The frame 210, the main board 220 and the light shielding film 150 form an accommodating cavity 141, the light emitting element 140 is located in the accommodating cavity 141, one end of the light guiding film 130 is located in the accommodating cavity 141, and the other end of the light guiding film 130 extends out of the accommodating cavity 141 and extends to the first light transmitting area 121 along the surface of the frame 210.
The first end of the second light shielding portion 152 is connected to the main board 220, and the second end of the second light shielding portion 152 is connected to the first end of the first light shielding portion 151.

In manufacturing, the pattern layer 120 may be formed on the glass cover 111 and then assembled with other parts, that is, the glass cover 111 and the pattern layer 120 may be a unitary structure.
The ink pattern layer 123 is used to form a pattern on the transparent cover 110, and the pattern may include a pattern displayed on the transparent cover 110 and a pattern of an electronic device atmosphere lamp. The pattern of the electronic device atmosphere lamp is the pattern of the first light-transmitting area 121.
For example, as shown in fig. 7, the pattern of the first light-transmitting region 121 may be a ring shape, which is located at the edge of the rear cover, surrounding the rear cover of the electronic device.

The pattern layer 120 is provided with a specular reflection layer, which may be provided on the ink pattern layer 123. Because part of the light is absorbed by the pattern layer 120 or the transparent cover 110 during the light transmission process, the light at the position of the specular reflection layer can be totally reflected by the specular reflection layer, thereby forming a local highlighting effect. Wherein the specular reflective layer may be specular silver.

The optical adhesive layer 125 is formed on the side of the plating texture layer 124 away from the transparent cover 110, the optical adhesive layer 125 can form reverse optical textures during printing, and different optical textures have different reflection effects on light, so that different light and shade effects at different positions can be formed.
The pattern layer 120 is provided with a specular reflection layer, which may be provided on the ink pattern layer 123. Because part of the light is absorbed by the pattern layer 120 or the transparent cover 110 during the light transmission process, the light at the position of the specular reflection layer can be totally reflected by the specular reflection layer, thereby forming a local highlighting effect. Wherein the specular reflective layer may be specular silver.
The atmosphere lamp of the electronic device may be located at the edge of the rear cover, on the basis of which the projection of the first light-transmitting area 121 on the transparent cover 110 is located at the edge of the transparent cover 110.
