In an embodiment, the material of the cover plate 130 may be glass or sapphire. In one embodiment, cover 130 is a planar glass that is easy to process. In other embodiments, cover plate 130 may also be a curved glass, such as 2.5D glass or 3D glass. Curved glass enables the mobile terminal 10 to have a better appearance.
In an embodiment, the light sensor 310 has a substantially rectangular block shape, and the light incident surface 311 of the light sensor 310 faces the first surface 131. The ambient light can pass through the cover 130 and be incident on the light incident surface 311, and the light sensor 310 can receive the ambient light and convert the brightness of the ambient light into an electrical signal. Further, in an embodiment, the light incident surface 311 of the light sensor 310 is a plane. It is understood that in other embodiments, the light incident surface 311 may be a curved surface.
In an embodiment, the first flexible circuit board 120 is connected to the non-display area 113 of the display screen 110, and the light sensor 310 is located between the non-display area 113 and the first surface 131 of the cover plate 130, where the front projection of the light sensor 310 on the reference plane overlaps with the front projection of the non-display area 113 on the reference plane in whole or in part. In the above structure, the light sensor 310 is fully overlapped or partially overlapped with the non-display area 113 of the display 110 in the length direction of the mobile terminal 10, so that the increase in size in the length direction of the mobile terminal 10 is avoided to provide an installation space for the light sensor 310, thereby being beneficial to improving the screen ratio of the mobile terminal 10. Further, in one embodiment, the front projection of light sensor 310 onto the reference plane is located within the front projection of non-display area 113 of display screen 110 onto the reference plane.

For example, an adhesive may be provided on the bottom wall of the positioning groove 135 to fixedly connect the light sensor 310 with the cover plate 130. In addition, since the thickness of the cover 130 at the position where the positioning groove 135 is formed can be made thinner, it is advantageous for the ambient light to be incident on the light incident surface 311 of the light sensor 310.
Referring to fig. 5 and 6, in an embodiment, the mobile terminal 10 may further include a front case 400 coupled with the rear case 200, the front case 400 being disposed at a side of the first surface 131 of the cover 130, and the front case 400 being located between the cover 130 and the rear case 200. In one embodiment, the front case 400 is a support structure formed by injection molding, and the front case 400 may be used to support the display 110 and other electronic components inside the mobile terminal 10. For example, in an embodiment, the front case 400 is connected to the cover 130, and the front case 400 is connected to the display 110, and a recess structure is formed on the front case 400, so that the electronic components of the mobile terminal 10 may be fastened in the recess structure on the front case 400, so that the electronic components are effectively supported.

Specifically, in an embodiment, the sidewall of the accommodating groove 410 may be matched with the outer circumference of the optical sensor 310, and the optical sensor 310 is at least partially accommodated in the accommodating groove 410. For example, in one embodiment, the cross section of the accommodating groove 410 is substantially rectangular, and the light sensor 310 is embedded in the accommodating groove 410 and is fixedly connected with the front case 400 through the accommodating groove 410. The gap between the sidewall of the receiving groove 410 and the outer circumference of the photo sensor 310 may be filled with adhesive to make the connection of the photo sensor 310 with the front case 400 more firm. In an embodiment, a light entrance hole 420 is formed on the bottom wall of the accommodating groove 410, the light entrance hole 420 penetrates through the front housing 400, the outer periphery of the light entrance hole 420 is abutted against the light sensor 310, and ambient light can be incident from the second surface 133 of the cover plate 130, exit from the first surface 131 of the cover plate 130, and enter the light entrance surface 311 of the light sensor 310 through the light entrance hole 420.
Further, referring to fig. 7 and 8, in an embodiment, the mobile terminal 10 may further include a main board 500, the rear case 200 is covered on the main board 500, and the main board 500 is located between the cover 130 and the rear case 200. The main board 500 is connected with the front case 400 by a threaded connection or by welding or bonding. Electronic components such as a controller, a memory, an antenna module, etc. of the mobile terminal 10 may be disposed on the main board 500. In an embodiment, the motherboard 500 uses a printed circuit board (PCB, printed Circuit Board) as a supporting structure, and a complex circuit structure may be disposed on the motherboard 500, and electronic components such as a controller and a memory, and the circuit structure on the motherboard 500 are part of the motherboard 500. The electronic components such as the display 110 may be communicatively coupled to the motherboard 500 such that the controller of the mobile terminal 10 may control the electronic components such as the display 110. In one embodiment, light sensor 310 may be coupled to motherboard 500. For example, the light sensor 310 may be fixedly attached to the motherboard 500 by adhesive or other attachment means. In an embodiment, a clearance groove (not shown) may also be formed on the motherboard 500, and the light sensor 310 passes through the clearance groove and is connected to the motherboard 500. The use of the void-avoiding groove may prevent the thickness of the mobile terminal 10 from increasing too much due to the superposition of the light sensor 310 and the main board 500, thereby facilitating the thinning of the mobile terminal 10.
In an embodiment, the display 110 is communicatively connected to the motherboard 500 through the first flexible circuit board 120, and the controller of the motherboard 500 can control the display of the display 110 through the first flexible circuit board 120. The light sensor 310 is communicatively connected to the main board 500 through the second flexible circuit board 320, and the light sensor 310 converts the brightness of the ambient light into an electrical signal and transmits the electrical signal to the controller of the main board 500 through the second flexible circuit board 320. The controller of the main board 500 can adjust the display brightness of the display screen 110 according to the brightness of the ambient light so that the user can comfortably view the information on the display screen 110. For example, when the ambient light level is low, the controller appropriately reduces the display brightness of the display screen 110, so that the display brightness of the display screen 110 can be prevented from being dazzled; when the brightness of the ambient light is high, the controller appropriately increases the display brightness of the display screen 110 so that the user can better see the information displayed on the display screen 110.
In the embodiment in which the first flexible circuit board 120 and the second flexible circuit board 320 are integrally formed, the above structure can avoid providing the circuit interface for the second flexible circuit board 320 on the motherboard 500 alone, so that the connection structure of the light sensing element 300 and the motherboard 500 can be simplified, and the occupied space of the circuit interface can be reduced. For example, when the first flexible circuit Board 120 and the second flexible circuit Board 320 are integrally formed, a separate Board-to-Board (BTB) structure is not required for the light sensor 310 to realize the communication connection between the light sensor 310 and the motherboard 500, so that the connection structure between the light sensing element 300 and the motherboard 500 is simplified, and the occupied space of the Board-to-Board structure is reduced. In addition, when the first flexible circuit board 120 and the second flexible circuit board 320 are integrally formed, the first flexible circuit board 120 and the second flexible circuit board 320 can be attached to the front case 400, and then the main board 500 is covered on the front case 400 to form a tight connection structure, so as to save the internal space of the mobile terminal 10. In other embodiments, the mobile terminal 10 may further include a third flexible circuit board (not shown), where the first flexible circuit board 120 and the second flexible circuit board 320 are connected to one end of the third flexible circuit board through a board-to-board structure, and the other end of the third flexible circuit board is connected to the motherboard 500 through a board-to-board structure. The above structure can also avoid providing the first flexible circuit board 120 and the second flexible circuit board 320 with independent circuit interfaces on the main board 500, thereby simplifying the connection structure of the light sensing element 300 and the main board 500 and reducing the occupation space of the circuit interfaces. In other embodiments, the first flexible circuit board 120 and the second flexible circuit 320 board may be separately connected to the main board 500.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
