3D touch screen mobile phone display from Sharp-No need to wear special glasses

Japanese electronics group Sharp presented a  touch screen liquid crystal display (LCD) that allows to see 3 D images in portable devices like cellphones and gaming consoles without using special glasses.

This type of display for mobile devices, which reacts to the touch of a finger, can really see the stereoscopic images without dedicated glasses  provided they are placed face to a distance of 30 centimeters. It is possible to display 3D views either by the two possible orientations of a screen, ie in portrait or landscape.

“We had in the past (2002, 2004 and 2005) developed several devices equipped with 3D displays did not require glasses, but it must be admitted that this had been a failure,” said a director of the Sharp’s LCD business, Yoshisuke Hasegawa.

The semiconductor division of Sharp has designed this 3D display device using the technology of  “interlaced effect“.  The extra cost compared to traditional screen is not excessive because the screen is raised up a standard LCD panel on which is placed a filter.

As per Sharp, the mass production of these displays will be started by September and the commercial products by mid 2011.
