Embodiment Construction

[0044] 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 herein 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, the drawings only show some but not all structures related to the present invention.

[0045] As mentioned in the background art, the existing display panels are prone to problems such as flickering and motion blur during display. After careful research, the inventor found that the reason for this technical problem is: the display panel usually contains a plurality of pixel circuits, and the pixels The circuit includes a driving transistor and a light-emitting element. Due to the different grayscale values ​​to be displayed in adjacent pixel circuits, the voltages of the gates of the two driving transistors are diffe...

Abstract

The invention discloses a pixel circuit, a driving method thereof and a display panel. The pixel circuit comprises a data writing module, a driving transistor and a state resetting module, the driving transistor comprises a first grid electrode and a second grid electrode, and the data writing module is used for providing data voltage for the first grid electrode of the driving transistor in a data writing stage; the state reset module is used for writing a first conduction voltage into a second grid electrode of the driving transistor in a first state reset stage so as to enable the driving transistor to be conducted in a linear working area; the state resetting module is also used for writing a second conduction voltage into a second grid electrode of the driving transistor in a second state resetting stage so as to enable the driving transistor to be conducted in the saturated working area; the driving transistor is used for generating driving current according to data voltage in a light-emitting stage; wherein the first state reset stage and the second state reset stage are located between the light emitting stage and the data writing stage. The problems of flicker and motion blur can be solved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a pixel circuit, a driving method thereof, and a display panel. Background technique [0002] With the development of display technology, the application of display panels is becoming more and more extensive, and the corresponding requirements for display panels are also higher and higher. [0003] However, when displaying images, especially low-frequency displays, the existing display panels have problems such as flickering and motion blur, which seriously affect the display effect. SUMMARY OF THE INVENTION [0004] The present invention provides a pixel circuit, a driving method thereof, and a display panel to improve the phenomenon of flicker and motion blur at low frequency. [0005] In a first aspect, an embodiment of the present invention provides a pixel circuit, where the pixel circuit includes: [0006] Data write module, drive transistor and state r...
