[0057] Although exemplary embodiments of display modules and display devices including display modules have been specifically described herein, many modifications and variations will be apparent to those skilled in the art. Therefore, it will be understood that display modules and display devices including display modules constructed according to the principles of the present application may be implemented in addition to those specifically described herein. The present application is also defined in the claims and their equivalents.

[0058] As described in the background art, the display effect of the OLED display panel in the prior art needs to be improved. The inventors have found through research that the reason for this problem is that the potential uniformity of the initialization signal on the relevant initialization signal line needs to be improved.

[0059] Based on the above reasons, Figures 1 to 3 As shown, the present application provides a display panel, which includes: a substrate 11, a driving circuit layer 12 and an anode conductive layer 13. The substrate 11 may include a rigid substrate 11 such as glass, metal foil, etc., or may include a flexible substrate 11 made of similar materials such as polyimide (PI), polycarbonate (PC), polystyrene (PS), polyethylene (PE), polyvinyl chloride (PV), polyvinyl pyrrolidone (PVP), polyethylene terephthalate (PET), etc. The substrate 11 mainly plays a supporting role.

[0060] The driving circuit layer 12 is located on one side of the substrate 11; wherein the driving circuit layer 12 includes a plurality of first initialization signal lines 121, each of which is arranged along a first direction and extends along a second direction, and the first direction intersects the second direction. Figure 2 and Figure 3 As shown, the first direction may be the X-axis direction, and the second direction may be the Y-axis direction.

[0061] The anode conductive layer 13 is located on a side of the driving circuit layer 12 away from the substrate 11, and includes a plurality of first jumper wires 131. The first jumper wires 131 are used to connect two first initialization signal lines 121 adjacent to each other in a first direction.

[0062] After long-term research, the inventor found that in the related art, the first initialization signal line 121 is used to transmit the initialization signal. Since the first initialization signal line 121 has a resistor, the initialization signal of the first initialization signal line 121 will have a voltage drop during the transmission of the initialization signal, resulting in uneven initialization signal voltages at different positions, which in turn affects the display uniformity of the display panel. The anode conductive layer 13 is a conductive layer used to form a light-emitting element, which can drive the light-emitting element to emit light by receiving a driving current from a pixel circuit.

[0063] In this embodiment, the anode conductive layer 13 includes a plurality of first jumper wires 131, which are arranged in the first direction and the second direction at the same time, and are used to connect two adjacent first initialization signal lines 121 in the first direction, and then connect with the first initialization signal line 121 through the first jumper wire 131, so as to form a mesh parallel structure, and the overall resistance of the mesh parallel structure is less than the resistance of the first initialization signal line 121, so as to reduce the voltage drop on the first initialization signal line 121, improve the voltage uniformity on each first initialization signal line 121, thereby improving the uniformity of the initialization signal, and then improving the display uniformity of the display panel. In addition, since the first jumper wire 131 is located in the anode conductive layer 13, the first jumper wire 131 does not need to occupy the routing space of the drive circuit layer 12, so as to help reduce the number of conductive layers in the drive circuit layer 12, and then the conductive layer data of the display panel can be reduced, which is conducive to reducing the manufacturing cost of the display panel.

[0064] Exemplarily, the anode conductive layer 13 also includes a plurality of anode structures 132, and the anode structures 132 and the first jumper wires 131 are arranged at intervals. Among them, the anode structure 132 is the anode of the light-emitting element, and the anode conductive layer 13 is used to form the anode structure 132 of the light-emitting element, and the anode structure 132 can drive the light-emitting element to emit light by receiving the driving current of the pixel circuit. The anode structure 132 and the first jumper wire 131 are arranged at intervals, and the anode structure 132 and the first jumper wire 131 can be effectively arranged on the anode conductive layer 13 at the same time to realize their respective basic functions and reasonably arrange the wiring space.

[0065] The above-mentioned display panel includes a substrate 11 and a driving circuit layer 12 and an anode conductive layer 13 which are sequentially away from the substrate 11; two adjacent first initialization signal lines 121 are connected through a first jumper line 131, so that the first jumper line 131 and the first initialization signal line 121 form a mesh parallel structure, and the overall resistance of the mesh parallel structure is less than the resistance of the first initialization signal line 121, which can reduce the voltage drop on the first initialization signal line 121, improve the voltage uniformity of the initialization signal on each first initialization signal line 121, and thus improve the display effect of the display panel. Moreover, since the first jumper line 131 is located in the anode conductive layer 13, the first jumper line 131 does not need to occupy the routing space of the driving circuit layer 12, which is conducive to reducing the number of conductive layers in the driving circuit layer 12 and reducing the manufacturing cost of the display panel.

[0066] In one embodiment, the first initialization signal line 121 is used to transmit an anode initialization signal for resetting the anode voltage of the light emitting element.

[0067] In the application, the luminous brightness of the light-emitting element at a low gray scale is related to the anode voltage of the light-emitting element. Therefore, it is necessary to initialize the anode voltage of the light-emitting element through the anode initialization signal to improve the uniformity of the anode voltage of each light-emitting element, thereby improving the display uniformity of the display panel. On this basis, it can be understood that the anode voltage of each light-emitting element is related to the voltage of the corresponding anode initialization signal received. Therefore, the uniformity of the voltage of each anode initialization signal will affect the uniformity of the anode voltage of each light-emitting element. Corresponding to the aforementioned embodiment, by connecting the first jumper wire 131 to two adjacent first initialization signal lines 121 in the first direction, the first jumper wire 131 and the first initialization signal line 121 can form a mesh parallel structure, and the overall resistance of the mesh parallel structure is less than the resistance of the first initialization signal line 121, thereby reducing the voltage drop on the first initialization signal line 121, improving the uniformity of the anode initialization signal on each first initialization signal line 121, and improving the uniformity of the anode voltage of each light-emitting element, thereby improving the display uniformity of the display panel.

[0068] In another embodiment, the driving circuit layer 12 further includes a plurality of pixel circuits, and the first initialization signal line 121 further transmits a gate initialization signal for resetting the gate voltage of the driving transistor in the pixel circuit.

[0069] Among them, the pixel circuit is used to drive the light-emitting element to emit light, and the driving transistor is used to provide a light-emitting current to the light-emitting element during the light-emitting stage. The light-emitting brightness of the light-emitting element is related to the gate voltage of the driving transistor. Therefore, the gate initialization signal will also affect the light-emitting brightness of the light-emitting element. The uniformity of each gate initialization signal voltage will affect the display uniformity of the display panel.

[0070] It can be understood that, corresponding to the aforementioned embodiment, by connecting the first jumper line 131 to two adjacent first initialization signal lines 121 in the first direction, the first jumper line 131 and the first initialization signal line 121 can form a mesh parallel structure, and the overall resistance of the mesh parallel structure is less than the resistance of the first initialization signal line 121, thereby reducing the voltage drop on the first initialization signal line 121, improving the uniformity of the gate initialization signal on each first initialization signal line 121, and thereby improving the display uniformity of the display panel.

[0071] In yet another embodiment, Figure 2 As shown, the driving circuit layer 12 further includes a plurality of second initialization signal lines 122 and a plurality of pixel circuits. Each second initialization signal line 122 is arranged along the first direction and extends along the second direction.

[0072] The first initialization signal line 121 is used to transmit an anode initialization signal for resetting the anode voltage of the light-emitting element, and the second initialization signal line 122 is used to transmit a gate initialization signal for resetting the gate voltage of the driving transistor in the pixel circuit.

[0073] As described in the above embodiments, the luminous brightness of the light-emitting element is respectively related to the gate voltage of the driving transistor and the anode voltage of the light-emitting element. It can be understood that the anode voltage of the light-emitting element is reset by transmitting the anode initialization signal to the anode voltage of the light-emitting element through the first initialization signal line 121, and the gate initialization signal is transmitted to the gate of the driving transistor by the second initialization signal line 122 to reset the gate voltage of the driving transistor, thereby improving the uniformity of the luminous brightness of each light-emitting element to improve the display uniformity. In addition, since the first jumper line 131 and the first initialization signal line 121 form a mesh parallel structure, and the overall resistance of the mesh parallel structure is less than the resistance of the first initialization signal line 121, the voltage drop on the first initialization signal line 121 can be reduced, and the voltage uniformity on each first initialization signal line 121 can be improved, thereby improving the uniformity of the initialization signal and enhancing the display effect of the display panel.

[0074] In one embodiment, Figure 2 As shown, the second initialization signal line 122 is located between two adjacent first initialization signal lines 121 .

[0075] The second initialization signal line 122 is located between two adjacent first initialization signal lines 121 , that is, the first initialization signal lines 121 and the second initialization signal lines 122 are arranged alternately.

[0076] It can be understood that, through the above arrangement, the first initialization signal line 121 and the second initialization signal line 122 can be evenly distributed on the display panel, and the first initialization signal line 121 transmits an anode initialization signal to the anode of the light-emitting element, and correspondingly, the second initialization signal line 122 can transmit a gate initialization signal to the pixel circuit driving the light-emitting element. Therefore, each first initialization signal line 121 can transmit an anode initialization signal to the anode of the light-emitting element, and each second initialization signal line 122 can transmit a gate initialization signal to each pixel circuit corresponding to each light-emitting element, thereby improving the uniformity of the light-emitting brightness of each light-emitting element, so as to improve the display uniformity of the display panel.

[0077] In one embodiment, the anode conductive layer 13 further includes a plurality of second jumper wires (not shown in the figure), which are spaced apart from the anode structure 132 and the first jumper wire 131 , and are used to connect two second initialization signal lines 122 adjacent to each other in the first direction.

[0078] It can be understood that the second jumper wire is connected to two second initialization signal lines 122 adjacent in the first direction, and the second jumper wire is connected to the second initialization signal line 122, and a mesh parallel structure can also be formed. The overall resistance of the mesh parallel structure is less than the resistance of the second initialization signal line 122, which can reduce the voltage drop on the second initialization signal line 122, improve the voltage uniformity of the initialization signal on each second initialization signal line 122, and thus improve the display uniformity of the display panel. Similarly, the second jumper wire is located in the anode conductive layer 13, and can also avoid occupying the routing space of the drive circuit layer 12, which is conducive to reducing the number of conductive layers in the drive circuit layer 12.

[0079] Among them, since the first initialization signal line 121 and the second initialization signal line 122 are arranged alternately, the second jumper line also needs to be arranged at intervals from the anode structure 132 and the first jumper line 131, that is, the anode structure 132-first jumper line 131-second jumper line can be a group and arranged in sequence in the anode conductive layer 13 to achieve uniform distribution of the above structure on the display panel.

[0080] In one embodiment, Figure 4 As shown, the driving circuit layer 12 includes: a first conductive layer 1201, an insulating layer and a second conductive layer 1202. It should be noted that Figure 4 As shown, a buffer layer 14 may be further disposed between the substrate 11 and the driving circuit layer 12 .

[0081] The first conductive layer 1201 includes a plurality of gate structures 123 arranged at intervals. The insulating layer is located on a side of the first conductive layer 1201 away from the substrate 11. The second conductive layer 1202 is located on a side of the insulating layer away from the first conductive layer 1201 and includes a plurality of first initialization signal lines 121.

[0082] The first conductive layer 1201 and the second conductive layer 1202 may be conductive metal layers respectively.

[0083] It can be understood that the driving circuit layer 12 includes a plurality of pixel circuits, and the pixel circuits include a plurality of low-temperature polysilicon transistors, and the gate structure 123 of the low-temperature polysilicon transistor is located in the first conductive layer 1201. The insulating layer is located between the first conductive layer 1201 and the second conductive layer 1202, and is used to isolate the first conductive layer 1201 from the second conductive layer 1202, so as to avoid electrical connection between the first conductive layer 1201 and the second conductive layer 1202. The first initialization signal line 121 is located in the second conductive layer 1202, and the first initialization signal line 121 can be connected to the active layer 124 of the corresponding low-temperature polysilicon transistor through a conductive via, so that the first initialization signal line 121 transmits the initialization signal to one electrode of the corresponding low-temperature polysilicon transistor, and the output of the initialization signal can be controlled by controlling the on and off of the low-temperature polysilicon transistor.

[0084] In combination with the scheme of the aforementioned embodiment, the first jumper line 131 is located in the anode conductive layer 13, and the driving circuit layer 12 does not require an additional third conductive layer, so that the first jumper line 131 can be formed in the display panel of the two conductive layers. The first jumper line 131 can be connected to two adjacent first initialization signal lines 121 through conductive vias to form a mesh parallel structure, thereby reducing the voltage drop of the initialization signal on the first initialization signal line 121, thereby improving display uniformity.

[0085] In one embodiment, Figure 4 As shown, the driving circuit layer 12 further includes an active layer 124 , and the first initialization signal line 121 is connected to the active layer 124 .

[0086] In one example, the first initialization signal line 121 is used to transmit an anode initialization signal, and the pixel circuit includes a first initialization transistor, a first electrode of the first initialization transistor is connected to the first initialization signal line 121, and a second electrode of the first initialization transistor is connected to the anode of the light-emitting element, that is, the active layer 124 of the first initialization transistor is connected to the first initialization signal line 121. When the first initialization transistor is turned on, the anode initialization signal is output to the anode of the light-emitting element through the first initialization transistor, thereby resetting the anode voltage of the light-emitting element, thereby improving the uniformity of the anode voltage of each light-emitting element, and further improving the display uniformity of the display panel.

[0087] In another example, the first initialization signal line 121 also transmits a gate initialization signal, and the pixel circuit includes a second initialization transistor, a first electrode of the second initialization transistor is connected to the first initialization signal line 121, and a second electrode of the second initialization transistor is connected to the gate of the driving transistor, that is, the active layer 124 of the second initialization transistor is connected to the first initialization signal line 121. When the first initialization transistor is turned on, the gate initialization signal is output to the gate of the driving transistor through the second initialization transistor, thereby resetting the gate of the driving transistor, thereby improving the uniformity of the brightness of each light-emitting element, and further improving the display uniformity of the display panel.

[0088] In one embodiment, the driving circuit layer 12 includes multiple insulating layers and at least three conductive layers away from the substrate 11, at least one insulating layer is disposed between two adjacent conductive layers, and the first initialization signal line 121 is located in any conductive layer except the bottom conductive layer.

[0089] The bottom conductive layer is the conductive layer where the gate structure 123 is located.

[0090] In applications, the driving circuit layer 12 may need to include multiple conductive layers. In this case, the driving circuit layer 12 often includes multiple insulating layers away from the substrate 11 and at least three conductive layers. The first initialization signal line 121 can be located in any conductive layer except the bottom conductive layer.

[0091] It should be noted that no matter which conductive layer the first initialization signal line 121 is located in, the first jumper line 131 can be connected to the first initialization signal line 121 through a conductive via to form a mesh parallel structure, thereby reducing the voltage drop on the first initialization signal line 121 during the transmission of the initialization signal and improving display uniformity.

[0092] For example, for a display panel designed with LTPS (Low Temperature Poly-Silicon), since the display panel does not include metal oxide transistors, there is no need to set corresponding signal lines for the metal oxide transistors. Therefore, the number of signal lines in the display panel designed with LTPS is relatively small. For a display panel designed with LTPO (Low Temperature Polysilicon Oxide), since the display panel includes metal oxide transistors, corresponding signal lines need to be set for the metal oxide transistors. Therefore, the number of signal lines in the display panel designed with LTPO is relatively large. Then the driving circuit layer 12 often needs to include multiple conductive layers. In this case, the driving circuit layer 12 often includes multiple insulating layers away from the substrate 11 and at least three conductive layers. The first initialization signal line 121 can be located in any conductive layer except the bottom conductive layer.

[0093] In one embodiment, if Figure 2 and Figure 3 As shown, the first jumper wires 131 adjacent to each other in the first direction are arranged in a staggered manner in the second direction.

[0094] It can be understood that the first jumper line 131 is located in the anode conductive layer 13, and the first jumper line 131 needs to be spaced apart from the anode structure 132. The first jumper lines 131 adjacent to each other in the first direction are staggered in the second direction, so that the first jumper line 131 can effectively avoid the anode structure 132, thereby realizing the spaced setting of the first jumper line 131 and the anode structure 132.

[0095] In one embodiment, if Figure 2 and Figure 3 As shown, the plurality of first jumper wires 131 in the second direction are arranged at equal intervals. It can be understood that the arrangement of the plurality of first jumper wires 131 at equal intervals is conducive to a reasonable layout of the routing space, so that the routing is uniform and orderly.

[0096] In one embodiment, Figure 5 As shown, the display panel may further include a pixel definition layer 15 and a cathode layer 17. The pixel definition layer 15 is located on the side of the anode conductive layer 13 away from the substrate 11. The pixel definition layer 15 defines a pixel opening. A light-emitting element 16 is provided in the pixel opening. The cathode layer 17 is located on the side of the light-emitting element 16 away from the substrate 11.

[0097] Based on the same inventive concept, Figure 6 and Figure 7 As shown, the present application also provides a method for manufacturing a display panel, and the method for manufacturing a display panel includes the following steps S601 to S603.

[0098] S601: providing a substrate.

[0099] Among them, the substrate 11 may include a hard substrate 11 such as glass, metal foil, etc., and may also include a flexible substrate 11 made of similar materials such as polyimide (PI), polycarbonate (PC), polystyrene (PS), polyethylene (PE), polyvinyl chloride (PV), polyvinyl pyrrolidone (PVP), polyethylene terephthalate (PET), etc. The substrate 11 mainly plays a supporting role.

[0100] S602: forming a driving circuit layer on one side of the substrate, wherein the driving circuit layer comprises a plurality of first initialization signal lines, each of which is arranged along a first direction and extends along a second direction, wherein the first direction intersects the second direction.

[0101] Among them, the first initialization signal line 121 is used to transmit an initialization signal to the pixel circuit driving the crystal gate potential or the light-emitting element anode, so as to reset the pixel circuit driving the crystal gate potential or the light-emitting element anode potential, thereby improving the uniformity of the pixel circuit driving the crystal gate potential or the light-emitting element anode potential, and further improving the display uniformity of the display panel.

[0102] S603: forming an anode conductive layer on a side of the driving circuit layer away from the substrate, wherein the anode conductive layer includes a plurality of anode structures and a plurality of first jumper wires, wherein the first jumper wires are used to connect two first initialization signal lines adjacent to each other in a first direction.

[0103] The anode structure 132 is the anode of the light emitting element.

[0104] In this embodiment, the anode conductive layer 13 includes a plurality of anode structures 132 and a plurality of first jumper wires 131, the anode structures 132 and the first jumper wires 131 are arranged at intervals, and the first jumper wires 131 are connected to two first initialization signal lines 121 adjacent to each other in the first direction, and the first jumper wires 131 are connected to the first initialization signal lines 121, so that a mesh parallel structure can be formed, and the overall resistance of the mesh parallel structure is less than the resistance of the first initialization signal line 121, so that the voltage drop on the first initialization signal line 121 can be reduced, and the voltage uniformity on each first initialization signal line 121 can be improved, thereby improving the uniformity of the initialization signal, and further improving the display uniformity of the display panel. In addition, since the first jumper wires 131 are located in the anode conductive layer 13, the first jumper wires 131 do not need to occupy the routing space of the drive circuit layer 12, which is conducive to reducing the number of conductive layers in the drive circuit layer 12, and the conductive layer data of the display panel can be reduced, which is conducive to reducing the manufacturing cost of the display panel.

[0105] The manufacturing method of the display panel is as follows: a driving circuit layer 12 is formed on one side of the substrate 11, and an anode conductive layer 13 is formed on the side of the driving circuit layer 12 away from the substrate 11, thereby forming a plurality of first initialization signal lines 121 and a plurality of first jumper lines 131, and the first jumper line 131 connects two adjacent first initialization signal lines 121, so that the first jumper line 131 and the first initialization signal line 121 form a mesh parallel structure, and the overall resistance of the mesh parallel structure is less than the resistance of the first initialization signal line 121, so that the voltage drop on the first initialization signal line 121 can be reduced, and the voltage uniformity of the initialization signal on each first initialization signal line 121 can be improved, thereby improving the display effect of the display panel. Moreover, since the first jumper line 131 is located in the anode conductive layer 13, the first jumper line 131 does not need to occupy the routing space of the driving circuit layer 12, which is conducive to reducing the number of conductive layers in the driving circuit layer 12 and reducing the manufacturing cost of the display panel.

[0106] In one embodiment, in S602, forming a driving circuit layer on one side of the substrate includes: forming a first conductive layer on one side of the substrate 11; forming a second conductive material layer on a side of the first conductive layer away from the substrate; and patterning the second conductive material layer to form a plurality of first initialization signal lines.

[0107] The first conductive layer 1201 and the second conductive layer 1202 can be conductive metal layers, respectively. It is understood that the "patterning process" mentioned herein, when the material to be patterned is an inorganic material or metal, "patterning process" may include processes such as coating photoresist, mask exposure, development, etching, and stripping photoresist, and when the material to be patterned is an organic material, "patterning process" may include processes such as mask exposure and development, and the evaporation, deposition, coating, and coating mentioned herein are all mature preparation processes in the relevant technology.

[0108] In this embodiment, the first jumper line 131 is located in the anode conductive layer 13, and the first initialization signal line 121 is located in the second conductive layer 1202. The first jumper line 131 can be connected to the first initialization signal line 121 through a conductive via to form a mesh parallel structure, thereby reducing the voltage drop during the transmission of the initialization signal on the first initialization signal line 121 and improving display uniformity. Since the second jumper line is located in the anode conductive layer 13, it can also avoid occupying the routing space of the drive circuit layer 12, thereby helping to reduce the number of conductive layers in the drive circuit layer 12.

[0109] In one embodiment, in S603, forming an anode conductive layer on the side of the driving circuit layer away from the substrate includes: forming an anode material layer on the side of the driving circuit layer away from the substrate; and patterning the anode material layer to form multiple anode structures and multiple first jumper wires.

[0110] It can be understood that the anode structure 132 is the anode of the light-emitting element, and the anode structure 132 and the first jumper wire 131 are located in the same layer, that is, the first jumper wire 131 is located in the anode conductive layer 13. Therefore, the first jumper wire 131 does not need to occupy the routing space of the driving circuit layer 12, which is beneficial to reduce the number of conductive layers in the driving circuit layer 12, so the conductive layer data of the display panel can be reduced, which is beneficial to reduce the production cost of the display panel.

Moreover, since the first jumper wire is located in the anode conductive layer, the first jumper wire does not need to occupy the routing space of the driving circuit layer, which is conducive to reducing the number of conductive layers in the driving circuit layer and reducing the production cost of the display panel.
