Wall naming convention
OVf-SRR
 OV= overview
 S = screen size
–

–
–
5 = 50 inch
7 = 70 inch
8 = 80 inch
10 = 100 inch
 RR = resolution
– 08 = XGA = 1024x768 = 786 000 ~ 8
– 13 = SXGA = 1280x1024 = 1 310 720 ~13
– 15 = SXGA+ = 1400x1050 = 1 470 000 ~15
 f = front accessible
Examples :
 OV-508
 OV-715
 OV-1013

Screens
Rear projection screen requirements
 Viewable from all angles
 High contrast
 Focused
 Minimal reflection
Cleaning of screens :
 Avoid to touch screens !!!!
 See user manual for cleaning instructions.

Screens
 Screens can be mounted in different ways.
 Expand/shrink due to temperature and moisture
 Canned
– Minimal gap between screens
– Visible gap
– Only 50” and front access 70 “
 Canned – seamless
– No gap
– Screens push against each other
– Only 50”
 Stitched
– Small needle like wires hold the screens together
– No gaps
– Only from 70” onwards

Lamp cut-off voltage – lamp retry
When lamps get older they can
 Simply stop working and refuse to start again
 Explode…… : no danger !

Maintenance actions
- Defective lamp :
-
Retry lamp first (reset error + reselect lamp)
When fails again (same day)
Replace lamp
Lamp warm-up – wait 2 min.
Optimize the new lamp! (only possible in service mode).
 Air Filter Replacement
- Dependent on Contract and/or Need
- Don’t shake the dirty filter
- Dispose used filters – DO NOT CLEAN

Components : Typical delays & button functions
 Cooling / warming : 2 min
 Color stabilizing : 5 min
 Overtemp before shutdown : 5 min
On/Res button:
 Up
– 1-3 sec: switch on from standby
– 4-8 sec: toggle between IP address and error status
– > 10 sec: reset lamp error
 Down
– 1-3 sec: switch to standby
– 4-8 sec: not used (yet)
– >10 sec: self diagnostic of IU

One chip containing more than 1m mirrors
Each mirror representing one pixel
Pixel value is created through reflection time modulation

Technology : PU - Color sensor
Allows the BCM software (see further) to
 Have equal brightness on every projector
 Have equal color on every projector.

BCM: Brightness Lock
3 basic modes:
 Uncalibrated
– Brightness locking not active so dimmer wheel stays in last
known position.
– Color correction not active so native colors are shown.
 Brightness locked
– The brightness is dynamically controlled with the dimmer
wheel by using only the brightness information of the color
sensor. The colors are static.
 Sense 6 (License required, see BLM)
– Next to Brightness, color is also dynamically controlled. This is
done with the DMD chip.
