It should be noted that an embodiment of the present application may only focus on changes to one or a few components. Other portions that are not introduced or not highlighted have different modifications in other embodiments, in this embodiment. Also applies.

It will be apparent that the electronic device 100 may also include other components, such as a memory, display screen, etc., which are not described herein because they are not related to the improvement of the present application.

The light guiding structure 3, the housing 1 and the electronic device 100 provided by the present application guide the light guiding structure 3 on the frame 1 of the housing 1 to guide the light emitted by the light source through the light guiding structure 3 on the frame 1. The screen area ratio can be effectively increased without occupying the space of the front screen. In addition, by providing the convex light-in portion R1 on the surface F0 of the light-guiding film 32 on which the transparent decorative member 31 is not attached, the light enters the light from the protrusion. When the portion R1 enters, the light guide film 32 is gradually weakened when it is conducted in a region outside the convex light incident portion R1, and exhibits an effect of gradation of the light emission luminance, thereby improving the display effect of the light emission.

The above is an embodiment of the present application. It should be noted that those skilled in the art can also make some improvements and retouching without departing from the principles of the embodiments of the present application. It is considered as the scope of protection of this application.
