[0036] The above is the core idea of the present invention. Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Figure 2A schematic structural diagram of a display panel provided by an embodiment of the present invention Figure 3 A schematic structural diagram of a light sensing recognition area provided by an embodiment of the present invention Figure 4 is Figure 3 a schematic cross-sectional structure diagram along the section line AA', as Figure 2 , Figure 3 and Figure 4 shown. The display panel 100 includes a display area 101 and a non-display area 102 disposed around the display area 101. The non-display area 102 includes a first substrate 103 and a second substrate 104 disposed opposite to each other, and an air layer is formed between the first substrate 103 and the second substrate 104. The non-display area 102 further includes a light sensing recognition area 105, and the light sensing recognition area 105 includes a light sensing recognition unit 106, and the light sensing recognition unit 106 is located on one side of the first substrate 103 close to the second substrate 104. A first light shielding layer 107 is disposed on one side of the second substrate 104 close to the first substrate 103, and an opening setting area 108 is provided on the first light shielding layer 107, and at least two openings 109 are spaced apart from each other in the opening setting area 108.

[0038] Among them, the display panel 100 includes a display area 101 and a non-display area 102 disposed around the display area 101. The display panel 100 is a liquid crystal display panel 100. The display panel 100 includes a first substrate 103 and a second substrate 104 disposed opposite to each other. Both the first substrate 103 and the second substrate 104 extend to the non-display area 102 through the display area 101. To achieve color display, the first substrate 103 can be an array substrate, and the second substrate 104 can be a color filter substrate. In the display area 101, a liquid crystal layer is disposed between the first substrate 103 and the second substrate 104. The liquid crystal molecules in the liquid crystal layer deflect under the action of an electric field, so that the light emitted by the backlight module (not shown in the figure) exits from the side of the second substrate 104 under the action of the liquid crystal molecules, and the display panel 100 realizes the display function. In the non-display area 102, no liquid crystal layer is disposed between the first substrate 103 and the second substrate 104, and an air layer is formed, so that the external ambient light incident through the second substrate 104 directly enters the second substrate 104 without passing through the liquid crystal molecules. The non-display area 102 further includes a light sensing recognition area 105. The light sensing recognition area 105 includes a light sensing recognition unit 106. The light sensing recognition unit 106 is disposed on the first glass substrate 1031 in the first substrate 103 and is located on the side of the first glass substrate 1031 close to the second substrate 104, which can effectively reduce costs. The light sensing recognition unit 106 receives the external ambient light incident through the second substrate 104. This external ambient light directly enters the light sensing recognition unit 106 without passing through the liquid crystal molecules, which is beneficial to improving the recognition accuracy of the light sensing recognition unit 106. Furthermore, the light sensing recognition unit 106 transmits the recognition structure to the control unit of the display panel 100, thereby realizing the adjustment of the display brightness of the display panel 100 and ensuring the user experience. The second substrate 104 in the non-display area 102 includes a second glass substrate 1041. A first light-shielding layer 107 disposed in a whole layer is provided on the side of the second glass substrate close to the first substrate 103. The first light-shielding layer 107 is provided with an opening setting area 108. At least two openings 109 spaced apart from each other are provided in the opening setting area 108. The openings 109 are used for the incident of external ambient light to ensure the recognition effect of the light sensing recognition unit 106. The number of openings 109 provided in the opening setting area 108 can be selected according to actual design requirements, and no specific limitation is made in the embodiments of the present invention. Figure 2 Exemplarily, the case where two openings 109 are provided in the opening setting area 108 is taken as an example for display. The second substrate 104 further includes a polarizer 1042 located on the side of the second glass substrate 1041 away from the first light-shielding layer 107. The external ambient light becomes polarized light after passing through the polarizer. Since two openings 109 are provided in the opening setting area 108, polarized light with the same frequency and the same phase undergoes double-slit interference after passing through the opening setting area 108, and the light after interference can enter the light sensing recognition unit 106. The setting position of the light sensing recognition unit 106 can be selected according to actual design requirements.Figure 2 Taking the example where there is an opening 109 overlapping with the light sensing recognition unit 106 along the thickness direction X of the display panel 100 as shown in the figure, the light sensing recognition unit 106 can be set within the range where the brightest fringe of the interfering light appears, ensuring that the brightest light is recognized by the light sensing recognition unit 106, guaranteeing the recognition effect of the light sensing recognition unit 106, and further ensuring the subsequent brightness adjustment effect of the display panel 100. At the same time, a plurality of openings 109 are provided in the opening setting area 108. On the premise that the external ambient light can enter the light sensing recognition unit 106, since the first light shielding layer 107 between adjacent openings 109 in the opening setting area 108 plays a certain blocking role, the light reflected by the light sensing recognition unit 106 or other metal traces on one side of the first substrate 103 can be effectively reduced from exiting, improving the user experience.

[0039] In the embodiment of the present invention, by providing a plurality of openings on the first light shielding layer on the side of the second substrate close to the first substrate in the non-display area, and at the same time providing a light sensing recognition unit on the side of the first substrate close to the second substrate, it is ensured that the light sensing recognition unit can receive the external ambient light, guaranteeing the recognition effect. At the same time, the design of a plurality of openings in the opening setting area of the first light shielding layer can reduce the probability of the light reflected by the light sensing recognition unit from exiting, ensuring the user experience.

[0040] Optionally, Figure 5 This is a schematic cross-sectional structure diagram of a light sensing recognition area provided by an embodiment of the present invention. As Figure 5 shown, along the thickness direction X of the display panel 100, the opening 109 and the light sensing recognition unit 106 at least partially overlap.

[0041] Among them, exemplarily, two openings 109 are provided in the opening setting area 108 of the first light shielding layer 107. Along the thickness direction X of the display panel 100, as Figure 4 shown, the light sensing recognition unit 106 partially overlaps with one opening 109 in the opening setting area 108, or as Figure 5 shown, the light sensing recognition unit 106 partially overlaps with both openings 109 in the opening setting area 108. The specific setting method can be set according to actual design requirements, ensuring that the incident external ambient light can enter the light sensing recognition unit 106 through the opening 109, guaranteeing that the light sensing recognition unit 106 can recognize the external ambient light accurately, and further realizing that the brightness of the display panel 100 is adjusted accordingly with the change of the external environment.

[0042] Optionally, Figure 6 This is another schematic cross-sectional structure diagram of a light sensing recognition area provided by an embodiment of the present invention. As Figure 6As shown, in any plane parallel to the vertical light-emitting direction of the display panel 100, along the thickness direction X of the display panel 100, the central axis L1 of the opening setting area 108 overlaps at least partially with the light-sensing recognition unit 106.

[0043] Among them, for example, when two openings 109 are provided in the opening setting area 108, the ambient light incident through the polarizer 1042 on one side of the second substrate 104 becomes polarized light. The light rays with the same phase will undergo double-slit interference after passing through the openings 109, and the light rays will be superimposed on each other, resulting in bright and dark fringes on one side of the first substrate 103. To ensure that the light rays can fall on the light-sensing recognition unit 106 located on one side of the first substrate 103, it is controlled that along the thickness direction X of the display panel 100, the central axis L1 of the opening setting area 108 overlaps with the light-sensing recognition unit 106, so that the light-sensing recognition unit 106 can receive the external ambient light, and then the recognition of the light rays can be realized. At the same time, a plurality of openings 109 are provided in the opening setting area 108 to reduce the probability of the light rays reflected by the metal in the light-sensing recognition unit 106 exiting through the opening setting area 108, and to ensure the overall display effect of the display panel 100.

[0044] Optionally, Figure 7 Another cross-sectional structure diagram of the light-sensing recognition area provided by the embodiment of the present invention is shown in Figure 7 As shown, along the thickness direction X of the display panel 100, the central axis L1 of the opening setting area 108 coincides with the central axis L2 of the light-sensing recognition unit 106.

[0045] Among them, to further ensure the recognition effect of the light-sensing recognition unit 106 on the external light, it can be made that along the thickness direction X of the display panel 100, the central axis L1 of the opening setting area 108 coincides with the central axis L2 of the light-sensing recognition unit 106. After the external ambient light enters the display panel 100, the brightest fringe generated by the interference of the light rays can fall on the central area of the light-sensing recognition unit 106, and at the same time, the interference light rays can be evenly distributed in the area of the light-sensing recognition unit 106 other than the central area, so that the light rays can be evenly distributed on the light-sensing recognition unit 106, improving the recognition accuracy of the light-sensing recognition unit 106, and then ensuring the brightness adjustment effect of the display panel 100.

[0046] Optionally, Figure 8 Another cross-sectional structure diagram of the light-sensing recognition area provided by the embodiment of the present invention is Figure 9 Another cross-sectional structure diagram of the light-sensing recognition area provided by the embodiment of the present invention is shown in Figure 8 and Figure 9 As shown, along the thickness direction X of the display panel 100, the first light-shielding layer 107 overlaps at least partially with the light-sensing recognition unit 106.

[0047] Among them, since the external environmental light incident through the opening setting area 108 has a certain irradiation range, it is necessary to ensure that the external environmental light can irradiate on the light sensing recognition unit 106, so as to ensure the light recognition effect of the light sensing recognition unit 106. Therefore, on the premise that the irradiation range of the external environmental light can fall on the light sensing recognition unit 106, at least part of the light sensing recognition unit 106 can be blocked by the first light shielding layer 107. Along the thickness direction X of the display panel 100, as Figure 9 shown, the light sensing recognition unit 106 can overlap with the first light shielding layer 107 in the opening setting area 108; or, as Figure 8 shown, the light sensing recognition unit 106 overlaps with the first light shielding layer 107 surrounding the opening setting area 108. By reasonably setting the position of the light sensing recognition unit 106, it is ensured that part of the external environmental light irradiates on the light sensing recognition unit 106 after passing through the opening 109 of the opening setting area 108, so as to realize the recognition effect of the light sensing recognition unit 106.

[0048] Optionally, continue to refer to Figure 9 , the first light shielding layer 107 includes a first light shielding layer branch 110 located between adjacent openings 109; along the thickness direction X of the display panel 100, the light sensing recognition unit 106 overlaps with at least part of the first light shielding layer branch 110.

[0049] Among them, exemplarily, two openings 109 are provided in the opening setting area 108, and there is a first light shielding layer branch 110 between adjacent openings 109, which can control that along the thickness direction X of the display panel 100, the light sensing recognition unit 106 overlaps with at least part of the first light shielding layer branch 110. As Figure 9 shown, the central axis of the first light shielding layer branch 110 can overlap with the light sensing recognition unit 106, and at the same time, the projection of the light sensing recognition unit 106 completely falls within the projection of the first light shielding layer branch 110, so that the brightest stripe and the surrounding bright and dark alternating stripes of the external environmental light after interference through the opening setting area 108 can fall on the light sensing recognition unit 106, thereby ensuring the recognition effect of the light sensing recognition unit 106..

[0050] Optionally, continue to refer to Figure 8 , the first light shielding layer 107 further includes a second light shielding layer branch 111 provided around the opening setting area 108; along the thickness direction X of the display panel 100, the light sensing recognition unit 106 overlaps with the second light shielding layer branch 111.

[0051] Among them, the light sensing recognition unit 106 is arranged around the opening setting area 108. Exemplarily, as Figure XAs shown, along the thickness direction X of the display panel 100, the projection of the light-sensing recognition unit 106 falls within the projection range of the second light-shielding layer section 111. The distance between the light-sensing recognition unit 106 and the opening setting area 108, the number of openings 109 in the opening setting area 108, and the distance between adjacent openings 109 are reasonably set so that the light-sensing recognition unit 106 is within the illumination range of the external environmental light incident through the opening setting area 108, thereby ensuring the recognition effect of the light-sensing recognition unit 106 and realizing the brightness adjustment of the display panel 100. At the same time, the light-sensing recognition unit 108 overlaps with the second light-shielding layer section 111, and the light reflected by the external environmental light through the light-sensing recognition unit 108 can be blocked by the second light-shielding layer section 111, further effectively reducing the emission of the reflected light and ensuring the display effect of the display panel.

[0052] Optionally, Figure 10 Another structural schematic diagram of the light-sensing recognition area provided by the embodiment of the present invention, Figure 11 is Figure 10 a schematic cross-sectional structure along the section line BB', Figure 12 Another structural schematic diagram of the light-sensing recognition area provided by the embodiment of the present invention, Figure 13 is Figure 12 a schematic cross-sectional structure along the section line CC', as Figure 10 , Figure 11 , Figure 12 and Figure 13 shown, the first light-shielding layer 107 further includes a second light-shielding layer section 111 disposed around the opening setting area 108; the display panel 100 includes a plurality of openings 109 arranged at intervals, and along the direction from the center of the opening setting area 108 to the edge of the opening setting area 108, the width of the opening 109 gradually decreases.

[0053] Among them, a plurality of openings 109 can be provided in the opening setting area 108 of the first light-shielding layer 107. While ensuring that the external environmental light can enter the optical recognition unit through the openings 109 and ensuring the recognition effect of the light-sensing recognition unit 106, a plurality of openings 109 are formed in the opening setting area 108. Corresponding to the opening setting area 108, a plurality of first light-shielding layer sections 110 are also provided. The presence of the first light-shielding layer sections 110 can effectively block the light reflected by the light-sensing recognition unit 106 from exiting, thereby reducing the probability of light emission and ensuring the display effect of the display panel 100. For the case where a plurality of openings 109 are provided in the opening setting area 108, as Figure 10 and 11 shown, the distance between adjacent openings 109 can be the same, or as Figure 12 and Figure 13As shown, the spacing between adjacent openings 109 can be set differently. Exemplarily, along the direction from the center of the opening setting area 108 to the edge of the opening setting area 108, the width of the opening 109 gradually decreases. The central axis of the light sensing recognition unit 106 coincides with the central axis of the opening setting area 108, so that the central area of the light sensing recognition unit 106 can receive the external environmental light incident through the central area of the opening setting area 108, ensuring the recognition accuracy of the light sensing recognition unit 106. At the same time, since the size of the opening 109 in the edge area of the opening setting area 108 is small, the light reflected by the light sensing recognition unit 106 can be blocked by the first light shielding layer section 110, reducing the probability of the reflected light exiting.

[0054] Optionally, Figure 14 is a schematic cross-sectional structure diagram of another light sensing recognition area provided by an embodiment of the present invention. As Figure 7 and Figure 14 shown, the display panel further includes a second light shielding layer 112 on the side of the second substrate 104 away from the first substrate 103; along the thickness direction X of the display panel 100, the second light shielding layer 112 and the first light shielding layer 107 have at least partial overlap, and the second light shielding layer 112 does not overlap with the opening 109.

[0055] Among them, a second light shielding layer 112 is further provided in the second substrate 104. The second light shielding layer 112 is located on the side of the second substrate 104 away from the first substrate 103. The second light shielding layer 112 can be an ink layer. The second light shielding layer 112 can play a certain role in shielding the light reflected by the light sensing recognition unit 106. At the same time, along the thickness direction X of the display panel 100, the second light shielding unit does not overlap with the opening 109 in the opening setting area 108, ensuring that the external environmental light can be incident on the light sensing recognition unit 106. At the same time, along the thickness direction X of the display panel 100, the projection of the second light shielding unit falls within the projection range of the second light shielding layer 112 surrounding the opening setting area 108, ensuring the incident area of the external environmental light, and at the same time further reducing the probability of the light reflected by the light sensing recognition unit 106 exiting, ensuring the display effect of the display panel 100 and improving the user experience.

[0056] Optionally, continuing to refer to Figure 14 , the first light shielding layer further includes a second light shielding layer section 111 provided around the opening setting area 108. Along the thickness direction X of the display panel 100, the edge of the second light shielding layer 112 close to the opening setting area 108 coincides with the edge of the second light shielding layer section 111 close to the opening setting area 108.

[0057] Among them, to further reduce the probability of the light reflected by the light sensing recognition unit 106 from exiting, in the thickness direction X of the display panel 100, the edge of the second light shielding layer 112 close to the opening setting area 108 coincides with the edge of the second light shielding layer branch 111 arranged around the opening setting area 108, ensuring the light flux of the external ambient light incident on the light sensing recognition area 105 to ensure the recognition effect of the light sensing recognition unit 106. At the same time, by controlling the distance between the edge of the second light shielding layer 112 and the opening setting area 108 and increasing the coverage area of the second light shielding layer 112, the probability of the light reflected by the light sensing recognition unit 106 from exiting can be further reduced, enabling part of it to be blocked by the second light shielding layer 112 and ensuring the display effect of the display panel 100.

[0058] Optionally, continue to refer to Figure 7 , the width S of the light sensing recognition unit 106 satisfies:

[0059]

[0060] Among them, D is the minimum distance between the first light shielding layer 107 and the light sensing recognition unit 106 in the thickness direction X of the display panel 100; B is the distance between adjacent openings 109, and λ is the wavelength of visible light.

[0061] Among them, according to the minimum distance between the first light shielding layer 107 and the light sensing recognition unit 106 and the spacing between adjacent openings 109, by reasonably setting the width of the light sensing recognition unit 106, on the premise that light with the same frequency and the same phase interferes, more external ambient light can fall on the light sensing recognition unit 106, ensuring the recognition effect of the light sensing recognition unit 106, and further realizing the brightness adjustment of the display panel 100.

[0062] Optionally, continue to refer to Figure 7 , the width of the opening 109 is M, where 10 μm ≤ M ≤ 15 μm.

[0063] Among them, by reasonably setting the width of the opening 109 in the opening setting area 108, ensuring that the external ambient light can be incident on the light sensing recognition unit 106 in the light sensing recognition area 105, the light sensing recognition unit 106 can achieve the light recognition effect. At the same time, by reasonably setting the width of the opening 109 in the opening setting area 108, the probability of the light reflected by the light sensing recognition unit 106 or the metal trace on one side of the first substrate 103 from exiting through the opening setting area 108 can be effectively reduced, ensuring the user experience.

[0064] Optionally, Figure 15 is a schematic cross-sectional structure diagram of another light sensing recognition area provided by an embodiment of the present invention. Figure 16 is a schematic cross-sectional structure diagram of another light sensing recognition area provided by an embodiment of the present invention, as Figure 7, Figure 15 and Figure 16 As shown in Figure 15 and Figure 16 , in any plane parallel to the vertical light-emitting direction of the display panel 100, the shape of the opening 109 is at least one of a rectangle, a regular trapezoid, or an inverted trapezoid.

[0065] Exemplarily, it can be, for example, Figure 7 the rectangle shown in Figure 7 , or Figure 15 the regular trapezoid shown in Figure 15 , or Figure 16 the inverted trapezoid shown in Figure 16 . The above-mentioned setting methods can all effectively reduce the probability of the light reflected by the light-sensing recognition unit 106 exiting through the opening setting area 108. The shape of the opening 109 can be designed according to actual design requirements, and the embodiments of the present invention do not make specific limitations.

[0066] Optionally, continuing to refer to Figure 2 , the display area 101 is provided with a liquid crystal layer located between the first substrate 103 and the second substrate 104. The non-display area 102 includes a sealant area 1021 surrounding the liquid crystal layer, and the light-sensing recognition area 105 is located within the sealant 1021 area. Figure 2

[0067] Among them, in the display area 101, a liquid crystal layer is provided in the first substrate 103 and the second substrate 104 to ensure the normal display effect of the display area 101. In the non-display area 102, since it is not used for display, no liquid crystal layer is provided between the first substrate 103 and the second substrate 104. To prevent the liquid crystal molecules in the liquid crystal layer from leaking out, a sealant area is usually provided in the non-display area 102 and blocked by sealant. The sealant area has a certain width. By setting the light-sensing recognition area 105 in the sealant area 1021, since there are no liquid crystal molecules in the sealant area 1021, external ambient light can directly enter the light-sensing recognition unit 106, reducing light loss, ensuring the recognition effect of the light-sensing recognition unit 106, and further ensuring the brightness adjustment effect of the display panel 100.

[0068] Figure 17 The structural schematic diagram of a display device provided by an embodiment of the present invention is as shown in Figure 17 . Figure 17 The display device 200 includes the display panel 100 described in the above embodiment.

[0069] It should be noted that since the display device provided in this embodiment has the same or corresponding beneficial effects as the display panel of the above embodiment, it will not be elaborated here. The display device 200 provided by the embodiment of the present invention can be Figure 17 the mobile phone shown in Figure 17 , or any electronic product with a display function, including but not limited to the following categories: televisions, laptop computers, desktop monitors, tablet computers, digital cameras, smart bracelets, smart glasses, in-vehicle displays, medical devices, industrial control devices, touch interaction terminals, etc. The embodiments of the present invention do not make special limitations on this.

[0070] The above specific embodiments do not constitute a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications, combinations, sub - combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
