20100195190LENS ARRAY DEVICE AND IMAGE DISPLAY DEVICE - A lens array device and an image display device using the lens array device, which allow a lens effect characteristic different from that of a single variable lens array to be easily obtained, are provided. The lens array device includes a variable lens array and a fixed lens array. The variable lens array includes a plurality of variable lenses each having electrically-adjustable refracting power. The fixed lens array includes a plurality of fixed lenses each provided in correspondence to each of the plurality of variable lenses. Each of the fixed lenses has a refracting power which, once a corresponding variable lens has come to have a first refracting power, allows the first refracting power to be cancelled out.08-05-2010
20100238277STEREOSCOPIC DISPLAY DEVICE - A stereoscopic display device includes: a display panel having a display screen on which two-dimensional image is displayed, and configured to polarize image light of the image-displaying into a particular polarization direction; and a lens array element disposed to oppose the display screen of the display panel, and having a liquid crystal layer which includes liquid crystal molecules having a refractive index anisotropy and aligned in a predetermined orientation direction under no application of voltage. The lens array element is configured to electrically change the alignment of the liquid crystal molecules to generate a lens effect, and configured to selectively change a state of passing therethrough of the image light exiting from the display panel. The predetermined orientation direction of the liquid crystal molecules of the lens array element and the polarization direction of the image light are parallel to each other.09-23-2010
20100259697STEREOSCOPIC DISPLAY - A stereoscopic display includes: a display panel configured to display an image in either one of two or more arrangement states including a first arrangement state and a second arrangement state which are switchable with each other; and a lens array device arranged to face a display surface of the display panel. The lens array device produces a lens effect in a direction, the direction of effect being changed between in the first arrangement state and in the second arrangement state. The display panel includes an array of a plurality of sub-pixels, and a combination of sub-pixels used as a unit pixel is changed between in the first arrangement state and in the second arrangement state.10-14-2010
20110181827Lens array element and image display device - A stereoscopic display device includes a display panel performing image display, and a lens array element including a first electrode, a second electrode opposed to the first electrode, and a liquid crystal layer disposed between the first electrode and the second electrode, the lens array element being configured in such a manner that a lens effect on display image light from the display panel is controlled depending on a voltage applied to the first electrode and a voltage applied to the second electrode. One of the first electrode and the second electrode is structured to allow an electric field to be applied to the liquid crystal layer for each of a plurality of predetermined sub-regions, individually.07-28-2011
20110310320LENS ARRAY ELEMENT AND IMAGE DISPLAY DEVICE - Disclosed herein is a lens array element, including: first and second substrates; a first electrode group; a first switch group; a second electrode group; a second switch group; and a liquid crystal layer, wherein the lens effect of an arbitrary area of the liquid crystal layer changes with change in the statuses of the first and second switch groups.12-22-2011
20120008057Lens array unit and image display device - A lens array unit includes: first and second substrates disposed to be opposite to each other with a distance interposed therebetween; first and second electrode groups respectively formed on the surfaces of the first and second substrates facing the second and first substrates and having a configuration in which electrodes extending in first and second directions are arranged in parallel in the width direction at intervals; first and second switch groups respectively connecting first and second voltage generators applying a voltage to the first and second electrode groups to the electrodes of the first and second electrode groups; and a liquid crystal layer disposed between the first substrate and the second substrate, containing liquid crystal molecules having refractive anisotropy, and causing a lens effect by changing the alignment direction of the liquid crystal molecules depending on the voltages applied to the first and second electrode groups.01-12-2012
20120105753LIQUID CRYSTAL LENS ARRAY DEVICE, DRIVING METHOD THEREOF AND IMAGE DISPLAY DEVICE - A liquid crystal lens array device includes: a first electrode; a plurality of second electrodes arranged to face the first electrode, to which drive voltages having waveforms with phase differences therebetween are applied; and a liquid crystal layer arranged between the first electrode and the plural second electrodes, generating lens effects in accordance with potential differences between the drive voltage applied to the first electrode and drive voltages applied to the plural second electrodes.05-03-2012
20120113159STEREOSCOPIC DISPLAY APPARATUS AND DISPLAY METHOD FOR STEREOSCOPIC DISPLAY APPARATUS - A display apparatus includes: a display section that is driven to perform line sequential scanning and display a plurality of different viewpoint video images; a backlight that includes a plurality of sub-light emitting areas separated in the line sequential scanning direction; a light barrier that has a plurality of open/close unit groups each of which is formed of a plurality of open/close units, the open/close units in different groups opened or closed at different timings; and a backlight controller that controls light emission from the sub-light emitting areas in the backlight in synchronization with the line sequential scanning in the display section, wherein the backlight controller separately controls intensities of the light emitted from the sub-light emitting areas.05-10-2012
20120113319DISPLAY DEVICE AND DISPLAY METHOD - A display device includes: a display unit including plural display sections divided in a first direction and performing line sequential scanning in the first direction; and an interpolation picture generation unit generating an interpolation picture in accordance with a timing at which each display section is scanned based on supplied frame pictures, wherein the display unit displays the interpolation picture corresponding to the display section in each display section.05-10-2012
