Abstract

The invention provides a display panel and a display device. The display panel includes a display area, a hole digging area, and a buffer area between the display area and the hole digging area. One or more retaining walls are formed on a pixel defining layer in the buffer area, and the top surface of the retaining wall is provided with at least one groove or protrusion; a packaging layer is arranged on a light-emitting functional layer and the retaining wall, and the contact area between the top surface of the retaining wall and the packaging layer is greater than the projection area of the positive projection of the top surface of the retaining wall on the substrate. Through arranging the groove or the protrusion on the top surface of the retaining wall in the buffer area, the contact area between the top surface of the retaining wall and the packaging layer is increased, and the problem of film layer peeling between the retaining wall and the packaging layer is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] There is a new type of O-cut OLED display panel, which is characterized in that an O-shaped through hole is designed in its non-edge display area, and modules such as cameras, infrared sensors, and earpieces can be placed under the O-shaped through hole. Since the position of this O-shaped through hole can be set arbitrarily, it can realize the flexibility of the position of the under-screen camera, infrared sensor, earpiece and other modules in the panel display area. Currently, in order to ensure the flexibility of OLED panels, TFE (Thin Film Encapsulation) technology is usually used for encapsulation and protection. TFE usually includes inorganic, organic, and inorganic laminated structures. The inorganic layer is usually deposited by chemical vapor deposition (CVD), physical vapor deposition (PVD) o...
