Problems solved by technology

The current panel structure is difficult to meet this demand, and when printing black borders up and down and adding light-shielding tape to the backlight module to reduce light leakage, due to size limitations, the tape is difficult to attach firmly and may also appear covered by the tape. The case of shiny surfaces

Embodiment Construction

[0020] In order to make the technical content disclosed in this application more detailed and complete, reference may be made to the drawings and the following various specific embodiments of the present invention, and the same symbols in the drawings represent the same or similar components. However, those skilled in the art should understand that the examples provided below are not intended to limit the scope of the present invention. In addition, the drawings are only for schematic illustration and are not drawn according to their original scale.

[0021] The specific implementation manners of various aspects of the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] As mentioned above, after the existing liquid crystal display panel is stored in a high-temperature and high-humidity environment, the optical film in the panel will warp to a large extent, resulting in moiré (mura), which is not conducive to image d...

Abstract

The invention provides a backlight module. The backlight module comprises an outer frame including a first step part and a second step part; a light guide plate arranged on the flat surface of the first step part; and a plurality of optical films stacked between the first step part and the second step part, wherein the top optical film of the plurality of optical films has an extension part at the periphery; the extension part is configured to a fold line structure to enhance the mechanical strength of the top optical film. According to the invention, the warpage problem of the film can be solved effectively by stacking the plurality of optical films between the first step part and the second step part of the outer frame of the backlight module and by forming the fold-line-like extension part at the periphery of at least the top optical film to enhance the mechanical strength of the top optical film.

Description

technical field [0001] The invention relates to a liquid crystal display device, in particular to a backlight module of the liquid crystal display device. Background technique [0002] In recent years, the flat panel display technology including the liquid crystal display technology has been greatly developed, and has gradually replaced the cathode ray tube (CRT, Cathode Ray Tube) display technology. For liquid crystal display devices, because the liquid crystal molecules themselves do not emit light, an additional light source is required. Generally, a liquid crystal module and a backlight module (Back Light Unit, BLU) connected to the liquid crystal module are usually provided. The light source is provided by the backlight source (such as LED point light source) and the light guide plate in the backlight module. [0003] In addition, driven by users' increasing requirements for portability, the design of liquid crystal display panels is increasingly meeting diversified sp...
