Abstract

The invention discloses an organic light-emitting display panel and a display device. The organic light-emitting display panel includes: a substrate, an organic light-emitting device, and a packaging layer; the organic light-emitting display panel includes: a display area and a non-display area located on the periphery of the display area, wherein, The organic light-emitting device includes a common cathode layer, the common cathode layer extends from the display area to the non-display area, and in the direction from the display area to the non-display area, the end of the common cathode layer is provided with a sealing column, and the sealing column covers the pixel definition layer On the flat area, and the encapsulation layer covers the sealing column. By setting the sealing column on the last flat area in contact with the common cathode layer, the edge of the cathode is limited by the sealing column, and the structure formed by the last flat area and the sealing column is used as the bank of the encapsulation layer, which is beneficial to further reduce the organic The frame width of the light-emitting display panel makes it easier for the organic light-emitting display panel to meet the requirements of ultra-narrow frames.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to an organic light emitting display panel and a display device. Background technique [0002] With the development of technologies such as big data, cloud computing, and mobile Internet, human beings have fully entered the era of intelligence, including smart mobile communication terminals, smart wearables, and smart homes. Smart devices have become an indispensable part of work and life. As an important window for human-computer interaction in the era of intelligence, display panels are also undergoing major changes. Among them, the organic light emitting diode (OLED) display panel has become the next-generation thin film transistor liquid crystal display due to its advantages of thinner thickness, lighter weight, active light emission, bright picture, low power consumption, good flexibility and wide color gamut. (Thin film transistor-Liquid crystal display, TFT...
