REFLECTIVE SCREEN FOR A VARIABLE SHORT FOCAL PROJECTOR, CAPABLE OF REFLECTING IMAGES PROJECTED IN SHORT PROJECTION DISTANCE TO A POSITION OF A VIEWER

摘要

PURPOSE: A reflective screen for a variable short focal projector provides images in which a contrast remarkably is multiplied more than twice because external lights are diffused to outside and the images are expanded with a curved lens and viewers watch a dark color surface of a hidden side of the image reflective surface at the same time.;CONSTITUTION: A reflective screen(200) for a variable short focal projector(100) comprises a reflective structure(1) and reflective surface structure. The reflective surface structure comprises a screen structure. The reflective structure curves and reflects images of a short focal projector to a audience position(d). The short focal projector projects images at a projection angle of 30 to 80 degrees. The reflective structure is formed into a horizontal direction bar shape. A bar interval is 0.1 to 3mm unit. The reflective structure is vertically laminated. The reflective surface structure is composed of soft materials such as silicon, urethane, and plastic.;COPYRIGHT KIPO 2012
