Problems solved by technology

However, the retaining wall in the above-mentioned prior art has a large width and is relatively close to the cutting edge. Therefore, when the flexible organic light-emitting display device is bent, cracks are likely to occur at the position of the retaining wall, and the cracks will quickly extend to the display area. , affecting the encapsulation effect and service life of organic light-emitting display panels

Abstract

The invention discloses an organic light-emitting display panel and an organic light-emitting display device. The organic light-emitting display panel comprises a substrate, an organic light-emitting structure and at least one barricade, wherein the barricades surround the organic light-emitting structure and point to the edge along the geometric center of the substrate, and the barricades are sequentially arranged. In the direction perpendicular to the stacking direction of the substrate and the organic light-emitting structure, the barricade closest to the edge of the substrate is the first barricade, and the first barricade is formed by connecting one or more nonlinear sub barricades, so that the stress area of the first barricade is increased, the effect of dispersing stress generated on the edge when the organic light-emitting display device is bent is achieved, and then the phenomenon that cracks generated by the stress effect stretches to a display region is avoided.

Description

technical field [0001] Embodiments of the present invention relate to organic light emitting display technologies, and in particular to an organic light emitting display panel and an organic light emitting display device. Background technique [0002] Organic light-emitting display devices have the advantages of high contrast, wide viewing angle, low power consumption, thinner volume, etc., and are currently one of the most concerned technologies in flat panel display technologies. Different from traditional flat-panel displays, organic light-emitting display devices can realize flexible displays if flexible materials are used as substrates, thereby creating fantastic visual effects. Flexible organic light-emitting display devices can be used in many fields by virtue of their bendability, such as rollable display devices. [0003] The non-display area of ​​the flexible organic light-emitting display device is usually provided with a barrier surrounding the display area, whi...
