LED life extension tech
The Industrial Technology Research Institute (ITRI) in Taiwan has demonstrated a new invention, one which may potentially extend the useful life of LCD monitors and TVs. An increasing number of displays are using LED backlighting to provide greater brightness and contrast, but the ITRI notes that after 1,000 hours of use, current backlights almost invariably begin dimming. To counter this, the new system monitors the backlight, and makes adjustments as necessary with the goal of preserving color richness.
The Institute has not said by how long backlight life might be extended, but the technology is likely to be welcome in an industry still trying to push HDTV longevity over the 10-15 year mark. The ITRI has applied for five patents relating to its invention, and is said to be in talks with an unspecified panel maker for commercial products. [via DigiTimes]
