The application discloses a backlight module, an electronic device and a mounting method of the backlight module. The backlight module comprises a back frame, a connector and a light source, a flexible circuit board, a light guide plate and a dodging film layer arranged on the bottom plate, wherein the back frame comprises a bottom plate and a side wall, the side wall is bent relative to the bottom plate, and a hollowed region is arranged on the bottom plate; the connector is arranged in the hollowed region to cover the hollowed region; and the light guide plate comprises an incident face andan emitting face, the light source is arranged on the side of the incident face, and the dodging film layer is arranged on the emitting face; and the flexible circuit board is arranged on the side, opposite to the emitting face, of the light source, and is electrically connected to the light source. Therefore, the backlight module can be assembled from the front face (the emitting direction of thebacklight module) and the bottom face (the direction opposite to the emitting direction) of the back frame according to actual conditions when other components of the backlight module are assembled to combine front and back assembling, so that the backlight module is assembled conveniently.
Description
technical field [0001] The present application relates to the field of backlights of electronic devices, in particular to a backlight module, an electronic device and a method for installing the backlight module. Background technique [0002] At present, with the development of science and technology, electronic devices such as smart phones have gradually become necessities in people's lives. [0003] The backlight module is an important part of an electronic device. At present, the backlight module of a portable electronic device such as a smart phone usually consists of a back frame, or an iron frame, to form a housing space, and then other optical components of the backlight module are assembled into the in this accommodation space. However, the back frame of the prior art is usually a fixed integral structure, and the optical components such as the light source, diffusion film, and light guide plate of the backlight module have different shapes and sizes, and need to be...
