Abstract

The invention discloses a driving method of a display panel, the display panel and a display device. The driving method of the display panel comprises the following steps: in a first light emitting phase, light emitting control circuits in at least one light emitting control circuit group output first light emitting control signals to an electrically connected pixel driving circuit, so as to control the pixel driving circuit to output a driving signal to an electrically connected organic light emitting element; and in a second light emitting phase, the light emitting control circuits in the atleast one light emitting control circuit group output the first light emitting control signals to the electrically connected pixel driving circuit, and the light emitting control circuits in the at least one light emitting control circuit group output second light emitting control signals to the electrically connected pixel driving circuit, so as to control the pixel driving circuit not to outputthe driving signal to the electrically connected organic light emitting element. By adoption of the driving method of the display panel disclosed by the invention, the organic light emitting elementis in a short-term DC bias light emitting state, thereby slowing down the polarization acceleration of an organic material, prolonging the service life of the organic light emitting element, and finally prolonging the service life 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 method for driving a display panel, a display panel, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel has the advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. Currently, it is widely used in display fields such as mobile phones, PDAs, and digital cameras. . [0003] However, with the use of the OLED display panel, the luminous efficiency of the OLED device decreases, and therefore, the OLED display panel has a problem of low service life. Contents of the invention [0004] The invention provides a driving method of a display panel, a display panel and a display device, so as to prolong the service life of the display panel. [0005] In the first aspect, an embodiment of the present invention p...
