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 improve the problem of uneven display brightness caused by the voltage drop of the anode power supply voltage on the signal line. The organic light-emitting display panel includes: an anode power line, the anode power line includes a first extension section and a second extension section, the head end of the first extension section is electrically connected to the driving power supply, and the end of the first extension section is electrically connected to the second extension section. The first ends of the two extension sections; each sub-pixel includes a light-emitting device and two pixel drive circuits, and the anode connection ends of the two pixel drive circuits are electrically connected to the anode of the light-emitting device; the anode power line connection ends of the two pixel drive circuits are respectively Electrically connected to the first extension section and the second extension section.

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...
