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 voltage drop variation of the anode power supply voltage during transmission, thereby improving the problem of uneven display brightness caused thereby. The organic light-emitting display panel includes: an anode power line located on the source-drain metal layer, the anode power line includes an anode signal line and an anode power connection line; an auxiliary connection line, the auxiliary connection line includes a first auxiliary connection line located in the first frame area , the second auxiliary connection line located in the second frame area, the third auxiliary connection line located in the third frame area, and the fourth auxiliary connection line located in the fourth frame area; the first auxiliary connection line, the second auxiliary connection line, the third auxiliary connection line and the fourth auxiliary connection line are located between the source-drain metal layer and the organic light-emitting layer; in the third frame area and the fourth frame area, the auxiliary connection line is electrically connected to the anode power line through the via hole.

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] With the development of display technology, Organic Light Emitting Display (OLED) panels are more and more widely used due to their excellent characteristics such as self-illumination, high brightness, wide viewing angle, and fast response. The organic light-emitting display panel includes a light-emitting device, a pixel drive circuit corresponding to each light-emitting device, and an anode signal line. The pixel drive circuit is used to drive the light-emitting device to emit light to realize the display of sub-pixels. extending to the other opposite end for transmitting the anode power supply voltage to each pixel driving circuit in the display area. [0003] However, with the continuous improvement of resolution, the available space in the display area is getting smaller and...
