Mobile phone touchscreen with 3D without glasses

Parallax barrier technology means that special glasses are not required

The electronics group Sharp today, Friday, presented a new LCD touchscreen for mobile devices that can be switched between 2D and 3D operation. The 3D mode works without special glasses because it is based on a so-called parallax barrier. Compared to conventional 3D LCD approaches, the development is not only characterized by the touch functionality, but also by a high level of brightness and a remarkable contrast ratio.

Well-known 3D principle now with touch

The principle behind the 3D effect of the new display is the parallax barrier. This is an arrangement of vertical slits that influence the light path to the eyes in such a way that a sense of depth exists. Competitors such as Sanyo have also used this principle in the past. However, Sharp has now managed to combine this principle with a touch functionality of the display.
"This mobile 3D LCD technology is overwhelming," says technology portal Akihabara News. This is also due to the fact that Sharp promises a contrast ratio of 1000: 1, which is said to be about ten times that of previous 3D LCDs. According to Sharp, the brightness is around twice as high at 500 candela per square meter. The company also states that the screen resolution of 480 by 854 pixels is significantly higher than before.

3D touch screen

beauty mistake

The problem with parallax barrier technology is that the screen has to be viewed from a relatively narrow area so that the 3D effect really comes into its own. Sharp was unable to solve this with the new 3D touch display either, reports Akihihabara. However, the image quality outside of the ideal range should still outperform the competition.
According to the company, the 3,4-inch display, which can optionally be offered without touch functionality, is ideal for digital cameras or cell phones. Of course, other portable devices such as consoles would also be conceivable. According to rumors, Sharps technology will be used in Nintendo's announced 3D game handheld.
