Stereoscopic display device
A configuration of a stereoscopic display device that is capable of maintaining crosstalk at a low level even when a viewer moves is provided. A stereoscopic display device (1) includes: a display panel (10) for displaying an image; a switch liquid crystal panel (20) that is arranged so as to be stacked on the display panel (10); a position sensor for acquiring position information of a viewer; and a control unit for moving a parallax barrier in which transmitting regions and non-transmitting regions are formed in periodic fashion in a predetermined alignment direction, in such a manner that the parallax barrier is moved in the predetermined alignment direction in accordance with the position information, and causing the switch liquid crystal panel (20) to display the parallax barrier. The switch liquid crystal panel (20) includes: a liquid crystal layer (23) in which refractive index anisotropy Δn of liquid crystal molecules is 0.14 or less; a first substrate (21) and a second substrate (22) that face each other with the liquid crystal layer (23) being interposed therebetween; and an electrode group including a plurality of electrodes that are formed on at least one of the first substrate (21) and the second substrate (22) and are arranged in the alignment direction.
MULTIVIEW DISPLAY AND METHOD HAVING SHIFTED COLOR SUB-PIXELS
A multiview display includes an array of light valves having rows of a repeating plurality of color sub-pixels and arranged as a plurality of multiview pixels configured to modulate directional light beams as color pixels of views of a multiview image. A first row of the repeating plurality of color sub-pixels is offset from a second row of the repeating plurality of color sub-pixels in a row direction by an integer multiple of a width of a color sub-pixel. The offset of the first and second rows is configured to provide corresponding color sub-pixels in adjacent multiview pixels having different colors to mitigate color fringing associated with the color pixel of the multiview image.

Image display device having diffusing means or image separating means allowing image to be observed
A parallax composite image displayed by image display means may be observed as predetermined parallax image at predetermined position by reflecting and guiding light from light source means and by using a diffusion pattern in which diffusion patterns are engraved at predetermined intervals to diffuse and transmit incident light on the diffusion pattern to the image display means. A fine notched structure is provided to cyclically and symmetrically vary the diffusion patterns in the horizontal direction. A structure is provided to control an amount and range of blur of pixels visible through light diffused toward the image display means by the diffusion pattern to which recesses and protrusions are added. By evaluating and adjusting a cycle of the notched structure so as to be appropriate, resultant adverse effects from the notched structure itself may be suppressed. Bright-dark patterns having a relatively long cycle may be reduced without increasing crosstalk.
Control of directional display
Disclosed is a light guiding valve apparatus including an imaging directional backlight, an illuminator array and an observer tracking system arranged to achieve control of an array of illuminators which may provide a directional display to an observer over a wide lateral and longitudinal viewing range, wherein the luminous intensity of optical windows presented to the observer as viewing windows is controlled dependent on the lateral and longitudinal position or speed of an observer. Further an optical window control system may comprise detection of an observer's hand. An image control system may comprise a method to provide an image that can be switched from a first mode with a first brightness into a second mode with a high brightness region and low brightness region, where the brightness of the second low brightness region is matched to the first brightness.
Display device
