Problems solved by technology

[0004] However, in order to realize the positioning of the LCD backlight module and the terminal equipment, it is necessary to set a connecting plate on the back panel and punch screw holes, and it is necessary to add positioning holes to ensure the stability of the assembly of the back panel and the plastic frame. In this way, the plastic frame is required to ensure the quality The wall thickness needs to be relatively thick, and it is difficult to achieve a narrow frame design, which affects the development trend of narrow frame and thinner backlight modules

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0023] see figure 1 , the preferred embodiment of the present invention provides a backplane and a backlight module having the backplane. The backplane is used to carry elements such as the light guide plate of the backlight module. The back panel 10 includes a bottom panel 11 and side panels 12 formed by bending edges of the bottom panel 11 . The connection between the side plate 12 and the bottom plate 11 is provided with several positioning pieces 13 at intervals, and the positioning pieces 13 are located on the same side of the bottom plate 11 as the side plate 12 and opposite to the extension direction of the side plate 12 .

[0024] In this embodiment, the backboard 10 is formed by cutting a metal plate. The bottom plate 11 is a rectangular plate body. The side panel...

Abstract

The invention provides a back plate and a backlight module with the back plate. The backlight module comprises a light guide plate and an optical film arranged on the light guide plate. The back plate comprises a bottom plate and a side plate which is formed by bending the edge of the bottom plate; a plurality of positioning sheets are arranged far away from the extending direction of the side plate at the place where the side plate and the bottom plate are connected; the positioning sheets and the side plate are positioned on the same side of the bottom plate and are arranged opposite to the extending direction of the side plate; the light guide plate is arranged on the bottom plate. The invention also discloses a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backplane, a backlight module, a backlight module and a display device. Background technique [0002] At present, liquid crystal display devices have been widely used in various electronic products as display components of electronic equipment. With the development of thinner and lighter electronic products, the frame of electronic equipment is designed to be narrower and narrower. The backlight module is an important part of the liquid crystal display device, and the frame of the backlight module is bound to become narrower and narrower. [0003] The backlight module in the prior art includes a backplane, a light guide plate arranged above the backplane, an optical film, and a plastic frame for fixing and supporting the light guide plate and the optical film (usually by setting a positioning hole on the backplane) To position the plastic frame), the display pan...
