Publication number: 20220311984Abstract: A system for rendering three-dimensional image content for a multi-focal display device. The system includes a first processing sub-system configured to divide the three-dimensional image content into a plurality of virtual depth planes, associate each of the plurality of virtual depth planes with one of a first set of displays and a second set of displays of the multi-focal display device, and generate a first array including the plurality of virtual depth planes. The system also includes a transmission sub-system configured to provide a data channel for transmission of the generated first array. The system further includes a second processing sub-system configured to receive the generated first array and to render the three-dimensional image content in the multi-focal display device based thereon.Type: ApplicationFiled: March 26, 2021Publication date: September 29, 2022Applicant: Lightspace Technologies, SIAInventors: Ilmars Osmanis, Roberts Zabels, Kriss Osmanis, Roberts Gotlaufs, Marcis Greitans, Kristians Slics, Elza Lina Linina

Publication number: 20220310037Abstract: A head-mounted display system for reducing motion-to-photon latency. The head-mounted display system includes a head-mounted display apparatus including a display driver to drive an image on a display, a tracking system to obtain a pose data, a communication interface to form communication between the head-mounted display apparatus and a remote rendering unit, and a display processor configured to collect a first pose data at a first moment of time and a second pose data at a second moment of time and provide the collected pose data to the remote rendering unit, collect a third pose data at a third moment of time, receive a second initial image from a remote rendering unit, use the third pose data to form a second first initial image from the second initial image and receive V-sync signal from the display driver and thereafter provide the second initial image to the display driver.Type: ApplicationFiled: March 26, 2021Publication date: September 29, 2022Applicant: Lightspace Technologies, SIAInventors: Ilmars Osmanis, Roberts Zabels, Kriss Osmanis, Roberts Gotlaufs, Marcis Greitans, Kristians Slics, Elza Lina Linina

Patent number: 11425343Abstract: A display system for presenting three-dimensional images. The display system includes projection unit including projection subassemblies, wherein each projection subassembly includes array of point-like light sources, spatial light modulator and controller; projection screen; and processor. The processor is configured to: process three-dimensional data pertaining to a scene to generate image data of three-dimensional image; and display three-dimensional image, via projection subassemblies of the projection unit, wherein, in each of projection subassemblies, the controller is configured to multiplex operations of individual point-like light sources of the array and the spatial light modulator in a time-sequential manner, based on the image data of three-dimensional image, to display a plurality of segments of three-dimensional image sequentially.Type: GrantFiled: June 16, 2020Date of Patent: August 23, 2022Assignee: Lightspace Technologies, SIAInventors: Ilmärs Osmanis, Roberts Zabels, Kri{hacek over (s)}s Osmanis, Märtiņ{hacek over (s)} Narels, Uǵis Gertners, Rendijs Smukulis, Märcis Greitäns

Publication number: 20220163816Abstract: A display apparatus for presenting three-dimensional imagery, including an optical combiner having a first side, a second side, a third side and a fourth side. The second side is opposite to the first side and the fourth side being is opposite to the third side. Optical combiner further includes a first semi-transparent reflective portion arranged to reflect light incoming from the first side towards the fourth side and a second semi-transparent reflective portion arranged to reflect light incoming from the second side towards the fourth side. Light incoming from the third side passes through the first semi-transparent reflective portion and the second semi-transparent reflective portion towards the fourth side.Type: ApplicationFiled: February 14, 2022Publication date: May 26, 2022Applicant: Lightspace Technologies, SIAInventors: Ilmärs Osmanis, Kri{hacek over (s)}s Osmanis, Märtin{hacek over (s)} Narels, Rendijs Smukulis, Märcis Greitäns, Roberts Zabels
