In some embodiments, as shown in FIG. 2, display screen assembly 20 includes a display screen 21, and a sensor assembly 23. The display screen 21 is a full-screen display to achieve the effect of full-screen display, that is, the display screen 21 does not need to draw out a non-display area, but all display areas are display areas. The sensor assembly 23 is disposed below the display area of the display screen 21.
In some embodiments, the display screen 21 includes a fixed display region and a non-fixed display region for displaying fixed icons, the fixed display region has fewer corresponding pixel electrodes than the non-fixed display region, and the fixed display region has fewer liquid crystal molecules in the liquid crystal layer than the non-fixed display region; the sensor assembly 23 is disposed below the fixed display area.

Since the state information is fixed and is easy to know by a user, the display effect of the region can be general, the requirement is not high, the pixel electrode and the liquid crystal molecules in the region can be set to be sparse, and thus, when the sensor assembly 23 is arranged below the region, the detection signal emitted by the sensor assembly can effectively pass through the sparse place and is transmitted to the outside without being blocked by the dense pixel electrode and the liquid crystal molecules, and the transmittance of the signal emitted by the sensor assembly is effectively improved.

Because the sensor assembly 23 is arranged below the display area with fewer pixel electrodes and liquid crystal molecules, the detection signal emitted by the signal emitter 231 is not blocked by the dense pixel electrodes and the dense liquid crystal molecules, and can emit all signals to the outside, so that the transmittance of the signal emitted by the signal emitter is effectively improved, the signal intensity received by the signal receiver is enhanced, the detection accuracy of the sensor assembly is improved, and the accuracy of controlling the display screen to be turned off or on by the electronic equipment is improved.

Specifically, a groove 50 is formed below a liquid crystal layer of the display screen, the groove 50 corresponds to the fixed display area, and the sensor assembly is arranged in the groove 50. And a shading layer is arranged below the display screen. The light-shielding layer 22 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. Because the sensor assembly 23 is arranged below the display area with fewer pixel electrodes and liquid crystal molecules, the detection signal emitted by the signal emitter 231 is not blocked by the dense pixel electrodes and the dense liquid crystal molecules, and can emit all signals to the outside, so that the transmittance of the signal emitted by the signal emitter is effectively improved, the signal intensity received by the signal receiver is enhanced, the detection accuracy of the sensor assembly is improved, and the accuracy of controlling the display screen to be turned off or on by the electronic equipment is improved.
Referring to fig. 7, in other embodiments, the sensor assembly 23 is disposed below the display screen, which is as follows: the display screen 21 comprises a fixed display area and a non-fixed display area for displaying fixed icons, the number of pixel electrodes corresponding to the fixed display area is less than that of pixel electrodes corresponding to the non-fixed display area, and liquid crystal molecules in a liquid crystal layer corresponding to the fixed display area are less than that of liquid crystal molecules in the liquid crystal layer corresponding to the non-fixed display area; the sensor assembly 23 is disposed below the fixed display area. Specifically, a light shielding layer is arranged below the display screen, an opening is formed in the light shielding layer and corresponds to the fixed display area, and the sensor assembly is arranged below the opening. The light-shielding layer 22 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 signal transmitter 231 is used to transmit the detection signal a outwards. The detection signal a is transmitted to the outside through the opening 220 and the fixed display area. When the detection signal a contacts an external object 200 (e.g., a user's face), a reflected signal B is generated. The reflected signal B enters the signal receiver 232 through the fixed display area and the opening 220. Because the sensor assembly 23 is arranged below the display area with less pixel electrodes and liquid crystal molecules, the detection signal emitted by the signal emitter 231 is not blocked by the dense pixel electrodes and the dense liquid crystal molecules after being perforated, and all signals can be emitted to the outside, so that the transmittance of the signals emitted by the signal emitter is effectively improved, the signal intensity received by the signal receiver is enhanced, the detection accuracy of the sensor assembly is improved, and the accuracy of controlling the display screen to be turned off or turned on by the electronic equipment is improved.

In this embodiment, a light shielding layer 22 is attached to an inner surface of the display screen 21, an opening 220 is formed in the light shielding layer 22, and the sensor assembly 23 is disposed below the opening 220. The light shielding layer 22 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 sensor assembly 23 includes a signal transmitter 231 and a signal receiver 232. Wherein, the signal transmitter 231 is used for transmitting the detection signal a outwards. The detection signal a is transmitted to the outside through the opening 220 and the fixed display area. When the detection signal a contacts an external object 200 (e.g., a user's face), a reflected signal B is generated. The reflected signal B enters the signal receiver 232 through the fixed display area and the opening 220.

In some embodiments, the light-shielding layer 22 may be a thin layer structure made of foam or steel.
In some embodiments, as shown in fig. 3, when the signal emitted by the signal emitter 231 is an optical signal, the opening 220 of the light shielding layer 22 may be filled with a light transmissive material 214. The light-transmissive material 214 may allow the signal emitted by the signal emitter 231 to pass through, and may also provide some concealment to the internal structure of the electronic device 100. For example, the light transmissive material 214 may be an infrared ink.
In some embodiments, the sensor assembly 23 also includes an ambient light sensor. Wherein the ambient light sensor is used for detecting the intensity of 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.

Wherein the signal transmitter 231 and the signal receiver 232 are disposed adjacent to each other. The distance d1 between the geometric center of the signal emitter 231 and the geometric center of the signal receiver 232 is 2 to 14 millimeters.
In some embodiments, the signal transmitter 231 and the signal receiver 232 are packaged as a first chip. The signal transmitter 231 and the signal receiver 232 are disposed adjacent to each other, which may reduce the volume of the first chip.

Wherein the signal transmitter 231 and the signal receiver 232 are spaced apart from each other. The distance d2 between the signal emitter 231 and the signal receiver 232 is 2 to 14 millimeters. It is understood that the above distance is a distance between a geometric center of the signal transmitter 231 and a geometric center of the signal receiver 232. The signal emitter 231 and the signal receiver 232 are spaced from each other, so that the isolation between the signal emitter 231 and the signal receiver 232 can be improved, and the influence of the signal emitted by the signal emitter 231 on the signal receiver 232 can be reduced.
In some embodiments, the sensor assembly 23 includes a signal emitter 231, a signal receiver 232, and an ambient light sensor.
