TECHNICAL FIELD

This application relates to the technical field of electronic apparatus, and in particular, to a display screen and an electronic device including the same.

BACKGROUND

Currently, full-screen electronic devices are becoming more and more mainstream due to their high screen-to-body ratio, which can significantly increase a size of a display region of a display screen without additionally increasing a size of the whole device. Nowadays, when achieving a high screen-to-body ratio, a problem that the full-screen electronic device needs to face is how to maintain normal operations of both a front camera and sensors located at a front screen.

At present, the full-screen electronic device is typically realized in two ways. The first way is to reserve a non-display region in a notch type or a water-drop notch type in the display screen for accommodation of components such as the front camera and sensors. The second way is to arrange the components such as the front camera and sensors in a pop-up/rotating structure, when needed, such structure can be popped out or rotated out from a body of the full-screen electronic device to allow the components such as the front camera and sensors to be exposed to perform corresponding operations. However, for the first way, reservation of the non-display region limits a further increase in the screen-to-body ratio; for the second way, the pop-up/rotating structure is prone to be damaged due to collision after being popped up.

Therefore, it is desirable to provide an improved full-screen solution.

In order to enable those skilled in the art to better understand solutions of the disclosure, technical solutions in implementations of the disclosure will be described clearly and completely hereinafter with reference to the accompanying drawings in the implementations of the disclosure. Apparently, the described implementations are merely some rather than all implementations of the disclosure. All other implementations obtained by those of ordinary skill in the art based on the implementations of the disclosure without creative efforts shall fall within the protection scope of the disclosure.

Referring toFIG. 1, which is a schematic cross-sectional view of part of a display screen100in an implementation of the disclosure. The display screen100includes a metal anode layer1, a semi-transparent cathode layer2, and a pixel unit layer3. The metal anode layer1includes multiple metal anodes11arranged at intervals. The semi-transparent cathode layer2includes multiple semi-transparent cathodes21. The pixel unit layer3is sandwiched between the metal anode layer1and the semi-transparent cathode layer2. The pixel unit layer3includes multiple pixel units31arranged at intervals. Each pixel unit31is located between a corresponding metal anode11and a corresponding semi-transparent cathode21. The display screen100has a preset region, and in the preset region of the display screen100, the semi-transparent cathode layer2further includes a light-shielding portion22and light-transmitting regions23surrounded by the light-shielding portion22. The light-shielding portion22is connected with the multiple semi-transparent cathodes21.

In an implementation, as illustrated inFIG. 1, the light-shielding portion22surrounds the multiple semi-transparent cathodes21. Further, the light-shielding portion22is on the same layer as the multiple semi-transparent cathodes21.

In an implementation, the multiple semi-transparent cathodes21are arranged at intervals.

As illustrated inFIG. 1, the light-shielding portion22fills regions of the semi-transparent cathode layer other than the semi-transparent cathodes21and the light-transmitting regions23.

In an implementation, as illustrated inFIGS. 5-7, the light-shielding portion22is disposed on the multiple semi-transparent cathodes21. As an example, the multiple semi-transparent cathodes21are integrally formed. As another example, the multiple semi-transparent cathodes21surround the multiple light-transmitting regions23.

As such, in this disclosure, in the preset region of the display screen100, the light-transmitting region23is disposed in the semi-transparent cathode layer2to allow light to pass through the display screen100. When the display screen100is used in an electronic device, photosensitive components arranged on the inner side of the display screen100can operate normally without a non-display region reserved for holing, which significantly increases a screen-to-body ratio of the display screen100.

In an implementation, the light shielding portion22is used to shield traces around the pixel unit31to reduce diffraction caused by the traces, and cooperates with the light-transmitting regions23to ensure an amount of light passing through.

In this disclosure, the light-shielding portion22is disposed on the semi-transparent cathode21, which means that the light-shielding portion22is carried on or attached to the semi-transparent cathode21, and is not limited to above the semi-transparent cathode21in terms of position or orientation.

In an implementation, the display screen100is used for display, for example, displaying corresponding display content for a user to view. The semi-transparent cathode layer2is close to a viewing surface of the display screen100for the user to view. It is noted that, the viewing surface of the display screen100refers to a surface for displaying contents for the user to view.

In an implementation, the light-transmitting regions23are hollow or made of a fully transparent material.

In implementations of the disclosure, an element made of a semi-transparent material has light transmittance less than 100%, and an element made of a fully transparent material has light transmittance of 100%.

That is, in some implementations, the light-transmitting regions23are hollow regions formed by one or more through-holes penetrating through the semi-transparent cathode layer2, or the light-transmitting regions23may be regions formed by further filling the one or more through-holes penetrating through the semi-transparent cathode layer2with fully transparent material. In an implementation, the fully transparent material may be fully transparent glass, resin, and other materials.

Referring toFIG. 2, which is a top view of the preset region of the display screen100. As illustrated inFIG. 2, in the preset region, the light-shielding portion22is disposed between or on adjacent semi-transparent cathodes21. The light-shielding portion22disposed between or on the adjacent semi-transparent cathodes21surrounds the light-transmitting regions23. Thus, the semi-transparent cathode layer2includes multiple light-transmitting regions23in the preset region.

As such, orthographic projections of the light-transmitting regions23on an incident surface1000of the display screen100are spaced apart from orthographic projections of the pixel units31sandwiched between the semi-transparent cathodes21and the metal anodes11on the incident surface1000, so that display of the preset region will not be affected, and light can pass through the preset region to allow elements such as photosensitive components to achieve corresponding functions.

In an implementation, the semi-transparent cathode21, the metal anode11, and the pixel unit31are stacked in a direction perpendicular to a plane of the display screen100. Thus, in the top view illustrated inFIG. 2, the semi-transparent cathode21, the metal anode11, and the pixel unit31are in the same region.

In an implementation, the photosensitive components may be luminance/light sensors, camera lens modules, and the like.

In an implementation, as illustrated inFIG. 1, the light-shielding portion22is used to shield metal traces L1around the pixel units31corresponding to the semi-transparent cathodes21. The light-shielding portion22is arranged according to arrangement positions of the metal traces L1that need to be shielded.

In some implementations, the light-shielding portion22shields a metal-trace L1region around corresponding pixel units and has a boundary line in a specific shape, and the light-transmitting region23is surrounded by the boundary line and thus has the specific shape. For example, the light-transmitting region23is circular, oval, or rectangular. That is, in some implementations, a projection of the metal-trace region on a plane where the light-shielding portion22is located falls within the light-shielding portion22. The light-shielding portion22shields the metal-trace region around the corresponding pixel units and then further ensures that the metal traces are completely shielded.

In other implementations, the light-shielding portion22exactly shields the metal-trace region around the corresponding pixel units, and a boundary line of the light-transmitting region23is aligned with edges of the metal-trace region. That is, in another implementation, the projection of the metal-trace region on the plane where the light-shielding portion22is located approximately coincides with the light-shielding portion22, and the boundary line of the light-transmitting region23surrounded by the light-shielding portion22is approximately the same as edges of the metal traces, which makes the light-transmitting region23a region with the edges of the metal-trace region as a boundary line. Here, the light-transmitting region23can have a maximum area, which effectively improves a light transmittance in the preset region.

In an implementation, as illustrated inFIG. 1andFIG. 2, the pixel unit31may include a red pixel unit311, a green pixel unit312, and a blue pixel unit313. The red pixel unit311, the green pixel unit312, and the blue pixel unit313constitute a pixel. The display screen100includes multiple pixels arranged in a matrix.

As illustrated inFIG. 1andFIG. 2, light-transmitting regions23are disposed between adjacent pixel units31of different colors. The light-transmitting regions23are disposed between adjacent red pixel unit311and green pixel unit312, between adjacent green pixel unit312and blue pixel unit313, and between adjacent blue pixel unit313and red pixel unit311. In an implementation, the orthographic projection of the light-transmitting region23on the incident surface1000is between the orthographic projections of adjacent pixel units31of different colors. Specifically, the orthographic projections of the light-transmitting regions23on the incident surface1000are between orthographic projections of adjacent red pixel unit311and green pixel unit312on the incident surface1000, between orthographic projections of adjacent green pixel unit312and blue pixel unit313on the incident surface1000, and between orthographic projections of adjacent blue pixel unit313and red pixel unit311on the incident surface1000.

As illustrated inFIG. 2, the light-transmitting regions23and the pixel units31are arranged in a same row. In an implementation, the light-transmitting region23, the red pixel unit311, the green pixel unit312, and the blue pixel unit313are arranged in a same row.

Referring toFIG. 3, which is a schematic top view of a preset region of a display screen100in another implementation. In another implementation, an orthographic projection of a light-transmitting region23on the incident surface1000of the display screen100may also fall within an orthographic projection of a rectangular region with four adjacent pixel units31in two adjacent rows as vertices on the incident surface1000of the display screen100. In an implementation illustrated inFIG. 3, spacing between adjacent pixel units31can be reduced and thus a resolution can be improved. In addition, the light-transmitting region23is disposed between four pixel units, and thus can be set as large as possible without having a relatively great impact on an overall light transmission effect.

Referring toFIG. 4, which is a schematic top view of a preset region of a display screen100in yet another implementation. In yet another implementation, light-transmitting regions23can be disposed in regions between adjacent pixel units31and in rectangular regions each with four adjacent pixel units31in two adjacent rows as vertices. That is, as illustrated inFIG. 4, some light-transmitting regions23are disposed between adjacent pixel units31, and some other light-transmitting regions23are disposed in the rectangular regions each with adjacent four pixel units31in two adjacent rows as vertices. In an implementation, as illustrated inFIG. 4, the light-transmitting regions23can be disposed in regions between adjacent pixel units31with different colors and in rectangular regions each with four adjacent pixel units31in two adjacent rows as vertices. In another implementation, as illustrated inFIG. 12, the light-transmitting regions23can be disposed in regions between adjacent pixel units31and in rectangular regions each with four adjacent pixel units31in two adjacent rows as vertices.

As such, light-transmitting regions23are disposed in rectangular regions each with four adjacent pixel units31in two adjacent rows as vertices and regions between adjacent pixel units31, which effectively improves the light transmission effect.

An orthographic projection of any light-transmitting region23on an incident surface1000of the display screen100is between orthographic projections of adjacent pixel units31on the incident surface1000or falls within an orthographic projection of a rectangular region with four adjacent pixel units31in two adjacent rows as vertices on the incident surface1000.

In an implementation, as illustrated inFIG. 2, an orthographic projection of each light-transmitting region23on the incident surface1000of the display screen100is between orthographic projections of adjacent pixel units on the incident surface1000.

In an implementation, as illustrated inFIG. 3, an orthographic projection of each light-transmitting region23on the incident surface1000of the display screen100falls within an orthographic projection of a rectangular region with four adjacent pixel units31in two adjacent rows as vertices on the incident surface1000.

In an implementation, as illustrated inFIG. 4, an orthographic projection of each of some light-transmitting regions23on the incident surface1000of the display screen100is located between orthographic projections of two adjacent pixel units on the incident surface1000, and an orthographic projection of each of the other light-transmitting regions23on the incident surface1000of the display screen100falls within an orthographic projection of a rectangular region with each four adjacent pixel units31in two adjacent rows as vertices on the incident surface1000.

In an implementation, a size of the light-transmitting region is larger than that of each pixel unit.

Referring back toFIG. 1, in some implementations, each semi-transparent cathode21has a same size as a pixel unit31corresponding to the semi-transparent cathode21. The light-shielding portion22includes an opaque cathode which is disposed between and coplanar with multiple semi-transparent cathodes21. The light-transmitting regions23are hollow regions surrounded by the opaque cathode or are formed by filling the hollow regions with a fully transparent material.

That is, in some implementations, as illustrated inFIG. 1, the light-shielding portion22is the opaque cathode disposed between the multiple semi-transparent cathodes21. The opaque cathode surrounds the light-transmitting regions23. The opaque cathode shields the metal traces L1. In an implementation, the light-shielding portion22is the opaque cathode surrounds the multiple semi-transparent cathodes21. The opaque cathode also surrounds the light-transmitting regions23. The opaque cathode, the multiple semi-transparent cathodes21, and the light-transmitting regions23are one the same layer.

Further, in some implementations, the semi-transparent cathodes21may be first patterned on each pixel unit31, the opaque cathode is then patterned on a layer where the semi-transparent cathodes21are arranged, and the opaque cathode and the semi-transparent cathodes21are connected to corporately form a complete semi-transparent cathode layer2. One or more through-holes are then defined in a region of the opaque cathode that does not correspond to the metal traces L1(e.g., the region between adjacent pixel units31and the rectangular region with four adjacent pixel units31in two adjacent rows as vertices) to form hollow regions as the light-transmitting regions23, or the hollow regions are further filled with a fully transparent material to form the light-transmitting regions23, and the rest of the opaque cathode that surrounds the light-transmitting regions23servers as the light-shielding portion22to shield the metal traces L1.

In an implementation, both the semi-transparent cathode21and the opaque cathode can be patterned via vapor deposition.

Referring toFIG. 5, which is a schematic cross-sectional view of part of a display screen100in another implementation. As illustrated inFIG. 5, each semi-transparent cathode21has a size larger than a pixel unit31corresponding to the semi-transparent cathode21. A projection of each pixel unit31on a plane where the corresponding semi-transparent cathode21is located falls within the semi-transparent cathode21. The light-shielding portion22is stacked on a surface of an edge region211of the semi-transparent cathode21. The edge region211is a region beyond a projection region of the pixel unit31on the semi-transparent cathode21. The edge region211is arranged according to arrangement positions of metal traces L1that need to be shielded. As illustrated inFIG. 5, the light-transmitting regions23are surrounded by the light-shielding portion22and the semi-transparent cathode21stacked with the light-shielding portion22.

That is, in the other implementation, the light-shielding portion22is stacked on the semi-transparent cathode21.

The projection of each pixel unit31on the corresponding semi-transparent cathode21falls within the semi-transparent cathode21, which can means that any point on a boundary of the projection of each pixel unit31on the corresponding semi-transparent cathode21is at a certain distance from the edge region211of the semi-transparent cathode21. As such, the projection of each pixel unit31on the corresponding semi-transparent cathode21completely falls within the corresponding semi-transparent cathode21, and the edge region211of the semi-transparent cathode21surrounds the semi-transparent cathode21.

In an implementation, the light-shielding portion22is disposed on a surface of the edge region of the semi-transparent cathode21close to the pixel unit31; or the light-shielding portion22is disposed on a surface of the edge region of the semi-transparent cathode21away from the pixel unit31.

In an implementation, a semi-transparent cathode21with a size larger than the pixel unit31may be first patterned on each pixel unit31, and then the light-shielding portion22may be patterned on a surface of the edge region211of the semi-transparent cathode21.

In an implementation, both the semi-transparent cathode21and the light-shielding portion22can be patterned via vapor deposition.

For example, as illustrated inFIG. 5, the light-shielding portion22is disposed on the surface of the edge region of the semi-transparent cathode21away from or opposite to the pixel unit31.

Referring toFIG. 6, which is a schematic cross-sectional view of part of a display screen100in yet another implementation. In yet another implementation, the light-shielding portion22is disposed on a surface of the edge region of the semi-transparent cathode21close to or toward the pixel unit31.

Referring toFIG. 7, which is a schematic cross-sectional view of part of a display screen100in other implementations of the disclosure. In other implementations, the light-shielding portions22can be disposed on both the surface of the edge region211of the semi-transparent cathode21close to the pixel unit31and the surface of the edge region of the semi-transparent cathode21away from the pixel unit31. Further, the light-shielding portion22disposed on the surface of the edge region211of the semi-transparent cathode21close to the pixel unit31is symmetrical to the light-shielding portion22disposed on the surface of the edge region211of the semi-transparent cathode21away from the pixel unit31.

That is, in other implementations, light-shielding portions22are disposed on the surface of the edge region211of each semi-transparent cathode21close to the pixel unit31and the surface of the edge region211of each semi-transparent cathode21away from the pixel unit31, and the light-shielding portions22on the two surfaces are symmetrically arranged.

In some implementations, the light-shielding portions22are disposed on surfaces of edge regions211of part of the semi-transparent cathodes21close to the pixel unit31, on surfaces of edge regions of another part of the semi-transparent cathode21away from the pixel unit31, and on surfaces of edge regions of the rest of the semi-transparent cathodes21close to the pixel unit31and surfaces of the edge regions211of the rest of the semi-transparent cathodes21away from the pixel unit31.

That is, the light-shielding portions are disposed on two opposite surfaces of the edge region211of the semi-transparent cathode.

In an implementation, when the light-shielding portion22is disposed on the surface of the edge region211of the semi-transparent cathode21, the light-shielding portion22can be formed on the surface of the edge region211of the semi-transparent cathode21via evaporation.

In an implementation, as illustrated inFIGS. 5-7, when the light-shielding portion22is disposed on the surface of the edge region211of the semi-transparent cathode21, the light-shielding portion22is made of an opaque material or a semi-transparent material.

For example, the light-shielding portion22can also be a semi-transparent cathode21. In an implementation, the light-shielding portion22can be made of a material same as the semi-transparent cathode21. The light-shielding portion22stacked on the semi-transparent cathode21thickens the semi-transparent cathode21in the edge region211, that is, the light-shielding portion22and the semi-transparent cathode21cooperate to provide an thickened semi-transparent cathode in the edge region211, and an opaque effect is achieved through the thickened semi-transparent cathode, thereby shielding the metal traces L1below.

For another example, the light-shielding portion22can also be an opaque cathode. The light-shielding portion22is stacked on the semi-transparent cathode21to shield the metal traces L1below.

In an implementation, the semi-transparent cathode21can be made of a semi-transparent indium tin oxide material or a semi-transparent metal material. A light transmittance of the semi-transparent cathode21is 50%. The opaque cathode can be made of opaque metal or other materials.

In an implementation, the display screen of the disclosure may be an organic light-emitting diode (OLED) display screen. As illustrated in figures such asFIGS. 1 and 5-7, each pixel unit31is sandwiched between one semi-transparent cathode21and one metal anode11. All semi-transparent cathodes21can serve as a common electrode to be grounded and at a voltage of 0 V. Each metal anode11serves as a pixel electrode and is connected with a driving circuit (not illustrated), and the driving circuit applies a corresponding driving voltage to the corresponding metal anode11according to data of contents to be displayed, so that the metal anode11drives the pixel unit31to emit light of a corresponding color, which in turn enables the display screen100to display corresponding contents.

In an implementation, the metal anode11in the metal anode layer1may be made of an opaque metallic material.

As illustrated in figures such asFIGS. 1 and 5-7, adjacent metal anodes11are spaced by a gap and adjacent pixel units31are spaced by a gap. Each light-transmitting region23communicates with the gap between corresponding metal anodes11and the gap between corresponding pixel units31. A projection of the gap between the pixel units31in a direction from the semi-transparent cathode layer2to the metal anode layer1overlaps or partially overlaps with the gap between the metal anodes11. A projection of the light-transmitting region23in a direction from the semi-transparent cathode layer2to the metal anode layer1falls within the gap between the metal anodes11and the gap between the pixel units31.

As such, the light-transmitting region23, the gap between the pixel units31, and the gap between the metal anodes11form an optical path channel. When photosensitive components are arranged on an inner side (that is, a non-viewing surface) of the display screen100, light can enter the photosensitive components through the light-transmitting region23, the gap between the pixel units31, and the gap between the metal anodes11in sequence, and corresponding functions of the photosensitive components can be realized. It is noted that, the non-viewing surface of the display screen100refers to a surface opposite to the viewing surface.

In an implementation, only six pixel units31in two rows and corresponding six metal anodes11and six semi-transparent cathodes21are illustrated inFIGS. 1 and 5-7. It is noted that, in the preset region, multiple pixel units31, multiple corresponding metal anodes11, and multiple corresponding semi-transparent cathodes21can be provided. Further, as illustrated inFIGS. 1 and 5-7, in terms of the semi-transparent cathodes21located at the two outermost sides, no shielding portion is disposed at one end of the semi-transparent cathode21that does not adjacent to any other semi-transparent cathode21, and thus no shielding portion is required.

Referring toFIG. 8, which is a top view of an overall display screen100. As illustrated inFIG. 8, the display screen100has a preset region Z1. The display screen100may be in a substantially rectangular shape and have two opposite long sides and two opposite short sides. The preset region Z1may be close to a short side of the display screen100.

In an implementation, a pixel resolution of the preset region Z1is lower than that of other regions of the display screen100. As such, the number of pixel units31in the preset region Z1will be reduced by lowing the pixel resolution of the preset region Z1, which can reserve a region for arrangement of the light-transmitting regions23to allow light to pass through.

In an implementation, a difference in pixel resolution between the preset region Z1and other regions of the display screen100is within a difference range that is indistinguishable to the naked eye. For example, the display screen100has a pixel resolution of 1920×1080 in a region beyond the preset region Z1and a resolution of 1280×720 in the preset region Z1, such that more region can be reserved for arrangement of the light-transmitting regions23, and the difference in resolution is indistinguishable the naked eye and therefore will not affect a visual effect for the user.

In an implementation, as illustrated inFIG. 8, the display screen100includes only one preset region Z1which is disposed close to a short side of the display screen100. The preset region Z1is spaced apart from each side of the display screen100by a certain distance.

Referring toFIG. 9, which is a top view of an overall display screen100in another implementation. In another implementation, the display screen100may include two preset regions Z1. For example, as illustrated inFIG. 9, the two preset regions Z1are respectively disposed close to two opposite short sides. Each of the two preset regions Z1has the aforementioned structures such as the metal anode layer1, the semi-transparent cathode layer2, the pixel unit layer3, and the light-transmitting region23.

By arranging the preset regions Z1close to two opposite short sides of the display screen100, when the display screen100is applied to an electronic device, photosensitive components such as camera lenses of a camera assembly can be arranged at positions corresponding to the two preset regions Z1of the electronic device, and a wide-angle shooting can be realized.

In an implementation of the disclosure, the light-transmitting region23is only disposed in the preset region Z1and not disposed in other regions of display screen100, and the other regions can have the same structure as an ordinary OLED display screen.

In some implementations, the light-shielding portion22can be formed in all regions of the display screen100to shield the metal traces L1around all pixel units31of the display screen100. In other implementations, the light-shielding portion22can also be disposed only in the preset region Z1. The metal traces L1can be shielded by means of black matrixes or the like in other regions of the display screen100beyond the preset region Z1, which is the same as an ordinary OLED display screen in structure. For example,FIG. 13illustrates a schematic bottom view of the preset region Z1of the display screen100with the light-shielding region22omitted, and as illustrated inFIG. 13, the metal traces L1are arranged around the pixel units31. In an implementation, the display screen100can also include a cover plate. The cover plate is disposed on the semi-transparent cathode layer2. That is, the cover plate is disposed on a side of the semi-transparent cathode layer2away from the pixel unit layer3, to protect the display screen100. The cover plate may be made of fully transparent glass, resin, or the like.

Referring toFIG. 10andFIG. 11,FIG. 10is a structural block diagram of an electronic device200in an implementation of the disclosure, andFIG. 11is a schematic cross-sectional view illustrating part of elements of an electronic device200. The electronic device200includes the display screen100described in any of the foregoing implementations. The electronic device200further includes a photosensitive component201.

In an implementation, as illustrated inFIG. 11, the photosensitive component300is disposed in the electronic device200and corresponds to the preset region Z1of the display screen100.

Specifically, as described above, adjacent metal anodes11are spaced by a gap and adjacent pixel units31are spaced by a gap. Each light-transmitting region23in the present region Z1communicates with the gap between corresponding metal anodes11and the gap between corresponding pixel units31. A projection of the gap between the pixel units31, in a direction from the semi-transparent cathode layer2to the metal anode layer1, overlaps or partially overlaps with the gap between the metal anodes11. A projection of the light-transmitting region23in a direction from the semi-transparent cathode layer2to the metal anode layer1falls within the gap between the metal anodes11and the gap between the pixel units31.

As such, the light-transmitting region23, the gap between the pixel units31, and the gap between the metal anodes11form an optical path channel. Light can enter the photosensitive component201through the light-transmitting region23, the gap between the pixel units31, and the gap between the metal anodes11in sequence, which such that the photosensitive component300can realize corresponding functions by sensing light to generate a corresponding photosensitive signal.

In an implementation, a size of a photosensitive surface of the photosensitive component201can be approximately the same as a size of the preset region Z1, and the light passing through all light-transmitting regions23of the preset region Z1can be received by the photosensitive component201.

In some implementations, the photosensitive component201includes at least one of a light sensor or a camera lens module.

In an implementation, the camera lens module may include a camera lens and an image sensor.

As illustrated inFIG. 10, the electronic device200further includes a processor202. The processor202is connected to the photosensitive component201and used to perform corresponding functions according to a light-sensing signal generated by the photosensitive component201.

In an implementation, when the photosensitive component201is a light sensor, it generates a corresponding light-sensing signal upon receiving external light. The processor202receives the light-sensing signal to determine an external ambient brightness, and can control to automatically adjust a display brightness of the display screen100.

When the photosensitive component201is a camera lens module, it receives external light to generate a corresponding image light-sensing signal, and the processor202receives the image light-sensing signal to perform imaging processing.

In some implementations, when there are two preset regions Z1, for example, as mentioned above, the preset regions Z1are respectively disposed at positions close to two opposite short sides of the display screen100. The electronic device200of the disclosure is a full-screen display screen, and thus a size of the display screen100is approximately the same as a size of an orthographic projection of the electronic device200on a plane where the display screen100is located. The two preset regions Z1are also respectively disposed at positions close to two opposite short sides of the electronic device200. Correspondingly, there are at least two photosensitive components300, which are disposed in the two preset regions Z1. In an implementation, the full-screen display screen has a screen-to-body ratio of 100%.

When the photosensitive component201is a light sensor, it can generate corresponding light-sensing signals at positions close to two opposite short sides of the electronic device200, so that more accurate detection of ambient brightness can be realized. The processor202can eventually determine the ambient brightness according to the light-sensing signals generated by the at least two photosensitive components300, and control and adjust the display brightness of the display screen100according to the eventually determined ambient brightness, and thus more accurate adjustment can be achieved.

When the photosensitive component201is a camera lens module, it can generate corresponding image light-sensing signals by respectively collecting light at positions close to the two opposite short sides of the electronic device200, which can realize wide-angle photography or depth photography. Specifically, the processor202can obtain a wide-angle image or a depth image according to the image light-sensing signals generated by the at least two photosensitive components300, and obtain more types of images to meet more needs of users.

In an implementation, the processor202may be a processor integrated with an image processor, and the like. Specifically, the processor202may be a central processing unit, a digital signal processor, a single-chip microcomputer, and the like.

The electronic device200can be an electronic device with a display screen and a photosensitive component, such as a mobile phone, a tablet computer, a digital camera, and the like.

Therefore, in this disclosure, in the preset region of the display screen100, the light-transmitting regions23are disposed in the semi-transparent cathode layer2to allow light to pass through the display screen100. When the display screen100is used in the electronic device200, photosensitive components201arranged on the inner side of the display screen100can operate normally without a non-display region reserved for holing, which significantly increases the screen-to-body ratio of the display screen100.
