The display screen assembly 20 is mounted on the housing 40 to form a display surface of the electronic device 100. The display screen assembly 20 serves as a front case of the electronic device 100 and forms an enclosed space with the housing 40 for accommodating other electronic components of the electronic device 100. Meanwhile, the display screen assembly 20 forms a display surface of the electronic device 100 for displaying information such as images, text, and the like.

The circuit board 30 is mounted inside the housing 40 to accommodate the circuit board 30 in the closed space. The circuit board 30 may be a motherboard of the electronic device 100. The circuit board 30 is provided with a grounding point to realize grounding of the circuit board 30. Functional components such as a camera and a processor may be integrated on the circuit board 30. Meanwhile, the display screen assembly 20 may be electrically connected to the circuit board 30.

In some embodiments, display control circuitry is disposed on the circuit board 30. The display control circuit outputs an electrical signal to the display screen assembly 20 to control the display screen assembly 20 to display information.

The housing 40 is used to form the outer contour of the electronic device 100. The housing 40 may be made of plastic or metal. The housing 40 may be integrally formed.

In the embodiment of the present application, as shown in fig. 2, the display screen assembly 20 includes a display screen 21 and a sensor assembly 22. The display panel 21 includes a display layer 211 and a light-shielding layer 212 stacked. The display layer 211 is used to display information such as images and texts. The light-shielding layer 212 is used to hide the internal structure of the electronic device 100, so that a user can see the internal electronic components of the electronic device 100 through the display screen 21. The light-shielding layer 212 has an opening 213, and the opening 213 allows signals such as optical signals and acoustic signals to pass through. The sensor unit 22 is located on the side of the display screen 21 having the light shielding layer 212, and the sensor unit 22 is attached to the circuit board 30.

In some embodiments, as shown in FIG. 3, display screen 21 includes a display area 214 and a non-display area 215. Wherein the display area 214 performs the display function of the display screen 21 for displaying information. The non-display area 215 does not display information. The display screen 21 may include a plurality of non-display areas 215 spaced apart from each other. For example, non-display regions 215 are provided at the top and bottom of the display screen 21, respectively. The non-display area 215 may be used to set up functional components such as a camera, a receiver, and a fingerprint module.

In the embodiment of the present application, the opening 213 provided on the light shielding layer 212 of the display screen 21 is located in the display area 214 of the display screen 21. With reference to fig. 2, a plurality of light-gathering members 216 are disposed on a portion of the display layer 211 corresponding to the opening 213, so as to form a light-gathering display area S, and a projection of the light-gathering display area S on the light-shielding layer 212 covers the opening 213. That is, in some embodiments, the shape of the light-gathering display area S is equivalent to that of the opening 213.

The sensor assembly 22 can perform the proximity sensing function of the electronic device 100 through the opening 213, thereby eliminating the need for a separate opening in the non-display area 215 of the display screen 21.

Specifically, as shown in fig. 2, the sensor assembly 22 includes a signal transmitter 221 and a signal receiver 222. Wherein the signal transmitter 221 is used for emitting the optical signal a outwards. The optical signal a is transmitted to the outside through the opening 213 and the condensed display area S. The optical signal a contacts an external object 200 (e.g., a user's face) to generate a reflected signal B. The reflected signal B enters the signal receiver 222 through the light-gathering display area and the opening 213.

After receiving the reflected signal B, the signal receiver 222 may output the received signal to a processor of the electronic device 100 for processing, so as to control the display screen of the electronic device 100 to turn off or turn on.

In some embodiments, signal emitter 221 is an infrared emitter for emitting infrared light. The signal receiver 222 is an infrared receiver for receiving infrared rays.

In some embodiments, the opening 213 is a circular hole. The diameter of the opening 213 is 2 to 4 mm. In other embodiments, the opening 213 may be a square hole, an elliptical hole, or other holes. Accordingly, the spotlight display area S may be circular, square, elliptical, etc.

In some embodiments, as shown in fig. 4, the opening 213 of the light-shielding layer 212 may be filled with a light-transmissive material 217. The light-transmissive material 217 may allow a signal emitted by the signal emitter 221 to pass therethrough, and may also provide some concealment to the internal structure of the electronic device 100. For example, the light transmissive material 217 may be an infrared ink.

In some embodiments, the light-shielding layer 211 may be a thin layer structure made of foam or steel.

In the embodiments of the present application, the light gathering members may be arranged in various ways. For example, as shown in the left diagram of fig. 5, a plurality of light-gathering members 216 may be disposed on the display layer 211 at intervals corresponding to the portions of the openings 213, so that the light-gathering members 216 and the pixel electrodes on the display layer 211 may be alternately arranged. In this way, not only can the light-gathering member 216 in the light-gathering display area S perform a light-gathering function on the light signal emitted by the sensor assembly 22 and the reflected signal received thereby, but also the display area portion in the light-gathering display area S can perform a function of displaying information.

The light-focusing element 216 may be disposed at the edge of the opening, considering that the purpose of the light-focusing element is to adjust the optical path of the optical signal near the edge of the opening. Specifically, as shown in the right view of fig. 5, a plurality of light-gathering members 216 may be disposed around the edge of the opening 213, and the projections of the light-gathering members 213 on the light-shielding layer are located in the opening 213. That is, the plurality of light condensing members 216 are disposed along the inner edge of the light condensing display region S. Thus, the detection accuracy of the sensor assembly can be improved, and the information display function of the light-gathering display area S can be further improved compared with the structure shown in the left diagram in FIG. 5.

In some embodiments, the display screen 21 may be an Organic Light-Emitting Diode (OLED) display screen. Referring to fig. 6, the display layer 211 may include a lower substrate 2111, a light emitting layer 2112, an upper substrate 2113, and a polarizer 2114, which are sequentially stacked. The light-emitting layer 2112 may include an anode, an organic layer, a conductive layer, an emission layer, a cathode, and the like.

In some embodiments, as shown in fig. 6, a plurality of light concentrators 216 may be disposed on the underlying substrate 2111.

In some embodiments, referring to fig. 7, a plurality of light concentrators 216 may be disposed on the luminescent layer 2112.

In some embodiments, as shown in fig. 8, a plurality of light collectors 216 may be disposed on the luminescent layer 2112 and the underlying substrate 2113, respectively. Specifically, a plurality of light-collecting members 216 may be disposed at intervals and offset on the portion of the light-emitting layer 2112 corresponding to the opening 213 and the portion of the lower substrate 2111 corresponding to the opening 213, so that the space between the light-collecting members 216 may be filled with the organic light-emitting material, so as to subsequently realize the information display function of the light-collecting display region S.

In some embodiments, the light concentrator 216 may be a transparent lens made of a light transmissive material. In particular, the light gathering member 216 may be a convex lens.

In some embodiments, as shown in fig. 9, the light concentrator 216 has a first convex surface 2161 and a second convex surface 2162. That is, the light gathering member 216 is an elliptical lens with a thick middle and thin sides. Both sides of the light-concentrating member 216 are convex. The first convex surface 2161 faces the opening 213, and the second convex surface 2162 faces the polarizer 21142.

It can be understood that when both sides of the light-focusing element 216 are convex, the light-focusing effect of the light-focusing element 216 can be improved, and the diffraction of the signal in the display screen assembly 20 can be further reduced, so that the signal can be more emitted to the outside, thereby further improving the signal utilization rate and improving the detection accuracy of the sensor assembly 22.

It can be seen that, by providing the opening 213 on the light shielding layer 212 of the display screen 21 and providing the light gathering member 216 between the display screen 21 and the sensor assembly 22, the transmittance of the signal emitted by the signal emitter 221 can be improved, so as to enhance the signal strength received by the signal receiver 222, and further improve the detection accuracy of the sensor assembly 22, thereby improving the accuracy of the electronic device 100 in controlling the display screen to turn off or turn on.

In some embodiments, as shown in fig. 10, sensor assembly 22 includes a signal transmitter 221 and a signal receiver 222. Wherein the signal transmitter 221 and the signal receiver 222 are disposed adjacent to each other.

Wherein the signal transmitter 221 and the signal receiver 222 are disposed spaced apart from each other. The distance d2 between signal transmitter 221 and signal receiver 222 is 2 to 14 millimeters. It is understood that the above distance is a distance between a geometric center of the signal transmitter 221 and a geometric center of the signal receiver 222. The signal transmitter 221 and the signal receiver 222 are spaced apart from each other, so that the isolation between the signal transmitter 221 and the signal receiver 222 can be improved, and the influence of the signal transmitted by the signal transmitter 221 on the signal receiver 222 can be reduced.

In some embodiments, the signal transmitter 221 and the signal receiver 222 are packaged as the first chip 24.

In some embodiments, as shown in fig. 12, the sensor assembly 22 includes a signal transmitter 221, a signal receiver 222, and an ambient light sensor 223. Wherein the ambient light sensor 223 is used to detect the intensity of the ambient light. The electronic device 100 may adjust the brightness of the display screen 21 according to the intensity of the ambient light detected by the ambient light sensor 223.

The signal transmitter 221, the signal receiver 222, and the ambient light sensor 223 are disposed adjacent to each other. The distance d3 between the geometric center of the signal transmitter 221 and the geometric center of the signal receiver 222 is 2 to 14 millimeters.

The signal transmitter 221, the signal receiver 222, and the ambient light sensor 223 are disposed spaced apart from each other. The distance d4 between signal transmitter 221 and signal receiver 222 is 2 to 14 millimeters. It is understood that the above distance is a distance between a geometric center of the signal transmitter 221 and a geometric center of the signal receiver 222. The signal emitter 221, the signal receiver 222 and the ambient light sensor 223 are arranged at intervals, so that the isolation among the signal emitter 221, the signal receiver 222 and the ambient light sensor 223 can be improved, and the influence of the signal emitted by the signal emitter 221 on the signal receiver 222 and the ambient light sensor 223 can be reduced.
