ABSTRACT:
A vibrating screen for image projection is rotated or subjected to a circular motion or vibration to enhance resolution of the image projected and focused thereon. A circular screen plate or disc is slidably engaged within a rotatable disc eccentrically. The rotatable disc is rotated with the circular screen plate restrained about its position allowed to slightly move within the rotatable disc. Thus, the screen plate or disc is moved or vibrated circularly. The center of gravity of the composite system of the rotatable disc and the screen plate is at the center of rotation of the rotatable disc.
