LCD backlight technology continues to evolve with some technologies touted with a life of 100,000 hours. What is the AccuVIEW OCD’s backlight technology expected life?
LCD backlight technology is rated in mean time to half life or MTTH. Mean time to half life is the operational hours before the backlight diminishes to 50% of the original backlight intensity or readability. Texas Digital’s LCD backlight technology is rated at 50,000 MTTH. Assuming 20 hours of operation per day, this means the backlight intensity reaches 50% of the original brightness after almost 7 years of operation. While it may be true that the new technology has an “end life” of 100,000 hours, that is not an apples-to-apples comparison to MTTH and is, for the most part, a useless specification since MTTH is the standard measure of a unit’s useful life. Further, 99+% of the outdoor LCDs deployed today across all applications uses the same backlight technology deployed in the AccuVIEW and proven to be reliable over years of continuous life. Additionally, Texas Digital’s backlight technology is 50% more energy efficient than the “new” backlight technology and can save the restaurant
