Claim 19:
20. An integrated chip configured to provide at least one signal for a pixel circuit, wherein the pixel circuit comprises:
a drive module and a data write module;
wherein the drive module comprises a drive transistor;
wherein the data write module comprises a data write transistor and a bias transistor, the data write transistor is configured to transmit a data signal, and the bias transistor is configured to transmit a bias signal;
wherein an operation of the pixel circuit comprises a bias stage, during the bias stage, the data write transistor is off, the bias transistor is on and provides the bias signal;
wherein the bias stage comprises m sub-bias stages, wherein m≥3; and
wherein an interval between two adjacent sub-bias stages is a third interval stage;
wherein at least two third interval stages have different durations;
wherein the integrated chip is configured to provide the bias signal to the bias transistor; and/or
wherein the integrated chip is configured to provide the data signal to the data write transistor.
