Sharp was also showing off a 65-inch TV at the show, which brought PC and TV companies together with chipmakers and glass suppliers.

One of those glass companies, Corning, demonstrated its history of building larger and larger glass panels for televisions.

Plasma used to rule the roost in large-screen televisions, but LCD technology is moving up, as shown by LG Philips’ 47-inch model.

3M has come up with a way of reducing the power consumption of flat-panel displays without affecting image quality by recycling the light absorbed by polarizers in LCD TVs.

Samsung also demonstrated its work enlarging LCD screens with several televisions measuring 40 inches or greater.

Sharp’s 47-inch LCD TV is capable of showing high-definition images with a resolution of 1,920 pixels by 1,080 pixels.
