Problems solved by technology

However, the above design will result in larger edge and thickness dimensions of the overall frame of the backlight module, which is not conducive to the thinning of the backlight module and display device and the structural design of narrow frames.
In addition, the production of the plastic frame also requires the design of molds, mold opening, mold testing and other operations, which affects the development timeliness

Embodiment Construction

[0028] The relevant technical contents of the present invention will be clearly presented in the following detailed description of preferred embodiments with reference to the accompanying drawings. Before proceeding to detailed description, it should be noted that similar elements are denoted by the same reference numerals.

[0029] refer to figure 1 , is a preferred embodiment of the backlight module of the present invention, which includes a frame 2, a plurality of light-emitting elements 5 disposed in the frame 2, and an optical unit 7 supported on the frame 2 for emitting light. Wherein, the optical unit 7 can be selected as a light guide plate, a light guide film and / or a combination of multiple optical films according to requirements.

[0030] The frame 2 is formed by bending a bendable circuit board 3. The bendable circuit board 3 includes a central area 31, a side wall area 32 bent and extended from the periphery of the central area 31, and an outward extension from t...

Abstract

The invention relates to a backlight module and a display device. The backlight module comprises a frame, a plurality of light-emitting pieces arranged in the frame and an optical unit which is arranged on the frame in a bearing mode and used for emitting light. The frame is formed by bending a bendable circuit board, and the bendable circuit board comprises a central area and a side wall area integrally bent and extended from the periphery of the central area. A plurality of light-emitting parts are arranged in the central area of the bendable circuit board at intervals, and the optical unitis not in contact with the light-emitting parts. The frame is formed by bending the bendable circuit board, and a rubber frame is not needed, so that the frame can be bent into different sizes, and the structural design of thinning and narrow borders is facilitated. The display device comprises the backlight module.

Description

technical field [0001] The invention relates to a display device, in particular to a backlight module and a display device. Background technique [0002] The existing backlight module mainly installs a light guide plate in the frame, and sets a light source on the light incident side of the light guide plate, and sets a plurality of optical films on the light output side of the light guide plate, so as to utilize the total reflection of light generated by the light guide plate. The performance and the microstructure of the light-emitting surface make the light emitted by the light source uniformly dispersed after passing through the light guide plate, and then the light emitted from the light-emitting surface of the light guide plate is further diffused and brightened by the optical film, so as to provide the display panel with Backlight with uniform brightness. [0003] In the existing structure, a plastic frame is usually installed on the periphery of the optical film to ...
