Problems solved by technology

Any of the above situations will cause the defect caused by the severe contact of the diaphragm 23 with other components 1 and 231—backlight unevenness (Backlight Mura, a phenomenon in which various traces are caused by uneven brightness of the display)
In addition, if the film 23 has scratches or other defects, the upper diffusion film 234 and the double-sided adhesive tape 11 must be manually scraped off the frame 24 in the process of backlight repair, so as to replace it. action, so not only time-consuming and labor-intensive, but also may damage the frame 24 and other components

Embodiment Construction

[0041] The aforementioned and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings.

[0042] refer to Figure 5 to Figure 7 , the preferred embodiment of the liquid crystal display backlight module of the present invention includes a frame 4 , an optical film set 5 , two cover plates 421 , and two locking devices 42 . Wherein, the optical film group 5 is a prism film 231 (see figure 2 ), a reflective film 232 (see figure 2 ) and a diffusion film 233 (see figure 2 ), and the frame 4 has a left surface 411 and a right surface 412.

[0043] In this embodiment, the frame 4 forms a pair of cover plates 421 respectively corresponding to the left and right surfaces 411, 412 during injection molding. The structures of the two cover plates 421 are symmetrical and one end of each cover plate 421 is A connecting portion 425 is connected to the...

Abstract

A frame assembly structure of a backlight module and a backlight module using the frame, the frame assembly structure includes a frame and two locking devices, the frame has a left surface and a right surface for at least one optical film A left lug and a right lug are placed correspondingly, and the detent devices are respectively used to releasably restrain each of the lugs on a corresponding surface, and maintain a predetermined tolerance with the corresponding surface. Each of the lugs is allowed to be displaced on the corresponding surface, and the backlight module includes the frame assembly structure, an optical film group and a light source, and the optical film group has a function respectively placed on the left surface and the right surface A left lug and a right lug, when the optical film group is heated and stretched laterally together with the lugs, the locking devices provide a movable distance for the lugs to expand outward. The invention can avoid uneven backlight, reduce backlight repair time, and improve liquid crystal display installation efficiency.

Description

【Technical field】 [0001] The invention relates to a frame assembly structure of a backlight module and a backlight module using the frame, in particular to a frame assembly structure used in the backlight module for setting an optical film and a backlight module of a liquid crystal display. 【Background technique】 [0002] In recent years, with the progress and development of the 3C industry, liquid crystal displays (Liquid Crystal Display, LCD for short) have been widely used in notebook computers, desktop computers, personal digital assistants (PDA, Personal Digital Assistant) and so on. [0003] A liquid crystal display includes a liquid crystal display panel (LCD panel) and a backlight module. Oxi de, indium tin oxide) film, alignment film, control circuit and other components. Generally speaking, the backlight module can be divided into two types: direct-lit and side-lit. Since the liquid crystal itself does not emit light, the backlight module must be used to supply su...
