Display panel and display device Technical Field

[0001] This invention relates to the field of display technology, and more specifically, to a display panel and a display device. Background Technology

Detailed Implementation

[0058] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted. Furthermore, the drawings are merely illustrative of the invention and are not necessarily drawn to scale.

[0059] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0060] The terms “a,” “one,” “the,” “the,” and “at least one” are used to indicate the presence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first,” “second,” and “third,” etc., are used only as markers and are not a limitation on the number of objects.

[0061] To enhance user experience, display devices are evolving towards full-screen designs, with punch-hole displays being a key trend. This involves creating openings in the display panel to increase the screen-to-body ratio. To further reduce power consumption, stacked light-emitting devices are used in the emissive layer. This reduces the luminous current while maintaining the same brightness, thus lowering power consumption. However, because stacked light-emitting devices experience greater crosstalk, it's necessary to isolate the emissive layer from the common electrode to minimize the impact of crosstalk on the display.

[0062] For punch-hole displays, to achieve better power-off effect in the non-display area between the hole and the display area, a step can be set on the side of the insulating layer away from the substrate to isolate the common electrode extending to the non-display area, thus better preventing black spots (GDSH) at the hole edge. However, since the common electrode around the hole is isolated, forming a suspended part, the suspended part between the touch trace and the back panel trace has no shielding effect. When the screen is not lit, the touch function is normal. When the screen is lit, the touch signal loaded on the touch trace and the light emission control signal of the light emission control trace 24 have crosstalk, resulting in greater interference to the touch signal transmission, thus causing the touch screen to fluctuate.

[0063] Based on this, the present invention provides a display panel. As shown in Figures 1 to 26, the display panel has a display area 100 and a non-display area 200 arranged adjacently. The non-display area 200 is adjacent to the outside. The display panel includes a driving backplate, an insulating layer group, a common electrode 163, and a touch control layer 18. The driving backplate includes a substrate 11 and light-emitting control lines 24, with the light-emitting control lines 24 disposed on one side of the substrate 11. The insulating layer group is disposed on the side of the light-emitting control lines 24 away from the substrate 11. The side of the insulating layer group away from the substrate 11 has a step, which is located in the non-display area 200. The two sides of the step closest to the display area 100 are a first region 2003 and a second region 200, respectively. 04; The common electrode 163 is disposed on the side of the insulating layer group away from the driving backplate. The common electrode 163 is separated by the step closest to the display area 100, forming a conductive part 164 and a suspended part 165; The touch control layer 18 is disposed on the side of the common electrode 163 away from the substrate 11. The touch control layer 18 includes an effective touch part 1821; The orthographic projection of the conductive part 164 on the substrate 11, the orthographic projection of the light-emitting control line 24 on the substrate 11 and / or the orthographic projection of the effective touch part 1821 on the substrate 11 overlap in the first region 2003, and the orthographic projection of the suspended part 165 on the substrate 11 is located in the second region 2004.

[0064] The common electrode 163 is interrupted at the step difference, forming a conductive portion 164 and a suspended portion 165. The suspended portion 165 can reduce the electro-erosion of the non-display area 200 and ensure normal display effect. The orthographic projection of the conductive portion 164 on the substrate 11, the orthographic projection of the light-emitting control trace 24 on the substrate 11, and / or the orthographic projection of the effective touch portion 1821 on the substrate 11 overlap in the first region 2003, and the orthographic projection of the suspended portion 165 on the substrate 11 is located in the second region 2004. The conductive portion 164 between the touch trace and the back panel trace acts as a shield to avoid crosstalk between the touch trace and the back panel trace, thereby reducing or eliminating interference to the touch signal and preventing touch screen reporting floating.

[0065] The display panel involved in the embodiments of the present invention will be described in detail below with reference to specific examples.

[0066] As shown in Figure 1, the display panel generally includes a substrate 11, a driving circuit layer 13, and a light-emitting layer 16. The driving circuit layer 13 is disposed on one side of the substrate 11, and the light-emitting layer 16 is disposed on the side of the driving circuit layer 13 away from the substrate 11. In addition, the display panel may also include a buffer layer 12, which may be disposed between the substrate 11 and the driving circuit layer 13.

[0067] The substrate 11 can be an inorganic material substrate 11 or an organic material substrate 11. For example, in one embodiment of this disclosure, the material of the substrate 11 can be a glass material such as soda-lime glass, quartz glass, or sapphire glass, or a metal material such as stainless steel, aluminum, or nickel.

[0068] In another embodiment of this disclosure, the substrate 11 may also be a flexible substrate 11, for example, the material of the substrate 11 may be polyimide (PI). The substrate 11 may also be a composite of multiple materials. For example, in one embodiment of this disclosure, the substrate 11 may include a bottom film layer, a pressure-sensitive adhesive layer, a first polyimide layer and a second polyimide layer stacked sequentially.

[0069] In the display area 100, the driving circuit layer 13 is provided with a driving circuit for driving the light-emitting unit 160. The driving circuit is located in the display area 100, and any driving circuit may include a transistor, which can be a thin-film transistor (TFT). The TFT can be selected from top-gate TFTs, bottom-gate TFTs, or dual-gate TFTs. Taking a top-gate TFT as an example, the TFT may include an active layer 131, a first gate 1331, a second gate 1332, a first gate insulating layer 1321, a second gate insulating layer 1322, and source / drain electrodes 136, wherein:

The material of the active layer 131 can be amorphous silicon semiconductor material, low-temperature polycrystalline silicon semiconductor material, metal oxide semiconductor material, organic semiconductor material, or other types of semiconductor material. Therefore, the thin film transistor can be an N-type thin film transistor or a P-type thin film transistor. The active layer 131 may include a channel region and two doped regions with different doping types located on both sides of the channel region.

[0071] A first gate insulating layer 1321 is disposed on the side of the active layer 131 away from the substrate 11. The first gate insulating layer 1321 can cover the active layer 131 and the substrate 11. A first gate 1331 is disposed on the side of the first gate insulating layer 1321 away from the substrate 11 and is directly opposite to the active layer 131. That is, the projection of the first gate 1331 on the substrate 11 is within the projection range of the active layer 131 on the substrate 11. For example, the projection of the first gate 1331 on the substrate 11 coincides with the projection of the channel region of the active layer 131 on the substrate 11. A second gate insulating layer 1322 is disposed on the side of the first gate 1331 away from the substrate 11. The second gate insulating layer 1322 can cover the first gate 1331 and the first gate insulating layer 1321. The second gate 1332 is disposed on the side of the second gate insulating layer 1322 away from the substrate 11 and is directly opposite to the active layer 131. The first gate insulating layer 1321 and the second gate insulating layer 1322 are both made of insulating materials such as silicon oxide.

[0072] The thin-film transistor may further include an interlayer dielectric layer 134, which is disposed on the side of the second gate 1332 away from the substrate 11. The interlayer dielectric layer 134 may cover the second gate 1332 and the second gate insulating layer 1322, and both interlayer dielectric layers 134 are made of insulating material. Source and drain electrodes 136 are disposed on the surface of the interlayer dielectric layer 134 away from the substrate 11, and the source and drain electrodes 136 include a first source electrode 135 and a drain electrode 136. The first source electrode 135 and the drain electrode 136 are connected to the active layer 131. For example, the first source electrode 135 and the drain electrode 136 are respectively connected to two doped regions of the corresponding active layer 131 through vias.

[0073] A planarization layer 14 is provided on the side of the source / drain electrode 136 away from the substrate 11. The planarization layer 14 may include a first planarization layer 141, and the surface of the first planarization layer 141 away from the substrate 11 is planar. The source / drain electrode 136 may also include a second source electrode 138, which is connected to the first source electrode 135. A second planarization layer 142 is provided on the side of the second source electrode 138 away from the substrate 11, covering the second source electrode 138 and the first planarization layer 141. A protective layer 137 may also be provided on the side of the first source electrode 135 away from the substrate 11, covering the first source electrode 135 and the drain electrode 136. The first planarization layer 141 covers the protective layer 137. It should be noted that the first source electrode 135 and the drain electrode 136 are located in the first source / drain metal layer of the driving circuit layer 13, and the second source electrode 138 is located in the second source / drain metal layer of the driving circuit layer 13.

[0074] A pixel defining layer 15 is disposed on the side of the first planarization layer 141 or the second planarization layer 142 away from the array substrate. The pixel defining layer 15 has multiple pixel openings 151. The light-emitting layer 16 may include multiple light-emitting units 160, each disposed within a different pixel opening 151. Each light-emitting unit 160 may include a pixel electrode 161, a light-emitting element 162, and a common electrode 163. The pixel electrode 161 is located on the surface of the first planarization layer 141 or the second planarization layer 142 away from the substrate 11. The light-emitting element 162 is disposed on the surface of the pixel electrode 161 away from the substrate 11, and the common electrode 163 is disposed on the surface of the light-emitting element 162 away from the substrate 11. The light-emitting element 162 can be driven to emit light through the pixel electrode 161 and the common electrode 163 to display an image.

[0075] Pixel electrode 161 is connected to either the first source 135 or the second source 138. A pixel defining layer 15 is provided on the side of pixel electrode 161 away from the substrate 11. When the thin-film transistor includes only the first source 135, pixel electrode 161 is connected to the first source 135, and the pixel defining layer 15 covers pixel electrode 161 and the first planarization layer 141. When the thin-film transistor also includes the second source 138, pixel electrode 161 is connected to the second source 138, and the pixel defining layer 15 covers pixel electrode 161 and the second planarization layer 142.

[0076] The common electrode 163 can serve as the cathode, and the pixel electrode 161 can serve as the anode. Light emission from the light-emitting element 162 can be driven by applying a signal to the pixel electrode 161; the specific light emission principle will not be detailed here. The light-emitting element 162 may contain an electroluminescent organic light-emitting material and can be formed using processes such as vapor deposition. For example, the light-emitting element 162 may include a hole injection layer, a hole transport layer, a light generation layer, an electron transport layer, and an electron injection layer sequentially stacked on the pixel electrode 161 layer. It should be noted that the light-emitting element 162 may include a red light-emitting element 162, a green light-emitting element 162, and a blue light-emitting element 162, depending on the emitted color.

[0077] When the light-emitting unit 160 is a stacked light-emitting device, the light-emitting element 162 includes a common layer 1621 and two light-emitting layer groups 1622. The two light-emitting layer groups 1622 are respectively disposed on the side of the common layer 1621 near the substrate 11 and on the side of the common layer 1621 away from the substrate 11. To prevent crosstalk, a partition groove can be provided between two adjacent pixel openings 151 to isolate the common layer 1621 between the two adjacent pixel openings 151. The partition groove may include a first groove 253 and a first partition opening 152 sequentially disposed along the direction away from the substrate 11. The first groove 253 and the first partition opening 152 are interconnected. The first groove 253 is disposed on the second planarization layer 142, and the first partition opening 152 is disposed on the pixel defining layer 15. The orthographic projection of the first partition opening 152 on the substrate 11 can be arranged within the orthographic projection of the first groove 253 on the substrate 11.

[0078] As shown in the figure, the orthographic projection of the first groove 253 on the substrate 11 can also be located within the orthographic projection of the first isolation opening 152 on the substrate 11. In order to ensure effective isolation of the common layer 1621, the display panel can also include an isolation layer 25. The isolation layer 25 is located on the side of the second planarization layer 142 away from the substrate 11. The isolation layer 25 includes an anti-crosstalk isolation structure. The anti-crosstalk isolation structure includes multiple anti-crosstalk isolation portions 251. One anti-crosstalk isolation portion 251 can be provided to extend beyond the edge of the first groove 253, and the common layer 1621 is isolated at the edge of the anti-crosstalk isolation portion 251.

[0079] It should be noted that the partition layer 25 is generally made of inorganic insulating layer, and the material of the partition layer 25 includes at least one of silicon nitride, silicon oxynitride, and silicon oxide.

[0080] To ensure the isolation effect and avoid the situation where one anti-crosstalk isolation part 251 cannot effectively isolate the common layer, two anti-crosstalk isolation parts 251 can be provided between every two pixel openings 151. Both anti-crosstalk isolation parts 251 are provided to extend beyond the edge of the first groove 253, so that the orthographic projection of the second isolation opening formed between the two anti-crosstalk isolation parts 251 on the substrate 11 is located within the orthographic projection of the first groove on the substrate 11. The common layer is isolated by the two anti-crosstalk isolation parts 251, thus ensuring the isolation effect.

[0081] Furthermore, the display panel disclosed herein may also include an encapsulation layer 17, which is disposed on the side of the light-emitting layer 16 away from the substrate 11, thereby encapsulating the light-emitting layer 16 and preventing water and oxygen corrosion. The encapsulation layer 17 may be a single-layer or multi-layer structure, and the material of the encapsulation layer 17 may include organic or inorganic materials, without special limitations herein.

[0082] In this embodiment, the encapsulation layer 17 may include a first inorganic encapsulation layer 171, an organic encapsulation layer 172, and a second inorganic encapsulation layer 173. The first inorganic encapsulation layer 171 is disposed on the side of the light-emitting layer 16 away from the substrate 11, the organic encapsulation layer 172 is disposed on the side of the first inorganic encapsulation layer 171 away from the substrate 11, and the second inorganic encapsulation layer 173 is disposed on the side of the organic encapsulation layer 172 away from the substrate 11.

[0083] The display panel also includes a touch control layer 18, which can be a mutual capacitance touch control layer. The touch control layer 18 includes a first passivation layer 181, a first touch control layer 182, a second passivation layer 183, and a second touch control layer 184. The first passivation layer 181 is disposed on the side of the encapsulation layer 17 away from the substrate 1. The first touch control layer 182 is disposed on the side of the first passivation layer 181 away from the substrate 11. The second passivation layer 183 is disposed on the side of the first touch control layer 182 away from the substrate 11. The second touch control layer 184 is disposed on the side of the second passivation layer 183 away from the substrate 11. The second touch control layer 184 is disposed on the side of the second touch control layer 184 away from the substrate 11. A cover layer 19 is disposed on the side of the second touch control layer 184 away from the substrate 11.

[0084] The first touch control layer 182 may include an effective touch unit 1821, which may include a touch mesh layer 1822, which may be a metal mesh layer (MM). The second touch control layer 184 may be a touch bridging layer, which may be a bridge metal layer (BM). The first touch control layer 182 may also be a bridge metal layer (BM), and the second touch control layer 184 may be a metal mesh layer (MM).

[0085] As shown in Figure 2, in this embodiment, the display panel has an opening 300, and the non-display area 200 is located between the edge of the opening 300 and the edge of the display area 100. Because of the flow of liquid organic encapsulation material, leakage is likely. To prevent leakage, a barrier dam 20 is provided in the non-display area 200. The barrier dam 20 is located on the side of the protective layer 137 away from the substrate 11, and surrounds the opening 300. The barrier dam 20 serves to block the organic encapsulation material. The cross-sectional shape of the barrier dam 20 can be rectangular or trapezoidal, and the barrier dam 20 must have at least one beveled side near the display area 100; this is not limited here.

[0086] The stacked pattern of the barrier dam 20 is made of one or more layers of the same material as the first planarization layer 141, the second planarization layer 142, and the pixel defining layer 15. As shown in Figure 2, the stacked pattern of the barrier dam 20 includes a first insulating layer 201, which is made of the same material as the first planarization layer 141. A second insulating layer 202 can also be provided on the first insulating layer 201, which is made of the same material as the second planarization layer 142. A third insulating layer 203 can also be provided on the second insulating layer 202, which is made of the same material as the pixel defining layer 15.

[0087] The non-display area 200 includes a first sub-non-display area 2001 and a second sub-non-display area 2002. The first sub-non-display area 2001 is located between the edge of the barrier dam 20 near the opening 300 and the edge of the opening 300. The second sub-non-display area 2002 is located between the edge of the barrier dam 20 far away from the opening 300 and the edge of the display area 100. That is, the second sub-non-display area 2002 is set closer to the display area 100, and the first sub-non-display area 2001 is set farther away from the display area 100 than the second sub-non-display area 2002.

[0088] As shown in Figures 2 and 3, the partition layer 25 also includes a corrosion-resistant partition structure. This corrosion-resistant partition structure is located in the second sub-non-display area 2002. The corrosion-resistant partition structure includes multiple corrosion-resistant partition portions 252 spaced sequentially along a direction away from the display area 100, surrounding the opening 300. In the second sub-non-display area 2002, the common electrode 163 is separated by the step closest to the display area 100, forming a conductive portion 164 and a suspended portion 165. Between the corrosion-resistant partition portion 252 closest to the display area 100 and the edge of the display area 100, a second groove 254 is provided on the second planarization layer 142. The edge of the corrosion-resistant partition portion 252 and the bottom of the second groove 254 form a step, thus separating the common electrode 163 from the step closest to the display area 100, forming a conductive portion 164 and a suspended portion 165.

[0089] The anti-corrosion partition structure includes at least two anti-corrosion partition portions 252, which are spaced apart. The suspended portion 165 includes a first suspended portion 1651 and a second suspended portion 1652. The first suspended portion 1651 is located on the side of the anti-corrosion partition portion 252 away from the substrate 11. A second groove 254 is provided between two adjacent first suspended portions 1651, and the second suspended portion 1652 is located at the bottom of the second groove 254 between two adjacent first suspended portions 1651. Firstly, the width of the suspended portion 165 can be increased. Secondly, a drainage channel can be formed between two adjacent anti-corrosion partition portions 252, extending the intrusion path of water and oxygen. It should be noted that, to further ensure that the common electrode is isolated, the width of the second groove 254 can be gradually reduced along the direction away from the substrate 11.

[0090] The non-display area 200 is provided with a plurality of isolation units 21, which include a plurality of first isolation units 211 and a plurality of second isolation units 212. The plurality of first isolation units 211 are located in the first sub-non-display area 2001, and the plurality of second isolation units 212 are located in the second sub-non-display area 2002. The number of first isolation units 211 is greater than the number of second isolation units 212. The suspended portion 165 may further include a third suspended portion 1653, a fourth suspended portion 1654, and a fifth suspended portion 1655. The third suspended portion 1653 is located on the side of the isolation unit 21 away from the substrate 11, the fourth suspended portion 1654 is located between two adjacent isolation units 21, and the fifth suspended portion 1655 is located on the side of the barrier dam 20 away from the substrate 11.

[0091] As shown in Figure 4, the touch grid layer 1822 has multiple grids, and the orthographic projection of the light-emitting unit 160 on the substrate 11 is located within the area enclosed by the grids on the substrate 11. The touch grid layer 1822 extends from the display area 100 to the non-display area 200. The effective touch portion 1821 also includes an effective touch trace 1823, which is connected to the touch grid layer 1822 and is located between the barrier dam 20 and the touch grid layer 1822. The orthographic projection of the anti-corrosion barrier portion 252 on the substrate 11 overlaps with the orthographic projections of the touch grid layer 1822 and the effective touch trace 1823 on the substrate 11.

[0092] The orthographic projections of the touch grid layer 1822 and the effective touch trace 1823 on the substrate 11, the orthographic projection of the light-emitting control trace 24 on the substrate 11, and the orthographic projection of the anti-corrosion barrier 252 on the substrate 11 overlap with each other. In this case, the orthographic projection of the suspended portion 165 on the substrate 11 overlaps with the orthographic projections of the touch grid layer 1822 and the effective touch trace 1823 on the substrate 11, and the touch signal and the light-emitting control signal will interfere with each other.

[0093] As shown in Figure 5, the driving circuit layer 13 also includes a light-emitting control trace 24. The light-emitting control trace 24 is arranged around the opening 300 and is located in the first sub-non-display area 2001 between the barrier dam 20 and the display area 100. The light-emitting control trace 24 may include a data signal line 242 and a gate signal line 241. The orthographic projection of the light-emitting control trace 24 on the substrate 11 is located within the orthographic projection of the anti-corrosion partition 252 on the substrate 11.

[0094] To avoid crosstalk between the light-emitting control signal loaded on the light-emitting control trace 24 and the touch signal loaded on the effective touch portion 1821, the common electrode 163 extends between the light-emitting control trace 24 and the effective touch portion 1821 to shield the signal. Because the edge of the anti-corrosion partition 252 forms a step with the side of the second planarization layer 142 away from the substrate 11, the common electrode 163 is isolated at the step. The suspended portion 165 between the touch trace and the backplane trace has no shielding effect, resulting in crosstalk between the touch trace and the backplane trace, which can easily cause touch failure.

[0095] As shown in Figures 6 and 7, the isolation unit 21 can isolate the common electrode 163, so the anti-corrosion isolation structure can be removed, thereby avoiding the situation where the area where the orthographic projection of the common electrode 163 on the substrate 11 overlaps with the orthographic projection of the light-emitting control line 24 on the substrate 11 and the orthographic projection of the effective touch part 1821 on the substrate 11 is isolated, forming a suspended part 165, thus ensuring the stability of the touch signal.

[0096] As shown in Figure 8, the position of the edge of the anti-corrosion partition structure can also be adjusted. The anti-corrosion partition structure is located on the side of the light-emitting control line 24 away from the display area 100. The anti-corrosion partition part 252 closest to the display area 100 forms a step closest to the display area 100 with the planarization layer 14. The two sides of the step closest to the display area 100 are the first region 2003 and the second region 2004, respectively. The light-emitting control line 24 is located in the first region 2003.

[0097] After the common electrode 163 is isolated by the anti-corrosion barrier structure, the orthographic projection of the conductive part 164 on the substrate 11 is located in the first region 2003, and the orthographic projection of the suspended part 165 on the substrate 11 is located in the second region 2004. The orthographic projection of the conductive part 164 on the substrate 11 covers the orthographic projection of the light-emitting control trace 24 on the substrate 11, while the orthographic projection of the suspended part 165 on the substrate 11 does not overlap with the orthographic projection of the light-emitting control trace 24 on the substrate 11. While the conductive part 164 provides a shielding effect, the suspended part 165 remains de-energized, improving the anti-electro-corrosion effect of the non-display area 200 around the opening 300.

[0098] As shown in Figures 9 to 12, the anti-corrosion partition structure includes multiple anti-corrosion partition portions 252 spaced apart along the direction away from the hole 300. The orthographic projection of the touch grid layer 1822 on the substrate 11 overlaps with the orthographic projection of the anti-corrosion partition portion 252 closest to the display area 100 on the substrate 11. The orthographic projection of the effective touch trace 1823 on the substrate 11 overlaps with the orthographic projections of the two anti-corrosion partition portions 252 closest to the display area 100 on the substrate 11. The touch control layer 18 also includes a virtual touch trace 1824, which overlaps with the orthographic projection of the anti-corrosion partition portion 252 farthest from the display area 100 on the substrate 11.

[0099] The virtual touch trace 1824 is suspended, effectively shielding electromagnetic fields and preventing electromagnetic interference and radiation, thus maintaining the stability of the touch signal. Generally, a ring-shaped virtual touch trace 1824 provides better electromagnetic field shielding. Additionally, the virtual touch trace 1824 can also block diffuse reflections caused by unevenness in other underlying film layers (e.g., gate signal line 241 and data signal line 242), thus shielding light and preventing physical shine around the hole.

[0100] As shown in Figures 13 to 15, to prevent interference with the touch signal, the edge of the anti-corrosion barrier structure adjacent to the display area 100 is moved towards the opening 300, so that the edge of the anti-corrosion barrier structure adjacent to the display area 100 is located on the side of the effective touch trace 1823 near the opening 300. That is, the touch mesh layer 1822 is located within the display area 100 and the first region 2003, and the effective touch trace 1823 is located within the first region 2003. Therefore, the orthographic projection of the touch mesh layer 1822 on the substrate 11 and the orthographic projection of the effective touch trace 1823 on the substrate 11 do not overlap with the orthographic projection of the anti-corrosion barrier structure on the substrate 11.

[0101] When the common electrode 163 is separated by the edge of the anti-corrosion partition 252 closest to the display area 100, the orthographic projection of the conductive part 164 on the substrate 11 is located within the first region 2003 and the display area 100, and the orthographic projection of the suspended part 165 on the substrate 11 is located in the second region 2004. Therefore, the orthographic projection of the conductive part 164 on the substrate 11 can cover the orthographic projections of the touch grid layer 1822 and the effective touch trace 1823 on the substrate 11, and the conductive part 164 can prevent touch signals on the touch grid layer 1822 and the effective touch trace 1823 from being interfered with. The width of the effective touch trace 1823 can also be adjusted to increase the distance between the edge of the anti-corrosion partition 252 closest to the display area 100 and the effective touch trace 1823, further reducing the possibility of the orthographic projection of the suspended part 165 on the substrate 11 overlapping with the orthographic projection of the effective touch trace 1823 on the substrate 11.

[0102] Because the distance between the edge of the corrosion-resistant partition 252 closest to the display area 100 and the effective touch trace 1823 is increased, the number of virtual touch traces 1824 can be increased. The virtual touch traces 1824 are located on the side of the effective touch trace 1823 closest to the opening 300. The orthographic projection of the virtual touch trace 1824 on the substrate 11 at least partially overlaps with the orthographic projection of the corrosion-resistant partition structure on the substrate 11; that is, the virtual touch trace 1824 is partially located in the first region 2003 and partially in the second region 2004. The orthographic projection of the suspended portion 165 on the substrate 11 overlaps only with the orthographic projection of the virtual touch trace 1824 on the substrate 11. This prevents interference with the touch signal and further improves the stability of the touch signal.

[0103] A corrosion-resistant barrier structure can be set away from both the light-emitting control trace 24 and the effective touch portion 1821. As shown in Figure 16, the orthographic projection of the light-emitting control trace 24 on the substrate 11 and the orthographic projection of the effective touch portion 1821 on the substrate 11 overlap in the first region 2003, while the orthographic projection of the corrosion-resistant barrier structure on the substrate 11 does not overlap with the first region 2003. The corrosion-resistant barrier portion 252 closest to the display area 100 forms a step closest to the display area 100 with the planarization layer 14 near the edge of the display area 100. The common electrode 163 is isolated by the step closest to the display area 100, forming a conductive portion 164 and a suspended portion 165. The conductive portion 164 is located on the side of the planarization layer 14 away from the substrate 11, serving to shield the touch signal and the light-emitting control signal. The suspended portion 165 is located on the side of the corrosion-resistant barrier structure away from the substrate 11. The suspended portion 165 is non-conductive, which can enhance the anti-electrochemical corrosion effect around the opening 300.

[0104] As shown in Figure 17, the pixel definition layer extends to the side of the anti-corrosion barrier structure away from the substrate 11. The edge of the pixel definition layer and the side of the anti-corrosion barrier structure away from the substrate 11 form a step difference closest to the display area 100, so that the common electrode 163 is separated into a conductive part 164 and a suspended part 165. The conductive part 164 is located on the side of the pixel definition layer away from the substrate 11, and the suspended part 165 is located on the side of the anti-corrosion barrier structure away from the substrate 11. The conductive part 164 serves to shield the touch signal and the light emission control signal, while the suspended part 165 can enhance the anti-electro-corrosion effect around the opening 300. Typically, when depositing the light-emitting element 162, a support pillar layer is provided on the side of the pixel definition layer away from the substrate 11. The mask is supported by the support pillars of the support pillar layer. Therefore, the support pillar layer can also cover the side of the anti-corrosion barrier structure away from the substrate 11, forming a step difference with the side of the anti-corrosion barrier structure away from the substrate 11.

[0105] As shown in Figures 17 and 18, the anti-corrosion partition structure includes two anti-corrosion partition portions 252, which are spaced apart. As shown in Figure 17, the pixel definition layer can extend to the side of the anti-corrosion partition portion 252 closest to the display area 100 that is furthest from the substrate 11. As shown in Figure 18, the pixel definition layer can also cover the area of ​​the planarization layer 14 located between two adjacent anti-corrosion partition portions 252, and the pixel definition layer extends to the side of the anti-corrosion partition portion 252 furthest from the display area 100 that is furthest from the substrate 11. Therefore, the orthographic projection of the conductive portion 164 onto the substrate 11 covers the orthographic projection of the anti-corrosion partition portion 252 furthest from the display area 100 onto the substrate 11. Based on the figures, the width of the suspended portion 165 can be increased to extend the water and oxygen intrusion path, further enhancing the anti-water and oxygen corrosion effect around the opening 300.

[0106] As shown in Figures 19 to 21, when the width of the effective touch lines and light-emitting control lines 24 around the opening 300 projected onto the substrate 11 is relatively large, it may be necessary to set the width of the anti-corrosion partition 252 to be relatively large. This can lead to moisture release issues. The anti-corrosion partition 252 has a first opening 22 exposing the planarization layer 14. The pixel definition layer extends into the first opening 22, wrapping around the edge of the first opening 22 and covering the side of the planarization layer 14 away from the substrate 11. The edge of the pixel definition layer within the first opening 22 forms a second opening 23. The conductive part 164 is attached to the planarization layer 14 within the second opening 23. The conductive part 164 remains continuous within the second opening 23, allowing moisture release while still providing shielding for the touch signal and light-emitting control signal.

[0107] As shown in Figures 22 to 25, the anti-corrosion partition 252 may include a plurality of anti-corrosion partition strips 2521, which are spaced apart along the direction away from the hole 300. Each anti-corrosion partition strip 2521 includes at least two sub-anti-corrosion partition strips 2522 that are broken along its length. The conductive part 164 is divided into a plurality of conductive strips 166 and a plurality of connecting parts 167 by the plurality of sub-anti-corrosion partition strips 2522. Two adjacent conductive strips 166 are connected together by the connecting parts 167. The orthographic projection of the conductive strips 166 on the substrate 11 is located between the orthographic projections of two adjacent anti-corrosion partition strips 2521 on the substrate 11. The orthographic projection of the connecting parts 167 on the substrate 11 is located within the orthographic projection of the discontinuity 2523 between two adjacent sub-anti-corrosion partition strips 2522 on the substrate 11.

[0108] The conductive part 164 is always energized, which can shield the touch signal and the light control signal. The suspended part 165 is kept de-energized, which enhances the anti-electrolytic corrosion effect around the opening 300. Every two adjacent anti-corrosion partitions 2521 can form a drainage channel, which can greatly extend the path of water and oxygen into the display area 100 and enhance the anti-water and oxygen corrosion effect around the opening 300.

[0109] The display panel has an opening 300, and at least some of the connecting portions 167 are offset along the extension direction of the opening 300. The angle between the line connecting any two adjacent connecting portions 167 and the center of the opening 300 is less than or equal to 180 degrees. In this way, the length of each drainage channel is around the opening 300, and each drainage channel is the longest possible. Therefore, the corrosion-resistant partition 252 of this structure can maximize the path for water and oxygen to enter the display area 100.

[0110] As shown in Figure 24, multiple connecting parts 167 are divided into multiple groups, and the multiple groups of connecting parts 167 are arranged sequentially along the direction away from the hole 300. The included angle α between the line connecting two adjacent connecting parts 167 in each group and the center O of the hole 300 is greater than or equal to 10 degrees and less than or equal to 30 degrees. Two adjacent connecting parts 167 are located on the same straight line along the direction away from the hole 300, and the distance between two adjacent connecting parts 167 on the same straight line is equal. Two adjacent conductive strips 166 form annular discontinuities 2523. The staggered distance on the annular discontinuities 2523 of two adjacent connecting parts 167 is relatively appropriate. While water and oxygen are drained through multiple drainage channels, the resistance of the entire common electrode 163 will not be too high. This avoids the situation where the voltage at the corresponding position of the common electrode 163 cannot reach the voltage required to shield the signal when a touch signal is input, thus ensuring a good shielding effect.

[0111] The orthographic projection of the light-emitting control trace 24 on the substrate 11 lies between the orthographic projections of the two adjacent anti-corrosion partition strips 2521 on the substrate 11, and the orthographic projection of the conductive strip 166 on the substrate 11 covers the orthographic projection of the light-emitting control trace 24 on the substrate 11. In this way, the light-emitting control signals on each light-emitting control trace 24 are shielded by the corresponding conductive strip 166 when they transition. By extending the path for water and oxygen to enter the display area 100, the corrosion resistance around the opening 300 is enhanced, while simultaneously improving the signal shielding effect of the conductive part 164.

[0112] The orthographic projection of the effective touch portion 1821 on the substrate 11 does not overlap with the orthographic projection of the light-emitting control trace 24 on the substrate 11. The orthographic projection of the conductive portion 164 on the substrate 11 may overlap with the orthographic projection of the light-emitting control trace 24 on the substrate 11, or the orthographic projection of the conductive portion 164 on the substrate 11 and the orthographic projection of the effective touch portion 1821 on the substrate 11 may be in the first region 2003. The light-emitting control trace 24 and the touch signal line are staggered in the width direction of the aperture 300, which can further reduce the possibility of mutual interference between the touch signal and the light-emitting control signal.

[0113] It should be noted that the width direction of the opening 300 mentioned above refers to the direction of the line connecting the center and the edge of the opening 300. Taking a circular opening 300 as an example, the width direction of the opening 300 is the radial direction of the circular opening 300.

[0114] This invention also provides a display panel. As shown in FIG26, the display panel has a display area 100 and a non-display area 200 arranged adjacently. The non-display area 200 is adjacent to the outside. The display panel includes a driving backplate, a plurality of anti-corrosion partition strips 2521, a common electrode 163, and a touch control layer 18. The driving backplate includes a substrate 11 and light-emitting control lines 24, with the light-emitting control lines 24 disposed on one side of the substrate 11. The plurality of anti-corrosion partition strips 2521 are disposed on the side of the light-emitting control lines 24 away from the substrate 11, and the plurality of anti-corrosion partition strips 2521 are located in the non-display area 200. Multiple anti-corrosion partition strips 2521 are spaced apart along a direction away from the display area 100. Each anti-corrosion partition strip 2521 includes at least two sub-anti-corrosion partition strips 2522 that are broken along its length. A common electrode 163 is located on the side of the insulating layer group away from the driving backplate. The common electrode 163 is divided into multiple conductive strips 166 and multiple connecting portions 167 by the multiple anti-corrosion partition strips 2521. The multiple conductive strips 166 are spaced apart, and two adjacent conductive strips 166 are connected together by the connecting portions 167. A touch control layer 18 is located on the side of the common electrode 163 away from the substrate 11. The touch control layer 18 includes an effective touch portion 1821. The edge of the orthographic projection of the common electrode 163 on the substrate 11 is farther from the edge of the display area 100 than the edge of the orthographic projection of the light-emitting control line 24 on the substrate 11 and / or the edge of the orthographic projection of the effective touch portion 1821 on the substrate 11.

[0115] Two adjacent conductive strips 166 are connected together by a connecting part 167. The common electrode 163 is always energized. The edge of the orthographic projection of the common electrode 163 on the substrate 11 is farther from the edge of the display area 100 than the edge of the orthographic projection of the light-emitting control line 24 on the substrate 11 and / or the edge of the orthographic projection of the effective touch part 1821 on the substrate 11. Therefore, the shielding area of ​​the common electrode 163 can cover the light-emitting control line 24 and / or the effective touch part 1821, which can shield the touch signal and the light-emitting control signal. Each pair of adjacent anti-corrosion partition strips 2521 can form a drainage channel, which can greatly extend the path of water and oxygen into the display area 100 and enhance the anti-water and oxygen corrosion effect around the opening 300.

[0116] The orthographic projection of the light-emitting control trace 24 on the substrate 11 lies between the orthographic projections of the two adjacent anti-corrosion partition strips 2521 on the substrate 11, and the orthographic projection of the conductive strip 166 on the substrate 11 covers the orthographic projection of the light-emitting control trace 24 on the substrate 11. In this way, when the light-emitting control signal on each light-emitting control trace 24 changes, it is shielded by the corresponding conductive strip 166, which can further reduce the possibility of mutual interference between the touch signal and the light-emitting control signal.

[0117] In other feasible embodiments, for a framed display panel, when the water and oxygen isolation effect in the outer area is poor, the non-display area 200 can also be located in the frame area away from the display area 100. The common electrode 163 extending to the frame area can be isolated by the anti-corrosion isolation structure, or the water and oxygen entry path can be extended by the drainage channel between adjacent anti-corrosion isolation parts 252, thereby improving the ability of the frame area to resist water and oxygen corrosion.
