1. A display system comprising:
an array of pixel circuits arranged in rows and columns, a pixel circuit of the array of pixel circuits including:
a drive transistor including a first terminal coupleable to a data line of the display system;
a storage capacitor coupleable across a gate terminal and the first terminal of the drive transistor; and
a light emitting device coupleable to a second terminal of the drive transistor different from the first terminal; and
a controller for driving the pixel circuit in a plurality of operation states for the pixel circuit including a programming state for programming the storage capacitor of the pixel circuit with use of a data voltage provided over the data line, and a measurement state for measuring a current passing through the drive transistor, the light emitting device, and the data line.
