Japan's Sharp Corp. said Wednesday it had developed a liquid crystal display television that is less than an inch thick.

The technology used in the prototype allows the company to cut the thickness of a 52-inch flat television to just two centimetres (0.79 inches) for the main display section, less than one quarter that of its current thinnest model.

It has a power consumption half that of existing Sharp models and a much better contrast ratio.

The prototype "far surpasses existing models in terms of image quality, thin-profile design, and environmental performance," Sharp announced.

A commercial launch date has not yet been decided.

Sharp is a pioneer of LCD screens, having launched one of the world's first LCD pocket calculators in 1973.
