Abstract

A display panel and a display device is provided in the present disclosure, which belongs to the field of display technologies. The display panel includes a base substrate and a plurality of pixel circuits disposed on the base substrate. At least two pixel circuits in a same column are coupled with a same first initial power line, such that only a small quantity of signal lines need to be disposed on the base substrate. Accordingly, an area which needs to be occupied by the signal lines and is of the base substrate becomes smaller, thereby facilitating high-resolution design of the display panel.

Dependent claims

A display panel, comprising:

a base substrate;
a plurality of light-emitting elements disposed on a side of the base substrate;
a plurality of first initial power lines and a plurality of first reset signal lines which are disposed on a side of the base substrate;
and
a plurality of pixel circuits disposed on a side of the base substrate and arranged in an array, each of the plurality of pixel circuits comprising a first reset circuit and a drive circuit;
wherein the first reset circuit is coupled with a first reset signal line, a first initial power line, and a driving node, and is configured to transmit a first initial power signal provided by the first initial power line to the driving node in response to a first reset signal provided by the first reset signal line;
the drive circuit is coupled with the driving node and a light-emitting element, and is configured to transmit a drive signal to the light-emitting element based on an electric potential of the driving node;
and
among a plurality of pixel circuits in a same column, first reset circuits comprised in at least two pixel circuits share a same first initial power line.
