Backlight module structure

Abstract

The invention provides a backlight module structure which comprises a frame and a light guide plate. The frame is provided with a bearing part, one surface of the bearing part is used for bearing a display module, the bearing part is provided with a plurality of flanges and a plurality of grooves, and the flanges are misplaced with the grooves. The light guide plate is held in the frame and is correspondingly provided with a positioning groove and a positioning sheet, and the positioning groove and the positioning sheet of the light guide plate is clamped with the flanges and the grooves of the frame, thereby stably positioning the light guide plate in the frame, increasing attachment area of the display module and the frame, effectively improving structure intensity, and solving the problem of inconvenient assembly, difficult positioning, broken holes, and the like, possibly caused by thin form of the prior backlight module.

Description

technical field [0001] The invention relates to a backlight module structure, in particular to a backlight module structure which can not only fix the light guide plate stably on the frame, but also increase the attachment area between the display module and the frame, effectively improve the drop test, and enhance the structural strength. Background technique [0002] The thinner backlight module is the trend of the times, in order to achieve the thinner module, generally adopt the structure, such as Figure 1 to Figure 4 The structure of a known frame (Housing) 10 is shown, and as Figure 5 and Figure 6 The light guide plate 20 matched with the frame 10 is shown; the frame 10 has a bearing portion 11, and the bearing portion 11 includes a front side 11a and a back side 11b, wherein the front side 11a is used to carry a liquid crystal display module (not shown in the figure) Out), the bearing part 11 has a generally rectangular accommodation hole 111, the periphery of the...

AI Technical Summary

Problems solved by technology

[0008] In view of the lack of conventional technology, the purpose of the present invention is to propose a backlight module structure, which not only enables the light guide plate to be firmly fixed on the frame, but also increases the attachment area between the display module and the frame, effectively improves the drop test, and enhances the structural strength. It can solve the problems of inconvenient assembly, difficult positioning and broken holes that may occur after the traditional display module is thin.
