MUMBAI, India, Nov. 7 -- Intellectual Property India has published a patent application (202514026630 A) filed by Distance Technologies Oy, Helsinki, on March 23, for 'local dimming and compensation in light field display.'
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: "An optical combiner (108, 402) is employed to reflect a first part and a second part of a synthetic light field (116) towards a first eye (122a, 202a, 316a, 322a, 410a) and a second eye (122b, 202b, 316b, 322b, 410b) of user(s) (124), respectively, whilst optically combining the first part and the second part with a real-world light field (114). Portion(s) (412a, 412b) of the optical combiner from which a part of the synthetic light field is reflecting towards a given eye (410a, 410b) of a given user is determined, based on a relative location of the given eye with respect to the optical combiner. Portion(s) of active optical device(s) (110) that corresponds to the portion(s) of the optical combiner are activated, to decrease transmittance of the real-world light field passing through the portion(s) of the optical combiner towards the given eye, and/or to increase reflectance of the synthetic light field being reflected by the portion(s) of the optical combiner towards the given eye."
