DLP projectors vs. LCDs

Texas Instruments Inc., the company that invented digital light processing, wants to prove that DLP projectors surpass LCDs in length of service.

The company sponsored a longevity study by the Rochester Institute of Technology in New York, pitting five LCD projectors against two DLPs. The RIT researchers ran them all continuously for 4,000 hours. According to TI, average use for a DLP is about 1,000 hours a year.

In all cases, the RIT researchers said, LCD projectors began to show problems after several thousand hours of use. Although two LCDs were still performing well after 3,456 hours, none survived the entire test without serious image flaws.

But the two DLP projectors had the same image quality at the end of the test as when it began.
