Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] With the development of display technology, display panels with integrated light sensors have appeared on the market. By integrating light sensors, display panels can automatically detect the brightness of the surrounding environment and adjust the screen brightness. To ensure that the light sensor can sense the external ambient light, an opening is provided in the light shielding layer above the light sensor. However, the external ambient light will also be incident on the metal electrode of the light sensor and reflect, causing the metal electrode of the light sensor to be visible under certain strong light conditions, affecting the user experience. Summary of the Invention

[0003] In order to solve the above technical problems, the present application provides a display panel and a display device to reduce the visibility risk of metal electrodes in photosensors and improve user experience.

[0004] To achieve the above objectives, this application provides the following technical solutions:

[0005] In a first aspect of the present application, a display panel is provided, the display panel comprising a display area and a non-display area at least partially surrounding the display area;

[0006] The non-display area further includes a light-sensitive sensor, at least one light-sensitive sensor including n light-sensitive recognition units, where n is greater than or equal to 2 and n is an integer;

[0007] The non-display area further includes a first light shielding layer, the first light shielding layer includes m first openings, m≥2, and m is an integer;

[0008] Along the thickness direction of the display panel, at least one first opening exposes at least a portion of the light-sensitive recognition unit.

[0009] According to a second aspect of the present application, another display panel is provided, the display panel comprising a display area and a non-display area at least partially surrounding the display area;

[0010] The display panel includes a first substrate and a second substrate arranged opposite to each other;

[0011] The non-display area further includes a photosensor, which is located on a side of the first substrate close to the second substrate;

[0012] The non-display area further includes a first light shielding layer, the first light shielding layer is located on a side of the second substrate close to the first substrate, the first light shielding layer includes m first openings, m≥2, and m is an integer;

[0013] The width of the first opening is in the range of 10 μm to 50 μm, inclusive; the length of the first opening is in the range of 100 μm to 400 μm, inclusive;

[0014] Along the thickness direction of the display panel, the first opening exposes a portion of the light sensor.

[0015] In a third aspect of the present application, a display device is provided, which includes any one of the above-mentioned display panels.

[0016] Compared with the existing technology, the above technical solution has the following advantages:

[0017] The display panel and display device provided in the present application include a display area and a non-display area that at least partially surrounds the display area, wherein the non-display area is provided with a photosensitive sensor and a first light-shielding layer, wherein at least one photosensitive sensor is divided into n photosensitive identification units, n≥2, and n is an integer, and at the same time, m first openings are provided in the first light-shielding layer, m≥2, and m is an integer, and along the thickness direction of the display panel, at least one first opening exposes at least part of the photosensitive identification unit. In this way, on the basis of the photosensitive identification unit in the photosensitive sensor sensing the external ambient light through the first opening, not only is the area of ​​the photosensitive identification unit exposed by each first opening in the first light-shielding layer reduced, so that the reflection of the metal electrode in the photosensitive identification unit exposed by each first opening to the external ambient light is weakened, thereby reducing the visibility risk of the metal electrode in the photosensitive sensor and improving the user experience, but also the area of ​​the overall photosensitive identification area composed of the n photosensitive identification units in the photosensitive sensor can be guaranteed, thereby ensuring the photosensitivity performance of the photosensitive sensor.

[0018] Optionally, the width of the first opening in the first light-shielding layer can range from 10μm to 50μm, including the endpoint values; the length of the first opening can range from 100μm to 400μm, including the endpoint values; in this way, the reflection of external ambient light by the metal electrodes in the photosensitive sensors exposed by each first opening in the first light-shielding layer is not easily recognized by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensors and improving the user experience.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate and are merely used to describe the manner in which objects with the same attributes are distinguished in the embodiments of this application. In addition, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0038] Secondly, this application is described in detail with reference to schematic diagrams. When describing the embodiments of this application, for ease of illustration, the drawings depicting device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of this application. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0039] The embodiment of the present application provides a display panel 100, Figure 1 A schematic top view of a display panel 100 provided in an embodiment of the present application is shown. Figure 1 As shown, the display panel 100 includes a display area AA and a non-display area NA at least partially surrounding the display area AA. The non-display area NA includes a photosensor 110 .

[0040] Figure 2 FIG. 1 shows a schematic structural diagram of a non-display area where the light sensor 110 is located in a display panel 100 provided in an embodiment of the present application along the RR′ cross section. Figure 2 As shown, at least one photosensor 110 includes n photosensitivity recognition units 111, where n≥2 and n is an integer; at the same time, the non-display area NA also includes a first light-shielding layer 103, and the first light-shielding layer 103 includes m first openings K1, where m≥2 and m is an integer; along the thickness direction of the display panel, at least one first opening K1 exposes at least part of the photosensitivity recognition unit 111.

[0041] Optional, such as Figure 2 As shown, the display panel 100 includes a first substrate 101 and a second substrate 102 arranged opposite to each other, the photosensor 110 is located on the side of the first substrate 101 close to the second substrate 102, and the first light-shielding layer 103 is located on the side of the second substrate 102 close to the first substrate 101. However, the present application does not limit the specific film layer positions of the photosensor 110 and the first light-shielding layer 103, as long as the first opening K1 in the first light-shielding layer 103 can expose at least part of the photosensor identification unit 111.

[0042] As a comparison, Figure 3 A schematic cross-sectional structure diagram of a display panel integrated with a conventional light sensor 110 is shown. Figure 3 As shown, in the existing display panel integrated with the photosensor 110, the photosensor 110 has an overall continuous photosensor identification area CC, and the first light shielding layer 103 above the photosensor 110 has an overall continuous opening K0 to expose the overall continuous photosensor identification area CC of the photosensor 110, so as to facilitate the photosensor to sense and identify the external ambient light.

[0043] In the display panel provided in the embodiment of the present application, Figure 2 As shown, the opening corresponding to the photosensor 110 in the first light-shielding layer 103 is no longer an overall continuous opening K0, but m smaller first openings K1, which is equivalent to dividing the overall continuous opening K0 into m smaller mutually isolated first openings K1. As a result, the area of ​​the photosensor 110 exposed by each first opening K1 in the first light-shielding layer 103 is reduced, so that the reflection of the metal electrode in the photosensor identification area exposed by each first opening K1 to the external ambient light is weakened, thereby reducing the visibility risk of the metal electrode in the photosensor and improving the user experience.

[0044] However, when the area of ​​the entire light-sensitive recognition area CC of the light-sensitive sensor 110 is constant, if only m first openings K1 are provided in the first light-shielding layer 103, the first light-shielding layer 103 between the first openings K1 will block part of the light-sensitive recognition area, sacrificing the light-sensitive performance of the light-sensitive sensor 110. Based on this, in the display panel provided in the embodiment of the present application, Figure 2 As shown, not only are m first openings K1 provided in the first light-shielding layer 103, but the photosensitive sensor 110 is also divided into n photosensitive identification units 111. Along the thickness direction of the display panel, the first openings K1 expose at least a portion of the photosensitive identification units 111. In this way, while reducing the visibility risk of the metal electrodes in the photosensitive sensor, it is also possible to ensure that the area of ​​the overall photosensitive identification region composed of the photosensitive identification units 111 exposed by each first opening K1 is approximately equal to the area of ​​the overall photosensitive identification region CC of the photosensitive sensor 110, thereby ensuring the photosensitivity of the photosensitive sensor.

[0045] Optionally, m≤n, that is, the number of the first openings K1 provided in the first light shielding layer 103 is less than or equal to the number of the light-sensitive identification units 111 in the light-sensitive sensor 110. Thus, the first opening K1 in the first light shielding layer 103 exposes at least one light-sensitive identification unit 111 in the light-sensitive sensor 110.

[0046] Optional, such as Figure 2 and Figure 4 As shown, Figure 4 A schematic diagram of the top-down structure of a non-display area where a photosensitive sensor 110 is located in a display panel 100 provided in an embodiment of the present application is shown. It can be seen that m=n, that is, the first opening K1 in the first light-shielding layer 103 and the photosensitive identification unit 111 in the photosensitive sensor 110 are arranged in a one-to-one correspondence. In this way, the area of ​​the photosensitive identification unit 111 exposed by each first opening K1 is smaller, so that the metal electrode in the photosensitive identification unit 111 exposed by each first opening K1 reflects the external ambient light more weakly, further reducing the visibility risk of the metal electrode in the photosensitive sensor and improving the user experience.

[0047] Another option, such as Figure 5 and Figure 6 As shown, Figure 5 FIG. 1 shows a schematic structural diagram of a non-display area where a light sensor 110 is located in another display panel 100 provided in an embodiment of the present application along a cross section RR′. Figure 6FIG. 0 shows a top view structural schematic diagram of the non-display area where the photosensitive sensor 110 is located in another display panel 100 provided by an embodiment of the present application. It can be seen that m < n, that is, the first opening K1 in the first light-shielding layer 103 can expose two or more photosensitive recognition units 111 in the photosensitive sensor 110. Thus, while reducing the visibility risk of the metal electrodes in the photosensitive sensor, the number of the first openings K1 in the first light-shielding layer 103 can be reduced.

[0048] In summary, it can be m ≤ n, that is, the number of the first openings K1 provided in the first light-shielding layer 103 is less than or equal to the number of the photosensitive recognition units 111 in the photosensitive sensor 110. Thus, while reducing the visibility risk of the metal electrodes in the photosensitive sensor, each of the first openings K1 in the first light-shielding layer 103 can completely expose each of the photosensitive recognition units 111 in the photosensitive sensor 110, ensuring the photosensitive performance of the photosensitive sensor, and the number of the first openings K1 in the first light-shielding layer 103 is relatively small.

[0049] Specifically, it can be 2 ≤ n ≤ 10, 2 ≤ m ≤ 10, that is, the photosensitive sensor 110 is divided into 2 - 10 photosensitive recognition units 111, and 2 - 10 first openings K1 are provided in the first light-shielding layer 103, which is specifically determined according to the situation.

[0050] It should be noted that along the thickness direction of the display panel, the first opening K1 exposes at least part of the photosensitive recognition units 111, that is, along the thickness direction of the display panel, the first opening K1 can completely expose the photosensitive recognition units 111 or expose part of the photosensitive recognition units 111.

[0051] It can be understood that when the first opening K1 completely exposes the photosensitive recognition units 111, as Figure 2 、 Figure 4-Figure 6 shown, the external ambient light can enter the photosensitive recognition units 111 through the first opening K1 and be sensed and recognized by the photosensitive recognition units 111.

[0052] Specifically, as Figure 2 、 Figure 4-Figure 6 shown, the orthographic projection of the photosensitive recognition units 111 on the first substrate 101 is located within the orthographic projection of the first opening K1 on the first substrate 101. Thus, along the thickness direction of the display panel, the first opening K1 can completely expose the photosensitive recognition units 111, thereby improving the photosensitive recognition effect of the photosensitive recognition units 111 on the external ambient light incident through the first opening K1, and further improving the photosensitive recognition effect of the photosensitive sensor 110 on the external ambient light.

[0053] When the first opening K1 exposes part of the photosensitive recognition units 111, as Figure 7 shown, Figure 7A structural schematic diagram of the non-display area where the photosensitive sensor 110 is located in another display panel 100 provided in an embodiment of the present application is shown along the RR' section. Since the external ambient light incident through the first opening K1 has a certain illumination range and is not completely limited to the photosensitive recognition area directly opposite the first opening K1, the photosensitive recognition effect of the photosensitive recognition unit 111 can be guaranteed as long as the photosensitive recognition unit 111 is located within the illumination range of the external ambient light passing through the first opening K1. At this time, the first opening K1 is allowed to expose part of the photosensitive recognition unit 111, that is, the photosensitive recognition unit 111 and the first light-shielding layer 103 are allowed to partially overlap in the thickness direction of the display panel.

[0054] In the embodiment of the present application, the photosensitive sensor 110 includes n photosensitive identification units 111, and the first opening K1 exposes at least part of the photosensitive identification unit 111 along the thickness direction of the display panel. That is, along the thickness direction of the display panel, the first opening K1 exposes part of the photosensitive sensor 110.

[0055] Regarding the size setting of the first opening K1 in the first light shielding layer 103, it is optional, such as Figure 4 and Figure 6 As shown, the width a of the first opening K1 in the first light-shielding layer 103 ranges from 10 μm to 50 μm, including the endpoint values; the length b of the first opening K1 ranges from 100 μm to 400 μm, including the endpoint values; with such a setting, the reflection of the external ambient light by the metal electrodes in the photosensitive sensors 110 exposed by each first opening K1 in the first light-shielding layer 103 is not easily recognized by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensors and improving the user experience.

[0056] Further optional, such as Figure 4 and Figure 6 As shown, the distance c between two adjacent first openings K1 in the first light-shielding layer 103 has a value range of 1000μm-3000μm, including the endpoint values; with such a setting, the distance c between two adjacent first openings K1 in the first light-shielding layer 103 is greater than the length b of the first opening K1, and greater than the width a of the first opening K1. The reflection of external ambient light by the metal electrodes in the photosensitive identification unit 111 exposed by the two adjacent first openings K1 is less likely to be recognized by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensor 110 and improving the user experience.

[0057] Regarding the size setting of the light-sensitive recognition unit 111 in the light-sensitive sensor 110, it is optional, such as Figure 4As shown, m = n. That is, the first openings K1 in the first light-shielding layer 103 and the photosensitive recognition units 111 in the photosensitive sensor 110 are arranged in one-to-one correspondence. At this time, the size of the photosensitive recognition unit 111 can be set according to the size of the first opening K1. The value range of the width f of the photosensitive recognition unit 111 can be set to be 10 μm - 50 μm, including the end values; the value range of the length d of the photosensitive recognition unit 111 can be set to be 100 μm - 400 μm, including the end values. With such a setting, the reflection of the metal electrodes in each photosensitive recognition unit 111 in the photosensitive sensor 110 to the external ambient light is not easily recognizable by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensor and improving the user experience.

[0058] Further optionally, the value range of the distance e1 between two adjacent photosensitive recognition units 111 is 1000 μm - 3000 μm, including the end values. With such a setting, the distance e1 between two adjacent photosensitive recognition units 111 in the photosensitive sensor 110 is greater than the length d of the photosensitive recognition unit 111 and greater than the width f of the photosensitive recognition unit 111. The reflection of the metal electrodes in two adjacent photosensitive recognition units 111 to the external ambient light is even less easily recognizable by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensor 110 and improving the user experience.

[0059] Another option is, as Figure 6 shown, m < n. That is, the first openings K1 in the first light-shielding layer 103 can expose at least two photosensitive recognition units 111 in the photosensitive sensor 110. At this time, the size of the photosensitive recognition unit 111 is smaller than the size of the first opening K1. The value range of the distance e2 between two adjacent photosensitive recognition units 111 exposed by the first opening K1 can be set to be 10 μm - 100 μm, including the end values. With such a setting, the risk that the reflection of the metal electrodes in two adjacent photosensitive recognition units 111 exposed by the same first opening K1 to the external ambient light is recognized by the human eye is minimized, thereby reducing the visibility risk of the metal electrodes in the photosensitive sensor 110 and improving the user experience.

[0060] In practical applications, the display panel 100 may be a liquid crystal display panel. The display panel 100 includes a first substrate 101 and a second substrate 102 disposed opposite each other. Both the first substrate 101 and the second substrate 102 extend through the display area AA to the non-display area NA. To achieve color display, the first substrate 101 may be an array substrate, and the second substrate 102 may be a color filter substrate. In the display area AA, a liquid crystal layer is disposed between the first and second substrates 101, 102. Liquid crystal molecules in the liquid crystal layer are deflected by an electric field, causing light emitted by the backlight module to be emitted from the second substrate 102 side under the influence of the liquid crystal molecules, thereby achieving display functionality. In the non-display area NA, no liquid crystal layer is disposed between the first and second substrates 101, but rather an air layer. This allows ambient light entering through the second substrate 102 and the first opening K1 to bypass the liquid crystal molecules and directly strike the photosensor 110 on the first substrate 101, where it is detected and recognized.

[0061] Optionally, in some embodiments of the present application, such as Figure 2 、 Figure 4-Figure 7 As shown, the non-display area NA further includes a semiconductor layer 104, which is located on the side of the first substrate 101 close to the second substrate 102. The semiconductor layer 104 includes n mutually isolated first semiconductor portions B10, and the light-sensitive recognition unit 111 includes the first semiconductor portion B10.

[0062] For ease of understanding, Figure 8 FIG. 1 shows a schematic top view of a light sensor 110 in a display panel 100 provided in an embodiment of the present application. Figure 8 As shown, in the photosensor 110, the photosensor identification unit 111 includes a first semiconductor portion B10, and the photosensor identification unit 111 includes a plurality of photosensor units 10; the first semiconductor portion B10 extends along a first direction X, and the first semiconductor portion B10 includes a plurality of first semiconductor sub-portions B11 connected in sequence along the first direction X, and the first direction X is parallel to the plane where the display panel is located; the photosensor unit 10 includes a first semiconductor sub-portion B11, a first source electrode S1 and a first drain electrode D1 electrically connected to the first semiconductor sub-portion B11.

[0063] Optional, such as Figure 9a As shown, Figure 9a A schematic diagram of the cross-sectional structure of a photosensitive unit 10 is shown, in which the first semiconductor division B11 of the photosensitive unit 10 is an amorphous silicon (a-Si) semiconductor layer, that is, the semiconductor layer 104 is an amorphous silicon semiconductor layer. At this time, in the photosensitive unit 10, the first source electrode S1 is directly overlapped with the first semiconductor division B11, and the first drain electrode D1 is directly overlapped with the first semiconductor division B11.

[0064] Another option, such as Figure 9b As shown, Figure 9b A schematic diagram of the cross-sectional structure of another photosensitive unit 10 is shown. The first semiconductor division B11 of this photosensitive unit 10 is a low-temperature polycrystalline silicon (LTPS) semiconductor layer, that is, the semiconductor layer 104 is a low-temperature polycrystalline silicon semiconductor layer. At this time, in the photosensitive unit 10, the first source electrode S1 is electrically connected to the first semiconductor division B11 through a via, and the first drain electrode D1 is also electrically connected to the first semiconductor division B11 through a via; and the photosensitive unit 10 also includes a gate G01.

[0065] And, as Figure 1 As shown, the display panel 100 further includes a reference device 120, and is combined with Figure 9a and Figure 9b As shown, the reference device 120 includes a reference transistor 20. The structure of the reference transistor 20 is the same as that of the photosensitive unit 10. The reference transistor 20 includes a second semiconductor portion B20, a second source electrode S2 electrically connected to the second semiconductor portion B20, and a second drain electrode D2. The second semiconductor portion B20 is provided in the same layer as the first semiconductor portion B10, and the second source electrode S2 and the second drain electrode D2 are provided in the same layer as the first source electrode S1 and the first drain electrode D1. Similarly, the second semiconductor portion B20 of the reference transistor 20 can be an amorphous silicon semiconductor layer or a low-temperature polycrystalline silicon semiconductor layer. When the second semiconductor portion B20 of the reference transistor 20 is a low-temperature polycrystalline silicon semiconductor layer, the reference transistor 20 also includes a gate G02.

[0066] It can be understood that the photosensitive unit 10 outputs a photosensitive current in response to the input signal and the illumination of the first semiconductor division B11 by the external incident light, so that the photosensitive sensor 110 outputs a photosensitive current; the reference transistor 20 outputs a reference current in response to the input signal, so that the reference device 120 outputs a reference current; thus, the display panel 100 can obtain the brightness of the external incident light based on the photosensitive current output by the photosensitive sensor 110 and the reference current output by the reference device 120, for example, based on the difference between the photosensitive current and the reference current, to realize the detection of the brightness of the external ambient light. Figure 3 A reference device 120 is also shown in the conventional display panel integrated with the photosensor 110 .

[0067] Combine Figure 8 、 Figure 9a and Figure 9bAs shown, the first source electrode S1 and the first drain electrode D1 of the photosensitive unit 10 are located on the side of the first semiconductor part B10 away from the first substrate 101, and the first source electrode S1 and the first drain electrode D1 extend along the second direction Y, the second direction Y is parallel to the plane where the display panel is located, and the second direction Y intersects with the first direction X; along the first direction X, the first source electrode S1 and the first drain electrode D1 are arranged alternately; it can be understood that the multiple photosensitive units 10 in the photosensitive identification unit 111 are connected in series because the first semiconductor divisions B11 are connected in sequence, that is, the photosensitive identification unit 111 includes multiple photosensitive units 10 connected in series.

[0068] like Figure 8 As shown, the display panel 100 also includes a first source electrode line S10 and a first drain electrode line D10. Each first source electrode S1 is electrically connected to the first source electrode line S10, and each first drain electrode D1 is electrically connected to the first drain electrode line D10. In this way, n photosensitive identification units 111 in the photosensitive sensor 110 are connected in series to output a photosensitive current.

[0069] It can be understood from the above description that the first source electrode S1 and the first drain electrode D1 of the multiple photosensitive units 10 in the photosensitive identification unit 111 are the metal electrodes exposed by the first opening K1. In the present application, the photosensitive sensor 110 is divided into n photosensitive identification units 111, and m first openings K1 are opened in the first light-shielding layer 103. The first opening K1 exposes at least part of the photosensitive identification unit 111. Then, the number of the first source electrode S1 and the first drain electrode D1 in the photosensitive identification unit 111 exposed by each first opening K1 is reduced, and the reflection of the external ambient light is weakened, thereby reducing the visibility risk of the first source electrode S1 and the first drain electrode D1 in each photosensitive identification unit 111.

[0070] It should also be understood that in this application, dividing the photosensor 110 into n photosensor recognition units 111 essentially means dividing the semiconductor layer of the photosensor 110 into n mutually isolated first semiconductor portions B10. The first semiconductor portions B10 correspond one-to-one to the photosensor recognition units 111, and the n photosensor recognition units 111 are also mutually isolated. In some figures of this application, the first semiconductor portion B10 is primarily used to represent the photosensor recognition units 111.

[0071] Optionally, in some embodiments of the present application, such as Figure 4 and Figure 6 As shown, n light-sensitive recognition units 111 are arranged along the first direction X, and m first openings K1 are arranged along the first direction X, and the first direction X is parallel to the plane where the display panel is located; in this way, combined with Figure 1As shown, although the photosensor 110 is divided into n photosensitivity recognition units 111, since the n photosensitivity recognition units 111 are arranged along the first direction X, and the m first openings K1 corresponding to the n photosensitivity recognition units 111 are arranged along the first direction X, that is, the main increase is the length of the photosensor 110 along the first direction X and the distribution of the first openings K1 along the first direction X. Therefore, as long as the photosensor 110 is arranged in the non-display area of ​​the display panel 100 extending along the first direction X, the frame area of ​​the display panel 100 will not be increased.

[0072] It is understandable that if Figure 1 As shown, the light sensor 110 can be located at the upper frame or the lower frame of the display panel 100. In this case, the first direction X can be the horizontal direction of the display panel 100, and the second direction Y can be the vertical direction of the display panel 100. Of course, the light sensor 110 can also be located at the left frame or the right frame of the display panel 100. In this case, the first direction X can be the vertical direction of the display panel 100, and the second direction Y can be the horizontal direction of the display panel 100.

[0073] Further optionally, in some embodiments of the present application, such as Figure 4 and Figure 6 As shown, the geometric centers of the n light-sensitive recognition units 111 are located on a virtual line L1 extending along the first direction X; the geometric centers of the m first openings K1 are located on a virtual line L2 extending along the first direction X. The virtual line L1 and the virtual line L2 can be the same virtual line, but this is not a limitation in this application. The virtual lines L1 and L2 can also be parallel to each other. This arrangement only increases the length of the light-sensitive sensor 110 along the first direction X and the distribution of the first openings K1 along the first direction X, without affecting the width occupied by the light-sensitive sensor 110 and the first openings K1 along the second direction Y, thereby facilitating a narrow bezel on the display panel.

[0074] Alternatively, in some embodiments of the present application, Figure 10 As shown, Figure 10 FIG2 shows a top view of the non-display area of ​​another display panel 100 provided by an embodiment of the present application, in which the light-sensitive sensor 110 is located. It can be seen that the n light-sensitive recognition units 111 are also arranged as a whole along the first direction X, and the m first openings K1 are also arranged as a whole along the first direction X. The first direction X is parallel to the plane where the display panel is located. Figure 4 and Figure 6 The arrangement of the light-sensing recognition unit 111 and the first opening K1 shown is different in that: Figure 10Among the n light-sensitive recognition units 111 shown, the geometric centers of at least two light-sensitive recognition units 111 are staggered along a second direction Y, the second direction Y is parallel to the plane where the display panel is located, and the second direction Y intersects the first direction X; and Figure 10 Among the n first openings K1 shown, the geometric centers of at least two first openings K1 are staggered along the second direction Y; with such a setting, the reflected light of the external ambient light by the metal electrodes in the photosensitive identification unit 111 staggered along the second direction Y is less likely to be recognized by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensor 110 and improving the user experience.

[0075] Further optionally, in some embodiments of the present application, such as Figure 10 As shown, m=n, that is, the first openings K1 in the first light shielding layer 103 and the light-sensitive identification units 111 in the light-sensitive sensor 110 are arranged in a one-to-one correspondence; and, among the n light-sensitive identification units 111, the geometric centers of the light-sensitive identification units 111 at odd positions along the first direction X are located on a virtual straight line L3 extending along the first direction X, and the geometric centers of the light-sensitive identification units 111 at even positions along the first direction X are located on another virtual straight line L4 extending along the first direction X; among the m first openings K1, the geometric centers of the first openings K1 at odd positions along the first direction X are located on a virtual straight line L3 extending along the first direction X, and the geometric centers of the light-sensitive identification units 111 at even positions along the first direction X are located on another virtual straight line L4 extending along the first direction X. The geometric center of each first opening K1 is located on a virtual straight line L5 extending along the first direction X, and the geometric center of each first opening K1 at an even-numbered position along the first direction X is located on another virtual straight line L6 extending along the first direction X. The virtual straight line L3 and the virtual straight line L5 may be the same virtual straight line, but this application does not limit this. The virtual straight line L3 and the virtual straight line L5 may also be parallel to each other, but they are different virtual straight lines. Similarly, the virtual straight line L4 and the virtual straight line L6 may be the same virtual straight line, but this application does not limit this. The virtual straight line L4 and the virtual straight line L6 may also be parallel to each other, but they are different virtual straight lines. This arrangement not only further reduces the risk of visibility of the metal electrodes in the light sensor 110 by staggering the light-sensitive identification units 111 and the first opening K1 along the second direction Y, but also minimizes the increase in the width occupied by the light sensor 110 and the first opening K1 along the second direction Y, thereby facilitating a narrow bezel on the display panel.

[0076] On the basis that the n light-sensitive identification units 111 in the light-sensitive sensor 110 are arranged along the first direction X as a whole, and the m first openings K1 in the first light-shielding layer 103 are also arranged along the first direction X as a whole, the size setting of the light-sensitive identification units 111 in the light-sensitive sensor 110 is optional, in some embodiments of the present application, such as Figure 4 、 Figure 6 and Figure 10As shown, the distance c between two adjacent first openings K1 along the first direction X is greater than the length b of the first opening K1 along the first direction X; with such a setting, the reflection of external ambient light by the metal electrodes in the photosensitive identification unit 111 exposed by the two adjacent first openings K1 is less likely to be recognized by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensor 110 and improving the user experience.

[0077] Further optionally, in some embodiments of the present application, the distance c between two adjacent first openings K1 along the first direction X is in the range of 1000 μm to 3000 μm, including the endpoint values; the length b of the first opening K1 along the first direction X is in the range of 100 μm to 400 μm, including the endpoint values; in this way, the distance c between two adjacent first openings K1 along the first direction X is significantly greater than the length b of the first opening K1 along the first direction X, which can further reduce the visibility risk of the metal electrode in the photosensitive sensor 110 and improve the user experience.

[0078] On the basis that the n light-sensitive recognition units 111 in the light-sensitive sensor 110 are arranged along the first direction X as a whole, and the m first openings K1 in the first light-shielding layer 103 are also arranged along the first direction X as a whole, optionally, in some embodiments of the present application, such as Figure 4 、 Figure 6 and Figure 10 As shown, the width a of the first opening K1 along the second direction Y ranges from 10 μm to 50 μm, including the end values. This setting minimizes the impact on the width occupied by the photosensitive sensor 110 and the first opening K1 along the second direction Y, which is beneficial to achieving a narrow frame of the display panel.

[0079] Regarding the size setting of the light-sensitive identification unit 111 in the light-sensitive sensor 110, on the basis that the n light-sensitive identification units 111 in the light-sensitive sensor 110 are arranged along the first direction X as a whole, and the m first openings K1 in the first light-shielding layer 103 are also arranged along the first direction X as a whole, optionally, in some embodiments of the present application, such as Figure 4 and Figure 10 As shown, the distance e1 between two adjacent photosensitive identification units 111 along the first direction X is greater than the length d of the photosensitive identification unit 111 along the first direction X; with such a setting, the reflection of external ambient light by the metal electrodes in the two adjacent photosensitive identification units 111 is less likely to be recognized by the human eye, thereby further reducing the visibility risk of the metal electrodes in the photosensitive sensor 110 and improving the user experience.

[0080] Further optionally, in some embodiments of the present application, such as Figure 4 and Figure 10As shown, m = n, that is, the first openings K1 in the first light-shielding layer 103 and the photosensitive recognition units 111 in the photosensitive sensor 110 are arranged in one-to-one correspondence. At this time, the size of the photosensitive recognition unit 111 can be set according to the size of the first opening K1. The value range of the distance e1 between two adjacent photosensitive recognition units 111 along the first direction X can be set to 1000 μm - 3000 μm, including the end values; the value range of the length d of the photosensitive recognition unit 111 along the first direction X is 100 μm - 400 μm, including the end values; with such a setting, the distance e between two adjacent photosensitive recognition units 111 along the first direction X is significantly greater than the length d of the photosensitive recognition unit 111 along the first direction X, which can further reduce the visibility risk of the metal electrodes in the photosensitive sensor 110 and improve the user experience.

[0081] Further optionally, in some embodiments of the present application, such as Figure 4 and Figure 10 As shown, the value range of the width f of the photosensitive recognition unit 111 along the second direction Y is 10 μm - 50 μm, including the end values; with such a setting, it does not affect the width occupied by the photosensitive sensor 110 and the first opening K1 along the second direction Y as much as possible, which is beneficial to realizing a narrow border of the display panel.

[0082] Another further optionally, in some embodiments of the present application, such as Figure 6 As shown, m < n, that is, the first openings K1 in the first light-shielding layer 103 can expose at least two photosensitive recognition units 111 in the photosensitive sensor 110. At this time, the size of the photosensitive recognition unit 111 is smaller than the size of the first opening K1. The value range of the distance e2 between two adjacent photosensitive recognition units 111 exposed by the first opening K1 can be set to 10 μm - 100 μm, including the end values. With such a setting, the risk that the reflection of the metal electrodes in two adjacent photosensitive recognition units 111 exposed by the same first opening K1 to the external ambient light is recognized by the human eye is minimized, thereby reducing the visibility risk of the metal electrodes in the photosensitive sensor 110 and improving the user experience.

[0083] Optionally, in some embodiments of the present application, such as Figure 2 、 Figure 5 and Figure 7 As shown, the non-display area NA of the display panel 100 may further include a second light-shielding layer 105. The second light-shielding layer 105 is located on the side of the second substrate 102 away from the first substrate 101. The second light-shielding layer 105 includes a second opening K2; along the thickness direction of the display panel, the second opening K2 exposes the photosensitive sensor 110. Optionally, along the thickness direction of the display panel, the second opening K2 exposes each of the first openings K1, so as to facilitate the second opening K2 to expose the photosensitive sensor 110, specifically exposing each photosensitive recognition unit 111 of the photosensitive sensor 110. Figure 3 The conventional display panel integrated with the photosensor 110 also shows the second light shielding layer 105 and the second opening K2 thereof.

[0084] contrast Figure 3 The conventional display panel shown and Figure 2 、 Figure 5 as well as Figure 7 As shown in the display panel of the embodiment of the present application, it can be seen that since the light sensor 110 is divided into n light-sensitive identification units 111 in the display panel of the embodiment of the present application, the overall length of the light sensor 110 is longer, and the second opening K2 in the second light shielding layer 105 needs to expose the light sensor 110, therefore, the size of the second opening K2 in the second light shielding layer 105 needs to be correspondingly larger. Figure 2 、 Figure 5 and Figure 7 As shown, the length of the second opening K2 ranges from 5mm to 2cm, including the endpoint values; the width of the second opening K2 ranges from 1mm to 5mm, including the endpoint values; so that the second opening K2 exposes the photosensitive sensor 110, ensuring the photosensitive sensor 110's photosensitivity and recognition effect to the external ambient light.

[0085] Optionally, in some embodiments of the present application, such as Figure 11 As shown, Figure 11 A schematic diagram of the structure of the non-display area where the photosensor 110 is located in another embodiment of the display panel 100 provided by the present application is shown along the RR' cross section. It can be seen that the first opening K1 in the first light-shielding layer 103 can be filled with a color resist 106. In this configuration, because the color resist allows some light to pass through and filters out some light, the color resist 106 can be used to reduce the emission of reflected light from the metal electrode in the photosensor identification unit 111 exposed by the first opening K1, thereby further reducing the visibility risk of the metal electrode in the photosensor 110 and improving the user experience. However, the first opening K1 is filled with the color resist 106, so that when the external ambient light passes through the first opening K1, it will also be partially filtered by the color resist 106. As a result, the external ambient light reaching the photosensor identification unit 111 of the photosensor 110 will be relatively weak. In order to avoid affecting the sensing and recognition effect of the light-sensitive recognition unit 111 of the light-sensitive sensor 110 on the external ambient light, the driving of the light-sensitive sensor 110 can be appropriately adjusted to ensure the sensing and recognition effect of the light-sensitive recognition unit 111 of the light-sensitive sensor 110 on the external ambient light.

[0086] Furthermore, in some embodiments of the present application, color resist 106 is a green color resist, which allows green light to pass through. Since green color resist has a relatively high transmittance for green light, setting color resist 106 as a green color resist can enhance the visual effect and improve the performance of light sensor 110 by taking advantage of the fact that light sensor 110 is more sensitive to green wavelengths of light than to red and blue wavelengths of light.

[0087] Of course, in the present application, the color resist 106 is not limited to the green color resist, and may also be other color resists such as red color resist and blue color resist.

[0088] Optionally, in some embodiments of the present application, such as Figure 2 、 Figure 5 、 Figure 7 and Figure 11 As shown, the photosensor 110 further includes a first gate G1 , which is located on a side of the semiconductor layer 104 close to the first substrate 101 ; Figure 12 A top view schematic diagram of another photosensitive sensor 110 in a display panel 100 provided in an embodiment of the present application is further shown. Figure 12 As shown, along the thickness direction of the display panel, the first gate G1 blocks the first semiconductor portion B10; such a configuration can prevent light from one side of the first substrate 101 from irradiating the first semiconductor portion B10, thereby improving the detection accuracy of the photosensor 110 for external ambient light.

[0089] in addition, Figure 9a and Figure 9b The first gate G1 is also shown, and combined with Figure 1 、 Figure 9a and Figure 9b As shown, a second gate G2 is provided on the side of the second semiconductor portion B20 of the reference transistor 20 of the reference device 120 close to the first substrate 101. The second gate G2 is provided on the same layer as the first gate G1. Along the thickness direction of the display panel, the second gate G2 blocks the second semiconductor portion B20. Figure 3 The conventional display panel integrated with the photosensor 110 also shows a first gate G1 and a second gate G2 .

[0090] It should be noted that if Figure 9a As shown, when the first semiconductor portion B11 of the photosensitive unit 10 of the photosensitive sensor 110 and the second semiconductor portion B20 of the reference transistor 20 of the reference device 120 are both amorphous silicon semiconductor layers, the first gate G1 of the photosensitive unit 10 close to the first substrate 101 and the second gate G2 of the reference transistor 20 close to the first substrate 101 mainly play the role of shielding the corresponding semiconductor portions. Figure 9bAs shown, when the first semiconductor division B11 of the photosensitive unit 10 of the photosensitive sensor 110 and the second semiconductor portion B20 of the reference transistor 20 of the reference device 120 are both low-temperature polycrystalline silicon semiconductor layers, in one case, the first gate G1 and the second gate G2 are insulating layers that shield the corresponding semiconductor portions; in another case, the first gate G1 and the gate G01 and the second gate G2 and the gate G02 respectively constitute a double-gate structure, that is, the first semiconductor division B11 of the photosensitive unit 10 of the photosensitive sensor 110 and the reference transistor 20 of the reference device 120 are both double-gate structures. Of course, the first gate G1 and the second gate G2 also play the role of shielding the corresponding semiconductor portions.

[0091] exist Figure 2 、 Figure 5 、 Figure 7 and Figure 11 As shown, the display panel provided in the embodiment of the present application further includes a polarizer 107 located on the side of the second substrate 102 facing away from the first substrate 101. Ambient light can be converted into polarized light after passing through the polarizer 107. In addition, there is also a polarizer on the side of the first substrate 101, which is not shown in the figure.

[0092] The embodiment of the present application further provides a display device, Figure 13 FIG. 1 shows a schematic diagram of a top view of a display device provided in an embodiment of the present application. Figure 13 As shown, the display device 200 includes a display panel 100, which is the display panel provided by any of the above embodiments. Since the display panel 100 has been described in detail in the above embodiments, it will not be repeated here.

[0093] The display device 200 can be any electronic device with a display function, such as a touch screen display, a mobile phone, a tablet computer, a laptop computer, an e-reader, or a television.
