[0081] Reference Figure 1-2As shown, it is a schematic diagram of the structure of a related display panel, which includes a substrate 1 and an isolation structure 2 arranged on one side of the substrate 1, the isolation structure 2 encloses a limited opening 21 for accommodating the light-emitting unit 5, and adjacent light-emitting units 5 are separated by the isolation structure 2.

[0082] Among them, an isolation structure 2 is set at the gap between the light-emitting units 5 to separate the functional film layers of adjacent light-emitting units 5. In this way, in the evaporation process of multiple functional film layers, it is only necessary to perform evaporation on the entire surface of the display panel, without the need to use a mask plate to evaporate the area where the light-emitting unit 5 is located to form a functional film layer. Therefore, the process of evaporation using the isolation structure 2 does not need to consider the positioning accuracy during evaporation, so that the gap between the light-emitting units 5 can be designed to be smaller in size to increase the pixel density.

[0083] At the same time, the display panel 100 also includes a display area 110, and the display area 110 includes a first area 101. The first area 101 is used for under-screen recognition, video recording or transparent display, etc. Therefore, the first area 101 needs to have a certain light transmittance.

[0084] After long-term research, the inventors found that the large area of ​​metal in the isolation structure 2 is opaque, which will affect the transmittance of the display panel 100, especially in the first area 101 which has high requirements for transmittance. If the transmittance cannot meet the requirements, it will affect the under-screen recognition, camera or transparent display functions in this area.

[0085] Based on this, the present application provides a display panel solution, as detailed in the following embodiments.

[0086] Reference Figure 1 and 3 As shown, an embodiment of the present application discloses a display panel 100, which includes a substrate 1, a limiting structure 10 and a touch layer 3.

[0087] The definition of the opening 21 for accommodating the light-emitting unit 5 can be understood as the definition of the opening 21 accommodating the entire light-emitting unit 5, or can be understood as the definition of the opening 21 accommodating a major portion of the light-emitting unit 5, which determines the position of the main light-emitting area of ​​the light-emitting unit 5. The light-transmitting opening 22 can make the area where the light-transmitting opening 22 is located transparent to facilitate under-screen recognition (such as fingerprint recognition, camera, etc.) or transparent display, etc.

[0088] The display panel 100 provided in this embodiment prevents the touch wiring 4 from blocking the limiting opening 21 or the light-transmitting opening 22 by positioning the orthographic projection of part of the touch wiring 4 on the substrate 1 between the orthographic projection of the limiting opening 21 on the substrate 1, and the orthographic projection of the touch wiring 4 on the substrate 1 is located within the orthographic projection of the limiting structure 10 on the substrate 1, thereby ensuring the light transmittance of the display panel 100; at the same time, due to the isolation effect of the metal in the limiting structure 10, crosstalk between the touch wiring 4 and the wiring in the substrate 1 can be avoided, thereby improving the display performance of the display panel 100.

Specifically, in the first direction, since the size of the gap between two adjacent first type of defined openings 211 is different from the size of the gap between the second type of defined openings 212 and the third type of defined openings 213, the sizes of the first type of light-transmitting openings 221 and the second type of light-transmitting openings 222 can be designed according to the size of the gaps in which they are located, and their sizes can be different.

[0098] Preferably, along the first direction, the size of the first type of light-transmitting opening 221 is larger than the size of the second type of light-transmitting opening 222. Specifically, since in the first direction, the gap between two adjacent first type of defined openings 211 is larger, and the gap between the second type of defined opening 212 and the third type of defined opening 213 is smaller, the size of the first type of light-transmitting opening 221 is larger than the size of the second type of light-transmitting opening 222, which can effectively improve the light transmittance.

[0099] Please continue to refer to Figure 8 As shown, in one embodiment, the touch wiring 4 includes a plurality of first wirings 43 arranged along the second direction, the first wirings 43 extend along the first direction, the touch wiring 4 includes a plurality of second wirings 44, the second wirings 44 extend along the second direction, and the second wirings 44 located in the same row and extending along the second direction are connected to each other.

[0100] Preferably, the orthographic projection of the first wiring 43 on the substrate 1 is located between the orthographic projections of the adjacent first-type defined openings 211 and the second-type defined openings 212 on the substrate 1, and between the orthographic projections of the adjacent first-type defined openings 211 and the third-type defined openings 213 on the substrate 1; at least part of the orthographic projection of the second wiring 44 on the substrate 1 is located between the adjacent first-type defined openings 211, and the orthographic projection of the second wiring 44 on the substrate 1 does not overlap with the orthographic projection of the first-type light-transmitting openings 221 on the substrate 1. Ensure that the touch wiring 4 is distributed in different areas on the display panel to realize the touch function of different areas, and avoid the touch wiring 4 from blocking the defined openings.

The orthographic projection of the virtual line 45 on the substrate 1 is located within the orthographic projection of the isolation structure 2 between the second type of defined opening 212 and the third type of defined opening 213 on the substrate 1. Among them, since the virtual line 45 does not transmit signals to other second lines, it is beneficial to reduce the touch line load and ensure the uniformity of the graphics, thereby improving the display effect. In one embodiment, the two ends of the virtual line 45 are insulated and are not electrically connected to the first line 43. In another embodiment, the virtual line 45 is connected to the power signal line, and the power signal line can provide a stable fixed potential, which helps to improve the performance and stability of the circuit. Specifically, the virtual line 45 is connected to the positive power signal line ELVDD, or to the negative power signal line ELVSS.

[0103] Please continue to refer to Fig. 9 As shown, in one embodiment, the first virtual routing line 451 and the second virtual routing line 452 are arranged along a first direction.

[0104] Preferably, at least part of the first routing line 43 is disposed at two ends of the first virtual routing line 451 or the second virtual routing line 452 close to the first type of defined opening 211 , and at least one end of the first virtual routing line 451 or the second virtual routing line 452 is insulated from the first routing line 43 .

[0105] In the first direction, refer to Figure 5 , there is a first distance Q between the orthographic projection of the second routing line 44 on the substrate 1 and the orthographic projection of the adjacent first-type defined opening 211 on the substrate 1 facing the edge of the second routing line 44, there is a second distance between the orthographic projection of the first virtual routing line 451 on the substrate 1 and the orthographic projection of the adjacent second-type defined opening 212 on the substrate 1 facing the edge of the first virtual routing line 451, and there is a third distance between the orthographic projection of the second virtual routing line 452 on the substrate 1 and the orthographic projection of the adjacent third-type defined opening 213 on the substrate 1 facing the edge of the second virtual routing line 452; the first distance is equal to the second distance or the third distance, wherein the adjacent first-type defined opening 211 is the first-type defined opening 211 closest to the second routing line 44, and the adjacent second-type defined opening 212 is the second-type defined opening 212 closest to the first virtual routing line 451, further ensuring the uniformity of the distribution of the touch routing lines 4, ensuring the uniformity of the luminous environments of the first-type defined openings 211 and the second-type defined openings 212, thereby improving the display effect.

[0106] Preferably, the first virtual wiring 451 and the second virtual wiring 452 are symmetrically arranged with respect to the second type of light-transmitting opening 222 , which is beneficial to further reduce the risk of color deviation and improve display uniformity.

At this time, when the third routing line 46 is connected to the second routing line 44 in the same row or an adjacent row, it needs to be connected through a via hole in the line-changing layer at the intersection with the first routing line 43. Specifically, when the third routing line 46 and the second routing line 44 are not aligned in the second direction, the third routing line 46 and the second routing line 44 are directly connected through a via hole in the line-changing layer. When the third routing line 46 and the second routing line 44 are aligned in the second direction, the third routing line 46 needs to extend a distance in the direction of the second routing line 44 and then connect to the second routing line 44 through a via hole in the line-changing layer, or the second routing line 44 turns in the direction of the third routing line 46 and then connects to the third routing line 46 through a via hole in the line-changing layer.

[0109] Preferably, the third routing line 46 and the second type of light-transmitting opening 222 are arranged along the first direction with the second type of defined opening 212 or the third type of defined opening 213 spaced apart, that is, the second type of light-transmitting opening 222 and the virtual routing line 45 are arranged between the second type of defined opening 212 and the third type of defined opening 213 on one side, and the third routing line 46 is arranged between the second type of defined opening 212 and the third type of defined opening 213 on the other side, which is conducive to achieving a balance between ensuring the touch function and reducing the routing load.

[0110] Please continue to refer to Figure 4 and 5 As shown, in one embodiment, the limiting structure 10 includes an isolation structure 2 disposed on one side of the substrate, the isolation structure 2 includes a support portion 23 and a crown portion 24, the crown portion 24 is located on the side of the support portion 23 away from the substrate 1, and the orthographic projection of one end of the support portion 23 facing the crown portion 24 on the substrate 1 is located within the orthographic projection of the crown portion 24 on the substrate 1; wherein the support portion 23 is a conductive structure, and the light-emitting unit 5 is electrically connected to the support portion 23. Further, the second electrode 53 is electrically connected to the support portion 23. Optionally, the first electrode 51 is an anode, and the second electrode 53 is a cathode.

The first crown portion opening 241 is located on a side of the first support portion opening 231 away from the substrate 1, the positions of the first support portion opening 231 and the first crown portion opening 241 are different, and the sizes of the first support portion opening 231 and the first crown portion opening 241 can be different. Similarly, the second crown portion opening 242 is located on a side of the second support portion opening 232 away from the substrate 1, the positions of the second support portion opening 232 and the second crown portion opening 242 are different, and the sizes of the second support portion opening 232 and the second crown portion opening 242 can be different. The third crown opening 243 is located at a side of the third support opening 233 away from the substrate 1 . The third support opening 233 and the third crown opening 243 are at different positions and may have different sizes.

[0112] Preferably, refer to Figure 5 In the first direction, the orthographic projection of the second line 44 on the substrate 1 and the orthographic projection of the adjacent first crown 24 opening on the substrate 1 facing the edge of the second line 44 have a fourth distance M, the orthographic projection of the first virtual line 451 on the substrate 1 and the orthographic projection of the adjacent second crown opening 242 on the substrate 1 facing the edge of the first virtual line 451 have a fifth distance, and the orthographic projection of the second virtual line 452 on the substrate 1 and the orthographic projection of the adjacent third crown opening 243 on the substrate 1 facing the edge of the second virtual line 452 have a sixth distance; the fourth distance is equal to the fifth distance or the sixth distance. The uniformity of the graphics is further ensured, thereby improving the display effect.

[0113] It should be noted that the material of the second electrode 53 can be a metal material. The smaller the thickness of the second electrode 53, the higher its transmittance, but the higher its resistivity. If the thickness of the second electrode 53 is too small, when the isolation structure 2 is not set, the voltage drop of the second electrode 53 (the common electrode at this time) will be too large. In this embodiment, the second electrode 53 is connected to the conductive support part 23, which can remove the thickness restriction of the second electrode 53, so that the second electrode 53 has a smaller thickness to have a higher transmittance.

[0114] Please continue to refer to Figure 4As shown, in one embodiment, the defining structure 10 includes a pixel defining layer 6 located on one side of the substrate 1 and an isolation structure 2 located on the side of the pixel defining layer 6 facing away from the substrate 1, the isolation structure 2 encloses a plurality of isolation openings 25 and a light-transmitting opening 22, the pixel defining layer 6 defines a plurality of pixel openings 61 corresponding to the isolation openings 25, the pixel openings 61 are connected to the corresponding isolation openings 25, and the orthographic projection of the pixel opening 61 on the substrate 1 is located within the orthographic projection of the corresponding isolation opening 25 on the substrate 1.

[0115] Among them, the isolation structure 2 separates the functional film layers of adjacent light-emitting units 5. In this way, in the evaporation process of multiple functional film layers, it is only necessary to perform evaporation on the entire surface of the display panel, without the use of a mask plate to evaporate the area where the light-emitting unit 5 is located to form a functional film layer. Therefore, the process of evaporation using the isolation structure 2 does not need to consider the positioning accuracy during evaporation, so that the gap between the light-emitting units 5 can be designed to be smaller in size to increase the pixel density.

Thus, the first electrode 51 can have a larger design area without contacting the support portion 23, so that the light-emitting unit 5 has a larger effective light-emitting area.

[0117] Preferably, the light emitting functional layer 52 and the second electrode 53 are located in the defined opening 21 , and the defined opening 21 includes the isolation opening 25 and the pixel opening 61 .

The second encapsulation layer is located between the first encapsulation layer and the third encapsulation layer. The first encapsulation layer and the third encapsulation layer are inorganic layers. The inorganic layers have high density to isolate water and oxygen. The second encapsulation layer is an organic layer, so it has a large thickness to flatten the surface of the display panel, thereby realizing inorganic-organic-inorganic three-layer encapsulation.

The limiting structure 10 is arranged on one side of the substrate 1. The limiting structure 10 encloses a limiting opening 21 and a light-transmitting opening 22.

In the same direction, the distance between the light-emitting units closest to the first virtual line 451 and the second line 44 is the same, ensuring consistent light-emitting effects.

[0125] The display panel 100 provided in this embodiment prevents the touch wiring 4 from blocking the limiting opening 21 or the light-transmitting opening 22 by positioning the orthographic projection of part of the touch wiring 4 on the substrate 1 between the orthographic projection of the limiting opening 21 on the substrate 1, and the orthographic projection of the touch wiring 4 on the substrate 1 is located within the orthographic projection of the limiting structure 10 on the substrate 1, thereby ensuring the light transmittance of the display panel 100; at the same time, due to the isolation effect of the metal in the limiting structure 10, crosstalk between the touch wiring 4 and the wiring in the substrate 1 can be avoided, thereby improving the display performance of the display panel 100.

[0126] Among them, the virtual line 45 is conducive to reducing the line load and can ensure the uniformity of the pattern, thereby improving the display effect. At the same time, the distance between the orthographic projection of the first virtual line 451 on the substrate 1 and the orthographic projection of the adjacent defined opening 21 on the substrate 1 is equal to the distance between the orthographic projection of the second line 44 on the substrate 1 and the orthographic projection of the adjacent defined opening 21 on the substrate 1, which can ensure the uniformity of the pattern, thereby improving the display effect.

[0129] In the display device of the present embodiment, the display panel 100 prevents the touch wiring 4 from blocking the limiting opening 21 or the light-transmitting opening 22 by locating the orthographic projection of the touch wiring 4 on the substrate 1 within the orthographic projection of the limiting structure 10 on the substrate 1, thereby ensuring the light transmittance of the display panel 100; at the same time, due to the isolation effect of the metal in the limiting structure 10, crosstalk between the touch wiring 4 and the wiring in the substrate 1 can be avoided, thereby improving the performance of the display device.
