  • 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.

  • Publication number: 20230266606
    Abstract: A three-dimensional display system, a head up display system, and a mobile object including a head up display system include a display apparatus, barrier, detection apparatus, and controller. The display apparatus has subpixels arranged in a grid along orthogonal first and second directions and displays left- and right-eye images respectively in first subpixels and second subpixels separated by a display boundary from among the subpixels. The barrier has a light shielding region that shields the left-eye image and the right-eye image, and a light transmitting region that causes at least part of the left-eye image to reach a left eye of a user and at least part of the right-eye image to reach a right eye of the user. The detection apparatus detects the left and right eye positions. The controller moves the display boundary based on at least a change in the positions of the left and right eyes.
