Embodiment 1

[0035] The backlight module provided in this embodiment can be applied to but not limited to various liquid crystal display screens, and the liquid crystal display screen in this embodiment can be applied to various terminals that Various smart mobile terminals (such as various smart phones, IPADs, etc.), various TV sets, advertising display terminals or PC terminals, etc.

[0036] The backlight module provided in this embodiment includes a backlight module main body, wherein the backlight module main body includes: a frame body, which is located in the frame body and is arranged on one side of the frame body (it should be understood that it can be the left side, the right side of the frame body). Side, upper side, or any side of the lower side can be flexibly selected and set according to specific application product requirements; The optical module into which the light enters; the backlight module main body also includes a first end (for example, the right end) located above...

Embodiment 2

[0050] For ease of understanding, this embodiment provides a manufacturing method of the backlight module shown in the above embodiments, please refer to Figure 8 shown, which includes:

[0051] S801: After the main body of the backlight module is produced, attach one end of the edge-wrapping film to the second end of the light-shielding layer, and the other end is a free end.

[0052] In this embodiment, the edge-wrapping film can be a black adhesive film, and the black adhesive film can be a single-sided black adhesive film with a sticky side attached to the light-shielding layer. For a schematic diagram of its attachment to the light-shielding layer, please refer to Figure 5-1 and Figure 5-2 As shown, one end of the black glue film 55 is attached to the left end of the light-shielding layer 54, and the size of the area attached between the two can be flexibly set, and the other end is a free end.

[0053] In this step, the main body of the backlight module can be prepa...

Abstract

The invention discloses a liquid crystal display screen, a backlight module and a manufacturing method thereof. The obtained backlight module comprises a frame body, a light source assembly which is located in the frame body and arranged at one side of the frame body, an optical module which is arranged in the frame body and opposite to the light source assembly in position so that light from thelight source assembly can enter the optical module, and a shading layer, wherein the first end of the shading layer is located on the optical module, and the second end opposite to the first end extends towards the light source assembly so that the light source assembly can be covered. The backlight module also comprises an edge covering film which at least covers the second end of the shading layer, the side face of the side, provided with the light source assembly, of the frame body and at least one part of the outer side of the bottom face connected with the side face, wherein the edge covering film is made of a non-light-transmitting material; the stability of the shading layer, the frame body and the light source assembly structure located between the shading layer and the frame bodycan be enhanced through the edge covering film; meanwhile, the edge covering film can also play a shading role, the stability and reliability of the backlight module can be comprehensively improved, and the occurrence probability of light leakage is reduced.

Description

technical field [0001] The invention relates to the field of backlight technology, in particular to a liquid crystal display screen, a backlight module and a manufacturing method thereof. Background technique [0002] The backlight module is one of the key components of the liquid crystal display panel. Its function is to supply sufficient brightness and uniformly distributed light source so that it can display images normally. The so-called backlight is a light source located behind the liquid crystal display. Its luminous effect It will directly affect the visual effect of the liquid crystal display module. The liquid crystal itself does not emit light. It displays graphics or characters as a result of its modulation of light. [0003] The backlight module generally consists of an optical module for carrying the backlight, a reflector, a light guide plate, etc., and a frame for carrying the backlight and the optical module. In order to avoid light leakage and affect the d...
