  • Publication number: 20160094838
    Abstract: According to one embodiment, a display device includes a switching liquid crystal unit, a display, and a controller. The switching liquid crystal unit includes optical elements switching an aperture pattern including an aperture portion and a light-shielding portion. The display overlaps the switching liquid crystal unit and displays parallax images including right and left eye images. The controller acquires positional information relating to a position of a viewer, and controls a position of the aperture pattern. The controller switches the aperture pattern from a first aperture pattern to a second aperture pattern so that a right eye always views the right eye image and a left eye always views the left eye image, and starts the switching before the viewer moves to an optimal switching position where a luminance viewed from the first aperture pattern is substantially equal to a luminance viewed from the second aperture patterns.

  • Publication number: 20160021362
    Abstract: A display device includes: a display unit that displays, in a screen, images corresponding to viewpoints existing in a X direction; and a parallax forming unit that divides light existing between the display unit and the respective viewpoints with respect to the X direction so that different lights reach the respective viewpoints from the display unit due to light blocking or refraction, and guides the images corresponding to the respective viewpoints to the respective viewpoints. In a case where the width of each of the pixels in the X direction and/or the width of each of the pixels in a Y direction is equal to or smeller than a predetermined width, the parallax forming unit divides light beams existing between the display unit and the respective viewpoints so that light of more than one pixel is included in each minimum divisional unit region formed through the dividing.
