Embodiment Construction

[0019] Such as Figure 2-3 As shown, in a preferred embodiment of the present invention, the backplane module includes a backplane 100 and a backlight assembly 200 fixed in the backplane 100 through a positioning structure. The positioning structure includes a concave for fixing the backlight assembly 200 The positioning part 300 of the part 301 and the protrusion part 400 provided on the back plate 100, the backlight assembly 200 is fixed in the back plate 100 through the recessed part 301 of the positioning part 300 and the convex part 400 of the back plate 100. The positioning part 300 exists as an intermediate part, and its function is to fix the backlight assembly 200 in the backplane 100. The raised part 400 is provided on the backplane 100, and the concave part 301 is provided on the positioning part 300 to avoid the positioning part. 300 is exposed on the back plate, resulting in the occurrence of situations that affect the appearance of the product.

Abstract

A backlight module comprises a rear plate (10), and a backlight assembly (200) fixed in the rear plate (10) by a positioning structure. The positioning structure comprises a positioning member (300) used for fixing the backlight assembly (200) and provided with a concave portion (301), and comprises a convex portion (400) disposed on the rear plate (10). The backlight assembly (200) is fixed in the rear plate (10) by using a concave-convex match between the concave portion (301) of the positioning member (300) and the convex portion (400) on the rear plate (10). By means of the backlight module, the problem is solved that the product appearance is affected due to exposure of a convex point of a positioning member.

Description

technical field [0001] The present invention relates to the field of display devices, more specifically, to a backlight module. Background technique [0002] The positioning method of the light guide plate and the optical film 1 of the existing backlight module is as follows: the four corners of the back plate 3 are fixed by positioning pieces 2 . This fixing method can save the cutting cost of the positioning cutout, thereby reducing the cost of the backlight module. The specific structure is as follows: protruding points 4 are provided on the positioning member 2 , and positioning holes matching the protruding points 4 are provided on the back plate 3 . In order to prevent the positioning part 2 from absorbing light and reducing the optical efficiency, the positioning part 2 is generally made of white material. After forming the complete TV set, due to the addition of the back cover of the complete TV set, the white positioning parts exposed on the back plate 3 are cover...
