Abstract
An OLED display panel and a fabrication method of the OLED display panel are provided. The OLED display panel includes a substrate, a planarization layer, a pixel definition layer, a cover plate, a first encapsulation part, and a second encapsulation part. The substrate includes a display area and a frame area. The pixel definition layer is provided with the first protrusion in the frame area, and at least a portion of the first protrusion is covered by the first encapsulation part.
Claims18
An OLED display panel including a pixel definition layer having protrusions, comprising:
- a substrate, wherein the substrate comprises a display area and a frame area arranged on a periphery of the display area;
- a planarization layer, wherein the planarization layer is provided on the substrate;
- the pixel definition layer, wherein the pixel definition layer is provided on the planarization layer, and the pixel definition layer is provided with a first protrusion in the frame area;
- a cover plate, wherein the cover plate is located on a side of the substrate where the pixel definition layer is provided, and is disposed opposite to the substrate;
- a first encapsulation part, wherein the first encapsulation part is filled between the pixel definition layer and the cover plate and extends from the display area to the frame area, and the first encapsulation part at least covers a portion of the first protrusion;
- and
- a second encapsulation part, wherein the second encapsulation part is filled between the pixel definition layer and the cover plate and is arranged around the first encapsulation part;
- wherein the planarization layer is provided with a second protrusion in the frame area, and a portion of the pixel definition layer in the frame area covers the second protrusion.
