LG readies 480Hz LCD TVs for late 2009

Picture interpolation plus flashing backlight

Secure remote control for conventional and virtual desktops

LG is to released LCD TVs with a whopping 480Hz refresh rate, thanks to a clever flashing backlight.

The company's panel uses standard 240Hz interpolation technology, which seeks to eliminate the juddery look of old LCD TVs by creating extra picture fields and frames on the fly.

The upshot is smoother motion with no ghosting. Now LG's added a backlight that's rapidly turned on and off, which, the company claimed, delivers an effective 480Hz frame rate.

The technology "eliminates motion blurring for fast moving images and enabling a realistic, crystal clear picture".

The intensity of the backlight - when on - is adjusted according to the picture, reducing its overall energy consumption, LG said.

The 480Hz tellies are due in H2.
