Problems solved by technology

[0004] Based on the above, the conventional side-illuminated backlight module 100 needs to lock the frame 140 on the metal lampshade 110 by screws, so the assembly is more troublesome, and there will be problems with screw alignment, resulting in an increase in the defective rate
In addition, when rework (that is, reassembly) is required, it is necessary to take out the light guide plate 150 and loosen the screws first, so it will consume more time.

Abstract

The invention relates to a backlight module which comprises a strengthened adhesive tap, a light source assembly and a light guide plate. The strengthened adhesive tap is bent to form a shade, a supporting part extends out from the bottom of the shade, and the shade is provided with an opening; the light source assembly is attached to the shade and is arranged in the shade; and the light guide plate is provided with an incident surface, a bottom surface adjacent to the incident surface and an exit surface, a part of the bottom surface is opposite to the supporting part, and the incident surface is placed at the position of the opening. In the assembly of the backlight module, the backlight module can be directly attached to other members through the shade and can be assembled conveniently. In addition, when reworking is required, reworking can be carried out easily just by tearing off the strengthened adhesive tap without the locking of screws.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a backlight module for providing light sources for liquid crystal display panels. Background technique [0002] Since the liquid crystal display panel does not have self-luminous characteristics, in order to achieve the display effect, the backlight module needs to provide a display light source for the liquid crystal display panel. Backlight modules are divided into direct-lit backlight modules and side-illuminated backlight modules. figure 1 It is a schematic diagram of a known side-illuminated backlight module. see figure 1 , the conventional side-illuminated backlight module 100 includes a metal lampshade 110, a light emitting diode light source 120, a frame 140 for supporting a liquid crystal display panel, a light guide plate 150, a reflector 160 and a plurality of optical films 170 , wherein the LED light source 120 includes a printed circuit board 122 (printed ci...
