The application discloses a backlight module, an electronic device and an installing method of the backlight module. The backlight module comprises an upper back frame and a lower back frame, a lightsource and a flexible circuit board, a light guide plate and a dodging film layer; the upper back frame and the lower back frame are detachably connected to each other, and a holding space is formed between the upper back frame and the lower back frame; the light source and the flexible circuit board are arranged in the holding space, the light guide plate and the dodging film layer are arranged on the lower back frame, wherein the flexible circuit board and the dodging film layer are arranged at two opposite sides of the light source, the flexible circuit board is arranged between the light source and the lower back frame, and the flexible circuit board is electrically connected with the light source; the light guide plate comprises an in-light face and an out-light face; the light sourceis arranged at one side of the in-light face, and the dodging film layer is arranged on the out-light face; the flexible circuit board is arranged at one side of the light source back to the in-lightface, and electrically connected with the light source. Therefore, when the other elements of the backlight module are assembled, the upper back frame and the lower back frame are dismounted firstly,the other elements of the backlight module are assembled to the lower back frame; then the upper back frame and the lower back frame are assembled, thereby avoiding the installing blockage of the upper back frame and facilitating the installation of the backlight module.
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...
