Abstract

The invention provides a backlight module. The backlight module comprises a back frame, an optical film material located in the back frame, square glue located on the surface of the back frame and a bonding layer located between the back frame and the square glue. The square glue comprises a four-section type frame and a connecting part between every two adjacent sections. The connecting parts arewider than the frame, and the area of the bonding layer corresponding to the frame is smaller than that of the bonding layer corresponding to the joining part, so the total square glue coating amountcan be reduced, the cost is reduced, the gluing adhesive force of the connecting part is improved, the problems of glue failure and degumming are reduced, the relative positions of the optical film material and the back frame are not changed, the display quality of the backlight module is improved, and the economic benefits are increased.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module. Background technique [0002] The advantages of narrow-frame mobile phone screens are very obvious. One is to increase the screen-to-body ratio, reduce the additional area of ​​the mobile phone, increase the operational sense of the touch screen of the smartphone, and reduce the body size. The horizontal width of the narrow-frame mobile phone is larger than that of ordinary frames The horizontal width of the mobile phone is narrower, which improves the visual effect and allows users to watch the mobile phone screen better. In addition to narrowing the frame of the liquid crystal display panel, the frame of the backlight module must be narrowed for a narrow-frame mobile phone screen, and the two are combined to realize a narrow-frame liquid crystal display device. [0003] The backlight module specifically includes the back frame, LED lamp, light gu...
