Abstract:
1. A display system, comprising: a pixel circuit for operating a light emitting device to emit light according to programming information, the pixel circuit including: a drive transistor connected in series to the light emitting device, the drive transistor including a gate terminal, a first terminal and a second terminal, a first switch transistor including a gate terminal, a first terminal and a second terminal, the gate terminal of the first switch transistor being connected to a select line for operating the first switch transistor, the first terminal of the first switch transistor being connected to a data line providing a programming voltage according to the programming information during a programming cycle, the second terminal of the first switch transistor being connected to the gate terminal of the drive transistor, and a circuit for adjusting the gate voltage of the drive transistor by at least partially discharging the voltage on the gate terminal of the drive transistor through a discharge component having a resistance that varies as the pixel circuit ages, and a controller for operating the data line and the select line to drive the pixel circuit such that:
