  • Patent number: 11562698
    Abstract: A display panel includes multiple pixel units that are arranged regularly. A pixel circuit is connected with a scanning signal line and a data signal line. The pixel circuit receives a data voltage transmitted by the data signal line and outputs a corresponding current to a light emitting device under a control of the scanning signal line. When a first light emitting unit is in a black state, the data signal line provides a reference black state voltage to a pixel circuit of the first light emitting unit. The driving method of the display panel includes: providing, by the data signal line, a first black state voltage to a pixel circuit of a second light emitting unit when the first light emitting unit emits light and the second light emitting unit is in the black state. The first black state voltage is less than the reference black state voltage.
