METHOD FOR REDUCING SEAMS OF GRATING PATTERNS GENERATED IN A MULTI-SCREEN OR A MULTI-CUBE

摘要

PURPOSE: A method for reducing seams generated in a multi-screen or a multi-cube is provided to reduce seam parts of grating patterns generated in the entire picture by the seam parts in a monitor or a screen. CONSTITUTION: Optical panels having expansion projection parts with a number same to the number of monitors or screens are installed in a front part of a multi-screen or a multi-cube. The optical panels expand an image on the monitor or the screen to reduce seams. The expansion projection parts are Fresnel lenses. A focus of each expansion projection part on the optical panels is identical to the center of the monitor or the screen.
