Problems solved by technology

At present, packaging methods include thin film packaging and edge coating. Among them, the structure of thin film packaging is a multilayer stacked structure of organic layers and inorganic layers. In the multilayer stacked structure of organic layers and inorganic layers, the inorganic layer It can realize the function of blocking water and oxygen, and the organic layer can realize the function of planarization; the method of edge coating, such as adding a flake desiccant in the non-display area or coating a circle of desiccant on the edge of the display, this method is not conducive to narrow frame design

Abstract

The invention relates to a display panel and a display device. The display panel comprises a substrate base plate, an organic electroluminescent diode (OLED) pixel structure arranged on the substratebase plate and a packaging film arranged on the OLED pixel structure, wherein the OLED pixel structure is arranged in an array mode and comprises multiple sub pixels arranged in an array mode, the OLED pixel structure has the first direction and the second direction orthogonal to the first direction, an edge of the opening area corresponding to the sub pixels comprises a first portion of a line that is gradually away from the first direction, and the extending direction of the first portion and the second direction are not superposed. The display panel is advantaged in that the edge of the open area corresponding to the sub pixels can be set to comprise the first portion of the line that is gradually away from the first direction, the extending direction of the first portion and the seconddirection are not superposed, in the process of manufacturing an organic film packaging layer, the spreading effect of the organic film can be improved, packaging reliability is improved, and the display quality of the display panel is improved.

Description

technical field [0001] Embodiments of the invention relate to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) has self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response, can be used for flexible panels, and has a wide temperature range. Excellent characteristics such as simple structure and manufacturing process have been widely used in the field of display technology. [0003] The lifespan of OLED devices restricts the pace of its industrialization. In the process of manufacturing OLED devices, it is necessary to make pixel definition areas on the substrate, and then evaporate organic light-emitting materials into the pixel definition areas by vacuum evaporation. , Organic light-emitting materials are extremely sensitive to water and oxygen. Therefore, after the evaporation is completed, thin-film packaging or packaging by edge coating is required, otherwise the life...
