HP has begun developing a glasses-free three-dimensional display that is visible from as wide as 180-degree viewing angle, according to The Verge.
Using “directional pixels,” the prototype LCD screen displays holographic images that do not distort even as the viewer moves from any point within the 180-degree field of view, the report said, citing an article from the MIT Technology Review.
The directional pixels consist of three sets of nano-patterned grooves that cast off red, green and blue light in diverse directions.
The reflected light then forms a 3D image after passing through another LCD display, according to HP Labs researchers.
Nathan Ingraham writes that although the display is in its early stage, the researchers from HP Labs demonstrated an “impressive technical achievement. “
This 3D display requires 200 different static images, which viewers can see one meter away within the 180-degree field of view, according to one of the researchers.
In addition, a video playback can display 30 frames per second and is visible from a 90-degree viewpoint.
