CONTROL METHOD FOR PIXEL CIRCUIT, CONTROL CIRCUIT FOR PIXEL CIRCUIT AND DISPLAY DEVICE
First Claim
1. A control method for a pixel circuit, wherein the pixel circuit comprises a driving transistor configured to drive a light-emitting element, a timing sequence of the pixel circuit comprises a driving display stage and a non-display stage, and the non-display stage comprises a reverse bias time period;
- wherein the control method comprises;
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 reverse biased.

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.
