     DETAILED DESCRIPTION 
     The present disclosure is further described below in detail in conjunction with the drawings and embodiments. It is to be understood that the embodiments described herein are merely intended to explain the present disclosure and are not intended to limit the present disclosure. Additionally, it should be noted that for ease of description, only the part, instead of all, related to the present disclosure is illustrated in the drawings. 
       FIG.  1    is a structural view of a display panel in the related art. In one embodiment,  FIG.  1    illustrates a film structure of an organic light-emitting display panel integrated with a touch function. The touch function may be implemented through the principle of TP on the TFE (TPOT). As shown in  FIG.  1   , the display panel includes a driver circuit layer  12 ′, an anode layer  15 ′, an organic light-emitting layer  151 ′, a cathode layer  152 ′ and an encapsulation layer  19 ′ which are sequentially disposed on a substrate  11 ′. A touch circuit layer  21 ′ is formed by directly using the encapsulation layer  19 ′ as a substrate. The touch circuit layer  21 ′ includes at least one layer of touch electrodes to implement the touch function, and the touch circuit layer  21 ′ may further be provided with structures such as a polarizer  20 ′. However, in the process of implementing the disclosure, it is found that the above film structure is complex in wiring and occupies a large space, bringing a poor experience to a user. An embodiment of the present disclosure provides a display panel. The display panel includes a substrate, a drive module layer, a first auxiliary layer, an anode layer, an organic light-emitting layer, a cathode layer and an auxiliary conductive portion. 
     The drive module layer, the first auxiliary layer, the anode layer, the organic light-emitting layer and the cathode layer are sequentially disposed on the substrate. The drive module layer is provided with multiple drive modules; and the anode layer includes multiple blocky anodes. 
     The projection of at least part of the auxiliary conductive portion in a direction perpendicular to the substrate is located among the multiple blocky anodes. 
     At least one jumper layer is disposed between the drive module layer and the first auxiliary layer. The jumper layer is disposed on a side of the auxiliary conductive portion close to the substrate; the jumper layer includes multiple jumper portions; the blocky anode is electrically connected to a drive module corresponding to the blocky anode through one jumper portion. 
     On the direction perpendicular to the substrate, the auxiliary conductive portion at least partially overlaps the multiple jumper portions. 
     In the present disclosure, a display panel includes a drive module layer, a first auxiliary layer, an anode layer, an organic light-emitting layer and a cathode layer which are sequentially disposed on a substrate. The drive module layer is provided with multiple drive modules; and the anode layer is provided with blocky anodes corresponding to the drive modules. The display panel is further provided with an auxiliary conductive portion which is insulated from the blocky anodes. In addition, at least one jumper layer is disposed between the drive module layer and the first auxiliary layer, so that the blocky anode is electrically connected to a drive module corresponding to the blocky anode through one jumper portion. On a plane where the substrate is located, the auxiliary conductive portion at least partially overlaps the multiple jumper portions. Therefore, through the bridging between film layers achieved by the jumper portions, the area of a connection portion for connecting a blocky anode and a drive module can be reduced, which is conducive to increasing the width of a gap region between blocky anodes, saving space for the layout of the auxiliary conductive portion, and preventing the problem that the gap region is too narrow to dispose the auxiliary conductive portion. In this way, the width of the auxiliary conductive portion may be set to be slightly wider, so that the difficulty of the process of disposing the auxiliary conductive portion is reduced, the process of manufacturing the display panel is accelerated, and the manufacturing quality of the display panel is improved. 
       FIG.  2    is a structural view of a display panel according to an embodiment of the present disclosure. As shown in  FIG.  2   , a display panel includes a substrate  11  and a drive module layer  12 , a first auxiliary layer  14 , an anode layer  15 , an organic light-emitting layer  151  and a cathode layer  152  which are sequentially disposed on the substrate  11 . The stacked structure formed by the anode layer  15 , the organic light-emitting layer  151  and the cathode layer  152  may form an OLED light-emitting structure to emit light required for display. In one embodiment, the anode layer  15  includes multiple discrete blocky anodes  15   b , and all of the blocky anodes  15   b  are stacked with the organic light-emitting layer  151  and the cathode layer  152  to form multiple discrete subpixels  153 . The drive module layer  12  is provided with multiple drive modules  120 , and the drive modules  120  may be disposed in correspondence to the subpixels  153 . In an embodiment, the drive modules  120  are disposed in one-to-one correspondence the subpixels  153 , and the drive module  120  transmits an anode voltage to the corresponding blocky anode  15   b  to drive the subpixel  153  to emit light. Optionally, the first auxiliary layer is a planarization layer. 
     In the present disclosure, the display panel may further be provided with an auxiliary conductive portion  15   a . Referring to  FIG.  3   ,  FIG.  3    is a top structural view of a display panel according to an embodiment of the present disclosure. The display panel includes the auxiliary conductive portion  15   a . On a plane parallel to a plane where the substrate  11  is located, the auxiliary conductive portion  15   a  is disposed in a gap region d 1  between adjacent two blocky anodes  15   b  and is not connected to the blocky anodes  15   b . That is, the auxiliary conductive portion  15   a  is disposed insulated from adjacent blocky anodes  15   b . Referring to  FIG.  4   ,  FIG.  4    is a structural view of a comparative example of a display panel according to an embodiment of the present disclosure. Since the comparative example shown in  FIG.  4    is not provided with an auxiliary conductive portion, in order to connect the blocky anode  15   b ′ and the corresponding drive module, a relatively long connection portion  151   b ′ needs to be disposed in the gap region between the blocky anodes  15   b ′, so that the width of the gap region is relatively small, and thus it is difficult to dispose the connection portion  151   b′.    
     Referring to  FIG.  2    and  FIG.  3   , at least one jumper layer  13  may further be disposed between the drive module layer  14  and the first auxiliary layer  12 . Since the auxiliary conductive portion  15   a  needs to be disposed between adjacent blocky anodes  15   b , it is necessary to reserve a relatively wide range for the gap region d 1  between adjacent blocky anodes  15   b  for ease of disposing the auxiliary conductive portion  15   a . In the embodiment, the auxiliary conductive portion  15   a  and the blocky anodes  15   b  may be disposed in a same layer as shown in  FIG.  2   , or the auxiliary conductive portion  15   a  and the blocky anodes  15   b  may be disposed in different layers, as long as it is ensured that the auxiliary conductive portion  15   a  is disposed in the gap region between adjacent two blocky anodes  15   b  on the plane parallel to the plane where the substrate  11  is located and does not block the area directly facing the blocky anode  15   b  and the cathode layer. In this embodiment, the auxiliary conductive portion  15   a  may be an information transmission line, for example, a signal line through which a driver circuit transmits an initialization signal, a reset and a fixed signal, or a signal line to be in parallel with other signal lines to reduce resistance. Further, the auxiliary conductive portion  15   a  is disposed to form capacitance between the cathode layer and the auxiliary conductive portion  15   a  to maintain a stable potential of the cathode layer, so that the auxiliary conductive portion  15   a  should be disposed as close to the cathode layer as possible. The auxiliary conductive portion  15   a  may be disposed in the anode layer and is disposed in a same layer as the blocky anodes  15   b , or the auxiliary conductive portion  15   a  may be disposed on a side of the anode layer close to the cathode layer, enhancing the effect of stabilizing the potential on the cathode layer by the auxiliary conductive portion  15   a  and improving the stability of a display picture of the display panel. 
     In an embodiment, the organic light-emitting display panel in the embodiment may be integrated with a touch function, for example, a touch electrode layer may be disposed. The touch electrode layer may be embedded in the organic light-emitting display panel or may be disposed on a display side of the organic light-emitting display panel, and the position at which the touch electrode layer is disposed is not limited in the embodiment. A cathode of a display panel is always on to stabilize a low potential. The cathode is easily to produce potential fluctuations due to a current when the organic light-emitting layer emits light, causing the problem of instability of the cathode potential. Moreover, parasitic capacitance may be produced between the touch electrode layer and the cathode with unstable potential, which easily affects the touch performance of a touch anode layer. According to the embodiment, on the plane where the substrate is located, the auxiliary conductive portion is disposed in the gap region between adjacent blocky anodes, capacitance is formed between the auxiliary conductive portion and the cathode layer, so that the potential of the cathode layer is stabilized, and the problem of unstable cathode potential caused by a current between the anode and the cathode is effectively avoided. Therefore, the brightness of the display panel is kept stable, and the display quality of the display panel is improved. 
     In an embodiment, the material of the auxiliary conductive portion  15   a  may generally include at least one of indium tin oxide or silver. However, for the above materials, a relatively small line width is technically difficult to achieve. Therefore, if the pixel density is relatively large, a relatively large process risk is easily to occur. For example, it is easily to cause a problem that the auxiliary conductive portion  15   a  cannot be connected or is easily broken due to a relatively small line width. On this basis, in order to maintain a high pixel density on the display panel and to ensure that a relatively wide range is reserved for the gap region d 1 , at least one jumper layer  13  may be disposed on a side of the auxiliary conductive portion  15   a  close to the substrate  11 . The jumper layer  13  includes multiple jumper portions  131 , and a blocky anode  15   b  is electrically connected to a drive module  120  corresponding to the blocky anode  15   b  through one jumper portion  131 , so that the setting of a connection portion  151   b  extending from the blocky anode  15   b  is reduced (in the embodiment, the blocky anode  15   b  may include an anode body and a connection portion  151   b  extending from the anode body), and thus the connection portion  151   b  is prevented from occupying too much space of the gap region d 1 . In an embodiment, on the plane parallel to the plane where the substrate  11  is located, the auxiliary conductive portion  15   a  at least partially overlaps the multiple jumper portions  131 . As shown in  FIG.  5   ,  FIG.  5    is an enlarged structural view of a local region A 1  of the display panel in  FIG.  3   . An overlapped region exists between the auxiliary conductive portion  15   a  and the jumper portion  131 , thus the connection portion  151   b  of the blocky anode  15   b  does not need to extend to the position at which the drive module is disposed, which is conductive to increasing the width of the gap region d 1  between blocky anodes  15   b  to implement the layout of the auxiliary conductive portion  15   a , and preventing the problem that the gap region d 1  is too narrow to dispose the auxiliary conductive portion. In this way, the width of the auxiliary conductive portion  15   a  may be set to be slightly wider, so that the difficulty of the process of disposing the auxiliary conductive portion  15   a  is reduced, the process of manufacturing the display panel is accelerated, and the manufacturing quality of the display panel is improved.  FIG.  6    is a top structural view of a comparative example of a display panel according to an embodiment of the present disclosure. In the comparative example, the above auxiliary conductive portion is not disposed, the drive modules are disposed in a matrix, and the blocky anodes  15   b  may be disposed in many different modes. For example, as shown in  FIG.  6   , the blocky anodes  15   b ′ may be disposed in a triangle mode, so that part of the blocky anodes  15   b ′ need to be provided with long connection portions  151   b ′ for being connected to the corresponding drive modules. Therefore, a large space of the gap region d 1 ′ is occupied, the auxiliary conductive portion  15   a ′ cannot be set to a relatively large width, and thus the process risk is relatively large. 
     The drive module layer includes a driver circuit formed by multiple metal layers and insulating layers. In an embodiment, with continued reference to  FIG.  2   , the drive module layer  12  includes: an active layer  122  disposed on the substrate  11 ; a gate electrode insulating layer  123  disposed on a side of the active layer  122  facing away from the substrate  11 ; a gate electrode layer  124  which is disposed on a side of the gate electrode insulating layer  123  facing away from the substrate  11  and is provided with a first capacitive electrode and a gate electrode of a drive module; a capacitive dielectric layer  125  disposed on a side of the gate electrode layer  124  facing away from the substrate  11 ; a capacitive electrode layer  126  which is disposed on a side of the capacitive dielectric layer  125  facing away from the substrate  11  and is provided with a second capacitive electrode; an interlayer insulating layer  127  disposed on a side of the capacitive electrode layer  126  facing away from the substrate  11 ; a source-drain electrode layer  128  which is disposed on a side of the interlayer insulating layer  127  facing away from the substrate  11  and is provided with a source electrode  1201  and drain electrode  1202  of the drive module  120 ; and a passivation layer  129  disposed on a side of the source-drain electrode layer  128  facing away from the substrate  11 . In addition, a buffer layer  121  and the like may further be disposed between the substrate  11  and the active layer  122 , or the drive module layer  12  may further include other metal layers or non-metal layers, which is not limited in the embodiment. It should be noted that in the top views of the display panel shown in  FIG.  3    and  FIG.  6   , not entire film structure of the drive module layer  12  is illustrated. In order to obtain a clear relative relationship of the overlapping position between the auxiliary conductive portion and the jumper portion, only the source-drain electrode layer  128  of the drive module layer  12  is illustrated to characterize the position of the drive modules, and a relative positional relationship of the anode layer  15 , the auxiliary conductive portion  15   a  and the jumper layer  13  is illustrated. 
     With continued reference to  FIG.  3   , in an embodiment, the drive modules may be disposed in a matrix. The drive modules are disposed in rows along a first direction X, and the drive modules are disposed in columns along a second direction Y; and the first direction X intersects the second direction Y. The blocky anodes  15   b  include a first blocky anode  152   b , a second blocky anode  153   b  and a third blocky anode  154   b  which are disposed in a triangle mode; the first blocky anode  152   b  and the second blocky anode  153   b  in a same triangle are disposed in a column along the second direction Y; and the drive modules connected to blocky anodes  15   b  in a same triangle are disposed in a same row along the first direction X. 
     As mentioned above,  FIG.  3    does not illustrate the complete structure of the drive module and only illustrates the source-drain electrode layer  128  including a data line  1281 , a power signal line  1282 , a source electrode  1201  and a drain electrode. Since the drive module is electrically connected to the blocky anode  15   b  through the source electrode  1201 , the position of the drive module may be characterized by the position of the source electrode  1201  in  FIG.  3   . As shown in  FIG.  2   , the source electrodes  1201  of all drive modules may be disposed in a matrix along the first direction X and the second direction Y respectively. The first direction X is used as the row direction, the second direction Y is used as the column direction, and the first direction X intersects the second direction Y In an embodiment, the first direction X and the second direction Y may be disposed perpendicular to each other, so that the drive modules are disposed in a matrix, but in the embodiment, the blocky anodes  15   b  are disposed in a triangle mode. In one embodiment, as shown in  FIG.  3   , the blocky anodes  15   b  include the first blocky anode  152   b , the second blocky anode  153   b  and the third blocky anode  154   b  which are disposed in a triangle mode; the first blocky anode  152   b  and the second blocky anode  153   b  in a same triangle are disposed in a column along the second direction Y; and along the first direction X, the third blocky anode  154   b  is disposed at a position between the first blocky anode  152   b  and the second blocky anode  153   b , forming a triangle shape. Referring to  FIG.  3   , the source electrodes  1201  of the drive modules connected to the blocky anodes  15   b  in a same triangle are disposed in a same row along the first direction X, that is, the drive modules connected to the blocky anodes  15   b  in a same triangle are disposed in a same row along the first direction X. It should be noted that the first blocky anode  152   b  and the second blocky anode  153   b  are disposed in a column along the second direction Y. If the drive module of the first blocky anode  152   b  and the drive module of the second blocky anode  153   b  are disposed in a same row, one of the first blocky anode  152   b  and the second blocky anode  153   b  needs to be connected to the corresponding drive module through a strip-shaped jumper portion  131 . For example, the second blocky anode  153   b  shown in  FIG.  3    is connected to the corresponding drive module through a jumper portion  131 . In this embodiment, the jumper portion  131  is disposed, so that it is prevented that the second blocky anode  153   b  extends a relatively long connection portion  151   b  for being connected to the corresponding drive module, and the space of the gap region d 1  is saved. Moreover, an overlapped region between the auxiliary conductive portion  15   a  and the jumper portion  131  exits, which is conductive to further increasing the width of the gap region d 1  between the blocky anodes  15   b  to implement the layout of the auxiliary conductive portion  15   a  and reducing the difficulty of the process of disposing the auxiliary conductive portion  15   a . In addition, the display quality is improved without sacrificing the pixel resolution while the width of the gap region d 1  is increased. 
     In an embodiment, with continued reference to  FIG.  3    and  FIG.  5   , a jumper portion  131  may include a first end  1311  and a second end  1312 ; the drive module is connected to a first end  1311  of a jumper portion  131  corresponding to the drive module; the blocky anode  15   b  is connected to a second end  1312  of a jumper portion  131  corresponding to the blocky anode  15   b ; a first end  1311  of at least one jumper portion dose not overlap the blocky anode  15   b ; a first end  1311  of at least one jumper portion  131  overlaps the blocky anode  15   b.    
     In this embodiment, the jumper portion  131  includes two connection ends connected to each other: the first end  1311  and the second end  1312 . The drive module is connected to the first end  1311  of a jumper portion  131 , and the corresponding blocky electrode  15   b  is connected to the second end  1312  of the jumper portion  131 , so that an electrical connection is established between the drive module and the blocky anode  15   b . As shown in  FIG.  5   , when the blocky anode  15   b  is relatively far away from the corresponding drive module, the blocky anode  15   b  may be connected to the corresponding drive module through an elongated jumper portion  131 , so that a case where the first end  1311  of the jumper portion  131  does not overlap the blocky anode  15   b  exits, that is, a case of the setting of the local region A 1  exits. In addition, as shown in a local region A 2  in  FIG.  3   , a case where the blocky anode  15   b  is relatively close to the corresponding drive module exits in this embodiment, the drive module overlaps the blocky anode  15   b , so that the first end  1311  of the corresponding jumper portion  131  overlaps the blocky anode  15   b . In one embodiment, the first end  1311  of the jumper portion  131  may partially overlap the blocky anode  15   b , as shown in a local region A 3  in  FIG.  3   . Of course, on the plane where the substrate  11  is located, the blocky anode  15   b  may also completely overlap the first end  1311  of the jumper portion  131 , as shown in the local region A 2  in  FIG.  3   . In this embodiment, the arrangement of the blocky nodes  15   b  may be adapted to the arrangement of the drive modules according to the arrangement of the subpixels in a triangle or a rectangle, so that the corresponding drive modules and the blocky anodes  15   b  are connected through the jumper portions  131 . Therefore, it is avoided that the blocky anode  15   b  extends a relatively long connection portion  151   b , the area of the gap region d 1  is increased, the layout of the auxiliary conductive portion is facilitated, the difficulty of the process of disposing the auxiliary conductive portion on the display panel with the subpixels disposed in a triangle is reduced, the cathode potential is maintained to be stable, and the display quality is improved. 
     With continued reference to  FIG.  2   , in an embodiment, at least one blocky anode  15   b  is electrically connected to a second end  1312  of a jumper portion  131 , which is corresponding to the blocky anodes  15   b , of the jumper layer  13  through a first through hole K 1  penetrating through the first auxiliary layer  14 . A vertical projection of the first through hole K 1  on the plane where the substrate  11  is located is located within a blocky anode  15   b  corresponding to the first through hole K 1 . 
       FIG.  2    is a sectional view taken along a segment C-C′ of the display panel in  FIG.  3   . As can be seen from  FIG.  2   , the blocky anode  15   b  may be electrically connected to the second end  1312  of the corresponding jumper portion  131  through the first through hole K 1  penetrating through the first auxiliary layer  14 . As can be seen from  FIG.  3   , the first through hole K 1  is overlapped by the corresponding blocky anode  15   b  on the plane where the substrate  11  is located, so that the first through hole K 1  does not occupy the space of the gap region, which is conductive to implementing the layout of the auxiliary conductive portion in the gap region and improving the process quality of the auxiliary conductive portion. 
       FIG.  7    is a partial view of a top view of another display panel according to an embodiment of the present disclosure. In an embodiment, on the plane parallel to the plane where the substrate  11  is located, at least one blocky anode  15   b  is a polygon. The vertical projection of the first through hole K 1  on the plane where the substrate  11  is located is within a first connection region M 1 ; and the first connection region M 1  is a region, within the polygon, which is closest to the first end  1311  of the jumper portion  131 . 
     Referring to  FIG.  3    and  FIG.  7   , the blocky anode  15   b  may be a rectangle. Of course, the blocky anode  15   b  in the embodiment may also be rhombuses, circles, ellipses, polygons and the like, which is not limited in the embodiment. In an embodiment, as shown in  FIG.  7   , the blocky anode  15   b  is a rounded rectangle, so that the manufacturing process is simple, rigid cracking is not easily to occur, and the quality of the manufactured panel is improved. As shown in  FIG.  7   , on the plane where the substrate  11  is located, the first through hole K 1  is overlapped by the blocky anode  15   b , and the first through hole K 1  is located within the first connection region M 1  within the blocky anode  15   b . In this embodiment, the first connection region M 1  is a region, within the polygonal blocky anode  15   b , which is closest to the first end  1311  of the jumper portion  131  in a straight line. The first through hole K 1  is disposed in the above first connection region M 1 , so that the jumper portion  131  may further be disposed only in the first connection region M 1 , and the first connection region M 1  is closest to the first end  1311  of the jumper portion  131  in a straight line. The length and area of the jumper portion  131  are minimized, capacitance between the jumper portion  131  and the anode layer  15  is avoided, thus the impact on the potential of the anode layer  15  is avoided, accurate dimming on the subpixels by the anode potential of the anode layer  15  is achieved, and the display quality is improved. 
     With continued reference to  FIG.  3   , as shown in the local region A 2 , in an embodiment, a vertical projection of at least one jumper portion  131  on the plane where the substrate  11  is located is located within the corresponding blocky anodes  15   b . In the way, on the plane where the substrate  11  is located, the first end  1311  and second end  1312  of the jumper portion  131  are overlapped by the corresponding blocky anodes  15   b , so that the first end  1311  and second end  1312  of the jumper portion  131  do not occupy the area of the gap region d 1  between the blocky anodes  15   b , thus the auxiliary conductive portions  15   a  can be arranged relatively dense, and the stability of the potential of the cathode layer  152  of the display panel is further improved. In addition, whether corresponding to the drive module or not, the blocky anode  15   b  may be provided with a structure for being connected through the jumper portion  131 , so that it is avoided that the resistance difference between different anodes and connection sections of the drive modules is too large, and the consistency of the electrical performance is effectively improved. 
     In an embodiment, the auxiliary conductive portion may further be used as an initialization signal line of the drive module. In order to form capacitance with the cathode layer, the auxiliary conductive portion needs to be connected to a fixed potential. Exemplarily, the auxiliary conductive portion may be connected to a zero potential or directly connected to a ground terminal of the display panel. In this embodiment, different fixed potentials may be selected for the auxiliary conductive portion  15   a , and the embodiment does not limit the specific potential. The drive module in the embodiment generally includes an initialization unit, a reset unit, a data write unit, a drive unit and a light-emitting control unit. The data write unit is configured to write a data voltage into the drive unit in a data write stage; the reset module is configured to provide a reset signal to a light-emitting element; and the drive unit is configured to drive the light-emitting control unit according to the data voltage. The drive module needs to be connected with a data line, an initialization signal line, a gate line, a light-emitting control signal line and the like. In the embodiment, the auxiliary conductive portion may be led to the drive module layer through a via to be used as the initialization signal line and be electrically connected to the initialization unit, so that the wiring arrangement of the drive module is saved, and the manufacturing process of the display panel is simplified. 
       FIG.  8    is a structural view of another display panel according to an embodiment of the present disclosure. In an embodiment, the display panel may further include an encapsulation layer  20  and a touch layer  21 . The encapsulation layer  20  is disposed on a side of the cathode layer  152  facing away from the substrate  11 ; and the touch layer  21  is disposed on a side of the encapsulation layer  20  facing away from the substrate  11 . The touch layer  21  includes a metal grid structure; on the plane parallel to the plane where the substrate  11  is located, the metal grid structure is disposed between the blocky anodes  15   b  and overlaps the auxiliary conductive portion  15   a.    
     In this embodiment, the display panel may be a touch display panel, for example, a display panel in the form of a TPOT. As shown in  FIG.  8   , on the basis of the structure of the display panel in  FIG.  2   , the display panel may further be provided with the encapsulation layer  20  and the touch layer  21  sequentially on the cathode layer  152 , and the touch layer  21  may include touch electrodes  211  disposed in an array, and the touch electrodes  211  in this embodiment may be composed of the metal grid structure. 
     In one embodiment, a touch electrode  211  includes multiple metal wires, and the metal wires cross each other to form metal grids. On the plane parallel to the plane where the substrate  11  is located, the metal grids are located between adjacent blocky anodes  15   b  to avoid blocking the light emitted by the subpixels, that is, meshes of the metal grids corresponds to the openings of a subpixel definition layer. In addition, on the plane parallel to the plane where the substrate  11  is located, the metal grid structure at least partially overlaps the auxiliary conductive portion  15   a . In this embodiment, a vertical projection of the auxiliary conductive portion  15   a  on the substrate  11  may be disposed to completely overlap the metal grid structure. Therefore, the auxiliary conductive portion  15   a  serves as a metal shielding layer, so that the impact of the metal grid structure on a metal-material layer of the drive module layer can be effectively prevented. In addition, the auxiliary conductive portion  15   a  in the embodiment may correspond to the path of the grid line of the touch electrode  211 , which saves space and minimizes the parasitic capacitance between layers. 
       FIG.  9    is a top structural view of another display panel according to an embodiment of the present disclosure. In an embodiment, the auxiliary conductive portion  15   a  may include multiple first auxiliary conductive portion segments  151   a  extending along the second direction Y; and on the plane parallel to the plane where the substrate  11  is located, a first auxiliary conductive portion segment  151   a  is disposed between adjacent two columns of blocky anodes  15   b . Adjacent two first auxiliary conductive portion segments  151   a  are connected through a second auxiliary conductive portion segment  152   a ; and on the plane parallel to the plane where the substrate  11  is located, the second auxiliary conductive portion segment  152   a  is disposed between a first blocky anode  152   b  and a second blocky anode  153   b  which are adjacent to each other or between adjacent two third blocky anodes  154   b.    
     In this embodiment, the auxiliary conductive portion  15   a  may include multiple first auxiliary conductive portion segments  151   a  extending along a same direction, and adjacent two first auxiliary conductive portion segments  151   a  may be connected through a second auxiliary conductive portion segment  152   a . As shown in  FIG.  9   , the first auxiliary conductive portion segment  151   a  may extend along the second direction Y, and the first auxiliary conductive portion segment  151   a  is disposed between adjacent two columns of blocky anodes  15   b . The second auxiliary conductive portion segment  152   a  may extend along the first direction X and is disposed between adjacent two rows of blocky anodes  15   b . The blocky anodes illustrated in  FIG.  9    are disposed in triangles. Therefore, on the plane where the substrate  11  is located, the second auxiliary conductive portion segment  152   a  is disposed between a first blocky anode  152   b  and a second blocky anode  153   b  which are adjacent to each other, or the second auxiliary conductive portion segment  152   a  is disposed between adjacent two third blocky anodes  154   b . The auxiliary conductive portions  15   a  shown in  FIG.  9    have a simple layout structure, and the auxiliary conductive portions  15   a  are evenly distributed on the display panel, so that it is easy to form a uniform capacitive electrode layer on the entire plane parallel to the plane where the substrate  11  is located. 
     Referring to  FIG.  10   ,  FIG.  10    is a top structural view of another display panel according to an embodiment of the present disclosure. The blocky anodes  15   b  may be rectangles shown in  FIG.  9   , or may be rhombuses shown in  FIG.  10   . The rhombic blocky anodes  15   b  may further be disposed in triangles, so that the auxiliary conductive portion  15   a  may include multiple first auxiliary conductive portion segments  151   a  extending along the second direction Y. The first auxiliary conductive portion segments  151   a  are disposed to match the rhombic blocky anodes  15   b  and may be curvilinear as shown in  FIG.  10   , but the curvilinear first auxiliary conductive portion segments  151   a  extend in a same direction. Moreover, in this embodiment, a second auxiliary conductive portion segment  152   a  extending along the first direction X is disposed on an edge of the blocky anode  15   b . The second auxiliary conductive portion segment  152   a  serves as a bus to connect the multiple first auxiliary conductive portion segments  151   a . The auxiliary conductive portions  15   a  shown in  FIG.  10    have a simple layout structure, and the auxiliary conductive portions  15   a  are evenly distributed on the display panel, so that it is easy to form a uniform capacitive electrode layer on the entire plane parallel to the plane where the substrate  11  is located. 
     With continued reference to  FIG.  3   , in an embodiment, the auxiliary conductive portion  15   a  may be a network structure; and a vertical projection of the blocky anode  15   b  on the plane where the substrate  11  is located is located within a mesh of the network structure. The auxiliary conductive portion  15   a  may be disposed in the gap region d 1  around the blocky anodes  15   b  and form a network structure around the blocky anodes  15   b , so that the uniformity of the distribution of the auxiliary conductive portion  15   a  is further improved, and the auxiliary conductive portion  15   a  has a relatively large area directly facing the cathode layer, which is conducive to maintaining the stability of the cathode potential and improving the display efficiency of the display panel. 
     In an embodiment, with continued reference to  FIG.  3   , the anode layer  15 , the organic light-emitting layer  151  and the cathode layer  152  may form a subpixel  153 ; and the display panel may include subpixels  153  of different colors; and on the plane parallel to the plane where the substrate  11  is located, at least part of subpixels  153  of a same color has a same first overlapped area; a first overlapped area of a subpixel  153  is an overlapped area of a jumper portion  131  and an auxiliary conductive portion  15   a  within a same subpixel  153 . 
     As shown in  FIG.  3   , the display panel may include multiple subpixels  153  of different colors. For example, the subpixels  153  may include red subpixels, green subpixels, blue subpixels and the like. For example, among the blocky anodes  15  disposed in a triangle mode provided by the above embodiments, the first blocky anode  152   b , the second blocky anode  153   b , and the third blocky anode  154   b  may be sequentially used as a blocky anode of a red subpixel, a blocky anode of a green subpixel and a blocky anode of a blue subpixel. It can be seen from  FIG.  5    that an overlapped area between a jumper portion  131  corresponding to the part of subpixels and the auxiliary conductive portion  15   a  is S 1 . In this embodiment, the overlapped area between the jumper portion  131  of the subpixel  153  and the corresponding auxiliary conductive portion  15   a  is defined as a first overlapped area, so that in the embodiment, the wiring of the auxiliary conductive portions  15   a  may be arranged to enable that at least part of the subpixels  153  of a same color has a same first overlapped area. Therefore, even if the capacitance between the auxiliary conductive portion  15   a  and the cathode layer  152  has an impact on the emission brightness of the subpixels  153 , for example, the emission brightness of the subpixels  153  is lower than a set value, since the subpixels  153  of a same color has a same overlapped area between the jumper portion  131  and the auxiliary conductive portion  15   a , the capacitance has a same impact on the emission brightness of the subpixels  153  of a same color, and the emission brightness may be compensated by adjusting gamma. In this way, the cathode potential is ensured to be stable, the error of brightness adjustment of the subpixels is reduced, and the color cast of the display picture is effectively avoided. 
     It should be noted that the above embodiments illustrate only the relative positions of the auxiliary conductive portion and the blocky anodes on the plane where the substrate is located, and do not limit the film layer on which the auxiliary conductive portion is disposed. In an embodiment, the auxiliary conductive portion may be disposed in a same layer as the blocky anodes, or may be disposed in a film layer between the blocky anodes and the cathode layer to form a capacitance with the cathode layer. 
     Referring to  FIG.  3   , the auxiliary conductive portion  15   a  may be disposed in the anode layer, that is, the auxiliary conductive portion  15   a  may be disposed in a same layer as the blocky anodes  15   b ; a material of the auxiliary conductive portion  15   a  is at least one of molybdenum or titanium; and a material of the blocky anodes  15   b  is at least one of indium tin oxide or silver. In this embodiment, although the auxiliary conductive portion  15   a  is disposed in a same layer as the blocky anodes  15   b , the metal material of the auxiliary conductive portion  15   a  is different from the metal material of the blocky anodes  15   b . The material of the blocky anodes  15   b  is at least one of indium tin oxide or silver, and the material of the auxiliary conductive portion  15   a  is at least one of molybdenum or titanium. Therefore, two metal etching processes are required in the manufacturing process. In an embodiment, the auxiliary conductive portion  15   a  and the blocky anodes  15   b  may be separately formed by a wet etching process, and the auxiliary conductive portion  15   a  is formed before the blocky anodes  15   b . For example, the blocky anodes  15   b  may be made of an interlayer metal of indium tin oxide, silver and indium tin oxide, and the auxiliary conductive portion  15   a  needs to be made of a metal insensitive to the above etching solution, such as at least one of molybdenum or titanium mentioned above. It should be noted that since the silver material in the blocky anodes  15   b  is easily corroded and oxidized, a metal film layer of molybdenum and titanium is formed first, and then the metal film layer is subjected to wet etching to obtain the structure of the auxiliary conductive portion  15   a ; thereafter, an interlayer metal of indium tin oxide, silver and indium tin oxide may be formed, and then the shape and structure of the blocky anodes  15   b  may be etched by an etching solution. Since the etching solution should not affect the auxiliary conductive portion  15   a , the material of the auxiliary conductive portion  15   a  should be different from the material of the blocky anodes  15   b , so that a metal insensitive to the etching solution, such as molybdenum, titanium mentioned above and the like, is required. In the embodiment, different procedures are adopted for the auxiliary conductive portion  15   a  and the blocky anodes  15   b  through two metal etching processes, so that the size of the auxiliary conductive portion  15   a , such as the line width, and the size of the blocky anodes  15   b  and the like may be adjusted in the separate procedures. For example, the line width of the auxiliary conductive portion  15   a  may be set to be slightly wider, or the area of the blocky anode  15   b  may be set to be relatively large. Through the above two-time metal etching process, the room for the adjustment of the processes of the auxiliary conductive portion  15   a  and the blocky anodes  15   b  is increased, which is conductive to achieving the rational layout of the auxiliary conductive portion  15   a  and the blocky anodes  15   b.    
     With continued reference to  FIG.  3   , the auxiliary conductive portion  15   a  may be disposed in a same layer as the blocky anodes  15   b , and the material of the auxiliary conductive portion  15   a  is the same as the material of the blocky anodes  15   b . In the embodiment, the auxiliary conductive portion  15   a  and the blocky anodes  15   b  may also be manufactured by a same process, and thus the material of the auxiliary conductive portion  15   a  is the same as the material of the blocky anodes  15   b . Exemplarily, at least one of indium tin oxide or silver may be used. In the embodiment, through the process of disposing the auxiliary conductive portion  15   a  and the blocky anodes  15   b  in a same layer, one metal etching process can be saved, the manufacturing process of the display panel can be simplified, and the manufacturing efficiency of the display panel can be improved. As shown in  FIG.  5   , in the embodiment, a distance between an edge of the auxiliary conductive portion  15   a  and an edge of an adjacent blocky anode  15   b  is less than or equal to 5 μm. Due to the setting of the jumper layer  13 , the setting of the connection portions  151   b  of the blocky anodes  15   b  may be greatly reduced, the space of the gap region d 1  is saved, and the width CD 1  of the auxiliary conductive portion  15   a  may be set relatively large than that of a display panel without disposing the jumper layer  13 . In one embodiment, if the distance between adjacent blocky anodes  15   b  is larger than 13 μm, the distance between an edge of the auxiliary conductive portion  15   a  and an edge of an adjacent blocky anode  15   b  is controlled to be less than or equal to 5 μm to prevent a case of a short circuit or an open circuit. Referring to  FIG.  6   , no jumper layer is disposed in  FIG.  6   , so that the width CD 1 ′ of the auxiliary conductive portion  15   a ′ is less than the width CD 1  of the auxiliary conductive portion  15   a . Compared with the comparative example shown in  FIG.  6   , in this embodiment, the width CD 1  of the auxiliary conductive portion  15   a  may be increased to multiple times, so that the difficulty of the manufacturing process of the auxiliary conductive portion  15   a  is reduced, the auxiliary conductive portion  15   a  is prevented from being broken during the manufacturing process, and the reliability of manufacturing the display panel is improved. 
     In addition, the auxiliary conductive portion  15   a  and the blocky anodes  15   b  may be respectively disposed in different film layers.  FIG.  11    is a structural view of another display panel according to an embodiment of the present disclosure. In an embodiment, the display panel may further include a pixel definition layer  17  and a support pole  18 . The pixel definition layer  17  is disposed between the anode layer  15  and the organic light-emitting layer  151 ; the support pole  18  is disposed between the pixel definition layer  17  and the organic light-emitting layer  151 ; and a vertical projection of the support pole  18  on the plane where the substrate  11  is located is located within the pixel definition layer  17 . The auxiliary conductive portion  15   a  is disposed between the pixel definition layer  17  and the support pole  18 ; and the vertical projection of the support pole  18  on the plane where the substrate  11  is located completely overlaps the auxiliary conductive portion  15   a . The auxiliary conductive portion  15   a  is disposed between the pixel definition layer  17  and the support pole  18 , so that the blocky anodes  15   b  and the auxiliary conductive portion  15   a  can be effectively isolated, and mutual impact between signals of the blocky anodes  15   b  and signals of the auxiliary conductive portion  15   a  is avoided. 
     In addition, as shown in  FIG.  12   ,  FIG.  12    is a structural view of another display panel according to an embodiment of the present disclosure. The auxiliary conductive portion  15   a  may further be disposed in a different layer from the blocky anodes  15   b . The auxiliary conductive portion  15   a  may be disposed in a conductive layer on a side of the blocky anodes  15   b  close to the substrate  11 . The blocky anode  15   b  avoids the auxiliary conductive portion  15   a  through the connection portion  131 , so that it is avoided that an overlapped area between the blocky anodes  15   b  and the auxiliary conductive portion  15   a  exits on the plane where the substrate  11  is located and that signals of the blocky anodes  15   b  and signals of the auxiliary conductive portion  15   a  affect each other. 
     Referring to  FIG.  3    and  FIG.  11   , the display panel may further include the pixel definition layer  17  and the support pole  18 . After the anode layer  15  is formed, the pixel definition layer  17  is disposed on a side of the anode layer  15  facing away from the substrate  11 , and the support pole  18  is disposed on a side of the pixel definition layer  17  facing away from the substrate  11 , and a vertical projection of the support pole  18  on the plane where the substrate  11  is located is located within the pixel definition layer  17 . Then, the organic light-emitting layer  151  and the cathode layer  152  are sequentially disposed on a side of the support pole  18  facing from the substrate  11 . As shown in  FIG.  3   , the auxiliary conductive portion  15   a  is disposed in the anode layer  15 , and in the embodiment, the auxiliary conductive portion  15   a  is disposed on a side of the anode layer  15  close to the cathode layer  152 . As shown in  FIG.  11   , the auxiliary conductive portion  15   a  may be disposed between the pixel definition layer  17  and the support pole  18 , and the support pole  18  may completely overlap the auxiliary conductive portion  15   a  to achieve the insulation between the auxiliary conductive portion  15   a  and the cathode layer  152 . In this way, the auxiliary conductive portion  15   a  and the cathode layer  152  form the capacitance to stabilize the cathode potential. Moreover, due to the setting of the jumper layer  13 , the setting of the connection portion  151   b  in the gap region d 1  on the anode layer  15  is greatly reduced, and the auxiliary conductive portion  15   a  overlapping the jumper layer  13  is not disposed in the anode layer  15 , so that the size the blocky anode  15   b  may be appropriately increased according to the size of the gap region d 1 , and increasing the light-emitting area of the entire display panel is increased and the flat display ration of the display panel is increased. 
     In an embodiment, a distance between an edge of the auxiliary conductive portion  15   a  and an edge of the pixel definition layer is less than or equal to 3 μm. Since the auxiliary conductive portion  15   a  is not disposed in the anode layer  15 , the size of the auxiliary conductive portion  15   a  may be set as wide as possible on the premise that the size of the auxiliary conductive portion  15   a  is less than the width of the gap region d 1  between the blocky anodes  15   b . For example, the projection of the auxiliary conductive portion  15   a  may partially overlap the blocky anodes  15   b , so that the area directly facing the blocky anode  15   b  and the cathode layer  152  is increased, the capacitance between the auxiliary conductive portion  15   a  and the cathode layer  152  is increased, and the stability of the potential of the cathode layer  152  is improved. 
     In this embodiment of the present disclosure, at least one jumper layer  13  may be disposed. As shown in  FIG.  3   , one jumper layer  13  may be disposed. In an embodiment, a first jumper layer  13   a  may be disposed between the drive module layer  12  and the first auxiliary layer  14 . A first insulating dielectric layer  161  is disposed on a side of the drive module layer  12  facing away from the substrate  11 ; the first jumper layer  13   a  is disposed on a side of the first insulating dielectric layer  161  facing away from the substrate  11 ; and the first jumper layer  13   a  includes multiple first jumper portions  131   a . The blocky anode  15   b  is connected to a first jumper portion  131   a  corresponding to the blocky anode  15   b  through a first through hole K 1  penetrating through the first auxiliary layer  14 ; and the first jumper portion  131   a  is electrically connected to a drive module  120  corresponding to the first jumper portion  131   a  through a second through hole K 2  penetrating through the first insulating dielectric layer  161 . In this embodiment of the present disclosure, one jumper layer  13  may be disposed. In one embodiment, the first jumper layer  13   a  may be disposed between the drive module layer  12  and the first auxiliary layer  14 . The first insulating dielectric layer  161  is disposed between the first jumper layer  13   a  and the drive module layer  12 . The first jumper layer  13   a  includes multiple first jumper portions  131   a . The blocky anode  15   b  is connected to a first jumper portion  131   a  corresponding to the blocky anode  15   b  through a first through hole K 1  penetrating through the first auxiliary layer  14 ; and the first jumper portion  131   a  is electrically connected to a drive module  120  corresponding to the first jumper portion  131   a  through a second through hole K 2  penetrating through the first insulating dielectric layer  161 . Referring to  FIG.  13   ,  FIG.  13    is a structural view of another comparative example of a display panel according to an embodiment of the present disclosure. In  FIG.  13   , the comparative example is not provided with the jumper layer  13 , and the substrate  11 ′ is sequentially provided with the drive module layer  12 ′, the first auxiliary layer  14 ′, the anode layer  15 ′, the pixel definition layer  17 ′ and the support pole  18 ′. Compared with the display panel in the comparative example, according to the display panel provided in the embodiment, the setting of the connection portions of the blocky anodes in the anode layer  15  can be reduced, which is conducive to disposing the auxiliary conductive portion  15   a  in the gap region between the blocky anodes to form stable capacitance with the cathode layer. Therefore, the display quality of the display panel is improved, and the touch accuracy of the display panel integrated with a touch function is improved. 
       FIG.  14    is a structural view of another display panel according to an embodiment of the present disclosure. In an embodiment, a second jumper layer  13   b  and a third jumper layer  13   c  may be disposed between the drive module layer  12  and the first auxiliary layer  14 .
