LG unveils glasses-free 3D mobile phone screen
Making 3D glasses a thing of the past, LG’s 3D display uses an applied parallax barrier technology, which delivers a series of light-blocking slits attached to the front of the LCD panel. The slits, or barriers, ensure that the left and right eyes see different images, creating an illusion of depth and a thoroughly convincing 3D effect.
Working closely with LG Display, LG has also drastically reduced crosstalk. The new display has straighter, more upright barriers that are very precisely aligned to the LCD panel. This technological advance not only means smoother, brighter, crosstalk-free images, but also a wider viewing angle than on previous parallax displays.
