Embodiment Construction

[0058] 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.

[0059] As mentioned in the background art, in order to achieve higher pixel density in existing display panels, pixel circuits with fewer transistors are usually used. However, in a pixel circuit with a small number of transistors, the problem of poor display uniformity is likely to occur. The inventors have found through research that the reason for the above problems is that in the existing display panel, in order to achieve a higher pixel density, the pixel circuit is usually a 2T1C pixel circuit. In the proces...

Abstract

The embodiment of the invention discloses a display panel, a driving method thereof and a display device. The display panel comprises a plurality of pixel circuits, a plurality of data lines, a plurality of detection lines and control circuits in one-to-one correspondence with the data lines and the detection lines. The pixel circuit comprises a driving transistor, a detection transistor and a data writing transistor, the data writing transistor is used for writing data voltage into a gate electrode of the driving transistor, and the detection transistor is electrically connected with a sourceelectrode of the driving transistor; the control circuit is used for controlling the detection lines to be communicated with the initialization terminals and controlling the data lines to be communicated with the corresponding data terminals in a display mode; the control circuit is also used for controlling the detection lines to be communicated with the corresponding detection terminals and controlling the data lines to be communicated with the initialization terminals in a detection mode; and at least part of the data terminals are multiplexed as detection terminals. According to the technical scheme, the pixel density is improved while the display uniformity is improved; and the number of the data terminals and the number of the detection terminals can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a driving method thereof, and a display device. Background technique [0002] With the development of display technology, the requirements for display quality are getting higher and higher. [0003] In existing display panels, in order to achieve higher pixel density, pixel circuits with fewer transistors are usually used. [0004] However, in a pixel circuit with a small number of transistors, the problem of poor display uniformity is likely to occur. Contents of the invention [0005] The present invention provides a display panel, its driving method and a display device, so as to improve display uniformity on the premise of ensuring higher pixel density. [0006] In a first aspect, an embodiment of the present invention provides a display panel, including: a plurality of pixel circuits, a plurality of data lines, a plurality of ...
