An apparatus for displaying images from a video projector. The apparatus
includes a virtual projector screen assembly with an elongate screen
element, such as a rod, that is mounted at one end to a base. The base is
adapted for pivoting about its axis, arid a driver mechanism pivots the,
base at high frequencies. During operation, the screen element oscillates
between two edge positions with images projected from the projector being
displayed on a side of the screen element facing or proximate to the
projector. The two edge positions can be thought of as intersecting at
the base and define a sweep angle (e.g., the angular difference between
the two outer travel points of the screen element that is typically less
than about 90 degrees). The driver may include a motor with an
oscillating output shaft that pivots the base such as with a belt
attached to the base.
