Of course, if the first optical sensor 51 cannot be disposed at the position facing the first through hole 111, the first optical sensor 51 may be disposed at a position slightly shifted from the position facing the first through hole 111 according to specific situations, as long as the requirement that the first optical sensor 51 can receive the ambient light irradiated from the first through hole 111 to detect the ambient light parameter is satisfied, and the specific position where the first optical sensor 51 is disposed is not limited in the embodiment of the present application.

In practice, holes may not be punched in the back cover 4 exclusively for providing the third optical sensor 53, and the third optical sensor 53 may share one through hole with other functional components. When the terminal device further comprises the flash lamp 9, the flash lamp 9 is fixed at the top position in the cavity defined by the middle frame 1, the display screen 3 and the rear cover 4, and is usually arranged near the rear camera. In this case, the third optical sensor 53 may be disposed at a position adjacent to the flash lamp 9, the flash lamp 9 and the third optical sensor 53 may both correspond to the third through hole 41, as shown in fig. 14, the flash lamp 9 may emit a flash of light outward through the third through hole 41, and the third optical sensor 53 may also detect a parameter of the ambient light irradiated thereon through the third through hole 41.

It will be appreciated that for the case where the third optical sensor 53 shares the third through hole 41 with the flash 9, a third lens 73 may be disposed in the third through hole 41. The third lens 73 may be divided into two parts, one part being a lens adapted to the flash 9, the other part being a lens adapted to the third optical sensor 53, and the lens applied to the third optical sensor 53 part may be a convex lens or a plano lens.

Optionally, in order to avoid and reduce the influence of the flash lamp 9 on the detection of the ambient light parameter by the third optical sensor 53, a respective cut-off device may be provided therebetween. The specific structural arrangement between the flash lamp 9 and the third optical sensor 53 may be appropriately set, and the embodiment of the present application is not limited.

Alternatively, the third optical sensor 53 may share the third through hole 41 with other functional components in addition to sharing the third through hole 41 with the flash lamp 9, which is not limited in the embodiment of the present application.

The above description is only exemplary of the present application and should not be taken as limiting, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
