THREE-DIMENSIONAL DISPLAY DEVICE, HEAD-UP DISPLAY SYSTEM, AND MOBILE BODY

WIPO Patent Application WO/2023/228887

A1

This three-dimensional display device comprises: a display panel having a display surface including sub-pixels; a parallax barrier having a light-transmitting area and a light-blocking area; a position acquisition unit that acquires the positions of the user's eyes; and a controller that synthesizes a mixed image displayed on the display surface. The controller successively allocates a first image or a second image having a parallax with respect to the first image to n sub-pixels arranged in accordance with the parallax barrier. The parallax barrier has an aperture ratio of 0.5+m/2n, where m is an integer greater than or equal to 0 and less than n. The controller causes sub-pixels observed across one end of the light-transmitting area and sub-pixels observed across the other end of the light-transmitting area to display a low-luminance image. The number of sub-pixels displaying the low-luminance image is the same on the one end side and the other end side of the light-transmitting area.
