Abstract

The invention discloses a backlight module. The backlight module includes a light emitting module, a support frame, a diffusion plate and a light guide. The light emitting module is arranged on a substrate and emits light. The support frame has a first support part, a diagonal part, a bearing part and a second support part connected in sequence. The first support part is adjacent to the light emitting module. The diffusion plate bears against the bearing part to receive light, and the area where the diffusion plate bears against the bearing part is formed as a bearing area. The light guide isprovided at least in the diagonal part, or at least in the bearing part, so that the light is transmitted to the bearing area. Therefore, the backlight module can improve the dark bands on the edge ofthe display surface of a display.

Description

technical field [0001] The invention relates to the technical field of a display, in particular, the invention relates to a backlight module capable of improving the problem of dark bands at the edge of a display surface of a display. Background technique [0002] With the continuous improvement of requirements for specifications such as resolution and narrow bezel, the optical configuration in the display device is also tested. [0003] Traditionally, the backlight modules of display devices can be roughly divided into two types: edge-lit and direct-lit. Among them, the direct-lit backlight modules mostly form a platform around the periphery with mechanical components, so that the platform can be used to carry the diffuser plate. , Optical films and display panels and other components. A reflective sheet is usually placed on the wall of this mechanical component to reflect light to the diffuser plate and avoid possible color lines or surface unevenness (MURA). However, due...
