Liquid crystal display module

Abstract

The invention discloses a liquid crystal display module, which comprises an outer frame, a liquid crystal display panel, a modular frame, an optical modulex and a foreign matter isolation belt, wherein the foreign matter isolation belt is used for preventing a foreign matter entering an effective display area of the liquid crystal display module, comprises a pasting part and a hairbrush-type partarranged on the pasting part, and is arranged in gaps between the outer frame and the liquid crystal display panel, between the modular frame and the liquid crystal display panel and / or between the modular frame and the optical modulex. The invention seals a passage for the foreign matter entering the effective display area between the liquid crystal display module and the optical modulex throughforeign matter isolation belt, thereby reducing occurrence of bad foreign matters.

Description

technical field [0001] The present invention relates to a liquid crystal display module, in particular to a liquid crystal display module capable of preventing foreign matter defects. Background technique [0002] The liquid crystal display module is a non-self-luminous display device, so it is necessary to set up a backlight module to provide a light source for the liquid crystal panel. According to the position of the light source in the backlight module, it can be divided into side-light liquid crystal display modules and direct-light liquid crystal display modules. . Since the edge-lit liquid crystal display module is more conducive to thinner and lighter design, the edge-lit liquid crystal display module is widely used in the industry to manufacture liquid crystal displays. [0003] figure 1 It is a side sectional view of an existing liquid crystal display module. Such as figure 1 As shown, the liquid crystal display module includes: a backplane 1 , a reflective fil...

Problems solved by technology

However, this treatment cannot remove foreign matter in the gap between the optical module and the mold frame, and may blow in a lot of foreign matter

Since the foreign matter after the wind blowing treatment is not in the effective display area above the optical module, such a liquid crystal display module will be judged as "good product" in product inspection, but this "good product" will not be detected during transportation and use. , after vibration or impact, the foreign matter in the gap will move to the effective area on the optical module, resulting in "foreign matter failure", which greatly affects the display quality of the display
