The housing 100 is a supporting member of the mobile terminal, and provides a mounting position for other components. The casing 100 has a bezel 110. In a specific embodiment, the casing 100 may include an upper cover of the motherboard, and the upper cover of the motherboard includes a frame 110.

The display module 200 is mounted on the housing 100. The display module 200 includes a display screen 210 and a light-transmissive cover plate 220. The light-transmissive cover plate 220 covers the display screen 210, thereby protecting the display screen 210. The transparent cover 220 does not affect the display of the display screen 210. The transparent cover 220 is usually a glass cover. The light-transmitting cover plate 220 is usually adhered and fixed to the display screen 210 through optical glue.

The frame 110 forms a mounting groove. During the installation process, the display module 200 is installed in the mounting groove, and the edges of the light-transmitting cover plate 220 are overlapped and fixed on the frame 110. Generally, the light-transmitting cover plate 220 and the frame 110 are fixed. Adhesive and fixed by adhesive layer.

The light-transmissive cover plate 220 includes a non-display area 221 and a display area 222, and the non-display area 221 is connected to the display area 222, thereby forming the entire light-transmissive cover plate 220. In a specific implementation, the non-display area 221 is distributed around the display area 222.

A light guide 300 is provided on the inner side of the non-display area 221. The light guide 300 is usually a light guide plate, and of course, it may be a light guide structure of other shapes. The embodiment of the present disclosure does not limit the specific structure of the light guide 300. An accommodation space 400 is formed between the display screen 210 and the bezel 110. An indicator light 500 is arranged in the accommodation space 400. The non-display area 221 has a light transmitting area 2211 for indicating light. The light emitted by the light indicator 500 is under the function of the light guide 300. Eventually, the light will be emitted from the light-transmitting area 2211 to remind the user. A flexible printed circuit board (FPC) 600 for supplying power to the indicator 500 may be disposed between the display screen 210 and the bottom wall of the mounting groove of the housing 100.

Specifically, the light incident surface of the light guide 300 is opposite to the indicator light 500, so that the light emitted by the indicator 500 can enter the light guide 300 from the light incident surface and be transmitted. The light-emitting surface of the light guide 300 is opposite to the indication light transmission area 2211. The light guide 300 is used for transmitting the indication light emitted by the indicator light 500 to the indication light transmission area 2211, and finally emitted from the indication light transmission area 2211. .

In the embodiment of the present disclosure, the indicator light 500 is disposed below the non-display area 221 of the light-transmissive cover 220 and located between the display screen 210 and the frame 110, and then the light emitted by the indicator light 500 is transmitted through the light guide 300. The indication light transmitting area 2211 transmitted to the non-display area 221 finally achieves the indication function of the indicator light 500. The indicator light 500 is built under the light-transmissive cover 220, and then the light guide 300 is used to display the indicator light after being transmitted. Therefore, in the mobile terminal disclosed in the embodiment of the present disclosure, the indicator light 500 does not occupy the space of the frame 110. Therefore, the frame 110 does not need to be designed with a relatively large layout space, and the width of the frame 110 can be reduced, which is beneficial to increasing the screen ratio of the mobile terminal.

In order to improve the light emitted by the indicator 500 to be more uniform after being transmitted by the light guide 300, in an optional solution, a groove is provided on the light entrance surface of the light guide 300, and the indicator 500 is projected onto the groove on the light entrance surface. , And then can achieve diffuse reflection of light, and ultimately can improve the uniformity of light. There are various groove structures. In a specific embodiment, the groove may be a V-shaped groove. In an optional solution, the number of the grooves is at least two, which can improve the diffuse reflection effect and further improve the uniformity of light.

In an optional solution, the light emitting surface may be provided with an optical dot, and the optical dot can improve the light prompting effect of the indicator light 500.

In the actual light transmission process, in order to avoid unnecessary light leakage, in an optional solution, a region between the light entrance surface and the light exit surface on the light guide 300 may be provided with a light shielding portion, which can improve the utilization of light. Rate, while avoiding the impact of light leakage on other parts of the mobile terminal. Specifically, a light-shielding film A may be provided on a surface of the light guide 300 facing the light-transmissive cover 220, and a light-shielding film B may be provided on a surface of the light guide 300 facing away from the light-transmissive cover 220. Of course, other surfaces of the light guide 300 that do not need to leak light may also be provided with a light shielding film.

The light guide 300 can be fixed on the inner surface of the non-display area 221 by pasting. In this case, the light guide 300 can be assembled on the basis of the light-transmissive cover plate 220 to avoid setting and installing the light guide 300 separately. The structure can further effectively utilize the transparent cover 220. The surface of the light guide 300 opposite to the display screen 210 can be connected through the light-shielding adhesive 700. The light-shielding adhesive 700 can not only realize the connection, but also can shield the part. In a specific embodiment, the light-shielding adhesive 700 may be a light-proof silicone adhesive. Of course, the light-shielding glue 700 can also be made of other opaque glue.

Please refer to FIG. 1 again, the non-display area 221 may include a bottom non-display sub-region 2212 located at the bottom of the mobile terminal, indicating that the light transmission area 2211 is located in the middle of the bottom non-display sub-region 2212, and the indicator light 500 and the bottom non-display sub-region One end of the region 2212 is oppositely disposed, and the light guide 300 extends along the extending direction of the bottom non-display sub-region 2212 (usually the width direction of the mobile terminal). Indicating the above-mentioned setting position of the light transmitting region 2211 is beneficial to improving the appearance performance of the mobile terminal. Since the middle part of the bottom end of the mobile terminal is usually provided with other parts such as a charging port, the space under the light-transmissive cover 220 corresponding to this part is small. Therefore, the indicator light 500 is located at one end of the non-display sub-region 2212 at the bottom. This enables the indicator light 500 to be located at a corner of the mobile terminal, and the corner portion has a large volume of accommodation space, which makes the layout of the indicator light 500 easier.

In the mobile terminal disclosed in the embodiments of the present disclosure, there are various relative positional relationships between the indicator light 500 and the light guide 300. In a specific implementation, please refer to FIG. 5, the light guide 300ˊ is fixed in a non-display area.
