The embodiment of the application provides electronic equipment. The electronic device can be a smart phone, a tablet computer and the like. Referring to fig. 1, the electronic device 100 includes a cover plate 10, a display screen assembly 20, a circuit board 30, and a case 40.

Wherein the cover plate 10 is mounted to the display screen assembly 20 to cover the display screen assembly 20. The cover plate 10 may be a transparent glass cover plate. In some embodiments, the cover plate 10 may be a glass cover plate made of a material such as sapphire.

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.

Referring to fig. 2 and 3, the display panel assembly 20 includes a display panel 21, a convex lens 22 and a sensor assembly 23. The convex lens 22 mainly focuses light. The display screen 21 includes a first display area 201 and a second display area 202, the pixel density of the first display area 201 is lower than the pixel density of the second display area 202, and the area of the first display area 201 is smaller than the area of the second display area 202. The convex lens 22 and the sensor assembly 23 are disposed at one side of the first display region 201. The sensor element 23 faces the first display area 201, and the convex lens 22 is disposed between the first display area 21 and the sensor element 23.

In one embodiment, the display screen 21 may be a full-screen display screen, i.e., the display screen 21 includes only display regions and no non-display regions.

In one embodiment, the pixels of the first display region 201 include a pixel spacing region 2011, the pixel spacing region 2011 is a spacing region between adjacent pixels, and the transmittance of infrared rays and visible light in the pixel spacing region 2011 is much greater than the transmittance of the pixel region. Therefore, the convex lens 22 is disposed on the side corresponding to the pixel spacing area 2011, so that the light transmittance of the sensor assembly 23 can be better ensured.

It will be appreciated that the convex lens 22 and the sensor assembly 23 are disposed on the inside of the display screen 21. Here, the inner side refers to a side where the display screen 21 is not visible when viewed from the outside of the electronic apparatus 100. That is, the convex lens 22 and the sensor assembly 23 are located inside the electronic device 100.

Wherein the display 21 comprises a display layer 211. The display layer 211 is used to display information such as images and texts.

In some embodiments, the display screen 21 further includes a light shielding layer, which may be a thin layer structure made of foam or steel, and faces the convex lens 22. The light shielding layer 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 shading layer is provided with an opening. Wherein the aperture is arranged coaxially with the convex lens 22. That is, the axis of the opening coincides with the axis of the convex lens 22. The openings allow optical signals, acoustic signals, and the like to pass through.

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 convex lens 22. 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 convex lens 22.

After receiving the reflected signal B, the signal receiver 232 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.

The sensor assembly 23 faces the first display area 201, and since the pixel density of the first display area 201 is lower than the pixel density of the second display area 202, the infrared ray and the visible light can better penetrate through the sensor assembly, so as to enhance the signal intensity received by the signal receiver 232, and further improve the detection accuracy of the sensor assembly 23.

The convex lens 22 is arranged between the first display area 201 and the sensor assembly 23, and the convex lens 22 can converge light, so that the transmittance of a signal emitted by the signal emitter 231 can be improved, the signal intensity received by the signal receiver 232 can be enhanced, the detection accuracy of the sensor assembly 23 can be improved, and the accuracy of controlling the display screen to be turned off or turned on by the electronic device 100 can be improved.

In some embodiments, the signal emitter 231 is an infrared emitter for emitting infrared rays. The signal receiver 232 is an infrared receiver for receiving infrared rays.

In some embodiments, the Display 21 may be a Liquid Crystal Display (LCD) or Organic Light-Emitting Diode (OLED) Display, or the like. When the display screen 21 is a liquid crystal display screen, the display layer 211 may include a backlight plate, a lower polarizer, an array substrate, a liquid crystal layer, a color film substrate, an upper polarizer, and the like, which are sequentially stacked. When the display panel 21 is an organic light emitting diode display panel, the display layer 211 may include a base layer, an anode, an organic layer, a conductive layer, an emission layer, a cathode, and the like, which are sequentially stacked.

In some embodiments, referring to fig. 4 and fig. 5, the display screen 21 includes a first display area 201 and a second display area 202, and the pixel density of the first display area 201 is lower than the pixel density of the second display area 202. The first display area 201 is located at the upper right corner of the display screen 21, and the first display area 201 includes an area pixel control unit 2012 for controlling the on and off of the pixels of the first display area 201.

Since the first display area 201 at the upper right corner of the display screen 21 is a display status bar part, and status information such as time of the corresponding display electronic device has low requirements for pixels, even if the pixels of the first display area 201 are lower than the pixels of the second display area 202, the use of the user is not affected. It should be noted that, the above is only an example of the position of the first display area 201, and the first display area 201 may also be disposed at an upper left corner, a lower right corner, and the like, and is not limited herein.

When the electronic device is in a non-call state, as shown in fig. 4, the area pixel control unit 2012 controls the pixels of the first display area 201 to be turned on. When the electronic device is in a call state, as shown in fig. 5, the area pixel control unit 2012 controls the pixels of the first display area 201 to be turned off.

It can be understood that, when the electronic device is in a call, the distance between the human face and the display screen 21 needs to be detected in real time, and since the sensor assembly 23 is disposed on one side of the first display area 201, the pixels of the first display area 201 are turned off during the call, so that the influence of the first display area 201 on the light transmittance can be reduced to the maximum extent, and the detection accuracy of the sensor assembly 23 is ensured.

In some embodiments, as shown in FIG. 6, the convex lens 22 has a convex surface 221 and a flat surface 222. Wherein the convex surface 221 faces the sensor assembly 23 in the display screen assembly 20. The flat surface 222 faces the display screen 21 in the display screen assembly 20. The convex lens 22 may be a transparent lens made of a light-transmitting material. For example, the convex lens 22 may be a transparent glass lens.

It will be appreciated that the convex surface 221 of the convex lens 22 faces the sensor assembly 23 so that the convex lens 22 can act as a light collector. The signal emitted by the signal emitter 231 in the sensor assembly 23 can be emitted to the outside more, so as to reduce diffraction of the signal in the display screen assembly 20, and the signal reflected from the outside can be fed back to the signal receiver 231 through light condensation, so that the signal utilization rate can be improved, and the detection accuracy of the sensor assembly 23 can be improved.

In some embodiments, as shown in fig. 7, the convex lens 22 has a first convex surface 221 and a second convex surface 223. That is, the convex lens 22 is an elliptical lens. Both sides of the convex lens 22 are convex. Wherein the first convex surface 221 faces the sensor assembly 23 in the display screen assembly 20. The second convex surface 223 faces the display screen 21 in the display screen assembly 20.

It can be understood that, when both surfaces of the convex lens 22 are convex surfaces, the light-gathering effect of the convex lens 22 can be improved, and diffraction of signals in the display screen assembly 20 can be further reduced, so that more signals are emitted to the outside, thereby further improving the signal utilization rate and improving the detection accuracy of the sensor assembly 23, compared with the case that one surface of the convex lens 22 is convex and the other surface is a plane.

In some embodiments, as shown in fig. 8, the sensor assembly 23 includes a signal transmitter 231 and a signal receiver 232. Wherein the signal transmitter 231 and the signal receiver 232 are disposed adjacent to each other. In one embodiment, the distance d1 between the geometric center of the signal transmitter 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 into the first chip 24. The signal emitter 231 and the signal receiver 232 are disposed adjacent to each other, which may reduce the volume of the first chip 24.

In some embodiments, as shown in fig. 9, the sensor assembly 23 includes a signal emitter 231, a signal receiver 232, and an ambient light sensor 233. Among them, the ambient light sensor 233 is used to detect 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 233.

The signal transmitter 231, the signal receiver 232, and the ambient light sensor 233 are disposed adjacent to each other. The distance d3 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, the signal receiver 232, and the ambient light sensor 233 are packaged into a second chip 25.

Wherein the signal emitter 231, the signal receiver 232, and the ambient light sensor 233 are disposed adjacent to each other to reduce the volume of the second chip 25.
