The display panel comprises a display area, the display area comprises a camera area and a peripheral area surrounding the camera area, the camera area is provided with a transparent first touch control structure, and the first touch control structure is arranged between a substrate and an organic luminescent layer.

First claim

The invention claimed is:

1. A display panel, comprising a display area, wherein the display area comprises a camera area and a peripheral area surrounding the camera area,
the camera area is provided with a transparent first touch control structure, and the first touch control structure is arranged between a substrate and an organic luminescent layer in a direction perpendicular to the substrate;
wherein the peripheral area is provided with a second touch control structure, and the second touch control structure is located on the side, away from the organic luminescent layer, of a thin film encapsulation layer and is electrically connected with the first touch control structure;
wherein the first touch control structure comprises a plurality of first wires and a plurality of second wires,
the first wires and the second wires are insulated from each other, and
the first wires are electrically connected with the second touch control structure, or the second wires are electrically connected with the second touch control structure;
wherein jumper wires are further provided, one end of a jumper wire is electrically connected with the second touch control structure, and the other end of the jumper wire is electrically connected with the first wires or the second wires.

2. The display panel according to claim 1 , wherein a first wire and a second wire each comprise a plurality of electrode blocks, and in a direction parallel to the substrate, the shapes of the electrode blocks include at least one of the following: square and rhombus.

3. The display panel according to claim 2 , wherein a first wire comprises a bridging wire, one end of the bridging wire is connected with one electrode block of the first wire, and the other end of the bridging wire is connected with another electrode block of an adjacent first wire; or
a second wire comprises a bridging wire, one end of the bridging wire is connected with one electrode block of the second wire, and the other end of the bridging wire is connected with another electrode block of an adjacent second wire;
and the electrode blocks of the first wires and the electrode blocks of the second wires are arranged on the same layer.

4. The display panel according to claim 1 , wherein a pixel defining structure is disposed between the organic luminescent layer and the first touch control structure, and the pixel defining structure covers the first wires and the second wires;
and in a direction parallel to the substrate, the pixel defining structure is at least partially filled between the first wires and the second wires.

5. The display panel according to claim 1 , wherein the second touch control structure comprises first touch wires and second touch wires, and the first touch wires and the second touch wires are arranged along the areas between sub-pixels of the organic luminescent layer in a direction perpendicular to the substrate.

6. The display panel according to claim 5 , wherein under the condition that the first wires are transmitting electrodes of the first touch control structure and the first touch wires are transmitting electrodes of the second touch control structure, the first wires are electrically connected with the first touch wires.

7. The display panel according to claim 1 , wherein a planarization layer is disposed between the substrate and the organic luminescent layer, and the first touch control structure is located on the side, away from the substrate, of the planarization layer.

8. A display equipment, comprising the display panel according to claim 1 .
