Applications and Configurations of a One-Chip DLp projection system

Rear projection cubes for 24-hour operation, televisions, home theatre systems, and business projectors using DLP technology rely on a single-chip configuration as described above (Figure 4.31).

White light passes through a colour wheel filter causing red, green, and blue light to be shone in sequence on the surface of the DLP chip. The switching of the mir­rors and the proportion of time they are ‘on’ or ‘off’ is coordinated according to the colour shining on them. The human visual system integrates the sequential colour and perceives a full-colour image. DLP cubes are available in various resolutions: SVGA, XGA, SXGA, SXGA+, and HDTV. Sizes range from 50 to 100 inches.

Extreme reliability, perfect image quality, and long-term stability have enabled DLP – based rear projection cubes to become state-of-the-art in control room applications.

4.5.10.2 advantages of DLp Technology

• High mean time between failures (MTBF) of the DMD chip, up to

100,0 hours.

• Long-term stability and reliability.

• Excellent picture quality (colour, brightness, and contrast).

• Low maintenance interventions, requires few readjustments.

• No burn-in or image retention of static pictures.

• Digital technology.

• The lamp has a long life.
