DLP-based projectors: A 2002 study by
the Munsell Color Science Laboratory
(MCSL) at Rochester Institute of Technology
compared the picture reliability of DLP-based
projectors to that of TFT-based projectors.
The initial test results, recently announced
by Texas Instruments, who commissioned
the study, assert that DLP-based projectors
demonstrated superior picture reliability
over the test period (4,000 hours) while
the LCD-based projectors suffered optical
degradation that was catastrophic. See ‘DMD
Field Reliability: A Comparison of Competing
Technologies used in Data Projectors,’ by
Michael R. Douglass and Rick W. McCall.

Lamp life: is used here as a measure of
brightness degradation only – it does not
indicate the time it takes a lamp to fail. It is
defined as the average time it takes for more
than 50 percent of a sample lamp population
to decrease in brightness by approximately 50
percent of the rated lumens.
