After 10 years of lab work, Sharp has developed a 3D LCD display that works without glasses. They expect to use the displays in games at first, and expand into PCs and TVs. Production begins in a few months and products using them should be shipping in early 2003.

Three-dimensional displays that need no special glasses have been around for some time, he said.

But the main challenge was making it possible to switch between the ordinary 2-D mode and 3-D with the push of a button, while providing the same image resolution in the 2-D mode as in a standard display without 3-D capability.
