Abstract
A control method for a pixel circuit, a control circuit for a pixel circuit and a display device are provided. A timing sequence of the pixel circuit includes a driving display stage and a non-display stage. The non-display stage includes a reverse bias time period. The control method includes: inputting, in the reverse bias time period, a first control signal to an input end of the pixel circuit to make both the light-emitting element and the driving transistor to be reverse biased.
