Problems solved by technology

[0003] However, the organic light-emitting display panel is provided with a pixel driving circuit for driving the light-emitting device to emit light. The pixel driving circuit includes a transistor, and the channel of the transistor is formed on a semiconductor layer. The bending stress characteristic of the semiconductor layer is poor. During the folding process, the stress is easy to concentrate on the semiconductor layer, which may cause the fracture of the semiconductor layer in the transistor, which will adversely affect the display

Abstract

Embodiments of the present invention provide an organic light-emitting display panel and a display device, which relate to the field of display technology, and can reduce the probability of fracture of a semiconductor layer of a transistor in an effective pixel drive circuit caused by bending, thereby improving the adverse effect on display caused thereby. The organic light-emitting display panel includes: a display area, the display area includes a bending display area and a non-bending display area; a pixel definition layer, a plurality of openings are arranged on the pixel definition layer, and the plurality of openings are evenly distributed in the display area; and each The light-emitting device corresponding to the opening, the light-emitting device includes an anode, an organic light-emitting layer and a cathode, the organic light-emitting layer is located in the corresponding opening; an effective pixel driving circuit corresponding to each light-emitting device, the effective pixel driving circuit is electrically connected to the corresponding light-emitting device The anode of the anode; the effective pixel driving circuit is located in the non-bending display area, and the effective pixel driving circuit is not provided in the bending display area.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light-emitting display panel and a display device. Background technique [0002] At present, display technology has penetrated into every aspect of people's daily life, and correspondingly, more and more materials and technologies are used in display screens. Currently, mainstream display screens mainly include liquid crystal display screens and organic light-emitting display panels. Among them, due to the self-luminous performance of the organic light-emitting display panel, compared with the liquid crystal display, the most energy-consuming backlight module is omitted, so it has the advantage of being more energy-saving; in addition, the organic light-emitting display panel is also flexible and bendable. . [0003] However, the organic light-emitting display panel is provided with a pixel driving circuit for driving the light-emitting device to emit light....
