摘要:
External compensation of display panels may employ measurement or sensing circuitry configured to measure the output of a pixel and compensate for variations. Due to effects from the sensing circuitry, a mismatch between a target current and the actual current in the pixel may occur. Systems and methods that compensate for the effects from sensing circuitry and reduce or mitigate the mismatch are described. Systems and methods described herein include compensation circuitry that is capable of employing correction factors to compensate for the effects due to the presence of sensing circuitry. Methods for determining the correction factor are also described.
