2.2 Components of an OverView D display wall
An OVERVIEW D display wall consists of two main components: the projection modules housing the dual lamp pro-
jector and the graphical controller.
2.2.1 Projection module
The projection module is the component for generating the displays of OVERVIEW D The light of a UHP™ lamp is
directed via an optical system to a Digital Mirror Device whose image is projected via a high-performance lens
system onto the rear side of a screen.
Due to the dual lamp system, the availability of the Display Wall is about 100%: in case the lamp fails, the light
output of the second lamp is automatically switched into the light path.
Since the screen is illuminated right up to its edges, it is possible to construct Display Walls of any size by the
adjacent arrangement of several units.
