1. A method of measuring a signal offset of signals on a signal line of a display system having a pixel circuit, the method comprising:

  • generating a first signal from a first location on the signal line;

    measuring the first signal at a second location on the signal line upon expiry a first time duration sufficient to avoid settling effects, generating a first signal measurement;

    generating a second signal from the first location;

    measuring the second signal at the second location upon expiry of a second time duration insufficient to avoid settling effects, generating a second signal measurement; and

    comparing the first signal measurement with the second signal measurement to extract the signal offset.
