Abstract:
1. An autostereoscopic display apparatus for displaying an image segmented into plural parallax images in a horizontal direction, the apparatus comprising: a two-dimensional display including color subpixels that are arranged in a horizontal direction and in a vertical direction, respectively; a plurality of cylindrical lenses provided on the two-dimensional display to observe the color subpixels therethrough, and arranged parallel to each other, a temperature sensor configured to measure an ambient temperature of the cylindrical lenses; and a parallax image changer configured to change the parallax images based on the ambient temperature measured by the temperature sensor, wherein when a pixel pitch of the color subpixels in the horizontal direction is defined as px, a pixel pitch of the color subpixels in the vertical direction is defined as py, a lens pitch of the cylindrical lenses in the horizontal direction is defined as Lx, an inclined angle of boundaries of the cylindrical lenses to the vertical direction is defined as θ, Ax and Ay are relatively prime natural numbers, Ax is equal to or larger than two, and Bx is a minimum natural number by which a value GF indicated in the formula (2) represents an integer value, px, py, Lx and θ satisfy relational expressions represented by the formula (1) to the formula (3).
