Abstract

The invention discloses a display panel, a driving method thereof and a display device. A light-emitting element of the display panel is driven by a pixel circuit comprising a driving transistor, a first initialization module, a data writing module and a light-emitting control module, and in the reset stage of the driving period of the pixel circuit, the first initialization module responds to a first driving signal; a reference signal is used for carrying out preset reset processing on a first node of a pixel circuit, the reference signal comprises a periodic state signal, each period of the signal comprises a first state signal and a second state signal which are alternate, and the preset reset processing comprises carrying out alternate reset by using the first state signal and the second state signal. Therefore, the hysteresis effect of the driving transistor caused by the signal applied to the first node in the display process of the previous frame of picture is eliminated, the problem that the pixel circuit is influenced by the previous frame of picture in the process of driving the light-emitting element to emit light is avoided, and the problem of picture ghosting possibly occurring on the display panel is effectively solved.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to a display panel, a driving method thereof, and a display device. Background technique [0002] For OLED (Organic Light-Emitting Diode, organic electroluminescence) display panels, Micro-LED (Micro-Light Emitting Diode, micro-diode) display panels and QLED (Quantum Dot LightEmitting Diodes, quantum dot light-emitting diodes) display panels and other new displays As far as the panel is concerned, the driving of its light-emitting unit usually needs to rely on pixel circuits including a plurality of TFTs (Thin Film Transistor, thin film transistors). [0003] In the actual application process, it is found that in some cases, the problem of image sticking will appear, which will have a negative impact on the user's actual experience. Contents of the invention [0004] In order to solve the above technical problems, the present application provides a display pan...
