Abstract
A display panel, a manufacturing method of the display panel, and a display device are provided. The display panel includes an under-screen device area and a non-under-screen device area, wherein an area under the under-screen device area includes an area where hardware is installed; the under-screen device area includes a substrate portion, an anode layer, a pixel definition layer, a deformation layer, a cathode layer, and an encapsulation layer; wherein, a volume of the deformation layer expands under a first predetermined condition to enable a thickness of the cathode layer in the under-screen device area less than a thickness of the cathode layer in the non-under-screen device area.
Claims10
A display panel, comprising:
- an under-screen device area and a non-under-screen device area, wherein an area under the under-screen device area comprises an area where hardware is installed;
- the under-screen device area comprises a substrate portion, an anode layer, a pixel definition layer, a deformation layer, a cathode layer, and an encapsulation layer sequentially disposed on the substrate portion;
- wherein a volume of the deformation layer expands under a first predetermined condition to enable a thickness of the cathode layer in the under-screen device area to be less than a thickness of the cathode layer in the non-under-screen device area.
A method of manufacturing a display panel, comprising:
- dividing the display panel into an under-screen device area and a non-under-screen device area;
- wherein the under-screen device area corresponds to an area under which hardware is installed;
- providing a substrate;
- forming an anode layer above the substrate;
- forming an organic layer and a pixel definition layer above the anode layer;
- and
- forming a deformation layer above the pixel definition layer in the under-screen device area;
- wherein when forming a cathode layer, a volume of the deformation layer is expanded by a first predetermined condition to enable a thickness of the cathode layer positioned above the deformation layer less than a thickness of the cathode layer in the non-under-screen device area.
