Abstract

The invention provides a display panel, which has a display area, a barrier wall area surrounding the display area, and an edge area surrounding the barrier wall area; the display panel includes a substrate; an orthographic projection on the substrate an inorganic layer located in the display area, the retaining wall area and the edge area; a light-emitting functional layer disposed on the inorganic layer; and an encapsulation layer disposed on the light-emitting functional layer and covering the light-emitting functional layer , and the orthographic projection of the encapsulation layer on the substrate is located in the display area and the retaining wall area; the inorganic layer located in the edge area is provided with at least one first slot, and the first opening A first filler is arranged in the groove to form a crack prevention structure, which can restrain the cracks generated at the boundary from expanding in the bending process, and help to achieve the effect of narrow frame.

Description

technical field [0001] The present invention relates to the field of display, in particular to a display panel. Background technique [0002] With the development of science and technology and the improvement of human's requirements for the quality of life, various display electronic devices have entered the field of vision of human beings, and users' requirements for electronic devices are constantly being refreshed. Taking liquid crystal display panels as an example, flexible OLED display panels are Its high color gamut and high applicability are widely used. [0003] At present, in order to ensure the bending reliability of foldable flexible OLED devices, crack prevention structures are usually prepared in the bending boundary area of ​​the OLED device to prevent the cracks generated during the bending process from extending inward, reducing the bending of the OLED device. reliability. In the prior art, the design of a crack prevention structure is introduced at the per...
