MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202514034611 A) filed by Distance Technologies Oy, Helsinki, on April 8, for 'multiscopic display using stacked liquid crystal layers.'
Inventor(s) include Mikko Strandborg.
The application for the patent was published on Nov. 7, under issue no. 45/2025.
According to the abstract released by the Intellectual Property India: "A first virtual image and a second virtual image are obtained, based on a relative location of a first eye (120a) and a second eye (120b) of user(s) with respect to an image plane (122) of a display device (104). The display device comprises a backlight (108), a first polarizer (110) and a second polarizer (112), a first liquid crystal (LC) layer (114) and a second LC layer (116) arranged between the first polarizer and the second polarizer and having a gap (118). Drive signals are generated, based on the first virtual image, the second virtual image, and the relative location of the first eye and the second eye. The first LC layer and the second LC layer is controlled using the drive signals, to adjust a polarization of light passing therethrough, for producing a synthetic light field presenting the first virtual image and the second virtual image to the first eye and the second eye, respectively."
