Abstract

The embodiment of the invention provides a display panel and display equipment. The display panel comprises a substrate, a packaging layer and a barrier structure, the packaging layer comprises an inorganic packaging layer, the inorganic packaging layer is arranged on one side of the substrate, and the inorganic packaging layer is a continuous film layer; the barrier structure comprises a stress release structure, the stress release structure is arranged on the side, close to or away from the substrate, of the inorganic packaging layer, the elastic modulus of the stress release structure is smaller than that of the inorganic packaging layer, and the stress release structure is used for releasing the cutting stress of the inorganic packaging layer. The barrier structure is arranged in the peripheral area, and the elastic modulus of the stress release structure in the barrier structure is smaller than the elastic modulus of the inorganic packaging layer, so that when the inorganic packaging layer is cut, the cutting stress is released by the stress release structure, cracks of the inorganic packaging layer can be reduced or eliminated, and the yield of the packaging layer is improved. Therefore, the packaging effect of the display area can be ensured, and the packaging reliability and the cutting yield of the display panel can be improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display panel and a display device. Background technique [0002] Organic electroluminescent devices (OLED, Organic Light Emitting Diode) have received great attention and development due to their flexibility, fast response time, wide color gamut, and low energy consumption. At present, the packaging of OLEDs is mostly filled with glue (Dam & Filler). After packaging, the OLED devices need to be cut to remove excess parts. [0003] However, at present, the encapsulation layer of the special-shaped OLED is prone to cracks during cutting, which leads to the failure of the encapsulation and affects the display performance and service life of the OLED. SUMMARY OF THE INVENTION [0004] In view of the shortcomings of the prior art, the present application proposes a display panel and a display device to solve the technical problem t...
