Performance Improvement
Technologies
The 2005-2006 PTV product line uses several new
performance improvement technologies for LCD and
DLP displays.
LCD Improvements:
• Quick Motion™
• SmartShutter™
DLP Improvements:
• 1080p
• Dark Detailer™
• 10,800 RPM Color Wheel
Quick Motion™ is an advanced high speed drive sys-
tem that derives faster response from LCDs, virtually
eliminating the blurs that often occur when the moving
picture has fast motion.
SmartShutter™ is a dynamic aperture system that im-
proves black levels and adds a large palette of dark
grey shades. It does this by reducing light output during
dark scenes without negatively affecting other picture
characteristics.
Shown in Figure 1-4 , the SmartShutter High Contrast
Unit (HCU) is located in the light path between the lamp
output and the optics.
The HCU is a motor driven device that dims the lamp
output by physically blocking it with movable louvers.
See
Figure 1-5 . As dark scenes are detected, the lou-
vers move from position A, full light output, through
positions B, C and D to accurately control the amount
of light necessary as the picture brightness varies. It is
controlled by the PWB-Motor Driver.
