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] OLED (Organic Light-Emitting Diode) has the characteristics of self-luminescence, high brightness, wide viewing angle, high contrast, flexibility, low energy consumption, etc., so it has received widespread attention. As a new generation of display method, it has gradually replaced traditional LCDs and is widely used in mobile phone screens, computer monitors, full-color TVs, etc. With the development of society and the advancement of technology, touch screen displays have become an indispensable part of modern electronic devices. In order to make the display screen thinner and lighter, incell technology is usually used.

[0003] In the process of traditional display panel preparation, the graphicization of luminous pixels is usually achieved through a fine metal mask (FMM). FMM technology is mature and has rich experience in mass production. However, FMM technology also has problems such as limited accuracy, high development cost, and long development cycle. The non-fine metal mask technology eliminates the limitations of traditional OLED processes on display screen size, resolution and other screen performance, and has the advantages of high performance, full-domain size, and agile delivery.

DETAILED DESCRIPTION

[0084] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.

[0085] It should be understood that although the terms "first", "second", etc. may be used herein to describe various elements, they do not represent any order, quantity or importance, but are only used to distinguish different components. These terms are only used to distinguish one element from another. For example, without departing from the scope of the present application, the first element may be referred to as the second element, and similarly, the second element may be referred to as the first element. "Include" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0086] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0087] In addition, in the specification, the phrase "planar distribution schematic diagram" refers to a drawing when the target part is observed from above, and the phrase "cross-sectional schematic diagram" or "cross-sectional structure schematic diagram" refers to a drawing when a section obtained by vertically cutting the target part is observed from the side.

[0088] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0089] In the related art, when the touch driving electrode and the isolation column are in the same layer in the display panel, the data line below is arranged in the same layer as the touch electrode, and the mutual interference between the data line and the touch electrode is relatively serious, resulting in poor touch performance of the display panel.

[0090] In view of the above problems, embodiments of the present application provide a display panel and a display device capable of improving touch performance.

[0091] Combination Figure 1-Figure 15 An embodiment of the present application provides a display panel 10, which may be an organic light emitting diode display panel 100 (Organic Light Emitting Diode, referred to as OLED) or a quantum dot electroluminescent display panel 100 (Quantum Dot Light Emitting Diodes, referred to as QLED).

[0092] Specifically, see Figure 1 and Figure 2 , the display panel 10 includes a substrate 100, a metal layer 200, an isolation layer 300 and a plurality of light-emitting units 400. The metal layer 200 is disposed on one side of the substrate 100, and the metal layer 200 includes a first data line 210a, a first touch electrode 220a and a first isolation line 230a that are spaced apart. That is, there is a gap between the first data line 210a and the first touch electrode 220a on the metal layer 200, there is a gap between the first touch electrode 220a and the first isolation line 230a, and there is also a gap between the first data line 210a and the first isolation line 230a.

[0093] The isolation layer 300 is disposed on a side of the metal layer 200 facing away from the substrate 100 . In addition, the isolation layer 300 includes an isolation structure 310 ; the isolation structure 310 encloses a plurality of isolation openings 301 .

[0094] The plurality of light emitting units 400 include one or more first light emitting units 410 , which are disposed adjacent to the first touch electrode 220 a . In other words, the orthographic projection of the first light emitting unit 410 on the substrate 100 is disposed adjacent to the orthographic projection of the first touch electrode 220 a on the substrate 100 .

[0095] The orthographic projection of the first light emitting unit 410 on the substrate 100 is located within the orthographic projection of the isolation opening 301 on the substrate 100. That is, the first light emitting unit 410 is formed in the isolation opening 301. Specifically, the first light emitting unit 410 is formed in at least one isolation opening 301.

[0096] Optionally, the orthographic projection of the first light emitting unit 410 on the substrate 100 and the orthographic projection of the first data line 210a on the substrate 100 have an overlapping area, in other words, along the thickness direction of the substrate 100, a portion of the first data line 210a is located directly below the first light emitting unit 410. The first data line 210a is used to transmit data to the pixel circuit corresponding to the first light emitting unit 410.

[0097] The orthographic projection of the first touch electrode 220a on the substrate 100 is spaced from the orthographic projection of the first isolation line 230a on the substrate 100. In other words, there is a gap between the orthographic projection of the first touch electrode 220a on the substrate 100 and the orthographic projection of the first isolation line 230a on the substrate 100.

[0098] Specifically, in the first direction X, from left to right, the orthographic projection of the first touch electrode 220a on the substrate 100, the orthographic projection of the first isolation line 230a on the substrate 100, and the orthographic projection of the first data line 210a on the substrate 100 are arranged in sequence. In addition, there is a gap between the first touch electrode 220a and the first isolation line 230a, and there is a gap between the first isolation line 230a and the first data line 210a.

[0099] The display panel 10 provided in the embodiment of the present application includes a substrate 100, a metal layer 200, an isolation layer 300, and a plurality of light-emitting units 400. The metal layer 200 is disposed on one side of the substrate 100, and includes a first data line 210a, a first touch electrode 220a, and a first isolation line 230a arranged at intervals; the isolation layer 300 is disposed on a side of the metal layer 200 away from the substrate 100, and includes an isolation structure 310, and the isolation structure 310 encloses a plurality of isolation openings 301. A first isolation line 230a is set between the first data line 210a and the first touch electrode 220a of the metal layer 200. In this way, the first isolation line 230a can play a shielding role and also increase the distance between the first data line 210a and the first touch electrode 220a, which can reduce the coupling capacitance between the first touch electrode 220a and the first data line 210a, thereby reducing the mutual interference between the first data line 210a and the first touch electrode 220a, and further improving the touch performance and display effect of the display panel 10.

[0100] In one embodiment, see Figure 3 The metal layer 200 further includes a first reference voltage line 240 a , the orthographic projection of the first reference voltage line 240 a on the substrate 100 is located between the orthographic projection of the first touch electrode 220 a on the substrate 100 and the orthographic projection of the first light emitting unit 410 on the substrate 100 .

[0101] In other words, there is a gap between the orthographic projection of the first touch electrode 220a on the substrate 100 and the orthographic projection of the first light-emitting unit 410 adjacent thereto on the substrate 100, and the orthographic projection of the first reference voltage line 240a on the substrate 100 is located within the orthographic projection of the gap on the substrate 100. The first reference voltage line 240a is disposed in the same layer as the first data line 210a and the first touch electrode 220a. The first reference voltage line 240a is used to transmit a reference voltage signal to a pixel circuit corresponding to the first light-emitting unit 410 in the display panel 10.

[0102] Specifically, in the first direction X, from left to right, the orthographic projection of the first touch electrode 220a on the substrate 100, the orthographic projection of the first reference voltage line 240a on the substrate 100, and the orthographic projection of the first light emitting unit 410 on the substrate 100 are arranged in sequence.

[0103] In an alternative embodiment, see Figure 2 and Figure 3 If the orthographic projection of the first data line 210a on the substrate 100 and the orthographic projection of the first light-emitting unit 410 on the substrate 100 have an overlapping area, then in the first direction X, from left to right, the orthographic projection of the first touch electrode 220a on the substrate 100, the orthographic projection of the first reference voltage line 240a on the substrate 100, and the orthographic projection of the first data line 210a on the substrate 100 are arranged in sequence.

[0104] In an alternative embodiment, see Figure 3 In the case where the metal layer 200 includes the first reference voltage line 240a, the first reference voltage line 240a is reused as the first isolation line 230a. In other words, the first reference voltage line 240a on the metal layer 200 is used as the first isolation line 230a to shield the first touch electrode 220a and the first data line 210a.

[0105] In the above embodiment, the first reference voltage line 240a can be used as a routing line for transmitting a reference voltage signal, and can also be used as a first isolation line 230a to reduce mutual interference between the first touch electrode 220a and the first data line 210a. Such a dual-purpose routing line can reduce the volume of the display panel 10 and improve the practicality of the display panel 10.

[0106] In one embodiment, see Figure 2 The metal layer 200 includes a first power signal line 250a, which is electrically connected to the first light emitting unit 410. That is, the first power signal line 250a is used to transmit a power signal to a pixel circuit corresponding to the first light emitting unit 410 in the display panel 10, so that the first light emitting unit 410 emits light.

[0107] In an alternative embodiment, see Figure 2 , the orthographic projection of the first power signal line 250a on the substrate 100 and the orthographic projection of the first light-emitting unit 410 on the substrate 100 have an overlapping area. The first power signal line 250a is arranged on the same layer as the first data line 210a and the first touch electrode 220a. Along the thickness direction of the substrate 100, a portion of the first power signal line 250a is located directly below the first light-emitting unit 410.

[0108] Specifically, in the first direction X, from left to right, the orthographic projection of the first touch electrode 220a on the substrate 100, the orthographic projection of the first power signal line 250a on the substrate 100, and the orthographic projection of the first data line 210a on the substrate 100 are arranged in sequence.

[0109] In an alternative embodiment, see Figure 2 In the case where the metal layer 200 includes the first power signal line 250a, the first power signal line 250a is reused as the first isolation line 230a. In other words, the first power signal line 250a on the metal layer 200 is used as the first isolation line 230a to shield the first touch electrode 220a and the first data line 210a.

[0110] In the above embodiment, the first power signal line 250a can be used as a routing line for transmitting a power signal, and can also be used as a first isolation line 230a for reducing mutual interference between the first touch electrode 220a and the first data line 210a. Such a dual-purpose routing line can reduce the volume of the display panel 10 and improve the practicality of the display panel 10. In addition, in the first direction X, from left to right, the first power signal line 250a and the first data line 210a are arranged in sequence, so that the first power signal line 250a can be used as the first isolation line 230a, so that the process of preparing the display panel 10 is simple, and the practicality of the display panel 10 can be improved.

[0111] In one embodiment, see Figure 2 The first data line 210a, the first touch electrode 220a and the first power signal line 250a are all extended along the second direction Y.

[0112] In the first direction X, the spacing distance between the first touch electrode 220a and the first power signal line 250a is greater than or equal to 3μm and less than or equal to 10μm. That is, the size of the gap between the first touch electrode 220a and the first power signal line 250a can be in the range of 3μm-10μm, and includes any value between 3μm and 10μm. For example, the size of the gap between the first touch electrode 220a and the first power signal line 250a can be 3μm, 3.5μm, 4.2μm, 4.5μm, 5μm, 5.5μm, 6.4μm, 7.8μm, 8μm, 8.6μm, 9.1μm or 10μm, etc. The first direction intersects with the second direction;

[0113] Optionally, the first direction and the second direction are perpendicular to each other.

[0114] Optionally, in the first direction X, the size of the first power signal line 250a is greater than or equal to twice the size of the first data line 210a. In other words, along the first direction X, the width of the first power signal line 250a is greater than or equal to twice the width of the first data line 210a.

[0115] In one embodiment, see Figure 3, the first data line 210a, the first touch electrode 220a and the first isolation line 230a are all extended along the second direction Y. In the first direction X, the spacing distance between the first touch electrode 220a and the first data line 210a is greater than or equal to 10μm and less than or equal to 100μm. In other words, the size of the gap between the first touch electrode 220a and the first data line 210a can be in the range of 10μm-100μm, and includes any value between 10μm and 100μm. For example, the size of the gap between the first touch electrode 220a and the first data line 210a can be 10μm, 16μm, 20μm, 30μm, 38μm, 40μm, 50μm, 55μm, 60μm, 66μm, 70μm, 80μm, 88μm, 90μm, 94μm or 100μm, etc.

[0116] In one embodiment, see Figure 3 , the metal layer 200 includes a first reference voltage line 240a and a first power signal line 250a, and in the first direction X, from left to right, the orthographic projection of the first touch electrode 220a on the substrate 100, the orthographic projection of the first reference voltage line 240a on the substrate 100, the orthographic projection of the first power signal line 250a on the substrate 100, and the orthographic projection of the first data line 210a on the substrate 100 are arranged in sequence. Alternatively, in the first direction X, from left to right, the orthographic projection of the first touch electrode 220a on the substrate 100, the orthographic projection of the first reference voltage line 240a on the substrate 100, the orthographic projection of the first data line 210a on the substrate 100, and the orthographic projection of the first power signal line 250a on the substrate 100 are arranged in sequence.

[0117] In one embodiment, see Figure 3 and Figure 4The metal layer 200 includes a first reference voltage line 240a and a first power signal line 250a, and the first reference voltage line 240a is multiplexed as a first isolation line 230a. The distance between the first power signal line 250a and the first touch electrode 220a is greater than the distance between the first data line 210a and the first touch electrode 220a; that is, the distance between the orthographic projection of the first power signal line 250a on the substrate 100 and the orthographic projection of the first touch electrode 220a on the substrate 100 is greater than the distance between the orthographic projection of the first data line 210a on the substrate 100 and the orthographic projection of the first touch electrode 220a on the substrate 100. Alternatively, in other embodiments, the distance between the first power signal line 250a and the first touch electrode 220a is smaller than the distance between the first data line 210a and the first touch electrode 220a; that is, the distance between the orthographic projection of the first power signal line 250a on the substrate 100 and the orthographic projection of the first touch electrode 220a on the substrate 100 is smaller than the distance between the orthographic projection of the first data line 210a on the substrate 100 and the orthographic projection of the first touch electrode 220a on the substrate 100.

[0118] That is to say, in the case where the metal layer 200 includes the first reference voltage line 240a and the first power signal line 250a, if the first reference voltage line 240a is used as the first isolation line 230a, then in the first direction X, the arrangement order of the first power signal line 250a and the first data line 210a can be swapped, that is, the arrangement order of the first data line 210a, the first touch electrode 220a, the first reference voltage line 240a and the first power signal line 250a can be: in the first direction X, from left to right, the first touch electrode 220a, the first reference voltage line 240a, the first data line 210a, and the first power signal line 250a are arranged in sequence; or it can be: in the first direction X, from left to right, the first touch electrode 220a, the first reference voltage line 240a, the first power signal line 250a, and the first data line 210a are arranged in sequence.

[0119] In the above embodiment, when the metal layer 200 includes both the first reference voltage line 240a and the first power signal line 250a, and the first reference voltage line 240a is used as the first isolation line 230a, the arrangement positions of the first reference voltage line 240a and the first data line 210a can be swapped, which can improve the practicality of the display panel 10.

[0120] In one embodiment, see Figure 3The metal layer 200 includes a first reference voltage line 240a and a first power signal line 250a, and the first power signal line 250a and the first reference voltage line 240a are both multiplexed as the first isolation line 230a. The distance between the first power signal line 250a and the first touch electrode 220a is smaller than the distance between the first data line 210a and the first touch electrode 220a, that is, the distance between the orthographic projection of the first power signal line 250a on the substrate 100 and the orthographic projection of the first touch electrode 220a on the substrate 100 is smaller than the distance between the orthographic projection of the first data line 210a on the substrate 100 and the orthographic projection of the first touch electrode 220a on the substrate 100.

[0121] That is to say, in the case where the metal layer 200 includes both the first reference voltage line 240a and the first power signal line 250a, if the first power signal line 250a and the first reference voltage line 240a are both used as the first isolation line 230a, then in the first direction X, from left to right, the first touch electrode 220a, the first reference voltage line 240a, the first power signal line 250a, and the first data line 210a are arranged in sequence.

[0122] In the above embodiment, when the metal layer 200 includes both the first reference voltage line 240a and the first power signal line 250a, the first reference voltage line 240a and the first power signal line 250a can be used as the first isolation line 230a, which can reduce the mutual interference between the first touch electrode 220a and the first data line 210a to a greater extent, thereby greatly improving the touch performance and display effect of the display panel 10.

[0123] In one embodiment, see Figure 5 , the metal layer 200 includes a second data line 210b, a second touch electrode 220b, and a second isolation line 230b that are spaced apart. That is, there is a gap between the second data line 210b and the second touch electrode 220b on the metal layer 200, there is a gap between the second touch electrode 220b and the second isolation line 230b, and there is also a gap between the second data line 210b and the second isolation line 230b.

[0124] The plurality of light emitting units 400 further includes at least one second light emitting unit 420. The second light emitting unit 420 is disposed adjacent to the second touch electrode 220b, that is, the orthographic projection of the second light emitting unit 420 on the substrate 100 is disposed adjacent to the orthographic projection of the second touch electrode 220b on the substrate 100.

[0125] Specifically, the distance between the orthographic projection of the second touch electrode 220b on the substrate 100 and the orthographic projection of the second light-emitting unit 420 on the substrate 100 is smaller than the distance between the orthographic projection of the second touch electrode 220b on the substrate 100 and the orthographic projection of the first light-emitting unit 410 on the substrate 100. Similarly, the distance between the orthographic projection of the first touch electrode 220a on the substrate 100 and the orthographic projection of the first light-emitting unit 410 on the substrate 100 is smaller than the distance between the orthographic projection of the first touch electrode 220a on the substrate 100 and the orthographic projection of the second light-emitting unit 420 on the substrate 100.

[0126] The orthographic projection of the second light emitting unit 420 on the substrate 100 is located within the orthographic projection of the isolation opening 301 on the substrate 100. In other words, the second light emitting unit 420 is formed in the isolation opening 301. Specifically, the second light emitting unit 420 is formed in at least one isolation opening 301. The second data line 210b is electrically connected to the second light emitting unit 420, and the second data line 210b is used to transmit data to the pixel circuit corresponding to the second light emitting unit 420.

[0127] Optionally, the orthographic projection of the second light emitting unit 420 on the substrate 100 overlaps with the orthographic projection of the second data line 210b on the substrate 100. In other words, along the thickness direction of the substrate 100, part of the second data line 210b is located directly below the second light emitting unit 420.

[0128] The orthographic projection of the second isolation line 230 b on the substrate 100 is located between the orthographic projection of the second data line 210 b on the substrate 100 and the orthographic projection of the second touch electrode 220 b on the substrate 100 .

[0129] Specifically, in the first direction, from right to left, the orthographic projection of the second touch electrode 220b on the substrate 100, the orthographic projection of the second isolation line 230b on the substrate 100, and the orthographic projection of the second data line 210b on the substrate 100 are arranged in sequence. In addition, there is a gap between the second touch electrode 220b and the second isolation line 230b, and there is a gap between the second isolation line 230b and the second data line 210b.

[0130] The metal layer 200 provided in this embodiment includes second data lines 210b, second touch electrodes 220b and second isolation lines 230b which are arranged at intervals, and the plurality of light-emitting units 400 further includes a second light-emitting unit 420. The second isolation line 230b is arranged between the second data line 210b and the second touch electrode 220b of the metal layer 200, so that the second isolation line 230b can play a shielding role, and can reduce the coupling capacitance between the second touch electrode 220b and the second data line 210b, thereby reducing the mutual interference between the second data line 210b and the second touch electrode 220b, and further can improve the touch performance and display effect of the display panel 10.

[0131] In one embodiment, see Figure 5 The metal layer 200 includes a second reference voltage line 240 b , and the orthographic projection of the second reference voltage line 240 b on the substrate 100 is located between the orthographic projection of the second touch electrode 220 b on the substrate 100 and the orthographic projection of the second light emitting unit 420 on the substrate 100 .

[0132] In other words, there is a gap between the orthographic projection of the second touch electrode 220b on the substrate 100 and the orthographic projection of the second light-emitting unit 420 adjacent thereto on the substrate 100, and the orthographic projection of the second reference voltage line 240b on the substrate 100 is located within the gap. The second reference voltage line 240b is disposed in the same layer as the second data line 210b and the second touch electrode 220b. The second reference voltage line 240b is used to transmit a reference voltage signal to a pixel circuit corresponding to the second light-emitting unit 420 in the display panel 10.

[0133] Specifically, in the first direction X, from right to left, the orthographic projection of the second touch electrode 220 b on the substrate 100 , the orthographic projection of the second reference voltage line 240 b on the substrate 100 , and the orthographic projection of the second light emitting unit 420 on the substrate 100 are arranged in sequence.

[0134] In an alternative embodiment, see Figure 5 If the orthographic projection of the second data line 210b on the substrate 100 and the orthographic projection of the second light-emitting unit 420 on the substrate 100 have an overlapping area, then in the first direction X, from right to left, the orthographic projection of the second touch electrode 220b on the substrate 100, the orthographic projection of the second reference voltage line 240b on the substrate 100, and the orthographic projection of the second data line 210b on the substrate 100 are arranged in sequence.

[0135] In one embodiment, see Figure 5In the case where the metal layer 200 includes the second reference voltage line 240b, the second reference voltage line 240b is reused as the second isolation line 230b. In other words, the second reference voltage line 240b on the metal layer 200 is used as the second isolation line 230b to shield the second touch electrode 220b and the second data line 210b.

[0136] In the above embodiment, the second reference voltage line 240b can be used as a routing line for transmitting a reference voltage signal, and can also be used as a second isolation line 230b for reducing mutual interference between the second touch electrode 220b and the second data line 210b. Such a dual-purpose routing line can reduce the volume of the display panel 10 and improve the practicality of the display panel 10.

[0137] In one embodiment, see Figure 6 The metal layer 200 further includes a second power signal line 250b, which is electrically connected to the second light emitting unit 420. The second power signal line 250b is disposed in the same layer as the second data line 210b and the second touch electrode 220b.

[0138] In an optional embodiment, the orthographic projection of the second power signal line 250 b on the substrate 100 is located between the orthographic projection of the second touch electrode 220 b on the substrate 100 and the orthographic projection of the second light emitting unit 420 on the substrate 100 .

[0139] In an optional embodiment, the orthographic projection of the second power signal line 250b on the substrate 100 is located in an overlapping area with the orthographic projection of the second light emitting unit 420 on the substrate 100. That is, along the thickness direction of the substrate 100, a portion of the second power signal line 250b is located directly below the second light emitting unit 420, and the second power signal line 250b is used to transmit a power signal to a pixel circuit corresponding to the second light emitting unit 420 in the display panel 10.

[0140] Specifically, in the first direction X, from right to left, the orthographic projection of the second touch electrode 220 b on the substrate 100 , the orthographic projection of the second power signal line 250 b on the substrate 100 , and the orthographic projection of the second data line 210 b on the substrate 100 are arranged in sequence.

[0141] In one embodiment, see Figure 6 In the case where the metal layer 200 includes the second power signal line 250b, the second power signal line 250b is reused as the second isolation line 230b. In other words, the second power signal line 250b on the metal layer 200 is used as the second isolation line 230b to shield the second touch electrode 220b and the second data line 210b.

[0142] In the above embodiment, the second power signal line 250b can be used as a routing line for transmitting power signals, and can also be used as a second isolation line 230b for reducing mutual interference between the second touch electrode 220b and the second data line 210b. Such a dual-purpose routing line can reduce the volume of the display panel 10 and improve the practicality of the display panel 10.

[0143] In one embodiment, see Figure 6 The second data line 210b, the second touch electrode 220b, and the second power signal line 250b are all extended along the second direction Y.

[0144] In the first direction X, the spacing distance between the second touch electrode 220b and the second power signal line 250b is greater than or equal to 3 microns and less than or equal to 10 microns. That is, the size of the gap between the second touch electrode 220b and the second power signal line 250b can be in the range of 3μm-10μm, and includes any value between 3μm and 10μm. For example, the size of the gap between the second touch electrode 220b and the second power signal line 250b is 3μm, 3.5μm, 4μm, 4.5μm, 5μm, 5.5μm, 6.4μm, 7.8μm, 8μm, 8.6μm, 9.1μm or 10μm, etc.

[0145] Optionally, in the first direction X, the size of the second power signal line 250b is greater than or equal to twice the size of the second data line 210b. In other words, along the first direction X, the width of the second power signal line 250b is greater than or equal to twice the width of the second data line 210b.

[0146] In one embodiment, see Figure 5 The second data line 210b, the second touch electrode 220b and the second isolation line 230b are all extended along the second direction Y.

[0147] In the first direction X, the spacing distance between the second touch electrode 220b and the second data line 210b is greater than or equal to 10 microns and less than or equal to 100 microns. That is, the size of the gap between the second touch electrode 220b and the second data line 210b can be in the range of 10μm-100μm, and includes any value between 10μm and 100μm. For example, the size of the gap between the second touch electrode 220b and the second data line 210b can be 10μm, 16μm, 23μm, 30μm, 36μm, 44μm, 50μm, 55μm, 60μm, 66μm, 73μm, 85μm, 90μm, 94μm or 100μm, etc.

[0148] In one embodiment, see Figure 5, the metal layer 200 includes a second reference voltage line 240b and a second power signal line 250b, and in the first direction X, from right to left, the orthographic projection of the second touch electrode 220b on the substrate 100, the orthographic projection of the second reference voltage line 240b on the substrate 100, the orthographic projection of the second power signal line 250b on the substrate 100, and the orthographic projection of the second data line 210b on the substrate 100 are arranged in sequence. Alternatively, in the first direction X, from right to left, the orthographic projection of the second touch electrode 220b on the substrate 100, the orthographic projection of the second reference voltage line 240b on the substrate 100, the orthographic projection of the second data line 210b on the substrate 100, and the orthographic projection of the second power signal line 250b on the substrate 100 are arranged in sequence.

[0149] In one embodiment, see Figure 5 and Figure 7 The metal layer 200 includes a second reference voltage line 240b and a second power signal line 250b; the second reference voltage line 240b is reused as a second isolation line 230b. The distance between the second power signal line 250b and the second touch electrode 220b is greater than the distance between the second data line 210b and the second touch electrode 220b; that is, the distance between the orthographic projection of the second power signal line 250b on the substrate 100 and the orthographic projection of the second touch electrode 220b on the substrate 100 is greater than the distance between the orthographic projection of the second data line 210b on the substrate 100 and the orthographic projection of the second touch electrode 220b on the substrate 100. Alternatively, the distance between the second power signal line 250b and the second touch electrode 220b is smaller than the distance between the second data line 210b and the second touch electrode 220b; that is, the distance between the orthographic projection of the second power signal line 250b on the substrate 100 and the orthographic projection of the second touch electrode 220b on the substrate 100 is smaller than the distance between the orthographic projection of the second data line 210b on the substrate 100 and the orthographic projection of the second touch electrode 220b on the substrate 100.

[0150] That is to say, in the case where the metal layer 200 includes the second reference voltage line 240b and the second power signal line 250b, if the second reference voltage line 240b is used as the second isolation line 230b, in the first direction X, the arrangement order of the second power signal line 250b and the second data line 210b can be exchanged, that is, the arrangement order of the second data line 210b, the second touch electrode 220b, the second reference voltage line 240b and the second power signal line 250b can be: in the first direction X, from right to left, the second touch electrode 220b, the second reference voltage line 240b, the second data line 210b, and the second power signal line 250b are arranged in sequence; it can also be that in the first direction X, from right to left, the second touch electrode 220b, the second reference voltage line 240b, the second power signal line 250b, and the second data line 210b are arranged in sequence.

[0151] In the above embodiment, when the metal layer 200 includes both the second reference voltage line 240b and the second power signal line 250b, and the second reference voltage line 240b is used as the second isolation line 230b, the arrangement positions of the second reference voltage line 240b and the second data line 210b can be swapped, which can improve the practicality of the display panel 10.

[0152] In one embodiment, see Figure 5 The metal layer 200 includes a second reference voltage line 240b and a second power signal line 250b, and the second power signal line 250b and the second reference voltage line 240b are both reused as the second isolation line 230b. The distance between the second power signal line 250b and the second touch electrode 220b is smaller than the distance between the second data line 210b and the second touch electrode 220b, that is, the distance between the orthographic projection of the second power signal line 250b on the substrate 100 and the orthographic projection of the second touch electrode 220b on the substrate 100 is smaller than the distance between the orthographic projection of the second data line 210b on the substrate 100 and the orthographic projection of the second touch electrode 220b on the substrate 100.

[0153] That is to say, when the metal layer 200 includes both the second reference voltage line 240b and the second power signal line 250b, if the second power signal line 250b and the second reference voltage line 240b are both used as the second isolation line 230b, then in the first direction X, from right to left, the second touch electrode 220b, the second reference voltage line 240b, the second power signal line 250b, and the second data line 210b are arranged in sequence.

[0154] In the above embodiment, when the metal layer 200 includes both the second reference voltage line 240b and the second power signal line 250b, the second reference voltage line 240b and the second power signal line 250b can be used as the second isolation line 230b, which can reduce the mutual interference between the second touch electrode 220b and the second data line 210b to a greater extent, thereby greatly improving the touch performance and display effect of the display panel 10.

[0155] In one embodiment, see Figure 8 and Fig. 9 The metal layer 200 includes a third data line 210c and a third power signal line 250c that are spaced apart from each other. That is, there is a gap between the third data line 210c and the third power signal line 250c on the metal layer 200.

[0156] The plurality of light-emitting units 400 further include at least one third light-emitting unit 430, and the orthographic projection of the third light-emitting unit 430 on the substrate 100 is located within the orthographic projection of the isolation opening 301 on the substrate 100.
