[0034] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0035] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0036] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "an", "the" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0037] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0038] In the description of this specification, it is necessary to understand that the words such as "substantially", "approximately", "approximately", "about", "roughly", "substantially" and the like described in the claims and embodiments of the present application refer to what can be generally recognized within a reasonable process operation range or tolerance range, rather than an exact value.

[0039] It should be understood that although the terms first, second, etc. may be used to describe touch electrodes, closed openings, etc. in the embodiments of the present application, these should not be limited to these terms. These terms are only used to distinguish touch electrodes, closed openings, etc. from each other. For example, without departing from the scope of the embodiments of the present application, the first touch electrode may also be referred to as the second touch electrode, and similarly, the second touch electrode may also be referred to as the first touch electrode. The applicant of this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0040] Figure 1 A schematic diagram of a display panel provided in an embodiment of the present application.

[0041] like Figure 1 As shown, the display panel 001 includes a display area AA, and the display area AA is the main area in the display panel 001 for light-emitting display. Among them, the display panel 001 includes a plurality of sub-pixels 20, and the sub-pixels 20 are located in the display area AA and the sub-pixels 20 can be the area in the display panel 001 for light-emitting display. The display panel 001 can be an active light-emitting display panel 001, and the sub-pixels 20 can include a plurality of light-emitting devices, for example, the sub-pixels 20 in the display panel 001 include organic light-emitting diodes (OLEDs). The display panel 001 can be a passive light-emitting display panel 001, for example, the display panel 001 is a liquid crystal display panel 001 (LCD), an electrophoretic display panel 001 (EPD), and the sub-pixels 20 can be a controllable light-emitting area defined by a pixel electrode, etc. For clear explanation, the embodiment of the present application is described by taking the display panel 001 as an organic light-emitting display panel 001 as an example.

[0042] In addition, the display panel 001 may further include a non-display area NA, which is located at the periphery of the display area AA and is a main area in the display panel 001 for setting peripheral wiring, peripheral circuits, etc.

[0043] Figure 2 for Figure 1A schematic cross-sectional view along the A1-A2 direction.

[0044] Combination Figure 1 and Figure 2 , the display panel 001 includes a substrate 01, a light emitting device layer 02, and a touch layer 03, wherein the light emitting device layer 02 and the touch layer 03 are located on the same side of the substrate 01. The light emitting device layer 02 includes a plurality of sub-pixels 20 and the sub-pixels 20 are located in the display area AA. Figure 2 As shown, the light-emitting device layer in the display panel 001 includes light-emitting devices, and the light-emitting devices may be organic light-emitting diodes at least partially disposed in openings of the pixel definition layer 04 , and the openings of the pixel definition layer 04 may define the area where the sub-pixel 20 is located.

[0045] like Figure 1 As shown, the touch layer 03 includes a plurality of touch electrodes 30, the touch electrodes 30 include touch lines 31 and the touch lines 31 intersect to form a plurality of openings 300; that is, the touch electrodes 30 are a grid structure, and the touch lines 31 intersect to form a mesh structure defining a plurality of openings 300. Please continue to refer to Figure 1 and Figure 2 , the plurality of openings 300 include a first closed opening 301 and a second closed opening 302. In a direction perpendicular to the plane where the substrate 01 is located, the first closed opening 301 at least partially overlaps with the sub-pixel 20, and the second closed opening 302 does not overlap with the sub-pixel 20. That is, some of the openings 300 in the plurality of openings 300 are first closed openings 301 and some of the openings 300 are second closed openings 302. Moreover, the first closed opening 301 is a closed opening that at least partially overlaps with the sub-pixel 20 in a direction perpendicular to the plane where the substrate 01 is located; the second closed opening 302 is a closed opening that does not overlap with the sub-pixel 20 in a direction perpendicular to the plane where the substrate 01 is located.

[0046] It should be noted that the touch wires 31 outside the closed opening 300 surround the opening 300 , that is, the touch wires 31 outside the first closed opening 301 form a closed structure and the touch wires 31 outside the second closed opening 302 form a closed structure.

[0047] In the embodiment of the present application, the first closed opening 301 overlaps with the sub-pixel 20 in a direction perpendicular to the plane where the substrate 01 is located. Then, in the direction perpendicular to the plane where the substrate 01 is located, the first closed opening 301 exposes at least a portion of the sub-pixel 20, for example, Figure 1 and Figure 2 As shown, the first closed opening 301 completely exposes the sub-pixel 20 .

[0048] In order to avoid the influence of the touch electrode 30 on the light emitted by the sub-pixel 20, the touch electrode 30 is a grid structure including touch lines 31 and the touch lines 31 cross to form a first closed opening 301. The electrical stability of the touch electrode 30 formed by the touch lines 31 extending and crossing in different directions depends on the reliability of the cross-connection of the touch lines 31. In the embodiment of the present application, the touch lines 31 in the touch electrode 30 not only cross to form the first closed opening 301 overlapping with the sub-pixel 20, but also form a second closed opening 302 that does not overlap with the sub-pixel 20. The touch lines 31 outside the second closed opening 302 cross to form a closed structure, which increases the cross-connection position of the touch lines 31 in the touch electrode 30, thereby reducing the impedance of the touch electrode 30 and the reliability of the cross-connection of the touch lines 31 in the touch electrode 30.

[0049] like Figure 1 As shown, the plurality of sub-pixels 20 include a first color sub-pixel 21, a second color sub-pixel 22, and a third color sub-pixel 23, and the first color, the second color, and the third color are different colors. One of the first color sub-pixel 21, the second color sub-pixel 22, and the third color sub-pixel 23 can be a red sub-pixel 20, one can be a green sub-pixel 20, and one can be a blue sub-pixel 20.

[0050] Figure 3 A partial schematic diagram of a display panel provided in an embodiment of the present application.

[0051] In some embodiments of the present application, Figure 3 As shown, the display panel 001 includes a first pixel group 20a and a second pixel group 20b arranged alternately along the second direction Y, the first pixel group 20a includes first color sub-pixels 21 and second color sub-pixels 22 arranged alternately along the first direction X, and the second pixel group 20b includes third color sub-pixels 23 arranged in sequence along the first direction X. For example, Figure 3 As shown, the first pixel group 20a and the second pixel group 20b are arranged alternately along the column direction. The first pixel group 20a includes the first color sub-pixels 21 and the second color sub-pixels 22 arranged alternately along the row direction, and does not include the third color sub-pixels 23. The second pixel group 20b includes the third color sub-pixels 23 arranged in sequence along the row direction, and does not include the first color sub-pixels 21 and the second color sub-pixels 22.

[0052] In addition, the plurality of first color sub-pixels 21 and the plurality of second color sub-pixels 22 are alternately arranged along the second direction Y, and the connection line of the third color sub-pixels 23 arranged along the second direction Y is located between the first color sub-pixels 21 and the second color sub-pixels 22 adjacently arranged along the first direction X. For example, Figure 3As shown, the first color sub-pixel 21 and the second color sub-pixel 22 are also arranged alternately along the column direction, and the center of the third color sub-pixel 23 is offset from the center of the first color sub-pixel 21 in the column direction, and the center of the third color sub-pixel 23 is offset from the center of the second color sub-pixel 22 in the column direction.

[0053] In these embodiments, the third color sub-pixel 23 is misaligned with the first color sub-pixel 21 and the second color sub-pixel 22 in the second direction Y, so the distance between the first pixel group 20a and the second pixel group 20b in the second direction Y can be smaller; accordingly, the third color sub-pixel 23 is misaligned with the first color sub-pixel 21 and the second color sub-pixel 22 in the first direction X, so the distance between the pixel group composed of the first color sub-pixel 21 and the second color sub-pixel 22 arranged alternately along the second direction Y and the pixel group composed of the third color pixel 23 arranged sequentially along the second direction Y in the first direction X can be smaller, but the distance between the third color sub-pixel 23, the first color sub-pixel 21, and the second color sub-pixel 22 is not too small. In this way, the design difficulty of the sub-pixel 20 is low and rendering is easy to achieve.

[0054] In some technical solutions, such as Figure 3 As shown, the area of ​​at least one of the first color sub-pixel 21 and the second color sub-pixel 22 is larger than the area of ​​the third color sub-pixel 23. Figure 3 As shown, the area of ​​the first color sub-pixel 21 is significantly larger than the area of ​​the third color sub-pixel 23 .

[0055] The third color sub-pixel 23 may be a green sub-pixel, one of the first color sub-pixel 21 and the second color sub-pixel 22 may be a red sub-pixel and the other may be a blue sub-pixel.

[0056] Further, the area of ​​the first color sub-pixel 21 may be smaller than the area of ​​the second color sub-pixel, and the first color sub-pixel 21 may be a red sub-pixel, and the second color sub-pixel may be a blue sub-pixel.

[0057] In these embodiments, since the first color sub-pixel 21, the second color sub-pixel 22, and the third color sub-pixel 23 are not arranged in a matrix along the first direction X and the second direction Y, and Figure 3As shown, the distance between the third color pixel column composed of the plurality of third color sub-pixels 23 arranged along the second direction Y and the first color pixel column composed of the plurality of first color sub-pixels 21 arranged along the second direction Y is smaller in the first direction X, the distance between the third color pixel column composed of the plurality of third color sub-pixels 23 arranged along the second direction Y and the second color pixel column composed of the plurality of second color sub-pixels 22 arranged along the second direction Y is smaller in the first direction X, and the distance between the adjacent first pixel group 20a and the second pixel group 20b is smaller in the second direction Y. Since the touch line 31 should not overlap with the sub-pixel 20 in a direction perpendicular to the plane where the substrate 01 is located, it is more difficult to design the touch line 31 as a mesh structure extending along the first direction X and the second direction Y. Therefore, as shown in FIG. Figure 3 As shown, the touch line 31 is designed to be wound accordingly to form a first closed opening 301 and a second closed opening 302. The winding design means that the extension direction of the touch line 31 corresponding to the periphery of the sub-pixel 20 includes multiple directions and at least some of the directions intersect with the first direction X and the second direction Y.

[0058] Alternatively, if Figure 3 As shown, the touch control lines 31 are basically straight lines.

[0059] Figure 4 A partial schematic diagram of a display panel provided in an embodiment of the present application.

[0060] Alternatively, if Figure 4 As shown in FIG. 1 , at least part of the touch line 31 is a curve. Figure 4 As shown, the peripheral touch line 31 of the first closed opening 301 overlapping with the third color sub-pixel 23 in a direction perpendicular to the plane where the substrate is located can be a circular winding line.

[0061] In one implementation of these embodiments, Figure 3 As shown, the shapes of the first color sub-pixel 21 , the second color sub-pixel 22 and the third color sub-pixel 23 are all circular.

[0062] Figure 5 A partial schematic diagram of a display panel provided in an embodiment of the present application.

[0063] In one implementation of these embodiments, Figure 5 As shown, the shapes of the first color sub-pixel 21, the second color sub-pixel 22 and the third color sub-pixel 23 are all polygonal. Figure 5 As shown, the first color sub-pixel 21 and the second color sub-pixel 22 are both quadrilateral in shape, and the third color sub-pixel 23 is an octagon in shape.

[0064] In addition, when the shape of the sub-pixel 20 is a polygon, the shape of the first closed opening 301 overlapping the sub-pixel 20 may also be a corresponding polygon. Figure 5 As shown, the shapes of the first color sub-pixel 21 and the second color sub-pixel 22 are both quadrilaterals, so the shapes of the first closed opening 301 overlapping the first color sub-pixel 21 and the first closed opening 301 overlapping the second color sub-pixel 22 can also be quadrilaterals; the shape of the third color sub-pixel 23 is an octagon, so the shape of the first closed opening 301 overlapping the third color sub-pixel 23 can also be an octagon. At this time, the touch line 31 outside the first closed opening 301 can be parallel to the edge of the first closed opening 301, so that the distance between the sub-pixel 20 and the touch line 31 outside it remains basically unchanged, reducing the risk of the touch line 31 overlapping the sub-pixel 20.

[0065] Correspondingly, the shape of the second closed opening 302 can adapt to the shape of the first closed opening 301. In one technical solution, the number of edges included in the shape of the third color sub-pixel 23 is equal to the number of edges included in the shape of the first closed opening 301 where the third color sub-pixel 23 is located. Figure 5 If the shape of the third color sub-pixel 23 is an octagon, the shape of the second closed opening 302 may be a triangle, so that the shape of the first closed opening 301 overlapping with the third color sub-pixel 23 in a direction perpendicular to the plane where the substrate 01 is located is an octagon.

[0066] In some embodiments of the present application, in at least one direction, the sub-pixels 20 adjacent to the second closed opening 302 and located on both sides of the second closed opening 302 have the same color. Figure 1 As shown, in the second direction Y, the sub-pixels 20 adjacent to the second closed opening 302 and located on both sides of the second closed opening 302 are all second color sub-pixels 22. Figure 3 As shown, in the first direction X, the sub-pixels 20 adjacent to the second closed opening 302 and located on both sides of the second closed opening 302 are all third color sub-pixels 23. Figure 4 As shown, in the second direction Y, the sub-pixels 20 adjacent to the second closed opening 302 and located on both sides of the second closed opening 302 are all third color sub-pixels 23. Figure 5 As shown, in the first direction X, the sub-pixels 20 adjacent to the second closed opening 302 and respectively located on both sides of the second closed opening 302 are all third color sub-pixels 23; in the second direction Y, the sub-pixels 20 adjacent to the second closed opening 302 and respectively located on both sides of the second closed opening 302 are all third color sub-pixels 23.

[0067] In these embodiments, the distance between the sub-pixels 20 of the same color arranged adjacently in one direction is generally larger, so the corresponding area between the adjacently arranged sub-pixels 20 has a larger space for setting the second closed opening 302, and the distance between the second closed opening 302 and the sub-pixel 20 in a plane parallel to the substrate has the opportunity to be set larger, effectively reducing the risk of the touch line outside the second closed opening 302 affecting the emitted light of the sub-pixel 20.

[0068] In some embodiments of the present application, Figure 3 and Figure 5 As shown, at least part of the first closed opening 301 has a first shape and the first shape includes m sides, and the second closed opening 302 has a second shape and the second shape includes n sides, where n<m. Figure 3 As shown, the shape of the first closed opening 301 is a hexagon including 6 sides, and the shape of the second closed opening 302 is a quadrilateral including 4 sides; for example, Figure 5 As shown, the shape of the first closed opening 301 is an octagon including 8 sides, and the shape of the second closed opening 302 is a triangle including 3 sides.

[0069] The number of touch lines outside the second closed opening 302 is smaller than that outside the first closed opening 301 . On the one hand, the design difficulty of the second closed opening 302 is smaller; on the other hand, the space occupied by the touch lines outside the second closed opening 302 can also be smaller, reducing its influence on the design of the sub-pixel 20 .

[0070] In some embodiments of the present application, Figure 1 and Figure 3-Figure 5 As shown, the opening area of ​​the second closed opening 302 is smaller than the opening area of ​​the first closed opening 301 .

[0071] The second closed opening 30 occupies a smaller area than the first closed opening 301 , so the introduction of the second closed opening 30 will not affect the design of the sub-pixel 20 too much.

[0072] In the embodiment of the present application, the touch electrode 30 may be a self-capacitive touch electrode 30 or a mutual-capacitive touch electrode 30. The present application does not limit this. The following description is made by taking the touch electrode 30 as a mutual-capacitive touch electrode 30 as an example.

[0073] Figure 6 A schematic diagram of a local touch electrode of a display panel provided in an embodiment of the present application.

[0074] like Figure 6As shown, the touch electrode 30 includes a first touch electrode 30a and a second touch electrode 30b, that is, some of the touch electrodes 30 in the display panel 001 are first touch electrodes 30a and some of the touch electrodes 30 are second touch electrodes 30b, wherein one of the first touch electrode 30a and the second touch electrode 30b can be a touch driving electrode and the other can be a touch sensing electrode.

[0075] Please continue to refer to Figure 6 , the display panel 001 includes a plurality of first touch electrode groups 3a extending along a first direction X and arranged along a second direction Y, and a plurality of second touch electrode groups 3b extending along the second direction Y and arranged along the first direction X. Among them, the first touch electrode group 3a includes a plurality of first touch electrodes 30a arranged and electrically connected along the first direction X, and the second touch electrode group 3b includes a plurality of second touch electrodes 30b arranged and electrically connected along the second direction Y. The first direction X and the second direction Y intersect, for example, the first direction X is perpendicular to the second direction Y. Then the extension direction of the first touch electrode group 3a intersects with the extension direction of the second touch electrode group 3b. It should be noted that, Figure 6 Only the touch electrodes 30 in a partial area of ​​the display panel 001 are illustrated. Therefore, the first touch electrode group 3a in the display panel 001 may include more first touch electrodes 30a arranged along the first direction X and the second touch electrode group 3b may include more second touch electrodes 30b arranged along the second direction Y.

[0076] Figure 7 for Figure 6 Schematic diagram of the local details of the touch electrode corresponding to the R1 area.

[0077] Combination Figure 6 and Figure 7 , the first touch electrode group 3a may also include a first connection pattern 300a, and two adjacent first touch electrodes 30a in the first touch electrode group 3a are electrically connected through the first connection pattern 300a; the second touch electrode group 3b also includes a second connection pattern 300b, and two adjacent second touch electrodes 30b in the second touch electrode group 3b are electrically connected through the second connection pattern 300b. Then, the first touch electrode group 3a is an integral structure consisting of at least the first touch electrode 30a and the first connection pattern 300a, and the second touch electrode group 3b is an integral structure consisting of at least the second touch electrode 30b and the second connection pattern 300b. Among them, the first connection pattern 300a may be a portion of the first touch electrode group 3a that overlaps with the second touch electrode group 3b in a direction perpendicular to the plane where the substrate 01 is located, and the second connection pattern 300b may also be a portion of the second touch electrode group 3b that overlaps with the first touch electrode group 3a in a direction perpendicular to the plane where the substrate 01 is located.

[0078] It should be noted that Figure 7 The second touch electrode 30b includes a second closed opening 302. Figure 7 This is only an illustration of a situation where the touch electrode 30 includes the second closed opening 302. However, the second closed opening 302 can be arranged in other ways. Figure 7 For example, in some cases, the first touch electrode 30a may include a second closed opening 302, the first connection pattern 300a may include a second closed opening 302, and the second connection pattern 300b may also include a second closed opening 302.

[0079] Figure 8 for Figure 7 Schematic diagram of the cross section along the B1-B2 direction.

[0080] In order to avoid short circuit between the first touch electrode group 3a and the second touch electrode group 3b, Figure 7 and Figure 8 , the first connection pattern 300a and the second connection pattern 300b are located in different conductive film layers. For example, the second connection pattern 300b and the first touch electrode 30a and the second touch electrode 30b are located in the same conductive film layer, and the first connection pattern 300a and the second connection pattern 300b are located in different conductive film layers, then the first connection pattern 300a is equivalent to the connection pattern formed by the jumper at the position where the first touch electrode group 3a intersects with the second touch electrode group 3b.

[0082] In this application, if Fig. 9 As shown, the display area AA may further include at least one optical detection area LA, and the optical detection area LA may allow detection light to pass through so that the optical sensor LS receives the detection light. The optical detection area LA may include the optical sensor LS. Fig.10 As shown, the optical sensor LS can be built into the display panel 001. For example, the optical sensor LS can be prepared simultaneously with the light-emitting device in the sub-pixel 20. The optical detection area LA can also be used to overlap with the optical sensor LS. In this case, Fig.11 As shown, the optical sensor LS is a device external to the display panel 001 and the optical detection area LA is an area reserved in the display panel 001 for overlapping with the optical sensor LS.

[0083] The optical sensor LS may be used to collect images of objects to be photographed when taking photos, and may also be used to collect fingerprint images, facial images, etc. when performing biometric identification.

[0084] Combination Fig. 9 and Fig.10 , Fig.11 , along the direction perpendicular to the plane where the substrate 01 is located, the optical detection area LA may overlap with the second closed opening 302, and at least part of the second closed opening 302 exposes the optical detection area LA in the direction perpendicular to the plane where the substrate 01 is located. Therefore, the detection light passing through the optical detection area LA will pass through the second closed opening 302 and will not be substantially blocked by the touch line 31 in the touch electrode 30.

[0085] Among them, the touch line 31 outside the second closed opening 302 overlapping with the optical detection area LA in the direction perpendicular to the plane where the substrate 01 is located can reduce the probability that the light emitted by the surrounding sub-pixels 20 enters the optical detection area LA, thereby increasing the accuracy of the detection light received by the optical sensor LS. In addition, if the optical sensor LS displays the detection light outside the panel 001, the touch line 31 outside the second closed opening 302 overlapping with the optical detection area LA in the direction perpendicular to the plane where the substrate 01 is located can reduce the probability that the light from the optical detection area LA is emitted to the area where the surrounding sub-pixels 20 are located, thereby increasing the effective amount of the detection light.

[0086] Fig.12 for Fig. 9 Another cross-sectional schematic diagram along the C1-C2 direction.

[0087] In some embodiments of the present application, Fig.12 As shown, the display panel 001 may further include a black matrix layer 05, and the black matrix layer 05 is located on the side of the film layer where the touch electrode 30 is located away from the substrate 01, that is, the black matrix layer 05 is located on the side of the touch layer 03 away from the substrate 01. The black matrix layer 05 includes a light shielding structure 51 and a plurality of first hollow portions 501 and at least one second hollow portion 502 defined by the light shielding structure 51. In the direction perpendicular to the plane where the substrate 01 is located, the first hollow portion 501 overlaps with the sub-pixel 20, and the second hollow portion 502 overlaps with the optical detection area LA, that is, part of the hollow portions 50 in the black matrix layer 05 is the first hollow portion 501 overlapping with the sub-pixel 20 in the direction perpendicular to the plane where the substrate 01 is located, and part of the hollow portion 50 is the second hollow portion 502 overlapping with the sub-pixel 20 in the direction perpendicular to the plane where the substrate 01 is located.

[0088] Among them, the first hollow portion 501 of the black matrix layer 05 exposes at least part of the sub-pixel 20 in a direction perpendicular to the plane where the substrate 01 is located, and the light shielding structure 51 of the black matrix layer 05 is included between at least part of the adjacent sub-pixels 20, so the black matrix layer 05 does not affect the emission of light emitted by the sub-pixel 20, and can reduce the light crosstalk between adjacent sub-pixels 20. In addition, the first hollow portion 501 can be filled with a color resist 500, and the color resist 500 is the same color as the sub-pixel 20 overlapping therewith, so as to filter the light emitted by the sub-pixel to obtain light with purer chromaticity and reduce the reflection of ambient light.

[0089] The second hollow portion 502 of the black matrix layer 05 overlaps with the optical detection area LA in a direction perpendicular to the plane of the substrate 01 , which can reduce the influence of the light emitted by the sub-pixel 20 on the detection light passing through the optical detection area.

[0090] When the display panel 001 includes a black matrix layer 05 and the black matrix layer 05 includes a first hollow portion 501 and a second hollow portion 502, since the optical detection area LA overlaps with the second closed opening 302 in a direction perpendicular to the plane of the substrate 01, and overlaps with the second hollow portion 502 in a direction perpendicular to the plane of the substrate 01, the second hollow portion 502 and the second closed opening 302 in a direction perpendicular to the plane of the substrate 01 can have a better collimation effect on the detection light.

[0091] Fig.13 A schematic diagram of the distribution of an optical detection area and a second closed opening in a display panel provided in an embodiment of the present application.

[0092] In some embodiments, Fig.13 As shown, the optical detection area LA can be distributed relatively evenly in the display area AA, so the display area AA of the display panel 001 can realize full-screen optical detection. For example, fingerprint recognition can be performed at any position of the display area AA of the display panel 001. Correspondingly, since the optical detection area LA overlaps with the second closed opening 302 in a direction perpendicular to the plane where the substrate 01 is located, the second closed opening 302 can also be distributed relatively evenly in the display area AA.

[0093] In one implementation, when the optical detection area LA is uniformly distributed in the display area AA, each second closed opening 302 may overlap with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located. In this implementation, any second closed opening 302 is an opening 300 that overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located.

[0094] In addition, in one implementation, when the display panel 001 includes a black matrix layer 05 and the black matrix layer 05 includes a first hollow portion 501 and a second hollow portion 502, each second hollow portion 502 may overlap with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located. In this implementation, any second hollow portion 502 is a hollow portion 50 that overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located.

[0095] It should be noted that, in order to clearly illustrate the distribution of the second closed openings 302, Fig.13 Only the portion of the touch lines 31 included in the touch electrodes 30 that is located outside the second closed opening 302 and defines the second closed opening 302 is illustrated. However, the touch electrodes 30 in the display panel 001 provided in the embodiment of the present application are of a grid structure.

[0096] Fig.14 A schematic diagram of the distribution of optical detection areas in a display panel provided in an embodiment of the present application.

[0097] In some embodiments, Fig.14 As shown, the display area AA includes a first display area AA1 and a second display area AA2. Both the first display area AA1 and the second display area AA2 include a plurality of sub-pixels 20 and the optical detection area LA is located in the first display area AA1. The first display area AA1 is a position in the display area AA that includes the optical detection area LA. Accordingly, the second display area AA2 may not include the optical detection area LA. In these embodiments, if the display panel 001 includes a plurality of optical detection areas LA, the optical detection areas LA may be more concentrated in the first display area AA1. It should be noted that Fig. 9 The case where the display area AA includes one first display area AA1 is illustrated in FIG. 1 , however, the display area AA may also include a plurality of first display areas AA1 and each first display area AA1 includes the optical detection area LA.

[0098] In addition, in order to enhance the user experience, the first display area AA1 including the optical detection area LA also includes a plurality of sub-pixels 20 for light-emitting display to ensure the integrity of the display area AA when displaying the picture. Among them, the area of ​​the pixel circuit in the first display area AA1 can be smaller than the area of ​​the pixel circuit in the second display area AA2, or the pixel circuit electrically connected to at least part of the sub-pixels 20 in the first display area AA1 can be arranged in the second display area AA2, or the transmittance of the signal line in the first display area AA1 is greater than the transmittance of the signal line in the second display area AA2, so that the second display area AA2 has a higher optical transmittance than the first display area AA1, thereby allowing more detection light to reach the optical sensor LS from the optical detection area LA.

[0099] In these embodiments, since the optical detection area LA overlaps with the second closed opening 302 along a direction perpendicular to the plane where the substrate 01 is located, at least a portion of the second closed opening 302 is located in the first display area AA1.

[0100] Fig.15 A schematic diagram of the distribution of an optical detection area and a second closed opening in a display panel provided in an embodiment of the present application, Fig.16 A schematic diagram of partial details of a display panel provided in an embodiment of the present application.

[0101] In an implementation method corresponding to these embodiments, in combination Fig.15 and Fig.16 , the second closed openings 302 are all located in the first display area AA1, that is, the second closed openings 302 are only arranged in the first display area AA1 including the optical detection area LA. That is, the position of the second closed openings 302 corresponds to the position of the optical detection area LA, and the second closed openings 302 are relatively concentrated in the first display area AA1 and there are basically no second closed openings 302 in the second display area AA2, so as to reduce the difficulty of preparing the second closed openings 302.

[0102] Fig.17 A schematic diagram of the distribution of an optical detection area and a second closed opening in a display panel provided in an embodiment of the present application, Fig.18 A schematic diagram of partial details of a display panel provided in an embodiment of the present application.

[0103] In an implementation method corresponding to these embodiments, in combination Fig.17 and Fig.18 , part of the second closed opening 302 is located in the first display area AA1 and part of the second closed opening 302 is located in the second display area AA2, that is, part of the second closed opening 302 overlaps with the optical detection area LA in a direction perpendicular to the plane of the substrate 01 and is located in the first display area AA1, and part of the second closed opening 302 does not overlap with the optical detection area LA in a direction perpendicular to the plane of the substrate 01 and is located in the second display area AA2.

[0104] In a solution corresponding to this implementation, combined with Fig.17 and Fig.18As shown, each first touch electrode group 3a includes a second closed opening 302, and along the second direction Y, the second closed opening 302 included in the first touch electrode group 3a overlaps with the first display area AA1, that is, the second closed opening 302 included in each first touch electrode group 3a overlaps with the first display area AA1 in the arrangement direction of the first touch electrode group 3a. Then, along the extension direction of the first touch electrode group 3a, except for the position aligned with the first display area AA1 in the second direction Y, there may be no second closed opening 302 in other positions of the first touch electrode group 3a. For example, Fig.18 As shown, the first touch electrode 30a in the first display area AA1 includes a second closed opening 302; in addition, an area in the second display area AA2 that is substantially flush with the first display area AA1 in the second direction Y is the second area AA22, and the first touch electrode 30a in the second area AA22 includes a second closed opening 302.

[0105] Since the second closed opening 302 included in the first touch electrode group 3a overlaps with the first display area AA1 in the second direction Y, the first touch electrode 30a located in the first display area AA1 includes the second closed opening 302, that is, at least part of the second closed opening 302 in the first display area AA1 is formed by the intersection of the touch lines 31 in the first touch electrode 30a. When each of the first touch electrode groups 3a includes the second closed opening 302 and the second closed opening 302 included in the first touch electrode group 3a overlaps with the first display area AA1 in the second direction Y, then in the extension direction of the first touch electrode group 3a, substantially the same position of each of the first touch electrode groups 3a includes the second closed opening 302, and the impedance substrates of each of the first touch electrode groups 3a are the same, which can improve the touch accuracy of the display panel 001.

[0106] In addition, combined Fig.17 and Fig.18 , each second touch electrode group 3b may also include a second closed opening 302, and along the first direction X, the second closed opening 302 included in the second touch electrode group 3b overlaps with the first display area AA1, that is, the second closed opening 302 included in each second touch electrode group 3b overlaps with the first display area AA1 in the arrangement direction of the second touch electrode group 3b. Then, along the extension direction of the second touch electrode group 3b, except for the position aligned with the first display area AA1 in the first direction X, there may be no second closed opening 302 in other positions of the second touch electrode group 3b. For example, Fig.18As shown, the second touch electrode 30b in the first display area AA1 includes a second closed opening 302; in addition, an area in the second display area AA2 that is substantially flush with the first display area AA1 in the first direction X is the first area AA21, and the second touch electrode 30b in the first area AA21 includes a second closed opening 302.

[0107] Since the second closed opening 302 included in the second touch electrode group 3b overlaps with the first display area AA1 in the first direction X, the second touch electrode 30b located in the first display area AA1 includes the second closed opening 302, that is, at least part of the second closed opening 302 in the first display area AA1 is formed by the intersection of the touch lines 31 in the second touch electrode 30b. When each second touch electrode group 3b includes the second closed opening 302 and the second closed opening 302 included in the second touch electrode group 3b overlaps with the first display area AA1 in the first direction X, then in the extension direction of the second touch electrode group 3b, substantially the same position of each second touch electrode group 3b includes the second closed opening 302, and the impedance of each second touch electrode group 3b is substantially the same, which can improve the touch accuracy of the display panel 001.

[0108] In addition, when the first touch electrodes 30a and the second touch electrodes 30b in the first display area AA1 both include the second closed openings 302, the number of the second closed openings 302 in the first display area AA1 is relatively large, which is beneficial for setting more optical detection areas LA in the first display area AA1 and for more detection light to pass through the optical detection areas LA. In addition, the impedances of the first touch electrode groups 3a are the same and the impedances of the second touch electrode groups 3b are substantially the same, which can improve the touch accuracy of the display panel 001.

[0109] In one embodiment, each first touch electrode group 3a includes a second closed opening 302, and along the second direction Y, the second closed opening 302 included in the first touch electrode group 3a overlaps with the first display area AA1, and the second touch electrode group 3b does not include the second closed opening 302; or, each second touch electrode group 3b includes a second closed opening 302, and along the second direction Y, the second closed opening 302 included in the second touch electrode group 3b overlaps with the first display area AA1, and the first touch electrode group 3a does not include the second closed opening 302.

[0110] Fig.19 for Fig.18 A schematic cross-sectional view along the D1-D2 direction.

[0111] In a solution corresponding to this implementation, if Fig.19As shown, when the display panel 001 includes a black matrix layer 05 and the black matrix layer 05 includes a light shielding structure 51 and a plurality of first hollow portions 501 and at least one second hollow portion 502 defined by the light shielding structure 51 as described above, in combination with Fig.19 As shown, the plurality of second closed openings 302 may include a first sub-opening 302a and a second sub-opening 302b. Along a direction perpendicular to the plane where the substrate 01 is located, the first hollow portion 501 overlaps with the sub-pixel 20, the first sub-opening 302a overlaps with the optical detection area LA and the first sub-opening 302a overlaps with the second hollow portion 502, the second sub-opening 302b does not overlap with the optical detection area LA and the second sub-opening 302b overlaps with the light shielding structure 51. In the present technical solution, part of the second closed opening 302 is the first sub-opening 302a overlapping with the optical detection area LA and the second hollow portion 502, and part of the second closed opening 302 is the second sub-opening 302b not overlapping with the optical detection area LA and the second hollow portion 502, which means that the second closed opening 302 not overlapping with the optical detection area LA is blocked by the shading structure 51 in the black matrix layer 05, thereby reducing the visibility of the touch line 31 around the second closed opening 302 and improving the visual effect of the display panel 001.

[0112] In addition, when the second closed opening 302 that has no overlap with the optical detection area LA in a direction perpendicular to the plane of the substrate 01 is located in the second display area AA2, the touch line 31 located outside the second closed opening 302 in the second display area AA2 is blocked by the shading structure 51 in the black matrix layer 05, which can effectively reduce the impact of the design of the second closed opening 302 on the visual effect of the display panel 001.

[0113] Fig. 20 A schematic diagram of the distribution of second closed openings and optical detection areas in a display panel provided in an embodiment of the present application.

[0114] In one implementation, when the optical detection area LA is located in the first display area AA1 and the second display area AA2 also includes the second closed opening 302, as shown in FIG. Fig.18As shown, the second closed openings 302 are periodically arranged in the display area AA with the second opening group as a repeating unit, and the second opening group includes a plurality of second closed openings 302. Among them, the first display area AA1 includes the second closed openings 302 overlapping with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located, and the arrangement rule of the second closed openings 302 in the first display area AA1 is adapted to the arrangement rule of the optical detection area LA. When the second closed openings 302 are periodically arranged in the display area AA with the second opening group as a repeating unit, it means that all the second closed openings 302 including the second closed openings 302 in the first display area AA1 are periodically arranged with the second opening group as a repeating unit, and therefore, the second closed openings 302 in the first display area AA1 and the second display area AA2 are arranged following the same arrangement rule.

[0115] In this implementation, the numbers of the second closed openings 302 included in different touch electrode groups at different positions are substantially the same, thereby ensuring touch uniformity; in addition, the difficulty of forming the second closed openings 302 can be reduced.

[0116] In some embodiments, Figure 6 As shown, the display panel 001 further includes a dummy electrode 30', which can be located in the touch layer 03. Then, the dummy electrode 30' can be located in the same conductive film layer as the touch electrode 30. The dummy electrode 30' is electrically insulated from the touch electrode 30, and at least part of the dummy electrode 30' is located between the adjacent first touch electrode 30a and the second touch electrode 30b. The dummy electrode 30' located between the first touch electrode 30a and the second touch electrode 30b can effectively reduce the risk of short circuit between the first touch electrode 30a and the second touch electrode 30b; in addition, the dummy electrode 30' can be used as an electrostatic sacrificial point to absorb static electricity, so as to reduce the influence of static electricity on the first touch electrode 30a and the second touch electrode 30b.

[0117] Fig.21 for Figure 6 Schematic diagram of the local details corresponding to the R2 area.

[0118] like Fig.21 As shown, the dummy electrode 30' includes electrode lines 32, and the electrode lines 32 cross to form openings 300; at least some of the openings 300 corresponding to the dummy electrodes 30' include a third closed opening 303, and at least some of the openings 300 corresponding to the dummy electrodes 30' include a fourth closed opening 304. In the direction perpendicular to the plane where the substrate 01 is located, the third closed opening 303 at least partially overlaps with the sub-pixel 20, and the fourth closed opening 304 does not overlap with the sub-pixel 20.

[0119] In order to avoid the influence of the dummy electrode 30' on the light emitted by the sub-pixel 20, the dummy electrode 30' is a grid-like structure including electrode lines 32, and the electrode lines 32 cross to form a third closed opening 303. In the embodiment of the present application, the electrode lines 32 in the dummy electrode 30' not only cross to form the third closed opening 303 overlapping with the sub-pixel 20, but also form a fourth closed opening 304 that does not overlap with the sub-pixel 20. The electrode lines 32 outside the fourth closed opening 304 cross to form a closed structure, which means that the electrode lines 32 in the dummy electrode 30' have more cross-connected positions, thereby reducing the impedance of the touch electrode 30, and thus absorbing more static electricity.

[0120] It should be noted that the electrode lines 32 around the third closed opening 303 form a closed structure and the electrode lines 32 around the fourth closed opening 304 form a closed structure; in addition, the electrode lines 32 in the dummy electrodes 30 ′ and the touch lines 31 in the touch electrodes 30 may have the same line width.

[0121] It should also be noted that the dummy electrode 30' can be prepared at the same time as the touch electrode 30, and the design of the third closed opening 303 and the fourth closed opening 304 in the dummy electrode 30' can be the same as the first closed opening 301 and the second closed opening 302. For example, at least part of the fourth closed opening 304 overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located, the fourth closed opening 304 located in the first display area AA1 overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located, and the fourth closed opening 304 located in the second display area AA2 overlaps with the shading structure 51 in the black matrix in a direction perpendicular to the plane where the substrate 01 is located. The design of the dummy electrode 30' and the third closed opening 303 and the fourth closed opening 304 will not be repeated here.

[0122] Fig. 22 A partial schematic diagram of a display panel provided in an embodiment of the present application.

[0123] In some embodiments of the present application, when the first touch electrode group 3a includes the first touch electrode 30a and the first connection pattern 300a electrically connected thereto, as shown in FIG. Fig. 22 As shown, the first connection pattern 300 a includes touch lines 31 , and the touch lines 31 included in the first connection pattern 300 a cross to form a plurality of openings 300 . The plurality of openings 300 corresponding to the first connection pattern 300 a include a first closed opening 301 and a second closed opening 302 .

[0124] In order to avoid the influence of the first connection pattern 300a on the light emitted by the sub-pixel 20, the first connection pattern 300a is a grid-like structure including touch lines 31 and the touch lines 31 cross to form a first closed opening 301. In the embodiment of the present application, the touch lines 31 in the first connection pattern 300a not only cross to form the first closed opening 301 overlapping with the sub-pixel 20, but also form a second closed opening 302 that does not overlap with the sub-pixel 20. The touch lines 31 outside the second closed opening 302 cross to form a closed structure, which means that the touch lines 31 in the first connection pattern 300a have more cross-connection positions, thereby reducing the impedance of the first connection pattern 300a and reducing the impedance between the electrically connected first touch electrodes 30a.

[0125] It should be noted that the fact that the plurality of openings 300 corresponding to the first connection pattern 300a include the first closed opening 301 and the second closed opening 302 does not mean that any first connection pattern 300a must include both the first closed opening 301 and the second closed opening 302. In some implementations, some of the first connection patterns 300a include the first closed opening 301 and some of the first connection patterns 300a include the second closed opening 302. In some implementations, at least some of the first connection patterns 300a include both the first closed opening 301 and the second closed opening 302.

[0126] It should also be noted that the design of the first closed opening 301 and the second closed opening 302 in the first connection pattern 300a can be the same as the first closed opening 301 and the second closed opening 302 in the touch electrode 30. For example, at least part of the second closed opening 302 in the first connection pattern 300a overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located, the second closed opening 302 located in the first display area AA1 overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located, and the second closed opening 302 located in the second display area AA2 overlaps with the light shielding structure 51 in the black matrix in a direction perpendicular to the plane where the substrate 01 is located. The design of the first closed opening 301 and the second closed opening 302 in the first connection pattern 300a will not be repeated here.

[0127] In addition, if Fig. 22 As shown, when the second touch electrode group 3b includes the second touch electrode 30 and the second connection pattern 300b electrically connected thereto, as shown in FIG. Fig. 22 As shown, the second connection pattern 300 b includes touch lines 31 , and the touch lines 31 included in the second connection pattern 300 b cross to form a plurality of openings 300 . The plurality of openings 300 corresponding to the second connection pattern 300 b include a first closed opening 301 and a second closed opening 302 .

[0128] In order to avoid the influence of the second connection pattern 300b on the light emitted by the sub-pixel 20, the second connection pattern 300b is a grid-like structure including touch lines 31 and the touch lines 31 cross to form a first closed opening 301. In the embodiment of the present application, the touch lines 31 in the second connection pattern 300b not only cross to form the first closed opening 301 overlapping with the sub-pixel 20, but also form a second closed opening 302 that does not overlap with the sub-pixel 20. The touch lines 31 outside the second closed opening 302 cross to form a closed structure, which means that the touch lines 31 in the second connection pattern 300b have more cross-connection positions, thereby reducing the impedance of the second connection pattern 300b and reducing the impedance between the electrically connected second touch electrodes 30b.

[0129] It should be noted that the fact that the plurality of openings 300 corresponding to the second connection pattern 300b include the first closed opening 301 and the second closed opening 302 does not mean that any second connection pattern 300b must include both the first closed opening 301 and the second closed opening 302. In some implementations, some of the second connection patterns 300b include the first closed opening 301 and some of the second connection patterns 300b include the second closed opening 302. In some implementations, at least some of the second connection patterns 300b include both the first closed opening 301 and the second closed opening 302.

[0130] It should also be noted that the design of the first closed opening 301 and the second closed opening 302 in the second connection pattern 300b can be the same as the first closed opening 301 and the second closed opening 302 in the touch electrode 30. For example, at least part of the second closed opening 302 in the second connection pattern 300b overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located, the second closed opening 302 located in the first display area AA1 overlaps with the optical detection area LA in a direction perpendicular to the plane where the substrate 01 is located, and the second closed opening 302 located in the second display area AA2 overlaps with the light shielding structure 51 in the black matrix in a direction perpendicular to the plane where the substrate 01 is located. The design of the first closed opening 301 and the second closed opening 302 in the second connection pattern 300b will not be repeated here.

[0131] Fig.23 A partial schematic diagram of a display panel provided in an embodiment of the present application.

[0132] In some embodiments of the present application, Fig.23, the first connection pattern 300a and the first touch electrode 30a, the second touch electrode 30b, and the second connection pattern 300b are located in different conductive film layers. For example, the first touch electrode 30a, the second touch electrode 30b, and the second connection pattern 300b are all located on a side of the conductive film layer where the first connection pattern 300 is located away from the substrate 01; further, the first touch electrode 30a, the second touch electrode 30b, and the second connection pattern 300b are located in the same conductive film layer.

[0133] Along the direction perpendicular to the plane of substrate 01, combined Fig.23 , the first connection pattern 300a partially overlaps with the first touch electrode 30a, and the first connection pattern 300a at least partially overlaps with the second connection pattern 300b, then the intersection position of the first electrode group 3a and the second electrode group 3b is actually the intersection of the first connection pattern 300a and the second connection pattern 300b located in different conductive film layers.

[0134] In these embodiments, the first connection pattern 300a includes touch lines 31 and the touch lines 31 included in the first connection pattern 300a cross to form a plurality of virtual openings 300', wherein the projection of the virtual openings 300' on the substrate 01 is a closed shape and the touch lines 31 corresponding to the outer edges of the closed shape are partly the touch lines 31 in the first connection pattern 300a and partly the touch lines 31 in the second connection pattern 300b. That is, the touch lines 31 belonging to the first connection pattern 300a and the touch lines 31 belonging to the second connection pattern 300b extend in different directions in different conductive film layers to form the virtual openings 300', and the touch lines 31 belonging to the first connection pattern 300a and the touch lines belonging to the second connection pattern 300b in the virtual openings 300' are not connected, but their projections on the substrate 01 form a closed shape.

[0135] In the direction perpendicular to the plane where the substrate 01 is located, the virtual openings 300' corresponding to the first connection pattern 300a and the second connection pattern 300b overlap with the sub-pixel 20, and the virtual openings 300' can prevent the first connection pattern 300a and the second connection pattern 300b from blocking the sub-pixel 20 and affecting its light emission. In addition, the first connection pattern 300a and the second connection pattern 300b do not constitute an opening that does not overlap with the sub-pixel 202, thereby avoiding an increase in the number of overlaps between the touch lines 31 in the first connection pattern 300a and the touch lines 31 in the second connection pattern 300b, and also avoiding excessive occupation of the touch lines 31 in the first connection pattern 300a and the second connection pattern 300b, and reducing the probability of an increase in the misalignment area of ​​the first connection pattern 300a and the second connection pattern 300b due to process errors.

[0136] In some embodiments of the present application, the touch lines 31 outside the first closed opening 301 are located in the same conductive film layer, and the touch lines outside the second closed opening 302 are located in the same conductive film layer.

[0137] Fig.24 A partial schematic diagram of a display panel provided in an embodiment of the present application, Fig.25 for Fig.24 Schematic diagram of the cross section along the F1-F2 direction.

[0138] In some embodiments of the present application, Fig.24 and Fig.25 As shown, the plurality of second closed openings 302 include at least a first sub-opening 302a; the first sub-opening 302a overlaps the optical detection area LA along a direction perpendicular to the plane where the substrate 01 is located. The touch line 31 that crosses to form the first sub-opening 302a includes a first portion 311 and a second portion 312, and the first portion 311 and the second portion 312 are located in different conductive film layers.

[0139] In an implementation method corresponding to these embodiments, as Fig.24 and Fig.25 As shown, along the direction perpendicular to the plane where the substrate 01 is located, the first portion 311 and the second portion 312 at least partially overlap. Then, along the direction perpendicular to the plane where the substrate 01 is located, the at least partially overlapping first portion 311 and second portion 312 can enhance the collimation effect of the first sub-opening 302.

[0141] The present application embodiment provides a display device 002, such as Fig.26 As shown, the display device 002 includes a display panel 001 as provided in any of the above embodiments. The display device 002 provided in the embodiment of the present application may be an electronic device such as a mobile phone, a computer, a television, a vehicle-mounted display device, etc. The embodiment of the present application does not make any specific limitation.

[0142] In the display device 002 provided in the embodiment of the present application, the touch lines 31 of the touch electrodes 30 not only cross to form a first closed opening 301 that overlaps with the sub-pixel 20, but also form a second closed opening 302 that does not overlap with the sub-pixel 20. The touch lines 31 outside the second closed opening 302 cross to form a closed structure, which increases the cross-connection positions of the touch lines 31 in the touch electrodes 30, thereby reducing the impedance of the touch electrodes 30 and the reliability of the cross-connection of the touch lines 31 in the touch electrodes 30.

[0143] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
