Referring to fig. 2, in the present embodiment, the electronic device 1 further includes a cover plate 13. The cover 13 is located at the outermost side of the electronic device 1. The cover 13 is located on the front side of the display screen 10. A finger can touch the cover plate 13. The cover 13 is a transparent cover that can transmit light. The cover 13 may be a glass cover, a resin cover, or the like.

In this embodiment, the display 10 may be a liquid crystal display. The display screen 10 may include a display module 14 and a backlight module 15. The cover 13, the display module 14, and the backlight module 15 are stacked in this order from the outside toward the inside of the electronic apparatus 1. For convenience of illustration, it is specified that the direction from the cover plate 13 to the backlight module 15 is from top to bottom, that is, the cover plate 13 is located above the display module 14, and the backlight module 15 is located below the display module 14.

The display module 14 is disposed on one side of the cover plate 13. Light enters the light-transmitting channel 16 through the cover plate 13.

The backlight module 15 has a through hole 17 formed at the projection of the backlight module 15 in the light-transmitting channel 16. The through holes 17 and the display module 14 form blind holes 18 of the display screen 10. The optical component 20 is disposed opposite to the through hole 17. The light enters the light-transmitting channel 16 of the display module 14 through the cover plate 13, and enters the through hole 17 through the light-transmitting channel 16, so as to provide incident light for the optical assembly 20 located below the through hole 17. The shape of the through hole 17 may be adapted to the shape of the optical component 20 to facilitate mounting of the optical component 20. It will be appreciated that the cross-section of the through-hole 17 may be square, circular, oval or the like.

The control plate 21 is disposed corresponding to the blind hole 18, and is disposed opposite to the through hole 17. The shape of the control board 21 is matched with the shape of the through hole 17, so that the optical sensor 23 and the light-emitting device 22 on the control board 21 can be ensured to utilize the area of the through hole to the maximum, the light-sensing performance of the optical sensor 23 is further ensured, and the light-emitting area of the light-emitting device 22 is increased as much as possible. The control board 21 may be a circuit board.

It is understood that the area of the control board 21 may be larger than that of the through hole 17, so as to ensure that the optical sensor 23 and the light-emitting device 22 on the control board 21 can be effectively utilized.

The optical sensor 23 and the light emitting device 22 face the light transmission channel 16 of the display screen 10. The optical sensor 23 is used for sensing light incident from the light transmission channel 16. The position of the optical sensor 23 does not affect its normal operation. The light-emitting device 22 is used to generate light, which may also propagate illumination light outwardly through the light-transmissive channel 16.

When the control panel 21 controls the optical sensor 23 to be turned on for work, the light-emitting device 22 is turned off; when the optical sensor 23 is not operated, the light emitting device 22 is turned on to emit light.

When the optical sensor 23 is operated, the optical performance of the optical component 20 is ensured to be achieved. When the optical assembly 20 does not need to work, that is, the optical sensor 23 does not need to work, the light emitting device 22 starts to emit light, so that the light emitting device 22 can provide backlight for the display screen 10 at the position of the blind hole 18, the display module 14 at the position can display, and the display pattern of the display screen 10 at the position of the blind hole 18 is ensured to be complete.

It is understood that the light emitting device 22 may be an LED lamp, a light emitting chip or pixel, or the like.

Specifically, in the present embodiment, the light emitting devices 22 and the optical sensors 23 are uniformly distributed on the control board 21. Specifically, the light emitting devices 22 are distributed annularly, the optical sensors 23 are also distributed annularly, and the rings of the light emitting devices 22 and the rings of the optical sensors 23 are arranged alternately. The ring of light emitting devices 22 and the ring of optical sensors 23 may facilitate the operation of mounting the light emitting devices 22 and the optical sensors 23. Specifically, in the present embodiment, the shape of the ring of the light emitting device 22 and the ring of the optical sensor 23 is adapted to the shape of the control board 21, and the ring of the light emitting device 22 and the ring of the optical sensor 23 are rectangular rings.

The ring of light emitting devices 22 and the ring of optical sensors 23 may be equally spaced. The light emitting devices 22 and the optical sensors 23 can be uniformly distributed on the control board 21.

In other embodiments, the light emitting devices 22 and the optical sensors 23 may be alternately arranged at intervals. The arrangement positions and the arrangement modes of the light emitting device 22 and the optical sensor 23 are not limited, as long as the light emitting device 22 and the optical sensor 23 can be uniformly distributed on the surface of the control board 21, the light emitting device 22 can provide backlight with uniform light intensity for the display screen at the position of the blind hole 18, the optical sensor 23 can uniformly collect framing incident light, and the normal use function of the optical device 20 is ensured.

The occupied area of the optical sensor 23 is large, so that the optical function of the optical sensor 23 can be ensured, and the optical component 20 can work normally. Therefore, on the premise that the optical assembly 20 can work normally, the light-emitting device 22 emits light to display the position of the blind hole 18, so that the electronic device can achieve the display effect of a full screen.

Referring to fig. 5, in this embodiment, the display screen 10 may further include a display driving chip 19. The display driving chip 19 is electrically connected to the control board 21, and the display driving chip 19 supplies power to the control board 21. When the display driving chip 19 drives the display screen to display images, the control board 21 can be powered on to be turned on, and the control board 21 can control whether the light-emitting device 22 emits light according to the using state of the optical component.

The display driver chip 19 is electrically connected to the control board 21. The display driving chip 19 controls the light intensity of the display screen, and the control board 21 also controls the light intensity of the light emitting device 22 according to the light intensity controlled by the display driving chip 19, so as to ensure that the light intensity at each position of the display screen is uniform, and avoid the too strong or too weak light intensity displayed at the blind hole 18.

The optical sensor 23 may perform the function of an optical component. When the optical assembly does not need to work, the light-emitting device 22 on the control board 21 can provide backlight for the display screen at the position of the blind hole 18, so that the display screen at the position of the blind hole 18 cannot be displayed due to the blind hole 18, and the electronic device can realize a full-screen.
