DLP® Technology vs. LCD

From the classroom to the boardroom and everywhere in between, DLP® projectors deliver a picture that lasts. DLP® proves itself again in a 3rd round of testing. Projectors equipped with DLP® technology continue to shine bright - something to keep in mind when selecting a projector.

Picture reliability defined

Picture reliability is how the images from your projector will look over time. If you see an unusual amount of yellow or greenish hues in a projected image, then that is what is called Color Decay. Projectors with DLP® technology are virtually immune to Color Decay. However, LCD projectors can't make that same claim when put to rigorous testing.

According to tests done by Intertek, an impartial global leader in product testing, images on LCD projectors may permanently degrade over time. Not only do these tests validate the results of two previous studies, it's also important to note all of the steps that were taken to ensure fairness and accuracy. For example, all 54 of the test samples were acquired on the open market, all test equipment was calibrated to the proper NTSC standards, and all the manufacturers' recommended maintenance was performed on the projectors.

Intertek's test was made up of three different runtime cycles, each one representing a different type of user.

  • The 24/7 user - leaving the projector on continuously.
  • The classroom user - leaving the projector on for 5.5 hours at a time.
  • The business user - turning the projector on for 1.5 hours at a time.

In all three test cycles, projectors with DLP® showed no significant change in luminance, uniformity, contrast ratio or color reproduction. Meanwhile, the LCD projectors lost half their contrast ratio and their color uniformity deteriorated substantially.

The value of digital DLP® technology is more than an incredible picture. It's the ability to maintain that picture for years to come.
