20100007818 | ILLUMINATION APPARATUS, ILLUMINATING METHOD AND DISPLAY APPARATUS - A light source is arranged at a side face of a light guide plate, and a beam direction regulator and a reflection plate are sequentially arranged at a side of the light guide plate opposite to an illumination direction. Furthermore, a transmittance/scattering switching device is arranged at an illumination direction side of the light guide plate. Light from the light source entering the light guide plate emerges in a direction opposite to the illumination direction, passes through the beam direction regulator, and is reflected by the reflection plate. The reflected light once again passes through the beam direction regulator, passes through the light guide plate, enters the transmittance/scattering switching device, and then emerges as light in a transmitting state or a scattering state. Thus, the occurrence of moiré effects and uneven luminance are suppressed, and an illumination apparatus capable of controlling an emerging light angular distribution is obtained. | 01-14-2010 |
20100060723 | DISPLAY SYSTEM - [Problems] To eliminate flicker when a normal image is presented to user employing an optical shutter from two types or more of image under intermittent illumination of such as fluorescent lamp. | 03-11-2010 |
20100177112 | IMAGE PROCESSING DEVICE, ITS METHOD AND PROGRAM, AND DISPLAY DEVICE - An image processing apparatus sequentially provides a display device with a plurality of image output including a first image, a second image set to become at least a part of an image that is not correlated with the first image when luminance values of pixels of the first image are added to it, and a third image set to become an image, which is obtained by adding luminance values of pixels of all pluralities of images, higher spatial-frequency components than those of the first image. The image processing apparatus has an optical shutter control unit for controlling an optical shutter provided between the display device and a viewer to make the shutter be in a light transmission state while a part of or all the first image is displayed, and in a light interception state while other images are displayed. | 07-15-2010 |

20150016085 | OPTICAL DEVICE, OPTICAL ELEMENT, AND IMAGE DISPLAY DEVICE - Disclosed are an optical device, an optical element, and an image display device that can achieve an improved absorption efficiency of excitation light. The optical device includes: a light-emitting element; a carrier generation layer on which light from the light-emitting element is incident and in which carriers are generated; a plasmon excitation layer that excites a plasmon, stacked on the upper side of the carrier generation layer and has a plasma frequency higher than a frequency of light generated when the carrier generation layer is excited by the light from the light-emitting element; and an exit layer that converts light or a surface plasmon generated on a surface of the plasmon excitation layer into light having a predetermined exit angle and from which the light having the predetermined exit angle exits. The optical device further includes a polarization conversion layer on the lower side of the carrier generation layer. | 01-15-2015 |
