Television viewers will be carried into a new dimension this year when they shed their old sets and go 3-D.

Momentum for 3-D TVs has been heating up, helped by trendy box-office hits like "Avatar" as well as displays by many major electronics makers of 3-D TV technology at last month's Consumer Electronics Show, the world's biggest electronics trade show.

Facing tough global competition, particularly with South Korean rivals, Japanese TV manufacturers are jockeying for the lead in advanced 3-D technology.
