Paper Abstract

The technology of scanning-backlight can effectively reduce motion blur in LCD, but reintroduce large area flicker phenomenon. Perception experiments were performed to study the flicker visibility in a scanning-backlight LCD system. Different operational modes of the scanning-backlight were used to generate different light performance. Five color blocks: red, green, blue, white and yellow were chosen as experimental stimuli to check the influence of color on flicker visibility in the most strict situation. Two natural images, for each with a colorful version, a black-and-white version, together with a uniform white block (without any details) with the same average luminance of the natural image, were adopted to verify the influence of color and details in image content on flicker visibility in normal viewing situation. Results show that, color has no statistically significant influence on flicker visibility when luminance profiles are similar. And details in image content can effectively decrease sensitivity to flicker visibility, which could because details can distract viewer's attention away from flicker perception.
