Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0032] As mentioned in the background art, there is a problem that increasing the refresh rate of the display panel will affect the display uniformity of the display panel. Usually, the driving technology of the display panel adopts the method of progressive scanning. In order to solve the problem of uneven display caused by the difference in the manufacturing process of the driving thin film transistor in each pixel driving circuit, it is necessary to set a compensation circuit in the pixel circuit to control the ...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes at least one first trunk initialization line, at least one second trunk initialization line and a plurality of branch initialization lines; each branch initialization line is connected to the first trunk initialization line through a first switch, and connected to the first trunk initialization line through a second switch Connected to the second trunk initialization line; the voltages on the first trunk initialization line and the second trunk initialization line are different; multi-row pixel circuits, the pixel circuit includes a first initialization signal terminal and a second initialization signal terminal; the first initialization signal terminal is connected to A branch initialization line, the second initialization signal terminal is connected to a branch initialization line. Through the technical solution of the embodiment of the present invention, while ensuring the display uniformity of the display panel, the wiring in the display area of ​​the display panel is saved, which is beneficial to the high PPI design of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] An organic light-emitting display device usually includes several sub-pixels, and each sub-pixel includes a pixel circuit and an organic light-emitting structure. The pixel circuit supplies a driving current to the organic light-emitting structure, and the organic light-emitting structure emits light in response to the driving current provided by the pixel circuit. Accordingly, an organic light-emitting display The device realizes full-color display. [0003] As the requirement for smooth experience of the display device is getting higher and higher, the requirement for the refresh rate of the display device is also higher and higher. However, the increase of the refresh rate is likely to affect the display uniformity of the display device. Contents of the invention [0004] The pre...
