20120127398 | BACKLIGHT SYSTEM AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME - A backlight system includes: a light-emitting section ( | 05-24-2012 |
20120268814 | REFELCTIVE FRONT SCREEN - A screen which reflects light emitted from a projector includes a light diffusion layer through which light incident from a specific angular region is diffused and transmitted and through which light incident from the other angular region is transmitted straight; area pairs having a mirror forming area and a non-mirror forming area; a light transmissive layer having a back surface, on which the area pairs are disposed, and an opposite surface being bonded to a back side of the light diffusion layer; and a specular reflection film formed on a back surface of each mirror forming area. An inclination of the mirror forming area with respect to a normal line of the screen close to the projector becomes larger than the inclination of the mirror forming area far from the projector within a cross section perpendicular to the mirror forming areas inside the screen. | 10-25-2012 |
20130170028 | SCREEN AND PROJECTION SYSTEM - A screen in which observation distance may be adjusted while maintaining image brightness and a projection system using the screen. In a light control layer of a screen, a first angle region that determines a diffusion distribution of a reflected light is different according to the screen position in a control direction in which light diffusion control is performed. Accordingly, a diffusion distribution of image light emitted from a screen surface is adjusted to be tilted downward by an upper end and upward by a lower end according to the screen position. Thus, for example, a size of a diffused angle range is maintained to be 30°, and a direction in which the image light is diffusion-emitted corresponds to an assumed position of an observer. The projection image can be observed while maintaining brightness of an image and the observation distance can be adjusted to be short. | 07-04-2013 |
