Problems solved by technology

[0004] The embodiment of the present invention provides a backlight module, which is used to solve the backlight module with an in-plane hole structure in the prior art. Due to the addition of a light guide element and an extra lamp board inside the hole, assembly is difficult, and the ring guide needs to be adjusted. The light element and the ring light panel are fixed again, and the technical problem that the existing process is difficult to produce the ring light panel

Abstract

The invention provides a backlight module and a display device. The backlight module comprises a first region and a second region disposed in the first region. The first region is provided with a backplate. The back plate comprises a bottom plate and a side plate connected with the bottom plate. The bottom plate is a through hole in the second region. The side plate surrounds the second region. According to the backlight module, an annular flexible circuit board and a light guide component are arranged in the second region. A light source is disposed on the inside surface of the annular flexible circuit board. The annular flexible circuit board is fixedly connected with the side plate, so that the assembly process difficulty is reduced, the basic function of display can be achieved underthe action of the light guide component, and the fixing process of the light source can be simplified.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] With the development of full-screen technology, the backlight module of the display device has an in-plane hole structure, and mobile phone applications as a structure for the camera placement area have been launched to the market. Whether it is a through hole or a blind hole, the current in-plane hole There is no light source inside the hole of the structural backlight module to provide brightness, and the function of the hole is only the light entrance channel of the front camera. [0003] If light guide elements and additional light boards are added, although the panel area corresponding to the light guide hole can be made to realize the display function, the more parts are added, the easier it is to cause assembly difficulties. The light guide element and the lamp panel are fixed again, and it is difficu...
