MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202514029214 A) filed by Distance Technologies Oy, Helsinki, on March 27, for 'multiscopic display with collimated backlight and controllable light diffuser.'
Inventor(s) include Urho Konttori; and 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: "Information indicative of a relative location of a first eye (112a, 206a, 208a, 220a, 226a) and of a second eye (112b, 206b, 208b, 220b, 226b) of an individual one of user(s) is obtained. A light field image is generated or retrieved. The light field image is displayed via a liquid crystal display device (102) for presenting virtual object(s). All the aforementioned steps are repeated for a given time period. During the given time period, it is detected when the first eye and/or the second eye lies outside a current viewing zone of a display system (100, 202). When it happens, a given first region of a backlight unit (BLU) (104, 216, 300) is determined to emit a first set of collimated light rays for presenting the virtual object(s) to the first eye, and a given second region of the BLU is determined to emit a second set of collimated light rays for presenting the virtual object(s) to the second eye. A corresponding first portion and a corresponding second portion of controllable light diffuser(s) (106, 204, 306) are selectively activated to horizontally diffuse the first set and the second set, whilst directing towards the first eye and the second eye, respectively."
