Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] like figure 1 , image 3 and Figure 5 As shown, a backlight module 1 provided by the embodiment of the present invention includes an iron frame 11, and the iron frame 11 is composed of a bottom plate 111 and four side plates 112 enclosed and arranged on the bottom plate 111 to form a concave cavity 113, In actual production, in order to improve the processing efficiency, the side panels 112 and the bottom panel 111 are integrally formed by bending ultra-thin metal plates, so that the top surface is open, similar to a square drawer structure. The backlight module 1 also includes a light g...

Abstract

The invention is applicable to the technical field of display devices, and provides a backlight module and a display screen thereof. The backlight module comprises an iron frame, a light guide plate, a diffusion film and a bright enhancement film set, wherein the iron frame is combined by a bottom plate and four side plates which are enclosed on the bottom plate to form a cavity; the light guide plate, the diffusion film and the bright enhancement film set are laminated in sequence; the side plates are also provided with reinforcing plates in a bending manner; the inner side faces of the four side plates and the bottom plate are provided with reflecting layers; a light emitting circuit is arranged in a gap between the side face of the light guide plate and the side plates of the iron frame; the side face of the light guide plate is provided with prism stripes for reducing the brightness of the edge of the light guide plate. The display screen comprises the backlight module. According to the backlight module provided by the embodiment of the invention, the width of the frame of the backlight module is narrow and the strength is high, the integral strength of the product is guaranteed, and the requirements of the display screen on narrow-side and ultrathin development are met.

Description

technical field [0001] The invention belongs to the technical field of display devices, in particular to a backlight module and a display screen thereof. Background technique [0002] Liquid crystal display products are the most extensive and mainstream technical products at present. With the continuous development of mobile Internet technology, portable and ultra-thin devices have gradually become the development trend of mobile electronic equipment, which requires liquid crystal display modules (LCM) to become increasingly narrower and ultra-thin. The main components of the existing liquid crystal display backlight module are composed of a light source, a bracket, a reflection film, a light guide plate, a diffusion film, and a brightness enhancement film. The light source mainly uses LED-FPC (light-emitting diode flexible cable board), and uses plastic frames to fix and install various parts. However, the existing plastic frame is affected by the limit of injection moldin...
