[0112] In an embodiment of the present application, each of the following embodiments can be applied to the display panel 10 provided in any one of the foregoing embodiments.

[0116] In these alternative embodiments, the first electrode layer 700 and the second electrode layer 200 may be pixel electrode layers of the display panel 10. One of the first electrode 710 and the second electrode 210 may serve as the anode, and the other may serve as the cathode to drive the light-emitting unit 510 to emit light. In the embodiments of the present application, it is exemplified that the first electrode 710 is the cathode of the display panel 10 and the second electrode 210 is the anode of the display panel 10.

[0117] In some alternative embodiments, such as Figure 3 shown, the isolation structure 300 may be in a grid shape, and the hollowed-out area in the grid-shaped isolation structure 300 may be an isolation opening 300a to facilitate the division of sub-pixels of the display panel 10.

[0118] Optionally, the light-emitting unit 510 may include a first light-emitting unit 510a, a second light-emitting unit 510b, and a third light-emitting unit 510c with different emission colors. For example, the first light-emitting unit 510a may be used to emit red light, the second light-emitting unit 510b may be used to emit green light, and the third light-emitting unit 510c may be used to emit blue light. The isolation opening 300a may include a first opening 300b, a second opening 300c, and a third opening 300d. The first opening 300b may be used to accommodate the first light-emitting unit 510a, the second opening 300c may be used to accommodate the second light-emitting unit 510b, and the third opening 300d may be used to accommodate the third light-emitting unit 510c.

[0119] Optionally, a part of the isolation structure 300 may be formed by extending along a first preset direction X, and a part of the isolation structure 300 may be formed by extending along a second preset direction Y, so that the isolation structure 300 can be intertwined to form a mesh.

[0120] In some alternative embodiments, the isolation structure 300 includes a first isolation part 310 and a second isolation part 320 located on the side of the first isolation part 310 away from the substrate 100. The orthographic projection of the first isolation part 310 on the substrate 100 is located within the orthographic projection of the second isolation part 320 on the substrate 100.

[0121] Optionally, the second isolation part 320 may protrude from the first isolation part 310 toward the isolation opening 300a.

[0122] In these optional embodiments, by setting the orthographic projection of the first isolation portion 310 on the substrate 100 to be within the orthographic projection of the second isolation portion 320 on the substrate 100, when the light-emitting layer 500 and the first electrode layer 700 of the display panel 10 are evaporated, the second isolation portion 320 can block at least a portion of the material used to prepare the light-emitting layer 500 and the first electrode layer 700, so as to separate the light-emitting layer 500 and the first electrode layer 700 between adjacent sub-pixels, and can facilitate the formation of a plurality of spaced light-emitting units 510 and the first electrode 710, so that when the light-emitting layer 500 and the first electrode 710 of the display panel 10 are evaporated, there is no need to set a mask with high precision, for example, when the light-emitting layer 500 and the first electrode 710 are evaporated, thereby reducing the production cost of the display panel 10.

[0123] Optionally, the material of the isolation structure 300 may include a conductive material. For example, the material of the first isolation portion 310 may include a conductive material. The first electrodes 710 in adjacent isolation openings 300a may be electrically connected through the isolation structure 300, so that the first electrodes 710 in adjacent isolation openings 300a may be interconnected through the first isolation portion 310 to form a surface electrode, so as to facilitate the control of the first electrode 710 in the display panel 10.

[0124] Optionally, the display panel 10 may further include a pixel definition layer 11 disposed on one side of the substrate 100. The pixel definition layer 11 may include a pixel defining portion 11a. At least a portion of the pixel defining portion 11a may be disposed between the isolation structure 300 and the second electrode 210, so that the second electrode 210 and the isolation structure 300 can be insulated by the pixel defining portion 11a, so that a short circuit is not easily generated between the second electrode 210 and the first electrode 710 through the isolation structure 300.

[0125] Optionally, the isolation structure 300 may be directly disposed on the substrate 100 to reduce the thickness of the display panel 10, or Figure 2 As shown, the isolation structure 300 may be disposed on the pixel defining portion 11 a . For ease of description, the following embodiments are described by taking the isolation structure 300 being disposed on the pixel defining portion 11 a as an example.

[0126] Optionally, the display panel 10 has a display area A1 and a border area A2, and each isolation structure 300 can extend from the display area A1 to the border area A2, so that the first electrode 710 in each isolation opening 300a can be electrically connected to the negative power supply voltage signal line located in the border area A2 through the isolation structure 300, so that the first electrode 710 in each isolation opening 300a can receive the negative power supply voltage signal (ELVSS) transmitted by the negative power supply voltage signal line.

[0127] In these alternative embodiments, by insulating the touch electrode 800 from the isolation structure 300, it is possible to prevent the signal in the first electrode 710 from easily generating crosstalk with the signal in the touch electrode 800 through the isolation structure 300. In some embodiments of the present application, there are various ways to insulate the touch electrode 800 from the isolation structure 300. For example, an insulating material can be provided between the isolation structure 300 and the touch electrode 800. Alternatively, the touch electrode 800 can be arranged at intervals from the isolation structure 300.

[0128] Optionally, the size of the touch electrode 800 in the thickness direction Z of the display panel 10 can be less than or equal to the size of the first electrode 710 in the thickness direction Z, so that it is not easy to generate a coupling electric field between the touch electrode 800 and the isolation structure 300, and further prevent the signal in the first electrode 710 from easily generating crosstalk with the signal in the touch electrode 800 through the isolation structure 300.

[0129] In some embodiments of the present application, to facilitate the extension of each isolation structure 300 from the display area A1 to the border area A2, there are various arrangement shapes of the accommodation gaps 301 between adjacent isolation structures 300.

[0130] In some alternative embodiments, the number of accommodation gaps 301 is at least two. At least two accommodation gaps 301 are formed to extend along the first preset direction X and are arranged at intervals in the second preset direction Y, and / or at least two accommodation gaps 301 are formed to extend along the second preset direction Y and are arranged at intervals in the first preset direction X, so that the isolation structure 300 can extend from the display area A1 to the border area A2 between two adjacent accommodation gaps 301.

[0131] In some embodiments, there can be multiple isolation openings 300a between adjacent accommodation gaps 301 to increase the arrangement density of the isolation openings 300a and reduce the influence of the arrangement of the accommodation gaps 301 on the light emission display of the display panel 10. Optionally, there are at least three isolation openings 300a between adjacent accommodation gaps 301. For example, there can be a first opening 300b, a second opening 300c, and a third opening 300d between adjacent accommodation gaps 301, so that there can be a first light-emitting unit 510a, a second light-emitting unit 510b, and a third light-emitting unit 510c with different emission colors between adjacent accommodation gaps 301, thereby enabling the display panel between adjacent accommodation gaps 301 to have a better light-emitting effect.

[0132] Optionally, the number of isolation openings 300a between adjacent accommodation gaps 301 can be a multiple of three, so that there can be multiple groups of first openings 300b, second openings 300c, and third openings 300d between adjacent accommodation gaps 301 to further improve the light-emitting display effect of the display panel 10.

[0133] Figure 4 It is a schematic structural diagram of a touch electrode 800 and a connection line S1 according to an embodiment of the present application.

[0134] As Figure 4 shown, in some alternative embodiments, the touch electrode 800 includes at least two spaced-apart touch units 810. The touch unit 810 includes at least two sub-electrodes 811 disposed in the accommodation gap 301. The display panel 10 further includes a connection line S1. The sub-electrodes 811 within the same touch unit 810 are electrically connected through the connection line S1, such that in the display panel 10, the touch unit 810 can be used as a unit to participate in implementing the touch operation of the display panel 10, facilitating the relevant control of the touch electrode 800 in the display panel 10.

[0135] In some embodiments of the present application, the display panel 10 can be a display panel 10 that realizes touch positioning based on a self-capacitance touch architecture. That is, the touch electrode 800 can be specifically used as an electrode for excitation and detection. When a finger touches the display panel 10 as a conductor, the capacitance on the sub-electrode 811 of the touch unit 810 at the corresponding position in the touch electrode 800 increases, enabling identification and positioning through the capacitance change, thereby realizing the touch display of the display panel 10.

[0136] For example, when a finger touches the display panel 10 as a conductor, the sub-electrode 811 of the touch unit 810 at the corresponding position will be affected by the finger and conduct a part of the charge, thereby causing a capacitance change. Among them, Cp is the parasitic capacitance between the sub-electrode 811 and the ground, and Cf is the inductive capacitance between the inductive electrode generated through the human body when the finger touches and the ground. When a finger touches the display panel 10 as a conductor, it is equivalent to the parallel connection of Cp and Cf, such that the parasitic capacitance = Cp + Cf, that is, the parasitic capacitance increases, enabling identification and positioning through the capacitance change, thereby realizing the touch display of the display panel 10.

[0137] When the touch electrode 800 can be specifically used as an electrode for excitation and detection, that is, when the display panel 10 is a display panel 10 that realizes touch positioning based on a self-capacitance touch architecture, there is no need to provide corresponding drive electrodes for excitation and receiving electrodes for detection on the display panel 10. Only by setting the touch electrode 800 can the touch function of the display panel 10 be realized, so that there is no need to set too many layer structures to arrange the electrodes for the touch function, enabling the display panel 10 to have a smaller thickness.

[0138] Figure 5 It is a schematic structural diagram of an isolation structure 300 and a touch electrode 800 according to another embodiment of the present application. Figure 6 It is a schematic structural diagram of a touch electrode 800 and a connection line S1 according to another embodiment of the present application.

[0139] Optionally, asFigures 3 to 6 As shown, at least two touch units 810 are arranged at intervals in the interval arrangement direction of the accommodation gap 301, and / or at least two touch units 810 are arranged at intervals in the extension direction of the accommodation gap 301, so as to facilitate the arrangement of the sub-electrodes 811 in the touch unit 810 within the accommodation gap 301. For example, as Figure 5 and Figure 6 shown, when at least two accommodation gaps 301 are formed by extending along the first preset direction X and arranged at intervals in the second preset direction Y, at least two touch units 810 can be arranged at intervals in the first preset direction X and / or at least two touch units 810 are arranged at intervals in the second preset direction Y, so that the display panel 10 can have relatively uniform and sufficient touch units 810 to realize the touch function.

[0140] In some embodiments of the present application, under the influence of the arrangement shape of the accommodation gap 301, there are also various arrangement methods for the corresponding sub-electrodes 811.

[0141] In some alternative embodiments, as Figures 3 to 6 shown, at least part of the sub-electrodes 811 are formed by extending along the extension direction of the accommodation gap 301, and / or at least two sub-electrodes 811 are arranged at intervals in the interval arrangement direction of the accommodation gap 301.

[0142] For example, as Figure 3 and Figure 4 shown, when at least two accommodation gaps 301 are formed by extending along the second preset direction Y and arranged at intervals in the first preset direction X, at least two sub-electrodes 811 are formed by extending along the second preset direction Y and arranged at intervals in the first preset direction X, and / or, as Figure 5 and Figure 6 shown, when at least two accommodation gaps 301 are formed by extending along the first preset direction X and arranged at intervals in the second preset direction Y, at least two sub-electrodes 811 are formed by extending along the first preset direction X and arranged at intervals in the second preset direction Y, so that the isolation structure 300 can extend from the display area A1 to the border area A2 between adjacent two sub-electrodes 811, making the arrangement of the isolation structure 300 not likely to interfere with the sub-electrodes 811.

[0143] Optionally, at least part of the connection lines S1 are formed by extending along the interval arrangement direction of the accommodation gap 301, and / or at least two connection lines S1 are arranged at intervals in the extension direction of the accommodation gap 301.

[0144] For example, as Figure 3 and Figure 4As shown, when at least two accommodating gaps 301 are formed to extend along the second preset direction Y and are spaced apart in the first preset direction X, at least a part of the connection line S1 can be formed to extend along the first preset direction X, and at least two connection lines S1 can be spaced apart in the second preset direction Y; as Figure 5 and Figure 6 shown, and when at least two accommodating gaps 301 are formed to extend along the first preset direction X and are spaced apart in the second preset direction Y, at least a part of the connection line S1 can be formed to extend along the second preset direction Y, and at least two connection lines S1 can be spaced apart in the first preset direction X, so as to facilitate the electrical connection of the sub-electrodes 811 in the same touch control unit 810 through the connection line S1. Among them, the number of the connection lines S1 can be multiple, and the sub-electrodes 811 in the same touch control unit 810 can be electrically connected through multiple connection lines S1 to reduce the connection resistance between the sub-electrodes 811 in the same touch control unit 810.

[0145] Optionally, the material of the connection line S1 can include a metal material. For example, the material of the connection line S1 can include copper, so that the connection line S1 can have a relatively small resistance.

[0146] Optionally, the sub-electrodes 811 in the same touch control unit 810 are formed to extend in the same direction, so that intersections are not easily generated between the sub-electrodes 811 in the touch control unit 810, so that the isolation structure 300 is not easily affected by the interference of the adjacent sub-electrodes 811 in the touch control unit 810, and it is convenient for the isolation structure 300 to extend from the display area A1 to the border area A2.

[0147] Optionally, the sub-electrodes 811 in at least part of the two adjacent touch control units 810 in the first preset direction X extend in the same direction, and / or the sub-electrodes 811 in at least part of the two adjacent touch control units 810 in the second preset direction Y extend in the same direction, so that the isolation structure 300 between the adjacent sub-electrodes 811 in a certain touch control unit 810 is not easily interfered with the sub-electrodes 811 of another touch control unit 810, and it is further convenient for the isolation structure 300 to extend from the display area A1 to the border area A2.

[0148] In some embodiments of the present application, there are various ways to set the position of the connection line S1. In some alternative embodiments, the connection line S1 can be disposed on the substrate 100.

[0149] Figure 7 It is a partial cross-sectional schematic diagram of a display panel 10 according to another embodiment of the present application.

[0150] As Figure 7As shown, in some alternative embodiments, the substrate 100 may include a driving circuit 120. Optionally, the substrate 100 may include a substrate 110, and the driving circuit 120 may be disposed on one side of the substrate 110.

[0151] Optionally, the number of driving circuits 120 is at least two, and each driving circuit 120 may respectively provide current to the second electrodes 210 in different isolation openings 300a to drive the light-emitting units 510 to emit light.

[0152] Optionally, the connection line S1 may be disposed on the side of the driving circuit 120 facing away from the touch electrode 800 to improve the layout convenience of the connection line S1, such that the connection line S1 is not easily interfered with by the components of the driving circuit 120.

[0153] Exemplarily, the driving circuit 120 may include a transistor 121. The transistor 121 may include a gate 121a and an active layer 121c located on the side of the gate 121a facing away from the touch electrode 800. The connection line S1 may be located on the side of the active layer 121c facing away from the touch electrode 800 to reduce the influence of the connection line S1 on the layout of the transistor 121. Optionally, the transistor 121 may further include source / drain electrodes 121b located on the side of the gate 121a facing away from the active layer 121c and connected to the active layer 121c. The source / drain electrodes 121b may be connected to the second electrode 210 to provide current to the second electrode 210.

[0154] Optionally, the driving circuit 120 may further include a storage capacitor 122 and driving signal lines for connecting various components, etc. Among them, the storage capacitor 122 may include a first electrode plate 122a and a second electrode plate 122b.

[0155] As an example, the first electrode plate 122a may be disposed on the same layer as the gate 121a, and the second electrode plate 122b may be located in the film layer between the source / drain electrodes 121b and the gate 121a.

[0156] Optionally, the substrate 100 further includes a bottom shield metal layer 130 (Bottom Shield Metal, BSM) located on the side of the active layer 121c facing away from the touch electrode 800. The bottom shield metal layer 130 can be used to reduce the influence of the charges in the substrate 110 on the active layer 121c of the transistor 121.

[0157] Optionally, the connection line S1 may be disposed on the same layer as the bottom shield metal layer 130, such that the connection line S1 and the bottom shield metal layer 130 can be fabricated in the same manufacturing process to improve the manufacturing efficiency of the display panel 10, and such that the connection line S1 is not easily coupled with the surrounding components to generate a coupling capacitor.

[0158] Figure 8It is a partial structural schematic diagram of a substrate 100 according to an embodiment of the present application. The dashed area in the figure represents the layout area of the driving circuit 120.

[0159] As Figure 8 shown, in some alternative embodiments, at least two driving circuits 120 are arranged at intervals, and the substrate 100 is provided with a communication hole 100a. The communication hole 100a is located between adjacent driving circuits 120, and the sub-electrode 811 is connected to the via of the connection line S1 through the communication hole 100a.

[0160] Optionally, the interval between the driving circuits 120 can be set corresponding to the accommodation gap 301. For example, the interval between the driving circuits 120 can be arranged below the accommodation gap 301, so that the communication hole 100a can communicate with the accommodation gap 301, facilitating the connection between the sub-electrode 811 and the via of the connection line S1 through the communication hole 100a.

[0161] Optionally, the distance between adjacent driving circuits 120 is greater than or equal to one-fourth and less than or equal to one-third of the size of the isolation opening 300a in the first preset direction X, and / or the distance between adjacent driving circuits 120 is greater than or equal to one-fourth and less than or equal to one-third of the size of the isolation opening 300a in the second preset direction Y, facilitating the layout of the communication hole 100a.

[0162] In some embodiments, the sub-electrode 811 can be directly connected to the connection line S1 through the via of the communication hole 100a.

[0163] Figure 9 It is a structural schematic diagram of a touch electrode 800, a connection line S1, and a conductive structure 400 according to an embodiment of the present application. Figure 10 It is a partial cross-sectional schematic diagram of a display panel 10 according to another embodiment of the present application. Figure 11 It is a partial cross-sectional schematic diagram of a display panel 10 according to still another embodiment of the present application.

[0164] As Figures 9 to 11 shown, in some other embodiments, the sub-electrode 811 includes at least two sub-segments 811a. The display panel 10 further includes a conductive structure 400 located between adjacent sub-segments 811a. Adjacent sub-segments 811a are electrically connected through the conductive structure 400, and the sub-segment 811a is electrically connected to the connection line S1 through the conductive structure 400, so that the thickness setting and material selection of the sub-electrode 811 can be independent of the influence of the communication hole 100a, facilitating the preparation of the sub-electrode 811.

[0165] Optionally, part of the conductive structure 400 can be located in the communication hole 100a and directly connected to the connection line S1.

[0166] Optionally, the sub-segments 811a may be spaced apart in the extension direction of the sub-electrode 811. For example, the sub-segments 811a may be spaced apart in the first preset direction X so as to form a strip-shaped sub-electrode 811 located in the accommodating gap 301, thereby facilitating the spacing between the sub-electrode 811 and the isolation structure 300.

[0167] Optionally, the number of the conductive structures 400 is at least two, and at least two conductive structures 400 are spaced apart in the extension direction of the sub-electrode 811. For example, the conductive structures 400 can be spaced apart in the first preset direction X to connect multiple sub-segments 811a spaced apart in the first direction, and can better reduce the connection resistance between the sub-electrode 811 and the connecting line S1, thereby better improving the touch reliability of the display panel 10.

[0168] In some embodiments of the present application, the shape of the conductive structure 400 may be the same as or similar to that of the isolation structure 300, so that the conductive structure 400 may be prepared using the same process as the isolation structure 300. For example, the conductive structure 400 includes a first conductive portion 410 and a second conductive portion 420 located on a side of the first conductive portion 410 facing away from the substrate 100, and the orthographic projection of the first conductive portion 410 on the substrate 100 is located within the orthographic projection of the second conductive portion 420 on the substrate 100.

[0169] Optionally, part of the second conductive portion 420 may be located in the connecting hole 100 a and directly connected to the connecting line S1 .

[0170] Optionally, the first conductive part 410 and the first isolation part 310 are provided in the same layer and with the same material, and / or the second conductive part 420 and the second isolation part 320 are provided in the same layer and with the same material, so that the conductive structure 400 can be prepared in the same preparation step as the isolation structure 300 to improve the preparation efficiency of the display panel 10.

[0171] Optionally, the conductive structure 400 may be directly disposed on the substrate 100 to reduce the thickness of the display panel 10. The conductive structure 400 may be disposed on the pixel defining portion 11a. For ease of description, the following embodiments are described by taking the conductive structure 400 disposed on the pixel defining portion 11a as an example.

[0172] Optionally, the touch electrode 800 may be directly disposed on the substrate 100 , or the touch electrode 800 may be disposed on the pixel defining portion 11 a . For ease of description, the following embodiments are described by taking the touch electrode 800 being disposed on the pixel defining portion 11 a as an example.

[0173] In some alternative embodiments, the display panel 10 further includes redundant material 600 at least partially located on the side of the touch control electrode 800 facing the substrate 100, and the redundant material 600 is provided with the same layer and the same material as at least part of the light-emitting units 510.

[0174] Optionally, the first electrode 710 is provided with the same layer and the same material as the touch control electrode 800.

[0175] In these alternative embodiments, when preparing the light-emitting layer 500, the material of the light-emitting layer 500 can be deposited over the entire surface, so that under the shielding and partitioning effect of the isolation structure 300, the light-emitting units 510 located within the isolation openings 300a can be formed and the material of the light-emitting layer 500 remaining in the accommodation gaps 301 can be obtained. When the material of the light-emitting layer 500 remaining in the accommodation gaps 301 is not removed, the material of the light-emitting layer 500 located in the accommodation gaps 301 can form the redundant material 600. When preparing the first electrode layer 700, the material of the first electrode layer 700 can also be deposited over the entire surface, so that under the shielding and partitioning effect of the isolation structure 300, the first electrode 710 located within the isolation openings 300a can be formed and part of the material of the first electrode layer 700 can remain in the accommodation gaps 301, such that the part of the material of the first electrode layer 700 remaining in the accommodation gaps 301 can be patterned to form the touch control electrode 800. For example, the part of the material of the first electrode layer 700 remaining in the accommodation gaps 301 can be lithographically processed so that this part of the material can be spaced apart from the isolation structure 300 to form the touch control electrode 800, thereby being able to better improve the preparation efficiency of the display panel 10.

[0176] In these alternative embodiments, the redundant material 600 can be provided with the same layer and the same material as one of the first light-emitting unit 510a, the second light-emitting unit 510b, and the third light-emitting unit 510c. Among them, the setting of the redundant material 600 can be performed according to the preparation sequence of the first light-emitting unit 510a, the second light-emitting unit 510b, and the third light-emitting unit 510c.

[0177] For example, the first light-emitting unit 510a, the second light-emitting unit 510b, and the third light-emitting unit 510c can be separately prepared. The redundant material 600 can be made of the same material as the last light-emitting unit 510 among the three. Optionally, the first light-emitting unit 510a, the second light-emitting unit 510b, and the third light-emitting unit 510c can be prepared in sequence. The redundant material 600 can be arranged on the same layer and made of the same material as the third light-emitting unit 510c. That is, when the first light-emitting unit 510a and the second light-emitting unit 510b are prepared, the materials of the first light-emitting unit 510a and the second light-emitting unit 510b that fall into the accommodation gap 301 can be removed, and only the materials of the third light-emitting unit 510c that fall into the accommodation gap 301 during the preparation of the third light-emitting unit 510c can be retained to form the redundant material 600.

[0178] Figure 12 It is a schematic diagram of the connection between a touch signal line S2 and a touch detection circuit 900 according to an embodiment of the present application.

[0179] In some alternative embodiments, such as Figure 12 shown, the display panel 10 further includes a touch signal line S2 and a touch detection circuit 900. The sub-electrodes 811 of the touch unit 810 are connected to the touch detection circuit 900 through the touch signal line S2. The touch detection circuit 900 is used to detect the capacitance between the sub-electrode 811 and the ground when the target object contacts the display panel 10.

[0180] In some embodiments, the number of touch signal lines S2 can be the same as the number of touch units 810, that is, the touch signal of one touch unit 810 can be led out by only one touch signal line S2. In some other embodiments, the number of touch signal lines S2 can be more than the number of touch units 810, that is, the touch signal of one touch unit 810 can be led out by multiple touch signal lines S2, and the touch signal lines S2 connected to the same touch unit 810 can be connected in parallel with each other, so as to reduce the resistance during the transmission of the touch signal.

[0181] In some embodiments of the present application, there are various ways to set the film layer position of the touch signal line S2.

[0182] In some alternative embodiments, such as Figure 12 shown, at least part of the touch signal line S2 can be arranged on the same layer and made of the same material as the connection line S1, so that the touch signal line S2 can be prepared in the same manufacturing process as the connection line S1, thereby improving the manufacturing efficiency of the display panel 10. Moreover, when the connection line S1, the touch signal line S2, and the bottom shielding metal layer 130 are all arranged on the same layer, it is convenient to arrange the touch signal line S2 and reduce the interference to the arrangement of other devices in the display panel 10 during the arrangement of the touch signal line S2.

[0183] Optionally, the touch signal line S2 can be connected to the connection line S1, so that the sub-electrode 811 of the touch unit 810 can be electrically connected to the touch signal line S2 through the connection line S1.

[0184] Optionally, at least a part of the orthographic projection of the touch signal line S2 on the substrate 100 can overlap with the orthographic projection of the sub-electrode 811 on the substrate 100, so that the arrangement shape of the touch signal line S2 can be similar to the arrangement shape of the sub-electrode 811, facilitating the connection between the touch signal line S2 and the connection line S1.

[0185] Optionally, at least a part of the touch signal line S2 can be formed by extending along the extension direction of the accommodation gap 301, and / or at least two touch signal lines S2 are spaced apart in the spacing arrangement direction of the accommodation gap 301.

[0186] For example, when at least two accommodation gaps 301 are formed by extending along the first preset direction X and are spaced apart in the second preset direction Y, at least two touch signal lines S2 can be formed by extending along the first preset direction X and are spaced apart in the second preset direction Y, and / or when at least two accommodation gaps 301 are formed by extending along the second preset direction Y and are spaced apart in the first preset direction X, at least two touch signal lines S2 can be formed by extending along the second preset direction Y and are spaced apart in the first preset direction X, so that the touch signal line S2 can have a larger arrangement area, facilitating the reduction of the resistance during touch signal transmission.

[0187] Figure 13 It is a schematic connection diagram of a touch unit 810 and a touch detection circuit 900 according to an embodiment of the present application.

[0188] In some other alternative embodiments, as Figure 13 shown, at least a part of the touch signal line S2 is provided on the same layer and made of the same material as the touch electrode 800, so that the touch signal line S2 can be prepared in the same preparation step as the touch electrode 800 to improve the preparation efficiency of the display panel 10. For example, at least a part of the touch signal line S2 can be disposed in the accommodation gap 301, and the touch signal line S2 is connected to at least a part of the sub-electrode 811. Optionally, there may be some redundant material 600 between the touch signal line S2 and the substrate 100.

[0189] In some embodiments, as Figure 12 and Figure 13 shown, the touch signal line S2 can directly extend from the display area A1 to the border area A2 to be connected to the touch detection circuit 900, so that the arrangement area of the touch signal line S2 in the border area A2 can be better reduced, so as to better reduce the area of the border area A2 of the display panel 10, thereby better improving the screen-to-body ratio of the display panel 10.

[0190] Figure 14It is a schematic diagram showing the connection between a touch signal line S2 and a touch detection circuit 900 according to another embodiment of the present application. Figure 15 It is a schematic diagram showing the connection between a touch unit 810 and a touch detection circuit 900 according to another embodiment of the present application.

[0191] In some other embodiments, as Figure 14 shown, when at least part of the touch signal lines S2 are arranged on the same layer and made of the same material as the connection lines S1, a part of the touch signal lines S2 can be arranged in the border area A2, and the other part of the touch signal lines S2 located in the display area A1 can be electrically connected to the touch signal lines S2 in the border area A2 through the connection lines S1. By arranging part of the touch signal lines S2 in the border area A2 for connection with the touch detection circuit 900, a sufficient number of touch signal lines S2 can be arranged in the display area A1, so as to further reduce the resistance during the transmission of touch signals. Or as Figure 15 shown, when at least part of the touch signal lines S2 are arranged on the same layer and made of the same material as the touch electrodes 800, at least part of the touch signal lines S2 can be arranged in the border area A2, and the sub-electrodes 811 located in the display area A1 can be electrically connected to the touch signal lines S2 in the border area A2 through the connection lines S1, so that a sufficient number of sub-electrodes 811 and sub-electrodes 811 with a larger area can be arranged in the accommodation gap 301 in the display area A1, thereby better improving the touch ability of the display panel 10.

[0192] Optionally, the connection line S1 connected to the touch signal line S2 can be at least partially located between two adjacent touch units 810, which is convenient for the arrangement of the connection line S1 and can reduce the crosstalk effect between the signal in the connection line S1 and the signals in the surrounding touch units 810 not connected to the connection line S1.

[0193] Optionally, when the touch signal line S2 in the border area A2 is connected to a certain connection line S1, the sub-electrode 811 connected to this connection line S1 can be slightly longer than other sub-electrodes 811, or the touch signal line S2 in the display area A1 connected to this connection line S1 can be slightly longer than other touch signal lines S2 in the display area A1, so as to at least partially arrange the connection line S1 connected to the touch signal line S2 between two adjacent touch units 810.

[0194] Optionally, the touch detection circuit 900 can include a signal generation module and a capacitance detection module. The signal generation module is used to provide a square wave signal to the sub-electrode 811, and the capacitance detection module is used to receive the square wave signal transmitted from the sub-electrode 811.

[0195] In these alternative embodiments, the touch detection circuit 900 can obtain the capacitance changes at the sub-electrodes 811 in each touch unit 810 through the touch signal line S2. For example, when a finger touches a certain touch unit 810 of the display panel 10 as a conductor, the capacitance on the sub-electrode 811 of the touch unit 810 increases, enabling the touch detection circuit 900 to identify and locate the finger touch position by detecting the capacitance change of the sub-electrode 811 of the touch unit 810, thereby enabling the display panel 10 to achieve the touch function.

[0210] Optionally, when sequentially removing the materials of the first electrode 710 outside the first opening 300b and the materials of the first light-emitting unit 510a, a protective material may be disposed above the material of the first electrode 710 in the first opening 300b. For example, the protective material may be a photoresist, so that the materials of the first electrode 710 and the first light-emitting unit 510a in the first opening 300b are not easily etched and removed under the protection of the protective material.

[0211] Step S022: As Figure 19 shown, prepare a second light-emitting unit 510b and a part of the first electrode 710 disposed on the side of the second light-emitting unit 510b away from the substrate 100 in the second opening 300c.

[0215] Optionally, when sequentially removing the conductive material layer and the second light-emitting material layer outside the second opening 300c, a protective material may be disposed above the material of the first electrode 710 in the second opening 300c. For example, the protective material may be a photoresist, so that the materials of the first electrode 710 and the second light-emitting unit 510b in the second opening 300c are not easily etched and removed under the protection of the protective material.

[0216] Step S023: As Figure 20 shown, prepare a third light-emitting unit 510c and a part of the first electrode 710 disposed on the side of the third light-emitting unit 510c away from the substrate 100 in the third opening 300d, and prepare a touch electrode 800 in the accommodation gap 301.

[0220] Optionally, when sequentially removing the conductive material layer and the third light-emitting material layer located outside the third opening 300d and the accommodation gap 301, a protective material may be disposed above the materials of the first electrode 710 in the third opening 300d and the accommodation gap 301. For example, the protective material may be a photoresist, so that the materials of the first electrode 710 and the third light-emitting unit 510c in the third opening 300d and the accommodation gap 301 are not easily etched and removed under the protection of the protective material. Among them, the materials of the third light-emitting unit 510c retained in the third opening 300d and the first electrode 710 can be respectively used to form the third light-emitting unit 510c and the first electrode 710 disposed on the side of the third light-emitting unit 510c away from the substrate 100, while the materials of the third light-emitting unit 510c and the first electrode 710 retained in the accommodation gap 301 can be respectively used to form the redundant material 600 and the touch electrode 800 disposed on the side of the redundant material 600 away from the substrate 100.

[0221] Optionally, the protective material disposed in the accommodation gap 301 can be disposed at an interval from the isolation structure 300, so that the edge portion of the material of the first electrode 710 in the accommodation gap 301 facing the isolation structure 300 can be exposed from the interval between the protective material and the isolation structure 300, so that when removing a part of the material of the first electrode 710, for example, when etching a part of the material of the first electrode 710, the material of the first electrode 710 exposed from the interval between the protective material and the isolation structure 300 can be removed, so that the formed touch electrode 800 can be disposed at an interval from the isolation structure 300, thereby realizing insulation between the touch electrode 800 and the isolation structure 300, and making the signal in the first electrode 710 not easily generate crosstalk with the signal in the touch electrode 800 through the isolation structure 300.

[0222] In these alternative embodiments, by retaining the material of the third light-emitting unit 510c and the material of the first electrode 710 within the accommodation gap 301, the material of the first electrode 710 retained within the accommodation gap 301 can be used to form the touch electrode 800. Such that during the preparation process of the display panel 10, the touch electrode 800 can be prepared in the same preparation process as the first electrode 710 of the display panel 10, which can preferably reduce the preparation cost of the display panel 10 and can preferably improve the preparation efficiency of the display panel 10.

And, compared with the display panel 10 in the previous embodiment where the accommodation gap 301 is formed between adjacent isolation structures 300, by opening the accommodation gap 301 in the isolation structure 300, the layout area of the isolation structure 300 can be increased, thereby preferably improving the sub-pixel arrangement density of the display panel 10.

[0227] In some embodiments of the present application, during the preparation process of the display panel 10, under the shielding and partitioning effect of the isolation structure 300 on the material of the light-emitting unit 510, the light-emitting units 510 having different light-emitting colors in the display panel 10 and their corresponding first electrodes 710 can be prepared relatively independently.

[0234] Optionally, when sequentially removing the material of the first electrode 710 and the material of the first light-emitting unit 510a located outside the first opening 300b, a protective material can be provided above the material of the first electrode 710 within the first opening 300b. For example, the protective material can be a photoresist, such that the material of the first electrode 710 and the material of the first light-emitting unit 510a within the first opening 300b are not easily etched and removed under the protection of the protective material.

[0235] Step S022: As Figure 19 shown, prepare the second light-emitting unit 510b and a part of the first electrode 710 disposed on the side of the second light-emitting unit 510b facing away from the substrate 100 within the second opening 300c.

[0236] Optionally, step S022 may include:

[0244] Optionally, when successively removing the conductive material layer and the third light-emitting material layer located outside the third opening 300d and the accommodation gap 301, a protective material may be disposed above the material of the first electrode 710 in the third opening 300d and the accommodation gap 301. For example, the protective material may be a photoresist, so that the material of the first electrode 710 and the material of the third light-emitting unit 510c in the third opening 300d and the accommodation gap 301 are not easily etched and removed under the protection of the protective material. Among them, the material of the third light-emitting unit 510c remaining in the third opening 300d and the material of the first electrode 710 may be respectively used to form the third light-emitting unit 510c and the first electrode 710 on the side of the third light-emitting unit 510c facing away from the substrate 100, while the material of the third light-emitting unit 510c remaining in the accommodation gap 301 and the material of the first electrode 710 may be respectively used to form the redundant material 600 and the touch electrode 800 on the side of the redundant material 600 facing away from the substrate 100.

[0245] Optionally, the protective material disposed in the accommodation gap 301 may be spaced apart from the isolation structure 300, so that the edge portion of the material of the first electrode 710 in the accommodation gap 301 facing the isolation structure 300 can be exposed from the gap between the protective material and the isolation structure 300, so that when removing a part of the material of the first electrode 710, for example, when etching a part of the material of the first electrode 710, the material of the first electrode 710 exposed from the gap between the protective material and the isolation structure 300 can be removed, so that the formed touch electrode 800 can be spaced apart from the isolation structure 300, thereby realizing insulation between the touch electrode 800 and the isolation structure 300, and making the signal in the first electrode 710 not easily generate crosstalk with the signal in the touch electrode 800 through the isolation structure 300.
