Abstract
Techniques for operating an electro-optic display to reduce the appearance of light edge artifacts in displayed images are described. A method for operating the electro-optic display includes detecting a null state transition of a first pixel when transitioning from a first image to a second image. The method further includes determining whether a threshold number of cardinal neighbors of the first pixel transition from a black state to a white state when transitioning from the first image to the second image. In response to a subsequent transition to a third image, the method further includes applying a voltage signal to the first pixel, wherein the voltage signal has a waveform configured to generate an optical black state for the first pixel.
