Abstract
An organic light-emitting diode (OLED) display panel, a manufacturing method thereof, and an OLED display device are provided. In the OLED display panel, by disposing a stress buffering member in a concave corner of an undercut section, a stress at the concave corner is eliminated, and the undercut section is prevented from being broken, such that a technical problem that an existing OLED display panel is easily broken from a concave corner of a undercut section, which leads to a failure of the OLED display panel, is solved.
Claims20
An organic light-emitting diode (OLED) display panel, comprising:
- a special-shaped cutting area;
- and
- a display area surrounding the special-shaped cutting area, wherein the display area comprises an active display area, a first encapsulation area, and a second encapsulation area, and the first encapsulation area and the second encapsulation area are disposed between the active display area and the special-shaped cutting area;
- wherein a stress buffering member is disposed in a concave corner of an undercut section of the second encapsulation area.
A manufacturing method of an organic light-emitting diode (OLED) display panel, comprising:
- providing a substrate, and etching a second flexible layer and a second barrier layer to form an undercut section, wherein the substrate comprises a first flexible layer, a first barrier layer, the second flexible layer, and the second barrier layer;
- forming a thin film transistor array layer on the substrate;
- forming a luminous functional layer on the thin film transistor array layer;
- forming a first inorganic layer on the luminous functional layer;
- forming an organic layer on the first inorganic layer, and etching the organic layer in a second encapsulation area to form a stress buffering member in a concave corner of the undercut section, wherein the OLED display panel comprises a special-shaped cutting area and a display area surrounding the special-shaped cutting area, and the display area comprises an active display area, a first encapsulation area, and the second encapsulation area, and the first encapsulation area and the second encapsulation area are disposed between the active display area and the special-shaped cutting area;
- and
- forming a second inorganic layer on the first inorganic layer and the organic layer, wherein an encapsulation layer comprises the first inorganic layer, the organic layer, and the second inorganic layer.
An organic light-emitting diode (OLED) display device, comprising an OLED display panel, wherein the OLED display panel comprises:
