Abstract

The invention discloses a display panel and a display device. A light-emitting element in the display panel is connected with an initialization node through a selective conduction element, the selective conduction element can enable the light-emitting element to be conducted with the initialization node in a display stage so as to be connected with a pixel circuit and perform light-emitting display under the control of the pixel circuit, and in a non-display stage, the selective conduction element can enable the light-emitting element to be connected with the initialization node. The selective conduction element can enable the light-emitting element to be disconnected with the initialization node, so that light-emitting in the non-display stage when the first electrode and the second electrode of the light-emitting element are reversely connected is avoided. Moreover, a first storage capacitor connected with the initialization node is further arranged in the display panel, when voltage reset is conducted on the initialization node through the first transistor, the first storage capacitor can store reset electric energy. In the non-display stage after reset, the reset electric energy stored in the first storage capacitor can counteract the leakage current flowing through the initialization node of the transistor in the pixel circuit, and the light-emitting element is prevented from emitting light due to the leakage current in the non-light-emitting stage.

Description

technical field [0001] The present application relates to the technical field of display devices, and more specifically, to a display panel and a display device. Background technique [0002] With the continuous advancement of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable tool for people today. . [0003] The main component of the display device to realize the display function is the display panel. The display panel has a plurality of sub-pixels for image display. For a display panel using a light-emitting element capable of actively emitting light as a sub-pixel, a pixel circuit is required to control the light-emitting element to perform light-emitting display. [0004] In the existing display panel, if the two electrodes of the light-emitting element are reversely connected, the light-emitting element will emit light d...
