| 359448000 | With lens (e.g., camera obscura, etc.) | 8 |
| 20080252969 | Imaging Apparatus - Imaging apparatus including image creation means for creating a moving image, means for enlarging the image, and a screen on which the image is displayed in use to a viewer. The image creation means includes a substantially planar image creation screen on which the image is created. | 10-16-2008 |
| 20100091365 | Screen - A screen adapted to a projection device having a transparent layer, a plurality of light-mixing chambers, and a plurality of lens structures is provided. The light-mixing chambers are located on a back surface of the transparent layer away from the projection device. The lens structures are disposed on a front surface of the transparent layer facing towards the projection device and corresponding to the light-mixing chambers respectively. The size of the opening of the light-mixing chamber is smaller than the size of the bottom surface of the corresponding lens structures. The lens structure is adapted to refract a light beam from the projection device, and the opening of the corresponding light-mixing chamber is adapt to allow the light beam pass through, such that the corresponding light-mixing chamber is adapted to concentrate the light beam therein and transform the light beam into a light beam projected out of the screen. | 04-15-2010 |
| 20120229895 | SCREEN - A screen on which an image according to light incident thereon is displayed includes a plurality of lens trains on a light-exiting surface from which the light exits, and the plurality of lens trains are provided along a plurality of virtual reference lines extending in respective predetermined directions. Each of the lens trains is formed of a plurality of lens elements from which the light exits. At least some of the plurality of lens elements that form any of the lens trains are so disposed that the lens elements are shifted from the reference line along which the lens train extends. The screen can suppress degradation of a displayed image. | 09-13-2012 |
| 20130003174 | SCREEN - A screen allows an image according to light incident in an oblique direction from a predetermined light exiting position to be displayed. The screen includes a screen body having a reflection surface with a plurality of lens elements formed thereon, each of the lens elements reflecting the light incident thereon, a first layer (substrate) disposed on the side of the reflection surface on which the light is incident, and a second layer (air layer) interposed between the screen body and the first layer. The first layer has a refractive index greater than the refractive index of the second layer. The first layer has an angle changing portion formed in at least part of a region through which the light incident thereon passes, the angle changing portion so formed that the thickness thereof continuously increases with distance from the light exiting position. | 01-03-2013 |
| 20140049819 | HEAD-UP DISPLAY AND OPTICAL PROJECTION SYSTEM FOR A HEAD-UP DISPLAY - The present invention relates to an optical projection system for a display, and more particularly to an optical projection system for a head-up display with improved light efficiency. | 02-20-2014 |
| 20140133018 | Projector and Projection Screen - This projector includes a laser light generation portion, a projection portion scanning laser light, and a projection screen. The projection screen includes a lens member including a plurality of lens portions splitting the laser light and a diffusion member arranged to be opposed to the lens member, having an incident surface and a diffusion portion. The diffusion portion of the diffusion member is arranged at a position apart by a distance larger than the focal length of the lens member along an optical axis with respect to the optical principal surface of the lens member. | 05-15-2014 |
| 20150022886 | Micro-Projection-Display Devices and Adjustable Display Screens - An example micro-projection-display device includes: a projection lens, an elastic projection screen, a stretchable projection framework and a sliding block. At least one point of the stretchable projection framework is connected with the elastic projection screen, so that the stretchable projection framework is configured to control the elastic projection screen to stretch or retract. The sliding block is connected with the stretchable projection framework. The sliding block is configured to cause the stretchable projection framework to stretch or retract, so as to cause the elastic projection screen to stretch or retract. The projection lens is configured to project light onto the stretched elastic projection screen. | 01-22-2015 |
| 20150370157 | PROJECTION SCREEN AND PROJECTION SYSTEM USING THE SAME - A projection screen includes a reflector and a plurality of compound lenses. The compound lenses are arranged at the same side of the reflector in an array manner. Each of the compound lenses has a first lens portion and a second lens portion. The first lens portion is disposed between the second lens portion and the reflector. A surface of the first lens portion opposite to the reflector has a first radius of curvature, and a surface of the second lens portion opposite to the reflector has a second radius of curvature. The first radius of curvature has a length greater than the second radius of curvature. | 12-24-2015 |
