Description

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] Organic Light Emitting Diode (OLED) and flat-panel display devices based on technologies such as Light Emitting Diode (LED) have been widely used in various consumer electronic products such as mobile phones, televisions, laptops, and desktop computers due to their advantages of high image quality, power saving, thin body and wide range of applications, becoming the mainstream of display devices. In the traditional display panel preparation process, the graphic formation of luminous pixels is usually achieved through a fine mask (FMM). FMM technology is mature and has rich experience in mass production. However, FMM technology also has problems such as limited precision, high development cost and long development cycle. Maskless technology eliminates the limitations of traditional OLED processes on display size, resolution and other screen performance, and has the advantages of high performance, full-area size and agile delivery.

[0085] In the drawings of this application, the X direction in the drawings may represent the first direction X, the Y direction in the drawings may represent the second direction Y, and the Z direction in the drawings may represent the thickness direction Z of the display panel 10. The first direction X, the second direction Y, and the thickness direction Z of the display panel 10 intersect with each other. For example, the first direction X, the second direction Y, and the thickness direction Z of the display panel 10 may be perpendicular to each other. The black dots at the intersections between the connecting traces TL and the sub-electrodes 500 in the drawings represent the electrical connection locations between the connecting traces TL and the sub-electrodes 500. For ease of illustration, dashed lines are used in some drawings to illustrate the outlines of the functional structures FS.

[0086] In order to facilitate the display of the isolation structure 300, the light-emitting device 400, the touch electrode, the connecting trace TL and the functional structure FS in the various drawings of the present application, the schematic number of the isolation opening 300a, the light-emitting device 400, the accommodating opening 300b, the touch electrode, the connecting trace TL and the functional structure FS is reduced in the drawings. Therefore, the drawings only serve as structural schematics and cannot represent the actual accurate structure of the display panel 10.

[0087] like Figures 1 to 3 As shown, an embodiment of the first aspect of the present application provides a display panel 10, comprising: a substrate 100; an isolation structure 300, disposed on one side of the substrate 100, the isolation structure 300 enclosing an isolation opening 300a and a receiving opening 300b; a light-emitting device 400, wherein at least a portion of the structure of the light-emitting device 400 is located within the isolation opening 300a; a touch electrode, disposed on one side of the substrate 100, the touch electrode comprising a plurality of sub-electrodes 500 extending along a first direction X, wherein the first direction X intersects with a thickness direction Z of the display panel 10, and a gap space 500a is provided between adjacent sub-electrodes 500 in the first direction X, and the sub-electrodes 500 are disposed within the receiving opening 300b; a functional structure FS, wherein at least a portion of the functional structure FS is located on a side of the gap space 500a facing the substrate 100, and an orthographic projection of the functional structure FS on the substrate 100 at least covers an orthographic projection of the gap space 500a on the substrate 100.

[0088] In a display panel 10 provided in an embodiment of the present application, the display panel 10 includes a substrate 100 , an isolation structure 300 , a light-emitting device 400 , a touch electrode, and a functional structure FS.

[0089] Optionally, there are various ways to dispose the substrate 100. Exemplarily, the substrate 100 includes a planarization layer 160 and a substrate 110 disposed on a side of the planarization layer 160 facing away from the touch electrodes.

[0090] Optionally, the substrate 100 further includes a driving circuit 150 disposed between the planarization layer 160 and the substrate 110. For example, the driving circuit 150 may include a transistor 151, a storage capacitor 152, and signal lines for connecting various devices. The transistor 151 may include a semiconductor, a gate 151a, and a source / drain 151b. The storage capacitor 152 may include a first plate 152a and a second plate 152b.

[0091] Optionally, the substrate 100 may further include a first insulating layer 120, a second insulating layer 130, and a third insulating layer 140, which are disposed between the substrate 110 and the planarization layer 160 and are sequentially stacked in a direction away from the substrate 110. As an example, the gate 151a and the first electrode 152a may be located on a side of the first insulating layer 120 facing the substrate 110, the second electrode 152b may be located between the first insulating layer 120 and the second insulating layer 130, and the source and drain 151b may be located between the second insulating layer 130 and the third insulating layer 140.

[0092] The isolation structure 300 encloses an isolation opening, and at least part of the structure of the light-emitting device 400 is located in the isolation opening 300a. The isolation structure 300 can be used to participate in dividing the sub-pixels of the display panel 10, and the light-emitting device 400 can be used to realize the light-emitting display of the display panel 10.

[0093] Illustratively, in a direction away from the substrate 100 , the light emitting device 400 includes a first electrode 410 , a light emitting functional layer 420 and a second electrode 430 stacked in sequence.

[0094] Optionally, the light-emitting functional layer 420 may include a hole injection layer (HIL), a hole transport layer (HTL), a light-emitting structure, an electron injection layer (EIL) and an electron transport layer (ETL).

[0095] Optionally, the first electrode 410 and the second electrode 430 can serve as pixel electrodes of the display panel 10. One of the first electrode 410 and the second electrode 430 can serve as an anode, and the other can serve as a cathode to drive the light-emitting functional layer 420 to emit light. In the embodiment of the present application, the first electrode 410 is used as the anode of the display panel 10, and the second electrode 430 is used as the cathode of the display panel 10.

[0096] Optionally, the display panel 10 further includes an encapsulation layer disposed on a side of the light-emitting device 400 facing away from the substrate 100. Exemplarily, in a direction away from the substrate 100, the encapsulation layer may include a first encapsulation layer, a second encapsulation layer, and a third encapsulation layer stacked sequentially. The materials of the first encapsulation layer and the third encapsulation layer may include inorganic materials and may be prepared by a chemical vapor deposition (CVD) process. The material of the second encapsulation layer may include an organic material and may be prepared by an inkjet printing (IJP) process.

[0097] The touch electrodes are disposed on one side of the substrate 100 and can be used to implement touch control on the display panel 10. The touch electrodes include a plurality of sub-electrodes 500 extending along a first direction X, with gaps 500a between adjacent sub-electrodes 500 in the first direction X. The sub-electrodes 500 arranged in the first direction X can implement touch control at different locations on the display panel 10.

[0098] Optionally, the display panel 10 may have multiple touch areas TA. In the display panel 10, the touch areas TA may be used as units to implement touch control of the display panel 10, so as to facilitate the control of touch electrodes in the display panel 10. For example, the touch areas TA may be arranged in an array in the first direction X and the second direction Y, that is, at least two touch areas TA may be arranged in the first direction X at intervals, and at least two touch areas TA may be arranged in the second direction Y at intervals.

[0099] Optionally, the sub-electrodes 500 arranged in the first direction X can be used to implement touch operations at different touch areas TA in the display panel 10. For example, each sub-electrode 500 arranged in the first direction X can be located in a different touch area TA. That is, each sub-electrode 500 arranged in the first direction X is located in a different touch area TA, so that each sub-electrode 500 arranged in the first direction X can be used to implement touch operations at different touch areas TA in the display panel 10. The gap spaces 500a provided between adjacent sub-electrodes 500 in the first direction X facilitate insulation of the sub-electrodes 500 between adjacent touch areas TA in the first direction X.

[0100] Optionally, there are multiple gap spaces 500 a , which is beneficial for dividing a larger number of touch areas TA, thereby facilitating improving the touch effect of the display panel 10 .

[0101] By providing an isolation structure 300 to enclose a receiving opening 300 b and providing the sub-electrode 500 in the receiving opening 300 b , it is unnecessary to provide an additional layer structure above the isolation structure 300 to arrange the sub-electrode 500 , thereby enabling the display panel 10 to have a smaller thickness.

[0102] By arranging at least part of the functional structure FS to be located on the side of the gap space 500a facing the substrate 100, and arranging the orthographic projection of the functional structure FS on the substrate 100 to cover at least part of the orthographic projection of the gap space 500a on the substrate 100, the functional structure FS can be used to adjust the light reflectivity at the corresponding position of the gap space 500a, so that the light reflection effect of the display panel 10 at the corresponding position of the gap space 500a is greatly different from the light reflection effect at the corresponding position of the sub-electrode 500, so that when the display panel 10 is in the off-screen state, the gap space 500a between the sub-electrodes 500 arranged in the first direction X is not easily observed, which is beneficial to reducing the appearance difference of the display panel 10 in the off-screen state, and is beneficial to improving the appearance effect of the display panel 10 in the off-screen state.

[0103] Optionally, the orthographic projection of the gap space 500a on the substrate 100 can be located within the orthographic projection of the functional structure FS on the substrate 100, so that the functional structure FS can have a larger size, which can better enhance the regulating effect of the functional structure FS on the light reflectivity at the corresponding position of the gap space 500a.

[0104] Optionally, the orthographic projection of the gap space 500 a on the substrate 100 may refer to the orthographic projection of the area facing each other between the adjacent sub-electrodes 500 in the first direction X on the substrate 100 .

[0105] Optionally, at least two gap spaces 500a are spaced apart in the first direction X, the number of functional structures FS is multiple, and at least two functional structures FS are spaced apart in the first direction X, so that the functional structures FS spaced apart in the first direction X can be used to adjust the light reflectivity at the corresponding positions of each gap space 500a spaced apart in the first direction X.

[0106] Optionally, the first direction X may be the row arrangement direction of the sub-electrodes 500, that is, the sub-electrodes 500 spaced apart in the first direction X may be located in the same row. At least two gap spaces 500a spaced apart in the first direction X may mean that the sub-electrodes 500 corresponding to the at least two gap spaces 500a are located in the same row in the first direction X.

[0107] In some optional embodiments, at least two sub-electrodes 500 are spaced apart in the second direction Y, which is beneficial to improving the arrangement density of the sub-electrodes 500, thereby improving the touch effect of the display panel 10. For example, at least two sub-electrodes 500 spaced apart in the second direction Y may be provided in a single touch area TA, thereby improving the arrangement density of the sub-electrodes 500 in the single touch area TA.

[0108] Optionally, at least two adjacent sub-electrodes 500 in the second direction Y may be electrically connected to each other to facilitate control of the sub-electrodes 500. For example, the sub-electrodes 500 located in the same touch area TA may be electrically connected to each other to facilitate control of the sub-electrodes 500 in the touch area TA.

[0109] Optionally, the display panel 10 further includes a connecting line TL, and at least two adjacent sub-electrodes 500 in the second direction Y may be electrically connected via the connecting line TL. For example, touch electrodes located in the same touch area TA are electrically connected via the connecting line TL, and touch electrodes located in different touch areas TA may be insulated from each other. This facilitates control of the sub-electrodes 500 within a single touch area TA while also reducing signal crosstalk between the sub-electrodes 500 in adjacent touch areas TA.

[0110] Optionally, the connecting line TL may extend along the second direction Y, so that a single connecting line TL is electrically connected to at least two adjacent sub-electrodes 500 in the second direction Y.

[0111] Optionally, there are multiple connecting lines TL, and the multiple connecting lines TL can be spaced apart in the first direction X, so that the sub-electrodes 500 in different touch areas TA can be electrically connected to different connecting lines TL spaced apart in the first direction X.

[0112] Optionally, the sub-electrodes 500 located in the same touch area TA may be electrically connected via multiple or a single connection line TL. For ease of description, the following embodiments will be described using the example of the sub-electrodes 500 located in the same touch area TA being electrically connected via a single connection line TL.

[0113] Optionally, the connecting trace TL can be used to connect to the touch key integrated circuit 20 (Touch Key IC), so that the touch electrode can be electrically connected to the touch chip 20 through the connecting trace TL. The touch chip 20 can detect the capacitance change on the touch electrode located at the corresponding position in the display panel 10 through the connecting trace TL for identification and positioning, thereby realizing touch display of the display panel 10.

[0114] In some optional embodiments, the display panel 10 provided in the embodiments of the present application may be a display panel 10 that realizes touch positioning based on a self-capacitive touch architecture, that is, the touch electrode can be specifically used as an excitation and detection electrode. When a finger touches the display panel 10 as a conductor, the capacitance of the sub-electrode 500 in the touch area TA at the corresponding position increases, so that identification and positioning can be performed through capacitance changes, thereby realizing touch display of the display panel 10.

[0115] For example, when a finger, acting as a conductor, touches the display panel 10, the sub-electrodes 500 within the touch area TA at the corresponding position are affected by the finger and some charge is removed, causing a capacitance change. Here, Cp is the parasitic capacitance between the sub-electrode 500 and ground, and Cf is the induced capacitance between the sensing electrode and ground, generated by the human body when the finger touches the display panel 10. When the finger, acting as a conductor, touches the display panel 10, Cp and Cf are connected in parallel, resulting in parasitic capacitance = Cp + Cf. This increases the parasitic capacitance, allowing for identification and positioning through capacitance changes, thereby enabling touch display on the display panel 10.

[0116] When the touch electrodes can be specifically used as electrodes for excitation and detection, that is, when the display panel 10 is a display panel 10 that realizes touch positioning based on a self-capacitive touch architecture, there is no need to set corresponding driving electrodes for excitation and receiving electrodes for detection on the display panel 10. Only the touch electrodes are set to realize the touch function of the display panel 10, so that there is no need to set too many layer structures to arrange the electrodes for the touch function, so that the display panel 10 can have a smaller thickness.

[0117] In some optional embodiments, the isolation structure 300 includes a first isolation portion 310 and a second isolation portion 320 located on the side of the first isolation portion 310 facing away from the substrate 100, and the second isolation portion 320 is protruding from the first isolation portion 310 toward the isolation opening 300a and / or the accommodating opening 300b.

[0118] By arranging the second isolation portion 320 to protrude from the first isolation portion 310 toward the isolation opening 300a and / or the accommodating opening 300b, when vapor-depositing the light-emitting functional layer 420 and the second electrode 430 of the display panel 10, the second isolation portion 320 can block at least a portion of the material used to prepare the light-emitting functional layer 420 and the second electrode 430, so as to separate the light-emitting functional layer 420 and the second electrode 430 between adjacent sub-pixels, and can facilitate the formation of multiple spaced light-emitting functional layers 420 and second electrodes 430, so that when vapor-depositing the light-emitting functional layer 420 and the second electrode 430 of the display panel 10, there is no need to set a mask with high precision, for example, when vapor-depositing the light-emitting functional layer 420 and the second electrode 430, there is no need to set a high-precision metal mask (Fine Metal Mask, FMM), thereby effectively reducing the production cost of the display panel 10.

[0119] Optionally, the material of the isolation structure 300 may include a conductive material, the sub-electrode 500 may be insulated from the isolation structure 300, and the second electrode 430 may be electrically connected to the isolation structure 300, so that the second electrodes 430 of adjacent light-emitting devices 400 can be electrically connected through the isolation structure 300, thereby facilitating control of the second electrodes 430. For example, the material of the first isolation portion 310 may include a conductive material, and the second electrode 430 may be connected to the first isolation portion 310, so that the second electrodes 430 of adjacent light-emitting devices 400 can be electrically connected through the first isolation portion 310.

Optionally, the second electrode 430 may be connected to the conductive portion 330 .

[0121] By arranging the conductive portion 330 to protrude from the first isolation portion 310 toward the isolation opening 300a and / or the accommodating opening 300b, the overlap between the second electrode 430 and the conductive portion 330 can be facilitated, and the overlap area between the second electrode 430 and the conductive portion 330 can be better increased, thereby better reducing the resistance of the display panel 10.

[0124] Optionally, the second touch portion 520 is disposed to protrude from the first touch portion 510 toward the isolation structure 300 .

[0125] In these optional embodiments, by setting the first touch portion 510 and the first isolation portion 310 to be in the same layer and material, and the second touch portion 520 and the second isolation portion 320 to be in the same layer and material, and setting the shape of the sub-electrode 500 to be similar to the shape of the isolation structure 300, the first touch portion 510 in the sub-electrode 500 and the first isolation portion 310 in the isolation structure 300 can be prepared in the same preparation step using the same or similar preparation equipment, and the second touch portion 520 in the sub-electrode 500 and the second isolation portion 320 in the isolation structure 300 can be prepared in the same preparation step using the same or similar preparation equipment, thereby greatly improving the preparation efficiency of the display panel 10.

[0129] In some optional embodiments, the display panel 10 further includes a pixel definition layer 200 located on one side of the substrate 100 . The pixel definition layer 200 may have a pixel opening 200 a connected to the isolation opening 300 a . The pixel definition layer 200 may also be used to divide the sub-pixels of the display panel 10 .

[0130] Optionally, the light emitting device 400 may be partially located in the pixel opening 200a. For example, a portion of the light emitting device 400 may be located in the pixel opening 200a, and another portion of the light emitting device 400 may extend out of the pixel opening 200a and be located in the isolation opening 300a.

[0131] Optionally, the isolation structure 300 and the sub-electrode 500 may both be disposed on the side of the pixel definition layer 200 facing away from the substrate 100 , which can reduce interference effects of signals in the underlying film structure on signals in the isolation structure 300 and the touch electrodes.

[0132] In some optional embodiments, the accommodating opening 300 b extends along the first direction X, and at least two adjacent sub-electrodes 500 in the first direction X are located in the same accommodating opening 300 b.

[0133] Optionally, the isolation structure 300 may not be located between two sub-electrodes 500 spaced apart in the first direction X, that is, the isolation structure 300 may not be located in the gap space 500 a .

[0134] In these optional embodiments, by arranging at least two adjacent sub-electrodes 500 in the first direction X to be located within the same receiving opening 300 b , adjacent sub-electrodes 500 in the first direction X can be spaced closer together, i.e., the gap space 500 a can be smaller in the first direction X, thereby facilitating an increase in the arrangement density of the sub-electrodes 500 in the first direction X. Furthermore, the isolation structure 300 does not need to extend into the gap space 500 a , allowing the isolation structure 300 to have a desired width, thereby facilitating the fabrication of the isolation structure 300 .

[0136] Optionally, at least part of the isolation opening 300 a is located between adjacent receiving openings 300 b in the second direction Y.

[0137] In these optional embodiments, by arranging adjacent sub-electrodes 500 in the second direction Y in different accommodating openings 300b, it is possible to facilitate the arrangement of isolation openings 300a between adjacent sub-electrodes 500 in the second direction Y, thereby facilitating the arrangement of the light-emitting devices 400, so that a larger number of light-emitting devices 400 can be arranged in the second direction Y, which is beneficial to improving the pixel density (Pixels Per Inch, PPI) of the display panel 10.

[0138] Figure 4 1 is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application. Figure 4 Can Figure 2 Schematic cross-section at the middle BB position.

[0139] In some embodiments of the present application, there are multiple ways to set the position of the functional structure FS.

[0140] In some optional embodiments, the functional structure FS may be disposed in the substrate 100 .

[0141] Optionally, the functional structure FS may be disposed between the planarization layer 160 and the substrate 110 . For example, the functional structure FS may be disposed between any two layers of the substrate 110 , the first insulating layer 120 , the second insulating layer 130 , the third insulating layer 140 , and the planarization layer 160 .

[0142] In these optional embodiments, by setting the functional structure FS in the substrate 100, the thickness of the display panel 10 is reduced, and during the preparation process of the display panel 10, the functional structure FS can be prepared together with the devices in the substrate 100, which is beneficial to improving the preparation efficiency of the display panel 10.

[0143] In some optional embodiments, at least one functional structure FS is provided in the same layer and material as at least part of the film layer structure in the driving circuit 150 , or at least one film layer structure in the driving circuit 150 is reused as at least one functional structure FS.

[0144] Optionally, at least one film layer structure in the driving circuit 150 is reused as at least one functional structure FS, which may mean that at least one film layer structure in the driving circuit 150 can extend between the gap space 500a and the substrate 110 to serve as at least one functional structure FS.

[0145] Optionally, at least one functional structure FS can be set in the same layer and material as the film layer structure in the transistor 151 or the storage capacitor 152 (not shown in the figure), or at least part of the film layer structure in the transistor 151 or the storage capacitor 152 can be reused as at least one functional structure FS (not shown in the figure).

[0146] Optional, such as Figure 4 As shown, the driving circuit 150 further includes a power supply voltage signal line 153, and at least one functional structure FS is provided on the same layer and material as the power supply voltage signal line 153, or at least a portion of the power supply voltage signal line 153 is multiplexed into the at least one functional structure FS. Exemplarily, the driving circuit 150 may include a positive power supply voltage signal line 153, and at least one functional structure FS may be provided on the same layer and material as the positive power supply voltage signal line 153, or at least a portion of the positive power supply voltage signal line 153 is multiplexed into the at least one functional structure FS.

[0147] Among them, by setting at least part of the positive power supply voltage signal line 153 to be multiplexed as at least one functional structure FS, that is, by setting at least part of the positive power supply voltage signal line 153 to extend between the gap space 500a and the substrate 110 to serve as at least one functional structure FS, the positive power supply voltage signal line 153 with a wider width can be used to adjust the light reflectivity at the corresponding position of the gap space 500a, which can further help reduce the appearance difference of the display panel 10 in the off state, and help improve the appearance effect of the display panel 10 in the off state.

[0151] Figure 5 1 is a partial cross-sectional view of a display panel 10 provided in another embodiment of the present application. Figure 5 Can Figure 2 Schematic cross-section at the center CC position.

[0152] In some embodiments of the present application, there are various ways to position the connection line TL. The connection line TL can be set on the side of the sub-electrode 500 facing away from the substrate 100 (not shown in the figure), or as shown in FIG. Figure 5 As shown, the connection trace TL can be disposed on the side of the sub-electrode 500 facing the substrate 100. For ease of description, the following embodiments are described by taking the example of the connection trace TL being disposed on the side of the sub-electrode 500 facing the substrate 100.

[0153] In some optional embodiments, the connecting traces TL may be disposed within the substrate 100 .

[0154] Optionally, the connection line TL may be disposed between the planarization layer 160 and the substrate 110 . For example, the connection line TL may be disposed between any two layers among the substrate 110 , the first insulating layer 120 , the second insulating layer 130 , the third insulating layer 140 and the planarization layer 160 .

[0155] Optionally, the connection trace TL may be provided in the same layer and the same material as at least a portion of the film structure in the driving circuit 150 .

[0156] In these optional embodiments, by setting the connecting traces TL in the substrate 100, the thickness of the display panel 10 is reduced, and during the preparation process of the display panel 10, the connecting traces TL can be prepared together with the devices in the substrate 100, which is beneficial to improving the preparation efficiency of the display panel 10.

[0157] In some optional embodiments, at least one functional structure FS and the connecting trace TL are provided on the same layer and made of the same material.

[0158] Exemplarily, both the functional structure FS and the connecting trace TL may be disposed between the third insulating layer 140 and the planarization layer 160 .

[0159] Optionally, the connecting trace TL is located between adjacent functional structures FS.

[0160] In these optional embodiments, by setting at least one functional structure FS and the connecting trace TL in the same layer and material, the connecting trace TL and the functional structure FS can be prepared together during the preparation process of the display panel 10, which is beneficial to improving the preparation efficiency of the display panel 10.

[0161] In some optional embodiments, a single functional structure FS is located on at least one side of at least two gap spaces 500 a in the thickness direction Z of the display panel 10 .

[0162] Optionally, the functional structure FS may extend along the second direction Y, and a single functional structure FS extends through at least one side of at least two gap spaces 500 a in the thickness direction Z of the display panel 10 .

[0163] Optionally, at least two gap spaces 500a are spaced apart in the second direction Y. The at least two gap spaces 500a are spaced apart in the second direction Y, which may mean that a virtual line DL between the at least two gap spaces 500a arranged in the second direction Y may extend along the second direction Y, that is, the projections of the at least two gap spaces 500a in the second direction Y at least partially overlap.

[0164] Optionally, the virtual lines DL between certain gap spaces 500a described in the embodiments of the present application may refer to virtual lines DL extending through certain gap spaces 500a, where the virtual lines DL are straight lines. For example, the virtual lines DL between certain gap spaces 500a described in the embodiments of the present application may refer to virtual lines DL extending through the geometric centers of certain gap spaces 500a, where the virtual lines DL are straight lines.

[0165] In these optional embodiments, by arranging a single functional structure FS on at least one side of at least two gap spaces 500a in the thickness direction Z of the display panel 10, the single functional structure FS can simultaneously adjust the light reflectivity at the corresponding positions of at least two gap spaces 500a, which is beneficial to improving the utilization efficiency of the functional structure FS.

[0166] Figure 6 3 is a partial structural diagram of an isolation structure 300 , a connecting trace TL, a touch electrode, and a functional structure FS according to another embodiment of the present application.

[0167] like Figure 6 As shown, in some optional embodiments, the extension direction of the virtual line DL between at least two gap spaces 500a intersects both the first direction X and the second direction Y.

[0168] Optionally, projections of at least two adjacent gap spaces 500a in the second direction Y in the second direction Y do not overlap.

[0169] Optionally, at least two adjacent gap spaces 500a in the second direction Y have a distance in the first direction X, so that the extension direction of the virtual line DL between the at least two gap spaces 500a intersects both the first direction X and the second direction Y.

[0170] Optionally, there are various ways to set the specific value of the distance between at least two adjacent gap spaces 500a in the second direction Y in the first direction X. The specific value of the distance between at least two adjacent gap spaces 500a in the second direction Y in the first direction X can be set based on the fact that it is difficult to observe nearly connected lines between the gap spaces 500a in the display panel 10 in the off state in the second direction Y. For example, the distance between at least two adjacent gap spaces 500a in the second direction Y in the first direction X can be greater than the size of a single isolation opening 300a in the first direction X.

[0171] Optionally, the projections of at least two adjacent sub-electrodes 500 in the second direction Y are arranged to be incompletely overlapped in the second direction Y, so that the extension direction of the virtual line DL between the at least two gap spaces 500a intersects both the first direction X and the second direction Y.

[0172] In these optional embodiments, by setting the extension direction of the virtual line DL between at least two gap spaces 500a to intersect with both the first direction X and the second direction Y, the gap spaces 500a arranged in the second direction Y are not likely to be too concentrated in the same column, that is, at least part of the gap spaces 500a can be staggered in the first direction X, so that when the display panel 10 is in the off-screen state, it is difficult to observe the almost connected lines of the gap spaces 500a in the second direction Y, which is beneficial to reducing the appearance difference of the display panel 10 in the off-screen state, and is beneficial to improving the appearance effect of the display panel 10 in the off-screen state.

[0173] Figure 7 3 is a partial structural diagram of an isolation structure 300 , a connecting trace TL, a touch electrode, and a functional structure FS according to yet another embodiment of the present application.

[0174] like Figure 6 and Figure 7 As shown, in some optional embodiments, a virtual line DL between at least one gap space 500a between the sub-electrodes 500 located in the i-th row and one of the gap spaces 500a between the sub-electrodes 500 located in the i+k-th row extends along the second direction Y, 2≤k≤8, and i and k are both positive integers.

[0175] Optional, such as Figure 6 As shown, when k>2, the extension direction of the virtual line DL between at least two gap spaces 500a between the sub-electrodes 500 in the i-th row to the (i+k-1)-th row intersects both the first direction X and the second direction Y. Exemplarily, when k>2, the projections of the gap spaces 500a between the sub-electrodes 500 in the i-th row to the (i+k-1)-th row in the second direction Y do not overlap.

[0176] In these optional embodiments, by reasonably setting the spacing positions between the gap spaces 500a arranged in the second direction Y, the number of adjacent sub-electrodes 500 in the second direction Y that are misaligned can be better controlled, so that the degree of misalignment of each sub-electrode 500 in a single touch area TA will not be too large, which is beneficial to the arrangement of the sub-electrodes 500 and can reduce the maximum size of a single touch area TA in the first direction X, thereby helping to improve the arrangement density of the touch area TA.

[0177] See also Figures 1 to 7The embodiment of the first aspect of the present application further provides a display panel 10, comprising: a substrate 100; and a touch electrode disposed on one side of the substrate 100, the touch electrode comprising a plurality of sub-electrodes 500 extending along a first direction X, with gap spaces 500a being provided between adjacent sub-electrodes 500 in the first direction X, wherein the number of gap spaces 500a is plural, at least two sub-electrodes 500 are spaced apart in a second direction Y, an extension direction of a virtual line DL between at least two gap spaces 500a intersects both the first direction X and the second direction Y, and the first direction X, the second direction Y intersect with the thickness direction Z of the display panel 10 in pairs.

[0178] In a display panel 10 provided in an embodiment of the present application, the display panel 10 includes a substrate 100, touch electrodes, and a functional structure FS. The touch electrodes are disposed on one side of the substrate 100 and can be used to implement touch control on the display panel 10. The touch electrodes include a plurality of sub-electrodes 500 extending along a first direction X, with gaps 500a between adjacent sub-electrodes 500 in the first direction X. The sub-electrodes 500 arranged in the first direction X can implement touch control at different locations on the display panel 10. At least two sub-electrodes 500 are spaced apart in a second direction Y, which helps increase the arrangement density of the sub-electrodes 500, thereby improving the touch performance of the display panel 10.

[0179] There are multiple gap spaces 500a. By setting the extension direction of the virtual line DL between at least two gap spaces 500a to intersect with both the first direction X and the second direction Y, the gap spaces 500a arranged in the second direction Y are not likely to be too concentrated in the same column, that is, at least part of the gap spaces 500a can be staggered in the first direction X, so that when the display panel 10 is in the off state, it is difficult to observe the almost connected lines of the gap spaces 500a in the second direction Y, which is beneficial to reducing the appearance difference of the display panel 10 in the off state and improving the appearance effect of the display panel 10 in the off state.

[0180] Optionally, the embodiment of the first aspect of the present application also provides a display panel 10 which may be the display panel 10 in any of the aforementioned embodiments.
