CES 2009: LG shows first ‘Trumotion 480Hz’ LCD TV High-definition LCD TV to ‘up screen refresh rate'
06 January 2009
LG has revealed an LCD TV panel that delivers a refresh rate of 480 images per second – far higher than the refresh rates of current HDTV sets.
The concept display, unveiled at the CES 2009 held in Las Vegas, could be available in LG HDTV sets by the second-half of 2009, according to the company.
The screen uses a ‘scanning backlight’, according to LG, that enables to backlight to be repeatedly turned on and off to reduce motion blur. It says that when combined with its 240Hz technology, the display can refresh 480 images per second.
The effect, says the company, is a lower motion picture response time of just 4ms – which LG claims will eliminate motion blurring for fast-moving scenes and create a crystal clear image at all times.
