Abstract
Methods for mitigation of sensing error effects in display panels are disclosed. Display panels, such as pixel-based panels, may have circuitry to sense the luminance values, compare measurements with target luminance values, and provide corrections. Sensing errors, such as ones caused by sensor hysteresis and thermal fluctuations, may lead to overcorrections and visible artifacts. Mitigations schemes discussed herein include filtering of sensed signal with low pass filters, partial correction strategies, and feedforward sensing schemes. Circuitry that implements these schemes are also discussed.
