The particular implementation modes of the display panel and the display device according to the embodiments of the present disclosure are described in detail below in combination with the accompanying drawings. A thickness and a shape of each film layer in the accompanying drawings do not reflect true proportions, and are merely illustrative of contents of the present disclosure.

FIG.1is a schematic planar structural diagram of a display panel according to an embodiment of the present disclosure. As shown inFIG.1, the display panel according to the embodiment of the present disclosure may include: a display area A and a peripheral area C positioned on at least one side of the display area A.FIG.2is an enlarged schematic diagram of the peripheral area C inFIG.1.FIG.3is an enlarged schematic diagram at dashed box01inFIG.2. With reference toFIGS.1-3, the above peripheral area C may include: a first fan-out area F1, a second fan-out area F2positioned on one side, away from the display area A, of the first fan-out area F1, and a bendable area B positioned between the first fan-out area F1and the second fan-out area F2.

FIG.4is an enlarged schematic diagram at dashed box Q2inFIG.3.FIG.5is another schematic planer structural diagram of the display panel according to the embodiment of the present disclosure. With reference toFIGS.3-5, the display panel according to the embodiment of the present disclosure may further include:a substrate10;a plurality of touch electrodes11, at least some of which are positioned on a portion, in the display area A, of the substrate10; during specific implementation, most of the touch electrodes11in the display panel are positioned inside the display area A; in order to ensure a touch effect at an edge of the display area A, there are some touch electrodes11beyond the edge of the display area A at the edge; certainly, in some display panels having low requirements on the touch effect, each touch electrode11may also be positioned inside the display area A, which will not be limited herein;a plurality of touch leads12positioned on the substrate10, one ends of the touch leads12being coupled to the touch electrodes11, the other ends thereof being positioned in the peripheral area C, the plurality of touch leads12in the display panel being divided into a plurality of touch lead sets12M, and the touch lead set12M including the plurality of touch leads12;a plurality of data leads13positioned on a portion, in the peripheral area C, of the substrate10, the plurality of data leads13in the display panel being divided into a plurality of data lead sets13M, the data lead set13M including a plurality of data leads13, and at least some of the touch lead sets12M and some of the data lead sets13M in the display panel being alternately distributed; andat least one shielding line14positioned on the portion, in the peripheral area C, of the substrate10, an orthographic projection, on the substrate10, of the shielding line14being positioned between an orthographic projection, on the substrate10, of the touch lead12and an orthographic projection, on the substrate10, of the data lead13.

In the display panel according to the embodiment of the present disclosure, at least one shielding line is arranged, and the orthographic projection, on the substrate, of the shielding line is positioned between the orthographic projection, on the substrate, of the touch lead and the orthographic projection, on the substrate, of the data lead. Therefore, an electric field generated by the touch leads can be shielded, and coupling capacitance is prevented from being formed between the touch leads and the data leads. Accordingly, mutual interference between touch signals and data signals is relieved, thereby improving a display effect and a touch effect of the display panel.

In practical application, the shielding line may be configured to be positioned on the same film layer as the touch leads or the data leads. Alternatively, the shielding line is positioned on a film layer between the touch leads and the data leads. Since the electric field generated by the touch leads is radial, the shielding line is arranged in this way, so as to effectively shield the electric field generated by the touch leads. Accordingly, the mutual interference between the touch signals and the data signals is relieved.

With the touch electrodes11as self-capacitance electrodes as an example illustrated inFIG.5, during specific implementation, the touch electrodes11may also be mutual capacitance electrodes, which will not be limited herein. As shown inFIG.5, at least some of the touch electrodes11in the display panel are distributed in the display area A, and the touch signals are transmitted through the touch leads12.

As shown inFIGS.2and3, one ends of the touch leads are coupled to the touch electrodes in the display area, and the other ends thereof pass through the first fan-out area F1, the bendable area B, and the second fan-out area F2, so as to be coupled to an integrated drive chip IC. The integrated drive chip IC may be a touch display driver integration (TDDI) chip. With the touch leads being coupled to the integrated drive chip IC as an example illustrated inFIG.2, during specific implementation, the touch leads may also be coupled to the drive chip through a flexible printed circuit (FPC). A connection mode of the touch leads will not be limited herein.

With reference toFIGS.2and3continuously, the display area A of the display panel is provided with a plurality of sub-pixels arranged in an array. A plurality of data lines are arranged in the display area A. The data lines are typically coupled to one column of sub-pixels. The data lines have the same extension directions as the touch leads. The data lines are coupled to the data leads. The data leads pass through the first fan-out area F1, the bendable area B, and the second fan-out area F2, so as to be coupled to the integrated drive chip IC. In the first fan-out area F1, the bendable area B, and the second fan-out area F2, the touch leads and the data leads are distributed in groups. That is, the plurality of touch leads in the display panel are divided into the plurality of touch lead sets12M, and the plurality of data leads in the display panel are divided into the plurality of data lead sets13M. In this way, the touch signals and the data signals are led out conveniently.

In some areas, close to the display area A, of the peripheral area C, due to the limitation of a routing space, in a direction perpendicular to the substrate10, the touch lead sets12M may partially overlap the data lead sets13M. Therefore, in the embodiment of the present disclosure, at least some of the touch lead sets12M and some of the data lead sets13M in the display panel are alternately distributed. Certainly, when there is a sufficient routing space, all the touch lead sets12M and all the data lead sets13M in the display panel may be alternately distributed, which will not be limited herein.

In addition, the shielding line may be configured to be positioned in at least one of the first fan-out area, the bendable area, and the second fan-out area. With reference toFIGS.2and3continuously, since the integrated drive chip IC is small-sized, in order to couple the plurality of touch leads and the plurality of data leads to a position of the integrated drive chip IC, the first fan-out area F1and the second fan-out area F2are configured to be of a fan shape in which a side edge close to the display area A has a greater width than a side edge away from the display area A. Moreover, at least in the second fan-out area F2, the touch leads and the data leads are each provided with an inclined section inclined towards the integrated drive chip IC. In the first fan-out area F1, the bendable area B, and the second fan-out area F2, a distance between the touch lead and the data lead that are adjacent to each other is small. Therefore, the shielding line is arranged in at least one of the first fan-out area F1, the bendable area B, and the second fan-out area F2. Accordingly, coupling capacitance formed between the touch leads and the data leads can be effectively shielded, thereby greatly reducing the mutual interference between the touch signals and the data signals.

As shown inFIG.2, in order to provide power supply signals for sub-pixels in the display area A, the above display panel may further include: a high-level power supply voltage signal line VDD in a non-display area, and a low-level power supply voltage signal line VSS. Moreover, the high-level power supply voltage signal line VDD and the low-level power supply voltage signal line VSS are coupled to the flexible printed circuit (FPC).

With reference toFIGS.2and3, in the above display panel according to some embodiments of the present disclosure, the first fan-out area F1, the bendable area B, and the second fan-out area F2are arranged. After the display panel is manufactured, the display panel may be bent at a position of the bendable area B, so as to bend the second fan-out area F2of the display panel to one side, facing away from a display surface, of the display panel. Therefore, the signal lines such as the touch leads and the data leads in the second fan-out area F2are coupled to the integrated drive chip IC on one side, facing away from the display surface, of the display area. Accordingly, a frame area of the display panel is greatly narrowed.

In practical application, in the above display panel according to the embodiment of the present disclosure, as shown inFIG.4, the shielding line14is positioned in the first fan-out area F1, the bendable area B, and the second fan-out area F2.

The shielding line14may have the same shape as the data leads13positioned in the first fan-out area F1, the bendable area B, and the second fan-out area F2.

In the first fan-out area F1, the bendable area B, and the second fan-out area F2, the distance between the touch lead12and the data lead13that are adjacent to each other is small. Therefore, the shielding line14is arranged in the first fan-out area F1, the bendable area B, and the second fan-out area F2. Therefore, the coupling capacitance formed between the touch leads12and the data leads13can be more effectively shielded, thereby greatly reducing the mutual interference between the touch signals and the data signals. Moreover, the shielding line14is configured to have the shape as the data leads13positioned in the first fan-out area F1, the bendable area B, and the second fan-out area F2. Therefore, the routing space between the touch leads12and the data leads13can be fully utilized, and the shielding line14has a sufficient length, so as to ensure that the shielding line14has an excellent shielding effect.

FIG.6is a schematic sectional view of the display panel in the display area according to the embodiment of the present disclosure. As shown inFIG.6, the above display panel in the embodiment of the present disclosure may further include: a plurality of first electrodes151, second electrodes152positioned on one sides, facing away from the substrate10, of the first electrodes151, and light-emitting layers153positioned between the first electrodes151and the second electrodes152. The second electrodes152may be arranged on an entire surface. A pixel definition layer17may further be arranged between a film layer on which the first electrode151is positioned and the light-emitting layer153. The pixel definition layer17is configured to define an area of each sub-pixel. That is, a position at which an opening of the pixel definition layer17is positioned in the figure corresponds to one sub-pixel.

In addition, in order to drive each sub-pixel to emit light, the above display panel may further include: a thin film transistor (TFT), a capacitor structure, etc. The thin film transistor (TFT) may include: an active layer Ac, an input end S, an output end D, and a gate Ga1. The output end D of the thin film transistor (TFT) is coupled to the first electrode151through a conductive connector LB, and the gate Ga1and a third electrode Ga2constitutes the capacitor structure. In order to insulate conductive components of different film layers from one another, the above display panel may further include: a first gate insulation layer GI1positioned between the active layer Ac and the gate Ga1, a second gate insulation layer GI2positioned between the gate Ga1and the third electrode Ga2, an interlayer insulation layer ILD positioned between the third electrode Ga2and the input end S, a first planarization layer PLN1positioned between the input end S and the conductive connector LB, and a second planarization layer PLN2positioned between the conductive connector LB and the first electrode151.

With reference toFIGS.4-6, in the embodiment of the present disclosure, the orthographic projection, on the substrate10, of the shielding line14overlaps an orthographic projection, on the substrate10, of the second electrode152. It can be seen fromFIG.4that a certain space still exists between the touch lead12and the data lead13at an edge, close to the first fan-out area F1, of an area covered with the second electrode152. Therefore, the shielding line14extends to the area covered with the second electrode152, thereby further enhancing the shielding effect of the shielding line14. In addition, as shown inFIG.5, the orthographic projection, on the substrate10, of the shielding line14does not overlap the orthographic projection, on the substrate10, of the touch electrode11. Accordingly, the situation that the shielding line14is connected to the touch electrode11in a shorted manner, thereby affecting the touch effect of the touch electrode11can be avoided.

During specific implementation, as shown inFIG.6, the above display panel according to the embodiment of the present disclosure may further include: an encapsulation layer16positioned on one side, facing away from the substrate10, of the second electrode152, a touch electrode layer TP positioned on one side, facing away from the substrate10, of the encapsulation layer16, and a touch barrier layer18positioned between the encapsulation layer16and the touch electrode layer TP. The encapsulation layer16may include: organic film layers162and inorganic film layers161that are laminated. The inorganic film layers161can block water vapor and oxygen. The organic film layers162can be positioned between two adjacent inorganic film layers161and release stress and perform planarization. The touch electrode in the embodiment of the present disclosure is positioned in the touch electrode layer TP.

FIG.7is a schematic sectional view along dashed line L1inFIG.4. With reference toFIGS.4,6, and7, the above shielding line14may include: a first shielding sub-line141and a second shielding sub-line142.

The first shielding sub-line141is positioned on one side, facing away from the substrate10, of the encapsulation layer16.

The second shielding sub-line142is positioned on one side, close to the substrate10, of the first electrode151.

An orthographic projection, on the substrate10, of a first end of the first shielding sub-line141is positioned within a range of the orthographic projection, on the substrate, of the second electrode152. A second end of the first shielding sub-line141is positioned in the first fan-out area F1. The second shielding sub-line142is positioned in the first fan-out area F1, the bendable area B, and the second fan-out area F2.

The second end of the first shielding sub-line141is coupled to the second shielding sub-line142through a first via hole U1, the first via hole U1penetrating an insulation layer between the first shielding sub-line141and the second shielding sub-line142.

Since the second electrodes152are typically arranged on the entire surface, in order to prevent the touch signals from being shielded by the second electrodes152, the touch electrode layer TP is arranged on one side, facing away from the substrate10, of the encapsulation layer16. Therefore, in order to effectively relieve the mutual interference between the touch leads12and the data leads13, the first shielding sub-line141is arranged on one side, facing away from the substrate10, of the encapsulation layer16. Moreover, in order to prevent the shielding line14from being broken at the bendable area B when the display panel is bent at the bendable area B, in the embodiment of the present disclosure, the shielding line14is configured as the first shielding sub-line141and the second shielding sub-line142. The second shielding sub-line142is positioned on one side, close to the substrate10, of the first electrode151. The second end of the first shielding sub-line141is coupled to the second shielding sub-line142through the first via hole U1positioned in the first fan-out area F1. Therefore, the first shielding sub-line141is switched to the second shielding sub-line142in the first fan-out area F1. The shielding line14undergoes small stress when being bent at the bendable area B. Accordingly, the shielding line14is unlikely to be broken at the bendable area B.

During specific implementation, in the above display panel according to embodiments of the present disclosure, with reference toFIGS.4,6, and7, the touch lead12may include: a first lead portion12aand a second lead portion12b.

The first lead portion12ais positioned on one side, facing away from the substrate10, of the encapsulation layer16. That is, the first lead portion12ais positioned on the touch electrode layer TP. In addition, the touch electrodes are further arranged on the touch electrode layer TP.

The second lead portion12bis positioned on one side, close to the substrate10, of the first electrode151.

A first end of the first lead portion12ais coupled to the touch electrode, and a second end thereof is positioned in the first fan-out area F1. The second lead portion12bis positioned in the first fan-out area F1, the bendable area B, and the second fan-out area F2.

A second end of the first lead portion12ais coupled to the second lead portion12bthrough a first through hole V1, the first through hole V1penetrating an insulation layer between the first lead portion12aand the second lead portion12b.

The second shielding sub-line142is positioned on the same film layer as the second lead portion12b.

The second electrodes152arranged in the entire surface are typically arranged in the display area of the display panel. In order to prevent the touch signals from being shielded by the second electrodes152, the touch electrode layer TP is arranged on one side, facing away from the substrate10, of the encapsulation layer16. In order to prevent the touch lead12from being broken at the bendable area B when the display panel is bent at the bendable area B, in the embodiment of the present disclosure, the touch lead12is configured to include the first lead portion12aand the second lead portion12b. One end of the first lead portion12ais coupled to the touch electrode in the touch electrode layer TP, and the other end thereof extends into the first fan-out area F1and is coupled to the second lead portion12bthrough the first through hole V1. Therefore, the touch lead12is switched to the second lead portion12bat the first fan-out area F1. The touch lead12undergoes small stress when being bent at the bendable area B. Accordingly, the touch lead12is unlikely to be broken at the bendable area B.

In addition, the second shielding sub-line142is positioned on the same film layer as the second lead portion12b. In a manufacturing process, the second shielding sub-line142and the second lead portion12bmay be manufactured through the same composition process, thereby reducing a manufacturing cost. Moreover, the second lead portion12bmay be positioned on the same film layer as the conductive connector LB in the display area. Therefore, the conductive connector LB, the second shielding sub-line142, and the second lead portion12bmay be manufactured through the same composition process, thereby further reducing the manufacturing cost.

FIG.8is a schematic sectional view along dashed line L2inFIG.4. As shown inFIG.8, the first shielding sub-line141includes: a first wire1411and a second wire1412positioned on one side, close to the substrate10, of the first wire1411. The first wire1411is coupled to the second wire1412through a second through hole V2, the second through hole V2penetrating an insulation layer19between the first wire1411and the second wire1412.

The first lead portion12aincludes: a first lead12a1and a second lead12a2positioned on one side, close to the substrate10, of the first lead12a1. The first lead12a1is coupled to the second lead12a2through a third through hole V3, the third through hole V3penetrating an insulation layer19between the first lead12a1and the second lead12a2.

The first wire1411is positioned on the same film layer as the first lead12a1. The second wire is positioned on the same film layer as the second lead.

During specific implementation, the touch electrode in the touch electrode layer may also include: a first touch sub-electrode and a second touch sub-electrode that are laminated. The first touch sub-electrode is coupled to the second touch sub-electrode through a through hole. In a manufacturing process, the first touch sub-electrode, the first wire, and the first lead may be manufactured through the same composition process. The second touch sub-electrode, the second wire, and the second lead may be manufactured through the same composition process, thereby reducing the manufacturing cost.

Alternatively,FIG.9is a schematic sectional view along dashed line L3inFIG.4. As shown inFIGS.4and9, in the above display panel provided in the embodiment of the present disclosure, the above shielding line14may further include: a third shielding sub-line143positioned in the second fan-out area F2.

The third shielding sub-line143is positioned on one side, close to the substrate10, of the second shielding sub-line142.

The second shielding sub-line142is coupled to the third shielding sub-line143through a second via hole U2. The second via hole U2penetrates an insulation layer between the second shielding sub-line142and the third shielding sub-line143. The second via hole U2is positioned in the second fan-out area F2.

Since the electric field generated by the touch leads is radial, double-layer wires arranged in a laminated manner are employed as the shielding line14. Both the second shielding sub-line142and the third shielding sub-line143play a role in shielding. Therefore, the shielding performance of the shielding line14can be improved, and a range capable of being shielded by the shielding line14can be wider, thereby further reducing the mutual interference between the touch signals and the data signals. Moreover, the second shielding sub-line142is coupled to the third shielding sub-line143through the second via hole U2. Therefore, a better shielding effect can be realized compared with two shielding sub-lines separately arranged. In addition, the second via hole U2is provided in an area outside the bendable area B. Therefore, the display panel can be prevented from being broken, etc. when being bent at the bendable area B.

FIG.10is another schematic sectional view along dashed line L3inFIG.4. As shown inFIGS.4and10, in the above display panel according to the embodiment of the present disclosure, the shielding line14may further include: a fourth shielding sub-line144positioned in the second fan-out area F2.

The fourth shielding sub-line144is positioned on one side, close to the substrate10, of the third shielding sub-line143.

The third shielding sub-line143is coupled to the fourth shielding sub-line144through a third via hole U3. The third via hole U3penetrates an insulation layer between the third shielding sub-line143and the fourth shielding sub-line144.

Since the electric field generated by the touch leads is radial, the fourth shielding sub-line144is arranged on one side, close to the substrate10, of the third shielding sub-line143. The fourth shielding sub-line144is coupled to the third shielding sub-line143through the third via hole U3. The second shielding sub-line142, the third shielding sub-line143, and the fourth shielding sub-line144all play a role in shielding. Therefore, the shielding performance of the shielding line14is further improved, thereby further reducing the mutual interference between the touch signals and the data signals.

It should be noted that with the second shielding sub-line142being coupled to the third shielding sub-line143through one second via hole U2as an example illustrated in the accompanying drawing in the embodiment of the present disclosure, during specific implementation, in order to enhance the conduction performance of the second shielding sub-line142and the third shielding sub-line143, the second shielding sub-line142may also be coupled to the third shielding sub-line143through more second via holes U2. Similarly, the third shielding sub-line143may also be coupled to the fourth shielding sub-line144through more third via holes U3.

Alternatively, in the above display panel according to the embodiment of the present disclosure, as shown inFIG.10, in the peripheral area, the plurality of data leads in the display panel may be divided into: a plurality of first data leads13apositioned on a first metal layer, and a plurality of second data leads13bpositioned on a second metal layer. The second metal layer is positioned on one side, close to the substrate, of the first metal layer.

Orthographic projections, on the substrate10, of the first data leads13aand orthographic projections, on the substrate10, of the second data leads13bare alternately distributed.

In some embodiments of the present disclosure, the plurality of data leads positioned in the peripheral area are divided into the plurality of first data leads13aand the plurality of second data leads13b. The first data leads13aand the second data leads13bare positioned on different metal layers, and the first data leads13aand the second data leads13bare alternately distributed. In this way, adjacent data leads are positioned on different metal layers. Therefore, mutual interference between the adjacent data leads can be avoided, the display effect of the display panel can be improved, and an overall routing width can be reduced, thereby facilitating the design of a narrow frame. With reference toFIGS.6and10, the first metal layer may be a film layer on which the third electrode Ga2is positioned. That is, the first data leads13amay be positioned on the same film layer as the third electrode Ga2. The second metal layer may be a film layer on which the gate Ga1is positioned. That is, the second data leads13bmay be positioned on the same film layer as the gate Ga1. In the manufacturing process, the first data lead13aand the third electrode Ga2may be manufactured through the same composition process. The second data lead13band the gate Ga1may be manufactured through the same composition process, thereby reducing the manufacturing cost.

In addition, the data leads are coupled to the data lines in the display area. The data lines in the display area may be positioned on the same film layer as the input end S of the thin film transistor (TFT). In the manufacturing process, the input end S and the output end D of the thin film transistor (TFT) and the data lines may be manufactured through the same composition process, thereby reducing the manufacturing cost.

During specific implementation, in the above display panel according to some embodiments of the present disclosure, as shown inFIG.10, the fourth shielding sub-line144may be arranged on the same layer as the first data leads13a.

FIG.11is yet another schematic sectional view along dashed line L3inFIG.4. As shown inFIG.11, the fourth shielding sub-line144may be arranged on the same layer as the second data leads13b.

FIG.12is still another schematic sectional view along dashed line L3inFIG.4. As shown inFIG.12, the fourth shielding sub-line144is arranged on the same layer as the first data leads13a. Moreover, the fourth shielding sub-line144is arranged on the same layer as the second data leads13b. That is, some of the plurality of fourth shielding sub-lines144are arranged on the same layer as the first data leads13a, and the other fourth shielding sub-lines144are arranged on the same layer as the second data leads13b.

In conclusion, the fourth shielding sub-lines144are arranged in the three above modes. The fourth shielding sub-lines144and the first data leads13aor the second data leads13bmay be manufactured through the same composition process, thereby reducing the manufacturing cost.

FIG.13is an enlarged schematic diagram at dashed box Q3inFIG.3. As shown inFIGS.3and13, the above display panel according to the embodiment of the present disclosure may further include: a test signal line20arranged on the same layer as the third shielding sub-line143and positioned in the second fan-out area F2.

An extension direction of the test signal line20intersects with an extension direction of the third shielding sub-line143.

The orthographic projection, on the substrate, of the third shielding sub-line143does not overlap an orthographic projection, on the substrate, of the test signal line20.

In this way, the situation that the third shielding sub-line143intersects with the test signal line20, thereby affecting a test effect of the test signal line20can be avoided.

FIG.14is a schematic sectional view at dashed box Q4inFIG.3. As shown inFIGS.3and14, in the above display panel according to the embodiment of the present disclosure, the shielding line14is positioned in a gap between the touch lead set12M and the data lead set13M.

The plurality of touch leads and the plurality of data leads in the display panel are distributed in groups. Therefore, the shielding line14is arranged in the gap between the touch lead set12M and the data lead set13M. Accordingly, the coupling capacitance between the touch leads and the data leads can be effectively shielded, and the mutual interference between the touch signals and the data signals is small.

Alternatively, with reference toFIG.14continuously, the above display panel according to the embodiment of the present disclosure includes a plurality of shielding lines. The plurality of shielding lines in the display panel may include a plurality of ground lines14b. At least one ground line14bis arranged in a gap between the touch lead set12M and the data lead set13M that are adjacent to each other. In a drive process, fixed potential signals, such as ground signals, may be applied to the ground lines14b, so as to improve a shielding effect of suspended touch leads14aand the ground lines14b.

In addition, the plurality of shielding lines in the above display panel may further include: a plurality of suspended touch leads14a. At least one suspended touch lead14ais arranged in the gap between the touch lead set12M and the data lead set13M that are adjacent to each other. The suspended touch lead14ais positioned between the ground line14band the touch lead set12M. In an actual drive process, the touch signals may be applied to the suspended touch leads14a. For example, the touch signals applied to the suspended touch leads14amay be the same signals as in the touch leads12. Therefore, the suspended touch lines14aare arranged on two sides of the touch lead set12M, so as to apply the touch signals to both each touch lead12in the touch lead set12M and the suspended touch lines14a.

In some embodiments of the present disclosure, with two suspended touch leads14aand two ground lines14bbeing arranged in the gap between the touch lead set12M and the data lead set13M that are adjacent to each other as an example illustrated inFIG.14, the number of the suspended touch leads14aand the ground lines14bis not limited herein. During specific implementation, the number of the suspended touch leads14aand the ground lines14bis rationally configured according to a size of the gap between the touch lead set12M and the data lead set13M that are adjacent to each other.

FIG.15is yet another schematic planer structural diagram of the display panel according to the embodiment of the present disclosure. As shown inFIG.15, the above display panel according to the embodiment of the present disclosure may further include: a touch shielding line (as shown as211or212inFIG.15) positioned on the substrate10.

The peripheral areas include: a first peripheral area C1and a second peripheral area C2that are arranged opposite each other, and a third peripheral area C3and a fourth peripheral area C4that are arranged opposite each other. The shielding line14is positioned in the first peripheral area C1.

A first end211a(or212a) and a second end211b(or212b) of the touch shielding line211(or212) are positioned in the first peripheral area C1. The touch shielding line211(or212) passes through the second peripheral area C2, the third peripheral area C3, and the fourth peripheral area C4. The touch shielding line211(or212) surrounds each touch electrode11in the display panel.

In this way, an influence from external interference on the touch electrodes11can be shielded through the touch shielding line211(or212) surrounding each touch electrode11in the display panel, thereby improving the touch effect of the display panel.

During specific implementation, in the above display panel according to some embodiments of the present disclosure, with reference toFIG.15continuously, the touch shielding lines in the display panel include: a first touch shielding line211and a second touch shielding line212. The second touch shielding line212is positioned on one side, close to the touch electrode11, of the first touch shielding line211. In the embodiment of the present disclosure, two touch shielding lines, that is, the first touch shielding line211and the second touch shielding line212are arranged. In practical application, different signals may be applied to the first touch shielding line211and the second touch shielding line212. Therefore, the shielding effect is improved, and the influence from the external interference on the touch electrode11is further shielded.

Alternatively, in the above display panel according to some embodiments of the present disclosure, as shown inFIG.15, the first touch shielding line211may include: a first touch shielding sub-line2111, and at least two second touch shielding sub-lines2112.

The first touch shielding sub-line2111is positioned in the second peripheral area C2, the third peripheral area C3, and the fourth peripheral area C4. The second touch shielding sub-line2112is coupled to the first touch shielding sub-line2111, and the second touch shielding sub-line2112is positioned in the first peripheral area C1.

That is, the first touch shielding line211is a signal line (that is, the first touch shielding sub-line2111) in the second peripheral area C2, the third peripheral area C3, and the fourth peripheral area C4. The first touch shielding line211extends to the first peripheral area C1and then is divided into at least two signal lines (that is, the second touch shielding sub-lines2112). With the first touch shielding line211including three second touch shielding sub-lines2112as an example illustrated inFIG.15, during specific implementation, the first touch shielding line may be configured as actually required.

In this way, the first touch shielding line211is provided with at least two first ends211aand at least two second ends211b, thereby facilitating coupling to pins of other components. In the drive process, a fixed signal, such as a ground signal, may be applied to the first touch shielding line211. A touch signal may be applied to the second touch shielding line212. Therefore, an excellent shielding effect is realized.

In practical application, in the above display panel according to some embodiments of the present disclosure, as shown inFIG.15, in the second peripheral area C2, the third peripheral area C3, and the fourth peripheral area C4, the first touch shielding line211has a greater line width than the second touch shielding line212. That is, the greater the distance from the touch electrode11is, the greater the line width of the touch shielding line is. Therefore, the shielding effect of the touch shielding line on external interference can be improved, and the touch effect of the display panel is improved.

On the basis of the same inventive concept, a display device is further provided in an embodiment of the present disclosure. The display device includes any one of the above display panels. The display device may be applied to any product or component having a display function such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, and a navigator. The principles of the display device to solve the problem are similar to those of the above display panel. Therefore, reference may be made to implementation of the above display panel for implementation the display device, and the repetitions will not be repeated.

The display device according to some embodiments of the present disclosure may further include an integrated drive chip.

All touch leads, all data leads, and all shielding lines in the display panel are coupled to the integrated drive chip.

The display panel is bent at a bendable area. A second fan-out area of the display panel and the integrated drive chip are positioned on one side, facing away from a display surface, of the display panel.

During specific implementation, after being manufactured, the display panel may be bent at a position of the bendable area, so as to bend the second fan-out area of the display panel to one side, facing away from the display surface, of the display panel. Therefore, signal lines such as touch leads and data leads in the second fan-out area are coupled to the integrated drive chip on one side, facing away from the display surface, of the display area, thereby greatly narrowing a frame area of the display panel.

In the display panel and the display device according to embodiments of the present disclosure, at least one shielding line is arranged, and the orthographic projection, on the substrate, of the shielding line is positioned between the orthographic projection, on the substrate, of the touch leads and the orthographic projection, on the substrate, of the data lead. Therefore, the electric field generated by the touch leads can be shielded, and coupling capacitance can be prevented from being formed between the touch leads and the data leads. Accordingly, the mutual interference between the touch signals and the data signals is relieved, thereby further improving the display effect and the touch effect of the display panel.
