1. An image display system comprising:
at least one display panel;
a memory circuit to store predefined image information, associated with all positions within a predefined space in which the
at least one display panel is provided, at least temporarily; and
a position sensing subsystem for detecting the position of the at least one display panel within the space,
wherein the at least one display panel presents at least a portion of the image information thereon according to its position
that has been detected by the position sensing subsystem in the space, wherein the at least one display panel presents the
portion of the image information in actual dimensions, and wherein
the at least one display panel includes a main display panel and a sub-display panel, each of the main display panel and the
sub-display panel being moveable within the space,
the position sensing subsystem includes a position sensing detector which detects at least the position of the main display
panel within the space, and
the display system includes a relative position sensing subsystem for detecting the relative positions and relative configurations
of the main and sub-display panels, the position and configuration of the sub-display panel within the space being detected
based on the relative positions of the main and sub-display panels.
