Japan-based consumer electronics maker Sharp Corp. announced that it has developed a LCD that shows totally different images to people viewing the screen from the left and the right.

According to Sharp, one person can be surfing the Internet, using the display as a PC screen, while another person watches a movie or TV broadcast. The unit also works for watching two TV channels.

Sharp said the two-way viewing-angle LCD will go into mass production in July 2005 and will cost roughly twice as much as a standard display.

Sharp will offer the product for worldwide sale, but will also supply other manufacturers with the displays for various products expected later this year, said spokeswoman Miyuki Nakayama.

Sharp says the technology offers many possibilities. It can be used in cars so drivers can look at a map while the passenger watches a movie. Or at a store, sales clerks and clients can view different data on the same display simultaneously. Another possible use is for billboards that display two kinds of advertisements depending on where viewers stand. The display can also work in the regular way and show a single image to all viewers.

According to an AP report, images can overlap if viewers stand directly in front of the screen and moving a few inches to the left or right may be necessary for a clear view.

The technology is based on Sharp's 3D LCD displays, which work by projecting slightly different images to the right and left eyes without the use of special glasses. A switching liquid crystal material is laid on top of a thin film transistor (TFT) LCD to control the unit's backlight and displayed image. Sharp has been selling 3D laptops for a few years, aiming them mainly at engineers, architects and other professionals. (AP)
