Fig. 1 illustrates a schematic structure of a display panel according to an embodiment of the present application. Fig. 2 is a schematic cross-sectional view of the display panel of fig. 1, taken along line A-A in some embodiments. Fig. 3 shows an exploded schematic view of the display panel of fig. 2.
Referring to fig. 1 to 3, a display panel of an embodiment of the present application includes a substrate 1, a display device 2, and a touch device 3. The substrate 1 includes a display region and a non-display region surrounding the display region, the display region and the non-display region are demarcated by a dotted line S1 in fig. 1, and the dotted line S1 is merely illustrative and does not constitute a structural limitation of the display panel according to the embodiment of the present application.
The display device 2 is disposed in a display area on the substrate 1. The display device 2 is for emitting light and displaying graphics. In some embodiments, the display device 2 includes a light emitting layer 21 and a thin film packaging layer 22 covering the light emitting layer 21, where the thin film packaging layer 22 mainly isolates the light emitting layer 21 from the external environment, so as to prevent intrusion of moisture, harmful gases (oxygen, etc.), dust and rays, prevent damage caused by external force, stabilize various parameters of the device, and further improve the service life of the display panel.
The touch device 3 includes a touch electrode 31, a first touch trace 32 and a second touch trace 33, the touch electrode 31 is disposed in the display area, and the first touch trace 32 and the second touch trace 33 are electrically connected to the touch electrode 31; at least part of the first touch trace 32 and at least part of the second touch trace 33 are disposed in the non-display area.
The touch device 3 is used for realizing a touch function of the display panel, for example, when a user's hand or pen contacts the display panel, a signal from the touch electrode 31 corresponding to the contact position is transmitted to the touch circuit board 6 in the FPC through the first touch trace 32 and the second touch trace 33, and the touch circuit board 6 determines position information of the touch point according to the touch electrode 31. In some embodiments, the touch electrode 31 is formed on a side of the thin film encapsulation layer 22 away from the substrate 1; in other embodiments, the touch electrode 31 may be integrated in the light emitting layer 21.
The inventors have found that signal interference occurs between the first touch trace 32 and the second touch trace 33, thereby affecting the accuracy of touch position detection. Meanwhile, static charges are accumulated in a conduction manner between the first touch trace 32 and the second touch trace 33, and are easily discharged at a place where the impedance of the touch electrode 31 is large, so that the touch electrode is easy to be damaged. The inventors tried to provide a shielding signal line between the first touch trace 32 and the second touch trace 33 to function as a shield. However, with the gradual increase of the requirements for the narrow frame of the display panel, the distance between the touch wires is smaller and smaller, the space for shielding the signal wires is limited, and the shielding effect is poor; in addition, there is a problem in that static charges jump over the shield signal lines to be conducted between the first touch trace 32 and the second touch trace 33.
In view of this, the display panel provided in the embodiment of the application further includes a shielding layer 4, the shielding layer 4 is electrically connected to a fixed potential and insulated from the first touch trace 32 and the second touch trace 33, the shielding layer 4 includes a covering portion 41 and a blocking portion 42, the covering portion 41 is located on a side of the first touch trace 32 away from the substrate 1 and covers the first touch trace 32, and the blocking portion 42 extends from the covering portion 41 toward the substrate 1 and separates the first touch trace 32 and the second touch trace 33. At least part of the partition 42 is located between the first touch trace 32 and the second touch trace 33.
In the first direction parallel to the substrate 1 (i.e., the direction perpendicular to the thickness direction of the substrate 1), the partition portion 42 separates the first touch trace 32 and the second touch trace 33 from each other, so that signal interference between the first touch trace 32 and the second touch trace 33 is avoided, and accuracy of touch position detection is improved. The covering portion 41 covers the first touch trace 32 from the upper side, and can play a role of stopping static charges, so that static charges are prevented from being conducted and accumulated between the first touch trace 32 and the second touch trace 33 by jumping over the partition portion 42, static charges conducted to the display device 2 are reduced, and the risk of static discharge is reduced. The shielding layer 4 is electrically connected to a fixed potential, and the electrostatic charges on the first touch trace 32 and the electrostatic charges on the second touch trace 33 can be led out to the outside through the shielding layer 4, so that the static electricity is effectively dredged, and the risk of static electricity discharge is reduced.
In addition, the shielding layer4 obtains a fixed potential, so that the interference of the external interference source to the first touch trace 32 is shielded, the first touch trace 32 cannot respond due to the change of the external voltage, and the touch precision is improved.
In some embodiments, the partition 42 includes a first sub-partition 421 and a second sub-partition 422 extending from the cover 41, the first sub-partition 421 being located between the first touch trace 32 and the second touch trace 33, the second sub-partition 422 being located on a side of the first touch trace 32 remote from the first sub-partition 421. At this time, the first sub-partition portion 421 and the second sub-partition portion 422 can surround the first touch trace 32 from two sides, and the covering portion 41 covers the first touch trace 32 from an upper side, so that interference of the first touch trace 32 to signal lines nearby the first touch trace 32 can be effectively reduced, static charges on the first touch trace 32 are prevented from diffusing to the periphery, and the risk of static discharge is reduced.

In some embodiments, the touch sensing electrodes 311 are plural and extend along the longitudinal direction, and the plural touch sensing electrodes 311 are arranged at intervals along the transverse direction; the touch driving electrodes 312 are plural and extend in a lateral direction, and the plural touch driving electrodes 312 are arranged at intervals in a longitudinal direction. Alternatively, the touch sensing electrode 311 and the touch driving electrode 312 are arranged in the same layer, that is, the touch electrode 31 has a single layer structure, and overlapping portions of the touch sensing electrode 311 and the touch driving electrode 312 are overlapped through bridge insulation. The touch sensing electrode 311 and the touch driving electrode 312 share the same Mask, and the number of film layers of the display panel is not increased, and the number of masks in the process is not increased.

In some embodiments, the fixed potential is a ground potential. The shielding layer 4 is connected to the ground potential, so that static charges of the first touch trace 32 and static charges of the second touch trace 33 can be quickly led out to the outside, and the risk of static discharge is reduced.
