The minimum thickness of the electronic device along the Z direction is 9.9mm, which is not beneficial to the lightening and thinning of the electronic device. In order to further improve the electronic device, the embodiments of the present disclosure provide the following technical solutions.

As shown in fig. 2 and 3, an embodiment of the present disclosure provides an electronic device including:

a back plate 110;

a light source mounted on the back plate 110;

the light guide plate 122 is installed in the back plate 110, and the light guide plate 122 has a light incident surface and a light emitting surface; the light incident surface is aligned with the light source;

and an optical composite film 123 disposed on the light guide plate 122 for diffusing light and changing a light transmission direction so that the light is emitted from a predetermined direction.

In the embodiment of the disclosure, light rays such as visible light of the light source enter the light guide plate through the light incident surface of the light guide plate, and are emitted from the light emitting surface after the light guide plate performs the actions such as reflection and refraction of light, so that the point light source or the line light source is converted into the surface light source. The optical composite film is positioned on the light guide plate and opposite to the light-emitting surface, and can diffuse light incident from the light-emitting surface, refract, reflect, scatter and the like, so that the light is emitted from a preset direction, and a uniform and high-brightness light source is provided for the display panel. Therefore, the optical composite film has the functions of a plurality of films, for example, the optical composite film has both the functions of a prism sheet and a diffusion sheet, and the functions of the prism sheet and the diffusion sheet are integrated.

In a non-limiting aspect, the optical composite film is a sheet-like structure, and the optical composite film includes a substrate and at least two functional layers formed on a surface of the substrate, wherein a portion of the functional layers has a function of a prism sheet, and a portion of the functional layers has a function of a diffusion sheet, and the plurality of functional layers share one substrate to respectively implement different functions of the plurality of films. Therefore, the optical composite film reduces the number and thickness of substrates with respect to a plurality of sheets separated from each other, each of which requires the provision of a substrate.

Moreover, for a plurality of diaphragms that separate from each other, the optical composite film of the embodiment of the present disclosure also reduces gaps between the plurality of diaphragms and the number of diaphragms, thereby reducing the overall thickness of the plurality of diaphragms, reducing the thickness of the whole backlight module and the electronic device having the backlight module, and facilitating the implementation of the lightness and thinness of the electronic device. In addition, the optical composite film is used, so that the installation steps of the backlight module and the electronic equipment are simplified, the abrasion caused by relative movement among the plurality of diaphragms is reduced, and the influence on the display effect of the electronic equipment is reduced.

Without limitation, the preset directions are: towards the display panel in the electronic device.

Compared with the backlight module comprising two layers of prism sheets in the related art, the structure is simplified, and the thickness of the backlight module is favorably reduced.

Generally, a plurality of scattering particles with different particle diameters are distributed on the surface of the prism structure, the plurality of scattering particles form a diffusion structure layer, and when light incident from the light-emitting surface of the light guide plate passes through the optical composite film, the diffusion structure layer scatters the light to achieve an atomization effect, so that a soft light effect is achieved.

The scattering particles include, but are not limited to, metal ions or inorganic particles, and may also be at least one of organic particles, composite particles, and hollow pores. For example: silica particles.
