The number of the light holes 210 may be equal to the number of the cameras 500, so that each light hole 210 is provided in one-to-one correspondence with each camera 500.

In an embodiment, the light hole 210 can be opened at any feasible position of the display screen 200, such as the upper left corner, the upper right corner, and the like of the display screen 200. The light hole 210 may be a circular hole, so that the size of the light hole 210 can be controlled while the structure of the camera 500 is adapted, and the processing process of the display screen 200 is simplified.

In the mobile terminal disclosed in the embodiment of the present invention, the light hole 210 is formed in the display screen 200, at least a part of the camera 500 is located in the light hole 210, and the light hole 210 can realize the positioning of the camera 500, so that a camera support is not required to be arranged, the size of the light hole 210 can be designed to be smaller, the screen occupation ratio of the mobile terminal is improved accordingly, and the appearance of the whole mobile terminal is simpler. Meanwhile, a driving mechanism is not required to be arranged to drive the camera 500 to ascend and descend, so that the structure of the mobile terminal is simpler.

In addition, when the camera 500 is positioned through the light-transmitting hole 210, the positioning accuracy of the camera 500 is also higher.

In a further embodiment, the mobile terminal disclosed in the present invention may further include an elastic positioning element 600, wherein the elastic positioning element 600 is disposed on an outer surface of the camera 500, and at least a portion of the elastic positioning element 600 is located in the light hole 210 formed in the display 200 and is in positioning fit with the light hole 210. First, the camera 500 can be positioned and matched with the light hole 210 through the elastic positioning member 600, and the elastic positioning member 600 has certain elasticity, so that the size of the light hole 210 is further reduced, the installation and the positioning of the camera 500 are not hindered, and the positioning accuracy of the camera 500 and the light hole 210 can be improved. In addition, once mobile terminal falls etc. the circumstances, elastic positioning element 600 can prevent that camera 500 from taking place direct collision with other spare parts to absorb the impact force, consequently elastic positioning element 600 can protect camera 500, makes camera 500's life-span prolong to some extent.

In order to improve the compactness of the mobile terminal, a through hole 121 may be formed in the main board upper cover 120, and a part of the camera 500 is located in the through hole 121. After the elastic positioning member 600 is disposed, a portion of the elastic positioning member 600 is also located in the through hole 121. At this time, the elastic positioning member 600 extends into the through hole 121, so that the contact area between the elastic positioning member 600 and the camera 500 is larger, and the positioning effect and the protection effect of the camera 500 are better. Further, the elastic positioning member 600 may be a ring structure disposed around the outer circumferential direction of the camera 500 to obtain more excellent positioning and protecting effects.

Optionally, the elastic positioning element 600 may be a silicone element, and the silicone element may be specifically bonded to the camera 500. The elastic positioning member 600 is made of a silica gel material, so that the elastic positioning member 600 has excellent temperature resistance, weather resistance, electrical insulation and other properties, and is long in service life and high in reliability.

In order to improve the fixing reliability of the camera 500, the housing 100 further includes a mounting bracket 140, the mounting bracket 140 and the display screen 200 are respectively located at two sides of the circuit board 400, and at least a portion of the camera 500 is fixedly connected to the mounting bracket 140. The mounting bracket 140 can contact the camera 500 over a large area, so that the camera 500 can be more reliably mounted in the housing 100. Alternatively, a portion of the camera 500 is fixedly connected to the mounting bracket 140, and another portion is fixedly connected to the middle frame 110. The camera 500, the middle frame 110, the main board upper cover 120 and the mounting bracket 140 can be assembled together by the arrangement, so that a structure with higher strength is formed.

In a further embodiment, the mobile terminal may further include a buffer foam 700, and a portion of the buffer foam 700 is located between the camera 500 and the mounting bracket 140, and another portion is located between the camera 500 and the middle frame 110.

Meanwhile, the middle frame 110 and the mounting bracket 140 are connected together by the buffer foam 700, so that the relative position accuracy of the middle frame 110 and the mounting bracket 140 is higher, and the position accuracy of the camera 500 is further improved.

Optionally, a sealing foam 800 may be further disposed between the camera 500 and the motherboard upper cover 120, and the camera 500 is in sealing fit with the motherboard upper cover 120 through the sealing foam 800, so that on one hand, the sealing property between the camera 500 and the motherboard upper cover 120 can be ensured, and impurities in an external environment are prevented from entering the camera 500; on the other hand, the sealing foam 800 has a deformation capability, so when the mobile terminal falls down, the sealing foam 800 can absorb the impact force to prevent the camera 500 from directly colliding with the motherboard upper cover 120, and therefore the camera 500 can be protected by the sealing foam 800.

Since the camera 500 is closer to the display 200, the light emitted from the display 200 may adversely affect the imaging operation of the camera 500. To solve this problem, a light shielding portion 900 may be provided in the light transmission hole 210, the light shielding portion 900 surrounding the axis of the light transmission hole 210. That is, the light shielding portion 900 has a ring-shaped structure extending along the outer circumferential direction of the light transmission hole 210. With such a structure, the light shielding portion 900 can more reliably shield the light emitted from the display screen 200, thereby improving the imaging quality of the camera 500.

Alternatively, in order to simplify the structure of the light shielding portion 900 and control the cost of the light shielding portion 900, the light shielding portion 900 may be provided as a light shielding paste.

The display panel 200 may be a multilayer structure, and in particular, the display panel 200 may comprise a first portion 220 and a second portion 230 arranged in a stack, wherein the first portion 220 is a light-transmissive portion and the second portion 230 comprises a non-light-transmissive portion. In order to ensure that light from the external environment can enter the camera 500, the light-transmitting hole 210 can be opened on the second portion 230, and at least a portion of the first portion 220 can face the light-transmitting hole 210, in other words, the first portion 220 covers the light-transmitting hole 210. After the arrangement, the first portion 220 does not need to be correspondingly perforated at the light hole 210, so that the normal operation of the camera 500 is not affected, and the structural strength of the first portion 220 is not weakened by the arrangement of the light hole 210, so that the structural strength of the whole display screen 200 is still high.

In an embodiment, the light-transmitting hole 210 may be entirely located at one side of the first portion 220, or may include a plurality of hole segments distributed at two sides of the first portion 220. In the latter configuration, when the light shielding portion 900 needs to be disposed, the light shielding portion 900 may be disposed in the hole section closest to the camera 500 to improve the light shielding effect.
