  • Publication number: 20240089422
    Abstract: A three-dimensional display device includes a display panel that emits image light, a barrier panel overlapping the display panel in an optical path of the image light and including multiple shutter cells (S) switchable between a transmissive portion and a light-blocking portion, a position detector that detects a position of at least one of a first eye or a second eye of a viewer, and a controller that controls the display panel and the barrier panel. The controller calculates a cumulative error between a barrier pitch (Bp) and an image pitch (k) corresponding to positions of the first and second eyes of the viewer based on position detection information from the position detector, and controls, when a ratio of the calculated cumulative error to one dot is greater than a first ratio, the image pitch (k) to be greater by at least one dot to reduce the cumulative error.
