Barco - OverView D series - Doc-3353-2 - user's manual - Revision 04 - April 2005 ________________________________________________________________________ 2-2
2.1 Design
OVERVIEW D is a modular rear projection system for the construction of large Display Walls. The technologies used
guarantee the best optical properties for high-quality presentation of information with very simple integration
into higher-level systems.
Although different in screen size and resolution, the various members of the OverView D family all have the
same functionalities, with one exception: projection modules with SXGA+ resolution have two digital inputs, thus
providing redundancy options, cf. Source selection
Technology
OVERVIEW D combines the latest modern projection technology with sophisticated electronics and solid mechanics.
This design results in high image quality and reliability.
•High, constant reading accuracy over the complete display panel
Optimally adjusted high-performance lens systems guarantee a distortion-free and sharp image.
•Bright displays
A UHP™ lamp provides a high luminous flux, which is passed on at great efficiency by the illumination sys-
tem. (UHP is a trademark of Philips Electronics N.V.). Depending on the requirements, the illumination unit
can be equipped with 100 W lamps or 120 W lamps.
•Dual lamp system
The projection engines has a dual lamp system and can be operated in three operation modes: hot standby,
cold standby, auto switch mode.
In hot standby both lamps are on. In case of a lamp failure, the light output of the other lamp is immedi-
ately switched to illuminate the optics, and there is no noticeable effect on the displayed information: no
loss of information, no impact on quality. Switching time is about half a second.
In cold standby mode the second lamp is only switched on in case a failure occurs with the active lamp.
Since the second lamp needs some minutes to reach a stable operating temperature, at the beginning the
display will have reduced brightness. The contents of information, however, is available nearly without any
interrupt.
Auto switch mode is a special version of the cold standby mode: the lamps are active in turns: after a de-
fined period, the light path is illuminated by the other lamp. Since the lamp is switched on some minutes in
advance, the takeover of the second lamp is nearly not noticeable. The cycle time can be set between
12 hours and 500 hours.
•High contrast
The screen has a surface which absorbs ambient light falling on it and increases the contrast.
•Electromagnetic immunity
Because of the digital projection technologies and their direct digital control OVERVIEW D guarantees highest
possible immunity against electromagnetic interference.
User riendly
The rear panel of an OVERVIEW projection cube gives free access to all control elements. The only maintenance
work, i. e. replacing the filter pad and the lamps, can be done within few seconds and makes no re-adjustment
necessary.
Because of the digital projection technologies and their direct digital control, the display is largely flicker-free and
therefore ergonomic.
Environmentally riendly
The burning life of the used lamps is very high. This long lamp lifetime and the low power consumption do not
only reduce the cost of ownership but also contribute to saving energy and natural resources.

Flexible con iguration
OVERVIEW D projection modules can be combined in rows and columns to realize Display Walls of virtually unlim-
ited size. The setup of the projection modules can be linear or curved.

2.2 Components of an O erView 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.
