Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A display panel, comprising:
a pixel definition layer;
a cathode layer covering the pixel definition layer;
a pillar positioned between the pixel definition layer and the cathode layer; and
a touch function layer disposed on a side of the cathode layer and away from the pixel definition layer, wherein the touch function layer is provided with an electrode trace;
wherein the electrode trace is constructed with a winding structure with a hollow part, and the hollow part corresponds to the pillar to reduce a parasitic capacitance between the cathode layer and the touch function layer at a corresponding position of the pillar;
wherein the display panel further comprises a plurality of sub-pixels; and an orthographic projection of the electrode trace is located between adjacent sub-pixels;
wherein the winding structure is electrically connected to the adjacent electrode trace, the hollow part is provided with a light shielding block insulated from the electrode trace, and a cross-sectional shape of the light shielding block is the same as a cross-sectional shape of the pillar.
