[0052] In recent years, OLED (Organic Light-Emitting Diode) has attracted widespread attention due to its huge application market in the display field. Compared with other display technologies, OLED modules have many advantages, such as wide viewing angle, fast response speed, no need for backlighting, and flexible display.

[0053] The display panel in the related art is provided with a touch electrode to realize the touch function of the display panel. However, the touch electrode blocks the light output of the sub-pixel, thereby affecting the display effect. The touch electrode in the related art is usually a mesh electrode structure, and the mesh electrode structure includes electrode lines. Although the problem of blocking the light output of the light-emitting element can be improved by reducing the width of the electrode line, the electrode line must also meet the impedance requirements, so the width of the electrode line cannot be lower than the minimum design value. In this context, there is a need for a better solution to improve the blocking problem.

[0054] In view of the above problems, an embodiment of the first aspect of the present application proposes a display panel, which aims to solve the problem that the touch electrode may block the light output of the sub-pixel.

[0055] like Figure 1 , Figure 2 as well as Figure 3 As shown, the display panel 10 in the embodiment of the first aspect of the present application includes a display substrate 100 and a touch electrode 200, wherein the touch electrode 200 is disposed on one side of the display substrate 100, and the touch electrode 200 includes an electrode line 210. The electrode line 210 includes a main body 211 and an auxiliary conductive part 212 electrically connected to the main body 211, and the visible light transmittance of the auxiliary conductive part 212 is greater than the visible light transmittance of the main body 211. The auxiliary conductive part 212 is disposed on at least one side of the main body 211 along a first direction, and the first direction intersects with the thickness direction of the display substrate 100.

[0056] It can be understood that the extending direction of the orthographic projection of the electrode line 210 on the display substrate 100 is regarded as the length direction of the orthographic projection, and thus the direction perpendicular to the length direction is the width direction of the orthographic projection.

[0057] Specifically, the display panel 10 may be an OLED display panel 10, which includes a display substrate 100 and a touch electrode 200, wherein the touch electrode 200 is used to implement the touch function of the display panel 10. The touch electrode 200 may be a touch driving electrode or a touch sensing electrode. The touch electrode 200 is a mesh electrode or other shapes, and the touch electrode 200 includes an electrode line 210.

[0058] In the display panel 10 in the embodiment of the present application, the touch electrode 200 includes an electrode line 210, and the number of the electrode line 210 is not limited, and can be one or more. The electrode line 210 includes a main body 211 and an auxiliary conductive part 212 electrically connected to the main body 211, and the auxiliary conductive part 212 is arranged on at least one side of the main body 211 along the first direction, and the visible light transmittance of the auxiliary conductive part 212 is greater than the visible light transmittance of the main body 211. The light output of the sub-pixel in the display panel 10 can at least pass through the auxiliary conductive part 212, so that the shielding of the light output of the sub-pixel by the touch electrode 200 can be reduced. On the other hand, since the auxiliary conductive part 212 is provided in the electrode line 210, it is beneficial to keep the electrode line 210 at a certain width, so that the electrode line 210 is beneficial to meet the impedance requirements. Therefore, the display panel 10 in the embodiment of the present application can meet the impedance requirements of the electrode line 210 and improve the shielding problem of the touch electrode 200 on the sub-pixel light output by improving the structure of the electrode line 210.

[0059] In some embodiments, the material of the main body 211 includes metal, and the visible light transmittance of the auxiliary conductive part 212 is greater than 80%. In the related art, the electrode line 210 of the touch electrode 200 is usually made of metal. In this embodiment, the material of the main body 211 includes metal, that is, the main body 211 can be consistent with the material of the existing structure, which is conducive to maintaining the original physical properties of the electrode line 210. In addition, the visible light transmittance of the auxiliary electrode part is greater than 80%, so that most of the light output of the sub-pixel can be emitted through the auxiliary electrode part, thereby significantly improving the problem of the touch electrode 200 blocking the sub-pixel light output.

[0060] Furthermore, the material of the auxiliary conductive portion 212 includes metal oxide. It is understandable that the auxiliary electrode portion can be a metal oxide with high visible light transmittance (such as a transparent metal oxide).

[0061] Exemplarily, the material of the auxiliary conductive part 212 may include at least one of indium tin oxide, indium zinc oxide, and indium tin zinc oxide. Indium tin oxide, indium zinc oxide, and indium tin zinc oxide are all metal oxides with high transmittance (usually above 85%) and good conductivity, so they can better meet the use requirements of the auxiliary conductive part 212.

[0062] In some embodiments, Figure 4 As shown, the main body 211 includes a first metal layer 2111, a second metal layer 2112 and a third metal layer 2113 which are stacked. The materials of the first metal layer 2111 and the third metal layer 2113 are titanium, and the material of the second metal layer 2112 is aluminum. Aluminum has a relatively low resistivity, which is beneficial for reducing power consumption during signal transmission. However, aluminum also has the problem of being easily diffused when in contact with other metal oxides. Therefore, the material of the first metal layer 2111 and the third metal layer 2113 is titanium with good contact characteristics, thereby optimizing impedance and preventing aluminum from diffusing.

[0063] Furthermore, the second metal layer 2112 is arranged on the side of the first metal layer 2111 away from the display substrate 100, and the third metal layer 2113 is arranged on the side of the second metal layer 2112 away from the first metal layer 2111, so that the main body 211 presents a three-layer metal structure similar to a "sandwich" along the thickness direction of the display substrate 100.

[0064] In some embodiments, the main body 211 includes at least two sub-parts arranged along the first direction, and different sub-parts are made of different materials. In other words, the main body 211 can be composed of multiple sub-parts of different materials along the first direction.

[0065] For example, in one example, the main body 211 includes a first sub-section and a second sub-section arranged along a first direction, wherein the material of the first sub-section is aluminum, and the material of the second sub-section is molybdenum. For another example, the main body 211 includes a first sub-section, a second sub-section, and a third sub-section arranged in sequence along the first direction, wherein the material of the first sub-section is molybdenum or titanium, the material of the second sub-section is aluminum, and the material of the third sub-section is molybdenum or titanium. Such a configuration can ensure that the main body 211 has a lower resistivity and can also prevent the problem of diffusion of the resistivity when it contacts the auxiliary conductive portion 212.

[0066] In some embodiments, Figure 1 As shown, auxiliary conductive portions 212 are provided on both sides of the main body 211 along the first direction, which is beneficial to keep the influence of the electrode line 210 on the light output of the sub-pixels located on different sides of the electrode line 210 consistent, thereby facilitating improving the uniformity of display brightness at different positions of the display panel 10.

[0067] Furthermore, the widths of the two auxiliary conductive parts 212 located on both sides of the main body 211 along the first direction are equal. This arrangement can make the electrode line 210 have a more consistent effect on the light output of the sub-pixels located on different sides of the electrode line 210, thereby further improving the uniformity of the display brightness at different positions of the display panel 10.

[0068] Furthermore, a width H2 of an orthographic projection of the auxiliary conductive portion 212 on the display substrate 100 and a width H1 of an orthographic projection of the main body portion 211 on the display substrate 100 satisfy the following condition: H2 ≥ 1 / 2 H1.

[0069] On the basis that auxiliary conductive parts 212 are provided on both sides of the main body 211 along the first direction, and the widths of the two auxiliary conductive parts 212 on both sides of the main body 211 along the first direction are equal, H2≥1 / 2H1 is further set, so that the sum of the widths of the auxiliary conductive parts 212 on both sides is greater than or equal to the width of the main body 211, that is, the width of the light-transmitting part of the electrode line 210 accounts for more than half. Such a setting can further reduce the shielding of the main body 211 of the electrode line 210 on the light output of the sub-pixel, which is conducive to further improving the shielding problem of the touch electrode 200 on the light output of the sub-pixel.

[0070] In one embodiment, Figures 5 to 7 As shown, the two auxiliary conductive parts 212 and the main body 211 share the same film layer. Figure 8 As shown, one of the auxiliary conductive parts 212 shares the same film layer with the main body 211. In another embodiment, the two auxiliary electrode parts 212 may share the same film layer, and the main body 211 is located in another film layer. In other words, there may be many situations for the relative film layer relationship between the two conductive parts 212 and the main body 211, all of which are within the protection scope of this application.

[0071] In some embodiments, the auxiliary conductive portion 212 and the main body 211 are in direct contact with each other, thereby enabling the auxiliary conductive portion 212 and the main body 211 to be electrically connected, thereby facilitating the electrode line 210 to meet impedance requirements.

[0072] In one embodiment, the orthographic projection of the auxiliary conductive portion 212 on the display substrate 100 is connected to the orthographic projection of the main body portion 211 on the display substrate 100 without overlapping. In other words, the side surface of the auxiliary conductive portion 212 and the side surface of the main body portion 211 are in contact with each other, so that the auxiliary conductive portion 212 and the main body portion 211 are electrically connected.

[0073] Specifically, Figure 5 As shown, the auxiliary conductive part 212 and the main body 211 are in contact with each other, and the orthographic projection of the auxiliary conductive part 212 on the display substrate 100 has no overlapping area with the orthographic projection of the main body 211 on the display substrate 100. It can be further set that the top surface of the main body 211 on the side away from the display substrate 100 is flush with the top surface of the auxiliary conductive part 212 on the side away from the display substrate 100. In this way, the top surface of the electrode line 210 on the side away from the display substrate 100 has a good flatness.

[0074] In another embodiment, the orthographic projection of the auxiliary conductive portion 212 on the display substrate 100 and the orthographic projection of the main body portion 211 on the display substrate 100 have an overlapping area. Figure 6 As shown, a first extension portion 213 extending from both sides along the first direction may be provided on the main body portion 211, and the first extension portion 213 at least partially covers the surface of the auxiliary conductive portion 212 away from the display substrate 100. Figure 7 As shown, a second extension portion 214 extending along the first direction toward the main body portion 211 may also be provided on the auxiliary conductive portion 212, and the second extension portion 214 at least partially covers the surface of the main body portion 211 on the side away from the display substrate 100. Such a configuration is conducive to improving the contact stability between the auxiliary conductive portion 212 and the main body portion 211, so that a stable electrical connection relationship is maintained between the two.

[0075] In some embodiments, Figure 2 , Figure 3 As shown, the display substrate 100 includes a substrate 110 and a plurality of sub-pixel units 120 spaced apart on the substrate 110 , each sub-pixel unit 120 includes a light-emitting functional portion 121 , and the orthographic projection of the light-emitting functional portion 121 on the substrate 110 has no overlapping area with the orthographic projection of the main body portion 211 on the substrate 110 .

[0076] Specifically, the substrate 110 may include a substrate and a driving circuit disposed on the substrate. The substrate may be a rigid substrate or a flexible substrate. When the substrate is a rigid substrate, the material of the substrate may be glass or silicon wafer, etc. When the substrate is a flexible substrate, the material of the substrate may be metal foil, polymer plastic, etc.

[0077] The sub-pixel unit 120 includes a light-emitting functional unit 121, which may specifically include an organic light-emitting layer of an OLED light-emitting element. In addition, the light-emitting functional unit 121 may also include light-emitting auxiliary layers such as a hole injection layer, a hole transport layer, an electron transport layer and an electron injection layer.

[0078] In this embodiment, the orthographic projection of the light-emitting functional portion 121 on the substrate 110 has no overlapping area with the orthographic projection of the main body portion 211 on the substrate 110. This helps to avoid the main body portion 211 of the electrode line 210 from blocking the light output of the light-emitting functional portion 121, thereby helping to improve the light output efficiency of the display panel 10.

[0079] In some embodiments, the display panel 10 further includes a partition structure 140 , which partitions the light-emitting functional parts 121 of adjacent sub-pixel units 120 , and the orthographic projection of the electrode line 210 on the substrate 110 is located within the orthographic projection of the partition structure 140 on the substrate 110 .

[0080] Specifically, a plurality of first openings 145 may be defined on the partition structure 140 , and the light-emitting functional parts 121 of the plurality of sub-pixel units 120 may be disposed in the plurality of first openings 145 in a one-to-one correspondence, so that the light-emitting functional parts 121 of different sub-pixel units 120 may be isolated by the partition structure 140 .

[0081] In this embodiment, the orthographic projection of the main body 211 on the substrate 110 is located within the orthographic projection of the partition structure 140 on the substrate 110. Therefore, it can be ensured that in the thickness direction of the display panel 10, the main body 211 of the electrode line 210 and the light-emitting functional part 121 are staggered with each other, and there is no overlapping part in the orthographic projections of the two on the substrate 110. Such a setting is conducive to avoiding the main body 211 from blocking the light output of the sub-pixel unit 120, so as to improve the light output efficiency of the display panel 10.

[0082] In some embodiments, Figure 3 As shown, the sub-pixel unit 120 further includes a first electrode 122 and a second electrode 123, the light-emitting functional portion 121 is located on the side of the first electrode 122 away from the substrate 110, and the second electrode 123 is located on the side of the light-emitting functional portion 121 away from the substrate 110; the display panel 10 further includes a pixel definition layer 160, and the pixel definition layer 160 is provided with a plurality of pixel openings 161 for exposing the first electrode 122, and at least part of the light-emitting functional portion 121 is located in the pixel opening 161. The orthographic projection of the electrode line 210 on the substrate 110 and the orthographic projection of the pixel opening 161 on the substrate 110 do not overlap, and are staggered.

[0083] Specifically, the first electrode 122 is the anode of the OLED light-emitting element, and the second electrode 123 is the cathode of the OLED light-emitting element. The pixel definition layer 160 is provided with a pixel opening 161, and at least part of the light-emitting functional part 121 is located in the pixel opening 161, so that the light-emitting functional part 121 is electrically connected to the first electrode 122 through the pixel opening 161.

[0084] In this embodiment, the orthographic projection of the main body 211 on the substrate 110 has no overlapping area with the orthographic projection of the pixel opening 161 on the substrate 110 , thereby helping to avoid the electrode line 210 blocking the light output of the light-emitting functional part 121 , thereby helping to improve the light output efficiency of the display panel 10 .

[0085] In some embodiments, Figure 3 As shown, the display panel 10 further includes an encapsulation layer 170 . The encapsulation layer 170 is disposed on one side of the display substrate 100 , and the touch electrode 200 is disposed on a side of the encapsulation layer 170 away from the display substrate 100 .

[0086] Specifically, the encapsulation layer 170 may include a first encapsulation layer 171, a second encapsulation layer 172, and a third encapsulation layer 173, wherein the first encapsulation layer 171 includes a plurality of encapsulation parts 1711 arranged at intervals, each encapsulation part 1711 is configured to encapsulate the light-emitting functional part 121 of a sub-pixel unit 120, that is, the encapsulation part 1711 independently encapsulates the light-emitting functional part 121. The second encapsulation layer 172 is arranged on the side of the first encapsulation layer 171 away from the second encapsulation layer 172, and the third encapsulation layer 173 is arranged on the side of the second encapsulation layer 172 away from the first encapsulation layer 171. The encapsulation part 171 in the first encapsulation layer 171 independently encapsulates the light-emitting functional part 121 of the sub-pixel unit 120, and on this basis, the second encapsulation layer 172 and the third encapsulation layer 173 may be a whole-layer encapsulation. By arranging the first encapsulation layer 171, the second encapsulation layer 172, and the third encapsulation layer 173, multi-layer encapsulation can be achieved, which is conducive to improving the encapsulation performance of the encapsulation layer 170 in isolating water and oxygen.

[0087] Furthermore, the first encapsulation layer 171 and the third encapsulation layer 173 are inorganic encapsulation layers, and the second encapsulation layer 172 is an organic encapsulation layer.

[0088] In some embodiments, the partition structure 140 includes an insulator 141 and a blocking portion 142, the blocking portion 142 is arranged on the side of the insulator 141 facing away from the substrate 110, and the orthographic projection of the insulator 141 on the substrate 110 is located within the orthographic projection of the blocking portion 142 on the substrate 110; the visible light transmittance of the blocking portion 142 is greater than the visible light transmittance of the main body 211.

[0089] Specifically, the partition structure 140 includes an insulator 141 and a blocking portion 142. The blocking portion 142 is arranged on the side of the insulator 141 facing away from the substrate 110. The orthographic projection of the insulator 141 on the substrate 110 is located within the orthographic projection of the blocking portion 142 on the substrate 110, which forms a step structure between the bottom surface edge of the blocking portion 142 and the top surface edge of the insulator 141. The setting of the step structure is conducive to isolating the light-emitting functional portions 121 located on different sides of the partition structure 140 from each other.

[0090] In this embodiment, the visible light transmittance of the blocking portion 142 is greater than that of the main body 211 , thereby helping to reduce or avoid the blocking portion 142 from blocking the light output of the light-emitting functional portion 121 , thereby helping to further improve the light output efficiency of the display panel 10 .

[0091] Furthermore, the visible light transmittance of the barrier 142 is greater than or equal to 80%, so that most of the light emitted by the sub-pixel can be emitted through the barrier 142. The material of the barrier 142 can be, for example, indium tin oxide, indium zinc oxide, indium tin zinc oxide, silicon oxide, etc.

[0092] The embodiment of the first aspect of the present application provides a display device 1, including the display panel 10 in any embodiment of the first aspect. The display device 1 can be, for example, a display, a television, a digital camera, a mobile phone, a tablet computer, a navigator, or any other product or component with a display function.

[0093] In the display device 1 in the embodiment of the present application, the touch electrode 200 in the display panel 10 includes a plurality of electrode lines 210, and the electrode line 210 includes a main body 211 and an auxiliary conductive part 212 electrically connected to the main body 211, and the auxiliary conductive part 212 is arranged on at least one side of the main body 211 along the first direction, and the visible light transmittance of the auxiliary conductive part 212 is greater than the visible light transmittance of the main body 211. The light output of the sub-pixel in the display panel 10 can at least pass through the auxiliary conductive part 212, so that the shielding of the light output of the sub-pixel by the touch electrode 200 can be reduced. On the other hand, since the auxiliary conductive part 212 is provided in the electrode line 210, it is beneficial to keep a certain width of the electrode line 210, so that the electrode line 210 is beneficial to meet the impedance requirements. Therefore, the display panel 10 in the embodiment of the present application can meet the impedance requirements of the electrode line 210 and improve the shielding problem of the touch electrode 200 on the light output of the sub-pixel by improving the structure of the electrode line 210.
