A system and method for setting one or more compensation coefficients for a transistor. In some embodiments, a method for setting a first compensation coefficient for a transistor includes: determining a plurality of measured transistor currents, each at a respective one of a plurality of transistor control voltages; setting the first compensation coefficient based on the measured transistor currents and the transistor control voltages; and adjusting a voltage applied to a gate of the transistor based on the first compensation coefficient, the voltage corresponding to a color value.
