2.2 Compo nents of an OVERVIEW CDG67-DL DISPLAY WALL
An OVERVIEW CDG67-DL Display Wall consists of two main components: the projection modules
housing the dual lamp projector and the graphical controller.
2.2.1 Projecti on Module
The projection module is the component for generating the displays of OVERVIEW CDG67-DL.
The light of a UHP™ lamp is directed via an optical system to a Digital Mirror Device whose im-
age 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.
