[0104] like Figures 1 to 4 As shown, an embodiment of the first aspect of the present application provides a display panel 10, including: a substrate 100; an isolation structure 300, which is arranged on one side of the substrate 100, and the isolation structure 300 encloses an isolation opening 300a and a receiving opening 300b; a light-emitting device 400, at least part of the structure of the light-emitting device 400 is located in the isolation opening 300a; a touch electrode 500, which is arranged in the receiving opening and insulated from the isolation structure 300; a shielding structure L2, which is located on the side of the touch electrode 500 facing the substrate 100; a touch trace L1, which is connected to the touch electrode 500 and is arranged on the same layer as the shielding structure L2.

[0105] 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 500, a shielding structure L2, and a touch trace L1. The isolation structure 300 is disposed on one side of the substrate 100, and the isolation structure 300 encloses an isolation opening 300a. 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.

[0106] Related solutions of the isolation structure 300 (also called partition structure, etc.) are disclosed in patents (applications) CN118251982A, 202410864269.8, PCT / CN2024 / 098407, PCT / CN2024 / 102783, PCT / CN2024 / 098217, PCT / CN2024 / 099419, PCT / CN2024 / 099072, CN117979 755A, CN117998900A, CN117062489A, CN117580403A, CN116583155A, CN116669477A, ​​CN117396039A, CN116669480A, CN116600606A, CN117500332A, etc., the contents of which are incorporated into this application by reference for reference.

[0107] The isolation structure 300 also encloses a receiving opening 300b, and the touch electrode 500 is arranged in the receiving opening and insulated from the isolation structure 300, so that there is no need to set an additional layer structure above the isolation structure 300 to arrange the touch electrode 500, so that the display panel 10 can have a smaller thickness.

[0108] Optionally, the isolation structure 300 may be in a grid shape, and the hollowed-out area in the grid-shaped isolation structure 300 may form isolation openings 300 a and receiving openings 300 b to facilitate the isolation structure 300 to divide the sub-pixels of the display panel 10 and to facilitate the reception of the touch electrodes 500 .

[0109] Optionally, there are various ways to set the insulation between the touch electrode 500 and the isolation structure 300.

[0110] The shielding structure L2 is located on the side of the touch electrode 500 facing the substrate 100. The shielding structure L2 can be used to limit the interference between the signal in the touch electrode 500 and the signal in the substrate 100, which can improve the working stability of the display panel 10. The touch line L1 is connected to the touch electrode 500. The touch line L1 can be used to transmit the touch signal to realize the touch function of the touch electrode 500.

[0138] In some embodiments of the present application, the touch line L1 and the shielding structure L2 are disposed in the same layer, which may mean that the touch line L1 and the shielding structure L2 are located between the same two film layer structures. There are many ways to position the shielding structure L2 and the touch line L1.

[0139] like Figure 3 As shown, in some optional embodiments, the shielding structure L2 may be disposed on the same layer as the first electrode 410 .

[0140] like Figure 4 As shown, since the touch line L1 and the shielding structure L2 are disposed on the same layer, both the shielding structure L2 and the touch line L1 can be disposed on the same layer as the first electrode 410 .

[0141] Optionally, the shielding structure L2 may be located between the pixel defining portion 210 and the substrate 100.

[0145] Optionally, the shielding structure L2 may be located between adjacent first electrodes 410. For example, the shielding structure L2 may be located between adjacent first electrodes 410 and spaced apart from the first electrodes 410, so that the setting of the shielding structure L2 is not likely to interfere with the arrangement of the first electrodes 410, thereby better improving the structural stability and working stability of the display panel 10.

[0147] In these optional embodiments, by setting the shielding structure L2 and the touch line L1 in the same layer as the first electrode 410, the position in the film layer where the first electrode 410 is located in the display panel 10 (for example, between the pixel defining portion 210 and the planarization layer 160) that is not used to arrange the first electrode 410 can be better used to arrange the shielding structure L2 and the touch line L1, so that the touch line L1 can transmit the touch signal in the film layer where the first electrode 410 is located, and the shielding structure L2 can better limit the interference between the signal in the touch electrode 500 and the signal in the substrate 100 in the film layer where the first electrode 410 is located, which can better improve the working stability of the display panel 10 and the structural compactness of the display panel 10. In addition, the touch line L1 and the shielding structure L2 can be prepared in the same preparation step using the same or similar preparation equipment, thereby better improving the preparation efficiency of the display panel 10.

[0148] Figure 5 is a partial cross-sectional schematic diagram of a display panel 10 according to another embodiment of the present application. Figure 6 FIG. 1 is a partial cross-sectional schematic diagram of a display panel 10 according to another embodiment of the present application.

[0149] like Figure 5 and Figure 6 As shown, in some optional embodiments, the shielding structure L2 may be disposed within the substrate 100 .

[0150] Since the touch line L1 and the shielding structure L2 are disposed on the same layer, both the shielding structure L2 and the touch line L1 can be disposed in the substrate 100 .

[0151] Optionally, the shielding structure L2 and the touch line L1 may be disposed between any two film layers in the substrate 100 .

[0152] Optionally, the shielding structure L2 may be disposed between the planarization layer 160 and the substrate 110. Exemplarily, the shielding structure L2 and the touch-sensing trace L1 may be disposed between the planarization layer 160 and the substrate 110.

[0153] Optionally, the shielding structure L2 may be disposed between the driving circuit 150 and the planarization layer 160. Exemplarily, the shielding structure L2 and the touch line L1 may be disposed between the driving circuit 150 and the planarization layer 160, for example, the shielding structure L2 and the touch line L1 may be disposed between the third insulating layer 140 and the planarization layer 160.

[0154] In this optional embodiment, the shielding structure L2 and the touch line L1 can be arranged between the driving circuit 150 and the planarization layer 160, so that the arrangement of the shielding structure L2 and the touch line L1 is not easy to interfere with the arrangement of various devices in the driving circuit 150, and the shielding structure L2 can better limit the interference between the signal in the touch electrode 500 and the signal in the driving circuit 150 between the driving circuit 150 and the planarization layer 160, which can improve the working stability of the display panel 10 and the structural compactness of the display panel 10.

[0155] Optionally, when the shielding structure L2 and the touch line L1 are arranged in the substrate 100, the material of the shielding structure L2 and the touch line L1 may include indium tin oxide, and / or, the shielding structure L2 and the touch line L1 may be the same as the material of other devices in the same layer in the substrate 100, which is not specifically limited in the present application.

[0156] In some optional embodiments, the shielding structure L2 can be electrically connected to the fixed signal terminal in the display panel 10, so that the fixed signal terminal can provide a relatively stable voltage to the shielding structure L2, thereby better improving the shielding and shielding effect of the shielding structure L2 on the signal in the touch electrode 500 and the signal in the substrate 100, making it less likely for the signal in the touch electrode 500 and the signal in the substrate 100 to interfere with each other.

[0157] Optionally, the fixed signal terminal may include a DC voltage signal terminal.

[0158] Optionally, the DC voltage signal terminal includes at least one of a touch ground signal line, an initialization signal line, a negative power supply voltage signal line, and a positive power supply voltage signal line.

[0159] like Figure 3 and Figure 4 As shown, optionally, when the fixed signal terminal is disposed in the substrate 100 , the shielding structure L2 may be connected to the fixed signal terminal via.

[0160] Figure 7 FIG. 1 is a partial cross-sectional schematic diagram of a display panel 10 according to another embodiment of the present application.

[0161] Optionally, when the shielding structure L2 needs to be electrically connected to the negative power supply voltage signal line, the shielding structure L2 can be electrically connected to the negative power supply voltage signal line through the isolation structure 300, so that the shielding structure L2 can receive a relatively stable negative power supply voltage signal through the isolation structure 300. Exemplarily, the shielding structure L2 can be connected to the isolation structure 300 via a via, so that the shielding structure L2 can be electrically connected to the negative power supply voltage signal line through the isolation structure 300.

[0162] In some optional embodiments, the orthographic projection of the shielding structure L2 on the substrate 100 and the orthographic projection of the touch electrode 500 on the substrate 100 are at least partially overlapped, so that the shielding structure L2 can better limit the interference between the signal in the touch electrode 500 and the signal in the substrate 100.

[0163] Optionally, the orthographic projection of the shielding structure L2 on the substrate 100 and the orthographic projection of the touch electrode 500 on the substrate 100 may be arranged to only partially overlap, so that the arrangement of the shielding structure L2 is not likely to affect the arrangement of other devices. For example, in order to reduce the impact of the shielding structure L2 on the arrangement of other device structures in the substrate 100, the extension direction of the shielding structure L2 may intersect with the extension direction of the touch electrode 500, and the orthographic projection of the shielding structure L2 on the substrate 100 and the orthographic projection of the touch electrode 500 on the substrate 100 only partially overlap.

[0164] In some optional embodiments, the orthographic projection of the touch line L1 on the substrate 100 and the orthographic projection of the touch electrode 500 on the substrate 100 are at least partially overlapped, which can facilitate the connection between the touch line L1 and the touch electrode 500. For example, the orthographic projection of the touch line L1 on the substrate 100 and the orthographic projection of the touch electrode 500 on the substrate 100 are at least partially overlapped, which can facilitate the via-hole connection between the touch line L1 and the touch electrode 500.

[0165] Optionally, the orthographic projection of the touch line L1 on the substrate 100 and the orthographic projection of the touch electrode 500 on the substrate 100 may be arranged to only partially overlap, so that the arrangement of the touch line L1 is not likely to affect the arrangement of other devices. For example, in order to reduce the impact of the touch line L1 on the arrangement of other device structures in the substrate 100 and to facilitate the connection of the touch line L1 with multiple touch electrodes 500, the extension direction of the touch line L1 may intersect with the extension direction of the touch electrode 500, and the orthographic projection of the shielding structure L2 on the substrate 100 and the orthographic projection of the touch electrode 500 on the substrate 100 only partially overlap.

[0166] Figure 8 1 is a schematic diagram of the structure of a touch electrode 500, a shielding structure L2, a touch trace L1, and a touch chip 20 according to an embodiment of the present application. When there is a box at the intersection of the touch electrode 500 and the touch trace L1 in the figure, it can indicate that the touch electrode 500 and the touch trace L1 are connected at the box. When there is no box at the intersection of the touch electrode 500 and the touch trace L1 in the figure, it can indicate that the touch electrode 500 and the touch trace L1 at the intersection are not connected.

[0167] like Figure 8 As shown, in some optional embodiments, the display panel 10 may have multiple touch areas TA, the touch electrode 500 may include multiple sub-electrodes 501, and the sub-electrodes 501 located in the same touch area TA may be electrically connected through the touch wiring L1.

[0168] Optionally, the sub-electrodes 501 located in different touch control areas TA are insulated.

[0169] In these optional embodiments, the sub-electrodes 501 located in the same touch area TA can be electrically connected through the touch line L1, so that in the display panel 10, the touch area TA can be used as a unit to participate in the touch operation of the display panel 10, so as to facilitate the related control of the touch electrode 500 in the display panel 10.

[0170] Optionally, each sub-electrode 501 may be located in a different receiving opening 300 b , so that there is no need to provide an oversized receiving opening 300 b , and it is convenient to arrange larger and more densely packed isolation openings 300 a in the display panel 10 .

[0171] Optionally, since the receiving opening 300b is used to receive the sub-electrode 501, the extension direction and arrangement form of the receiving opening 300b in the embodiment of the present application can be set with reference to the extension direction and arrangement form of the sub-electrode 501 in each embodiment of the present application. For example, the extension direction and arrangement form of the receiving opening 300b can be the same as or similar to the extension direction and arrangement form of the sub-electrode 501 in each embodiment of the present application, and the present application will not elaborate on it.

[0172] Optionally, the sub-electrodes 501 in the same touch area TA may be electrically connected via multiple or a single touch line L1. For ease of description, the following embodiments are described by taking the sub-electrodes 501 in the same touch area TA as an example of being electrically connected via a single touch line L1.

[0173] Optionally, the touch line L1 can be used to connect to a touch chip 20 (Touch Key Integrated Circuit, Touch Key IC), so that the touch electrode 500 can be electrically connected to the touch chip 20 through the touch line L1, and the touch chip 20 can detect the capacitance change on the touch electrode 500 located at a corresponding position in the display panel 10 through the touch line L1 to perform identification and positioning, thereby realizing touch display of the display panel 10.

[0174] In some embodiments of the present application, when the sub-electrodes 501 located in the same touch area TA are electrically connected through a single touch line L1, the number of touch lines L1 arranged in the display panel 10 can be reduced, thereby facilitating the arrangement of the shielding structure L2 arranged on the same layer as the touch line L1, so that a shielding structure L2 with a larger area and a larger size can be arranged in the display panel 10, thereby better improving the shielding effect of the shielding structure L2 and improving the working stability of the display panel 10.

[0175] In some embodiments of the present application, the display panel 10 may be a display panel 10 that implements touch positioning based on a self-capacitive touch architecture, that is, the touch electrode 500 may be specifically used as an electrode for excitation and detection. When a finger touches the display panel 10 as a conductor, the capacitance of the sub-electrode 501 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.

[0176] For example, when a finger as a conductor touches the display panel 10, the sub-electrode 501 in the touch area TA at the corresponding position will be affected by the finger to derive a portion of the charge, thereby causing a capacitance change. Wherein, Cp is the parasitic capacitance between the sub-electrode 501 and the ground, and Cf is the induction capacitance between the induction electrode and the ground generated by the human body when the finger touches. When the finger as a conductor touches the display panel 10, it is equivalent to Cp and Cf in parallel, so that the parasitic capacitance = Cp + Cf, that is, the parasitic capacitance increases, so that the recognition and positioning can be performed through the capacitance change, thereby realizing the touch display of the display panel 10.

[0177] When the touch electrode 500 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-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 electrode 500 is required 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.

[0178] In some embodiments of the present application, in order to realize the touch function of the display panel 10 , there are various arrangements of the touch area TA and the sub-electrodes 501 .

[0179] In some optional embodiments, the touch areas TA may be arranged in an array in the first direction X and the second direction Y. For example, a plurality of columns of touch areas TA may be arranged in the first direction X, a plurality of rows of touch areas TA may be arranged in the second direction Y, the touch areas TA in the same column may be arranged at intervals in the second direction Y, and the touch areas TA in the same row may be arranged at intervals in the first direction X.

[0180] Optionally, the sub-electrode 501 may extend along the first direction X, and a plurality of sub-electrodes 501 located in the same touch area TA may be spaced apart in the second direction Y. Optionally, the touch line L1 may extend along the second direction Y, so that a single touch line L1 may simultaneously connect a plurality of sub-electrodes 501 spaced apart in the second direction Y, so that the sub-electrodes 501 located in the same touch area TA may be electrically connected through the touch line L1.

[0181] Optionally, the shielding structure L2 may extend along the second direction Y, so that the extension shape of the shielding structure L2 may be similar to or identical to the extension shape of the touch line L1, so that the arrangement of the shielding structure L2 and the arrangement of the touch line L1 are not likely to interfere with each other, that is, it can facilitate the arrangement of the shielding structure L2 and the touch line L1 located on the same layer in the display panel 10, and thus it can facilitate the improvement of the structural compactness of the display panel 10. For example, the shielding structure L2 may extend along the second direction Y and be strip-shaped. Moreover, a single shielding structure L2 can be used to simultaneously participate in limiting the interference between the signals in at least two adjacent sub-electrodes 501 in the second direction Y and the signals in the substrate 100, which can better improve the shielding efficiency of the shielding structure L2, and can facilitate the arrangement of the shielding structure L2, so that a large number of shielding structures L2 do not need to be set in the display panel 10.

[0182] Optionally, the accommodating opening 300b may be at least partially located between adjacent isolation openings 300a in the second direction Y, so as to better utilize the gap between two adjacent rows of isolation openings 300a, and facilitate the extension of the accommodating opening 300b along the first direction X, so that the sub-electrode 501 in the accommodating opening 300b can have a larger extension dimension in the first direction X.

[0183] In some optional embodiments, the sub-electrode 501 may include a main body portion 501 a extending along the first direction X and an extension portion 501 b protruding from the main body portion 501 a in the second direction Y.

[0184] Optionally, the accommodating opening 300b accommodating the main body 501a is located between adjacent isolation openings 300a in the second direction Y, and the accommodating opening 300b accommodating the extension portion 501b is located between adjacent isolation openings 300a in the first direction X, so that the gap between two adjacent rows of isolation openings 300a and the gap between two adjacent columns of isolation openings 300a can be better utilized to arrange the accommodating openings 300b and the sub-electrode 501, so that the sub-electrode 501 can have a larger size.

[0185] Optionally, a single sub-electrode 501 may include a main body portion 501a and at least two extension portions 501b, and the extension portions 501b in the single sub-electrode 501 may be disposed on both sides of the main body portion 501a in the second direction Y.

[0186] In these optional embodiments, by providing the extension portion 501 b protruding from the main body portion 501 a , the arrangement area of ​​the sub-electrode 501 can be improved, thereby improving the touch capability of the display panel 10 .

[0187] In some optional embodiments, the shielding structure L2 may be spaced apart from the touch line L1 in the first direction X, and / or, there are multiple shielding structures L2 and multiple shielding structures L2 may be spaced apart in the first direction X, and / or, there are multiple touch lines L1 and multiple touch lines L1 may be spaced apart in the first direction X.

[0188] Optionally, a single touch area TA may extend through a single or multiple shielding structures L2 , and a single touch area TA may extend through a single or multiple touch traces L1 .

[0189] When a plurality of shielding structures L2 extend through a single touch area TA, the shielding structures L2 in the single touch area TA may be arranged at intervals in the first direction X, so that relatively dense shielding structures L2 are arranged in the touch area TA.

[0190] When multiple touch lines L1 extend through a single touch area TA, the touch lines L1 in the single touch area TA can be spaced apart in the first direction X, and only one touch line L1 among the multiple touch lines L1 can be connected to the sub-electrode 501 in the touch area TA, while the other touch lines L1 among the multiple touch lines L1 can be used to connect to the sub-electrodes 501 in other touch areas TA.

[0191] When a single touch area TA extends through both the touch line L1 and the shielding structure L2, the shielding structure L2 and the touch line L1 may be spaced apart in the first direction X. For example, when a single touch area TA extends through multiple touch lines L1 and multiple shielding structures L2, Figure 8 As shown, the shielding structures L2 in the touch area TA may be located on the same side of the touch line L1 in the touch area TA in the first direction X, that is, the shielding structures L2 and the touch line L1 in the touch area TA may be arranged on both sides of the first direction X, so as to facilitate the arrangement of the touch line L1 and the shielding structures L2, and to reduce the interference of the signal in the touch line L1 with the signal in the shielding structure L2; or, when a plurality of touch lines L1 and a plurality of shielding structures L2 extend through a single touch area TA at the same time, the shielding structures L2 in the touch area TA may be arranged alternately with the touch line L1 in the first direction X (not shown in the figure), that is, part of the touch line L1 may be located between two adjacent shielding structures L2, and / or part of the shielding structure L2 may be located between two adjacent touch lines L1.

[0192] For ease of description, the following embodiments are described by taking “the shielding structures L2 in a single touch area TA may all be located on the same side of the touch lines L1 in the touch area TA in the first direction X” as an example.

[0193] like Figure 8 As shown, in some optional embodiments, a columns of touch control areas TA are arranged in the first direction X, and b rows of touch control areas TA are arranged in the second direction Y, where a and b are both positive integers, a≥1, b≥2. Exemplarily, when the touch control trace L1 in the display panel 10 is connected to the touch control chip 20, the touch control chip 20 can be disposed on one side of the display panel 10 in the second direction Y.

[0194] In some optional embodiments, the number of touch lines L1 extending through the nth row of touch areas TA is less than the number of touch lines L1 extending through the n+1th row of touch areas TA, where n is a positive integer and 1≤n≤b-1.

[0195] In this optional embodiment, when the number of touch lines L1 extending through the n-th row of touch areas TA is less than the number of touch lines L1 extending through the n+1-th row of touch areas TA, it is possible to facilitate the connection between the touch lines L1 and the touch chip 20. Exemplarily, when the touch chip 20 is disposed on one side of the display panel 10 in the second direction Y, for example, when the touch chip 20 is disposed on the side of the b-th row of touch areas TA away from the first row of touch areas TA, since the touch lines L1 connected to the sub-electrodes 501 in each touch area TA need to extend toward the touch chip 20 to connect with the touch chip 20, and do not need to extend to the side away from the touch chip 20, therefore, in two adjacent rows of touch areas TA in the second direction Y, the number of touch lines L1 extending through the touch area TA in one row closer to the touch chip 20 is greater than the number of touch lines L1 extending through the touch area TA in the other row farther away from the touch chip 20. For example, the number of touch lines L1 extending through a touch area TA in the first row may be only 1, and the touch line L1 is connected to the sub-electrode 501 in the touch area TA. For example, the number of touch lines L1 extending through a touch area TA in the b-th row may be b, and only one of the b touch lines L1 is connected to the sub-electrode 501 in the touch area TA, and the remaining b-1 touch lines L1 may be touch lines L1 connected to the sub-electrodes 501 in the touch areas TA in the first row to the b-1th row.

[0196] Exemplarily, when the sub-electrodes 501 located in the same touch area TA are electrically connected through a single touch line L1, and a≥2, each touch area TA in the b-th row has b touch lines L1 extending through it, and among the b touch lines L1 extending through the touch area TA located in the m-th column of the b-th row, the i-th touch line L1 extends through the touch area TA from the i-th row of the m-th column to the b-th row, where m and i are both positive integers, 1≤m≤a, 1≤i≤b. For example, Figure 8 As shown, among the two touch lines L1 extending through the touch area TA located in the first column of the second row, the first touch line L1 can extend through the touch area TA from the first row of the first column to the second row, and the second touch line L1 can only extend through the touch area TA of the second row of the first column.

[0197] In some optional embodiments, the number of shielding structures L2 extending through the n-th row of touch control areas TA is greater than the number of touch control traces L1 extending through the n+1-th row of touch control areas TA, where n is a positive integer, 1≤n≤b-1.

[0198] In this optional embodiment, by setting the number of shielding structures L2 extending through the n-th row touch area TA to be greater than the number of touch lines L1 extending through the n+1-th row touch area TA, when the number of touch lines L1 extending through the n-th row touch area TA is less than the number of touch lines L1 extending through the n+1-th row touch area TA, a larger number of shielding structures L2 can be arranged in the touch area TA extending through a smaller number of touch lines L1, so that in the film layer where the touch lines L1 in the display panel 10 are located, the portion of the film layer position that is not used to arrange the touch lines L1 can be more fully utilized to arrange the shielding structures L2, thereby better improving the working stability of the display panel 10 while also improving the structural compactness of the display panel 10.

[0199] Exemplarily, when the sub-electrodes 501 located in the same touch area TA are electrically connected through a single touch line L1, and a≥2, each touch area TA in the first row extends through c shielding structures L2, and among the c shielding structures L2 extending through the touch area TA located in the p-th column of the first row, the j-th shielding structure L2 extends through the touch area TA from the first row of the p-th column to the j-th row, where p and j are both positive integers, 1≤p≤a, and j≥1. For example, Figure 8 As shown, among the three shielding structures L2 extending through the touch area TA located in the first column of the first row, the first shielding structure L2 may only extend through the touch area TA of the first row of the first column, and the second shielding structure L2 and the third shielding structure L2 may extend through the touch area TA from the first row of the first column to the second row.

[0200] According to some of the aforementioned embodiments, in some optional embodiments, the total number of touch lines L1 and shielding structures L2 extending through any touch area TA in the display panel 10 may be (c+1), that is, the total number of touch lines L1 and shielding structures L2 extending through each touch area TA is the same, so that the touch lines L1 and shielding structures L2 are arranged more evenly in the display panel 10. For example, when the number of touch lines L1 extending through a touch area TA in the b-th row is b, the number of shielding structures L2 extending through the touch area TA may be (c+1-b).

[0201] Fig. 9 It is a partial enlarged structural diagram of a light emitting device 400, a shielding structure L2 and a touch line L1 according to an embodiment of the present application.

[0202] In some optional embodiments, a single touch line L1 has a first projection in the thickness direction Z of the display panel 10, a single shielding structure L2 has a second projection in the thickness direction Z of the display panel 10, a single light-emitting device 400 has a third projection in the thickness direction Z of the display panel 10, and there are c columns of third projections arranged at intervals in the first direction X between two adjacent first projections, and / or, there are d columns of third projections arranged at intervals in the first direction X between two adjacent second projections, and / or, there are e columns of third projections arranged at intervals in the first direction X between adjacent first and second projections, and c, d and e are all positive integers, c≥2, d≥2, e≥2.

[0203] Optionally, c=3, and / or, d=3, and / or, e=3.

[0204] In these optional embodiments, by reasonably setting the arrangement relationship among the first projection, the second projection and the third projection, the arrangement density of the touch line L1 and the shielding structure L2 can be better arranged according to the arrangement density of the light-emitting device 400, so that the touch line L1 and the shielding structure L2 can have a more appropriate arrangement density, so that the arrangement of the touch line L1 and the shielding structure L2 is not easy to affect the arrangement of the driving circuit 150 under the light-emitting device 400, thereby better improving the structural compactness of the display panel 10.

[0205] Optionally, the light emitting device 400 includes a first type device 401 , a second type device 402 , and a third type device 403 , which emit light of different colors, so as to realize color light emitting display of the display panel 10 .

[0206] In some optional embodiments, an adjacent first-type device 401, a second-type device 402, and a third-type device 403 constitute a pixel unit, and the pixel unit has a fourth projection in the thickness direction Z of the display panel 10, and there is at least one column of fourth projections between two adjacent first projections, and / or, there is at least one column of fourth projections between two adjacent second projections, and / or, there is at least one column of fourth projections between adjacent first projections and second projections.

[0207] Optionally, the first type of device 401, the second type of device 402, and the third type of device 403 in each pixel unit are arranged in the same manner. For example, the first type of device 401, the second type of device 402, and the third type of device 403 in any pixel unit can be arranged in sequence in the direction from the first column of touch control area TA to the ath column of touch control area TA.

[0208] In these optional embodiments, the shielding structure L2 and the touch line L1 are staggered with the pixel unit, that is, the first projection and the second projection do not pass through the fourth projection, so that the shielding structure L2 and the touch line L1 are only located between adjacent pixel units, so that the arrangement of the shielding structure L2 and the touch line L1 is not likely to affect the arrangement of the driving circuit 150 under the pixel unit, so that the spacing between the first type of device 401, the second type of device 402 and the third type of device 403 in the pixel unit can be arranged more closely, which is beneficial to improve the pixel arrangement density in the display panel 10 and improve the display effect of the display panel 10.

[0209] Optionally, the spacing between adjacent light-emitting devices 400 in a single pixel unit may be smaller than the spacing between adjacent pixel units, so as to facilitate the arrangement of the shielding structure L2 and the touch wiring L1 between adjacent pixel units.

[0210] See also Figures 1 to 9 The embodiment of the first aspect of the present application further provides a display panel 10, the display panel 10 has multiple touch areas TA, and the display panel 10 includes: a substrate 100; an isolation structure 300, which is arranged on one side of the substrate 100, and the isolation structure 300 encloses an isolation opening 300a and a receiving opening 300b; a light-emitting device 400, at least part of the structure of the light-emitting device 400 is located in the isolation opening 300a; a touch electrode 500, which is arranged in the receiving opening and insulated from the isolation structure 300, and the touch electrode 500 includes a plurality of sub-electrodes 501, the sub-electrodes 501 located in the same touch area TA are electrically connected to each other, the sub-electrodes 501 extend along a first direction X, and the plurality of sub-electrodes 501 located in the same touch area TA are spaced apart in a second direction Y; a shielding structure L2, which is located on a side of the touch electrode 500 facing the substrate 100, and the shielding structure L2 extends along the second direction Y, wherein the first direction X, the second direction Y and the thickness direction Z of the display panel 10 intersect each other.

By setting the shielding structure L2 to extend along the second direction Y, it is possible to facilitate a single shielding structure L2 to simultaneously participate in limiting the interference between the signals in the plurality of sub-electrodes 501 and the signals in the substrate 100, which can well improve the shielding efficiency of the shielding structure L2, and can facilitate the arrangement of the shielding structure L2, so that a large number of shielding structures L2 do not need to be set in the display panel 10, which can well improve the working stability of the display panel 10 and also improve the structural compactness of the display panel 10.
