When an image on the display device utilizes the pulse width modulation method for expressing grayscale moves and observer’s eye tracks the image, visual artifacts such as distortion, ghost, and color breakup appear. Gray-level-dependent temporal distribution of light emission in a field is transformed into spatial visual artifacts.
