Patent number: 11914251Abstract: The invention relates to a light modulation device for a display for representing two- and/or three-dimensional image content or image sequences. The light modulation device comprises a light modulator and a controller. The phase and/or the amplitude of a light wave field, which is substantially collimated, can be varied by means of the light modulator depending on the location of the light modulator. The light modulator can be actuated by means of the control device. According to the invention, in the direction of propagation of the light wave field, at least one diffracting unit is arranged downstream of the light modulator. The diffracting unit has a variable diffracting structure. By means of the diffracting structure, the light wave field varied by the light modulator can be diffracted in a variable and predeterminable manner. Further, the present invention relates to a display and a method for producing a light modulation device.Type: GrantFiled: April 1, 2022Date of Patent: February 27, 2024Assignee: SEEREAL TECHNOLOGIES S.A.Inventors: Bo Kroll, Norbert Leister, Gerald Futterer, Robert Missbach, Stephan Reichelt

Patent number: 9860943Abstract: The present invention relates to a backplane device for a light source matrix. A light source is preferably a LED or an OLED. A pixel circuitry of the backplane device is assigned to a light source of the light source matrix for controlling the light source. One light source and one pixel circuitry constitute a pixel. The pixels of the light source matrix are classified according to a pixel characteristic. The order of switching the light sources on and/or off depends on the pixel characteristic and not necessarily on the location of the pixel on the backplane device. A current being applied to the light sources is controlled by at least one driver. The at least one driver is electrically connectable to at least one pixel. The at least one driver is not belonging to the pixel circuitry of the pixel.Type: GrantFiled: September 1, 2011Date of Patent: January 2, 2018Assignee: SEEREAL TECHNOLOGIES S.A.Inventor: Robert Missbach

Patent number: 9076375Abstract: A backplane device for a spatial light modulator for generating a two-dimensional and/or three-dimensional representation of a scene or of content. The spatial light modulator includes pixels having pixel addresses and being electronically controllable by the backplane device for assigning pixel values to the pixels. The backplane device comprises at least one electrode for each pixel, at least one analog line and at least one pixel addressing means. Such a pixel addressing means comprises x-addressing lines and y-addressing lines. Every pixel is connected to an analog line, to an x-addressing line and to a y-addressing line. As a pixel value assigning scheme a generating means is adapted to generate a voltage characteristic to be applied to the at least one analog line such that the voltage characteristic depends on the pixel values to be assigned to the pixels.Type: GrantFiled: March 15, 2011Date of Patent: July 7, 2015Assignee: SEEREAL TECHNOLOGIES S.A.Inventor: Robert Missbach
