, by arranging the transparent air bag is mounted in the gap between the liquid crystal glass and the light guide plate, the liquid crystal glass and the light guide plate can maintain a certain gap under the action of air pressure to avoid contact scratching of the liquid crystal glass and the light guide plate; meanwhile, the transparent air bag is airtight, so that foreign objects can be prevented from entering between the liquid crystal glass and the light guide plate, further the technical problem that a large-size liquid crystal module is prone to scratching and foreign object entrainment can be solved.

Description

technical field [0001] The invention relates to a pointing device which uses a static method to display variable information, in particular to a liquid crystal module and a display device. Background technique [0002] With the continuous innovation of display technology, displays are developing rapidly towards thinner body, narrower edge, and lighter weight. The current flat panel displays basically include liquid crystal modules. [0003] The internal structure of a conventional liquid crystal module is as follows: figure 1 As shown, it includes a liquid crystal glass 1', a light guide plate 2', a frame 3' covering the front of the liquid crystal glass 1', and a back plate 4' arranged on the back of the light guide plate 2', and the frame 3' is connected to the back plate 4' , to limit or fix the liquid crystal glass 1' and the light guide plate 2'. Usually, a polarizer 5' is attached to the lower surface of the liquid crystal glass 1', and an optical film 6' is attache...

AI Technical Summary

Problems solved by technology

[0004] When the size of the liquid crystal module is large, the liquid crystal glass 1' is likely to be bent and deformed under gravity or other pressures. At this time, the center of the polarizer 5' is likely to be in contact with the optical film 6' above the light guide plate 2' due to bending. , if the liquid crystal module vibrates, the two will continue to rub and cause scratches; at the same time, the gap between the polarizer 5' and the optical film 6' is easy to attract foreign matter, which affects the product quality of the liquid crystal module and causes poor vision
