Abstract

The invention provides a display panel, a driving method thereof and a display device, relates to the technical field of display, and aims at improving the life matching degree of different colors ofsub pixels. The display panel comprises repetition units, each repetition unit comprises a first type of sub pixels, common sub pixels and a second type of sub pixels, the common sub pixels and the first type of sub pixels form a first pixel unit, and the common sub pixels and the second type of sub pixels form a second pixel unit; and a driving period includes a charging period and a light emission control period. The method comprises that in the charging period, data signals are written into the first type of sub pixels, the common sub pixels and the second type of sub pixels; in the light emission control period, the first type of sub pixels, the common sub pixels and the second type of sub pixels are driven to emit light under effects of the corresponding data signals; and the light emission time length of the common sub pixels is lower than that of any of the first and second types of sub pixels. The method is used to driving the display panel to display a frame.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a driving method of a display panel, a display panel and a display device. 【Background technique】 [0002] Compared with traditional liquid crystal display devices, organic light-emitting diode (Organic Light-Emitting Diode, hereinafter referred to as OLED) display devices have advantages such as wide color gamut and high contrast, and have been more and more widely used. [0003] The OLED display device includes a display panel, and the display panel includes sub-pixels of multiple colors, and each sub-pixel includes an organic light emitting diode for emitting light of a corresponding color. Generally, an organic light emitting diode includes an anode, a light emitting layer and a cathode. Since the materials of the light emitting layers of sub-pixels of different colors are different, the light-emitting lifetimes of the sub-pixels of different colors are also differ...
