The integration of Optical
Dimming allows
image equalizing capability
Optical Dimming allows brightness
adjustment of the lamp within 50-
100% range before the light reaches
the DLP chip. This feature allows to
control brightness of all the screens to
reach equal luminance values.
In particular, this design allows for the
following advantages compared to
conventional electronic dimming:
• dimming of the lowest black level
• brightness control without loss of
contrast
• brightness control without loss of
color depth
By applying patent pending Dynamic
Feedback technology to the Optical
Dimmer, every module can be set to
an arbitrary luminance value and be
calibrated to this “brightness setpoint”.
This way all modules can be set to a
common luminance value while
retaining the original contrast and color
depth, which makes the display wall
look like ‘one picture’. A feedback
central loop maintains a constant
brightness level over time and
therefore allows the display image to
remain equal in time and from module
to module. Finally, the dimmer can be used for
ergonomic reasons, where the whole
wall can be dimmed in certain
applications, for instance for day and
night modes.
On-screen menus
An extensive on-screen display gives
access to a clear and extensive menu
for displaying the status or for
accessing the control parameters of the
projection module such as numerous
patterns that are stored for image
optimization, lamp changes, dimming,
brightness & contrast control,…The
menu supports many languages
including Asian characters.
