  • Patent number: 12124063
    Abstract: Certain aspects of the present disclosure provide techniques for a front panel for a video display system. According to disclosed embodiments, a substrate is fabricated to incorporate materials having desired functional properties, such as the blocking of ultraviolet visible (UVV) laser light, and near infrared light, into the substrate material. After extrusion of the substrate with desired functional properties, an anti-glare hardcoat may be spray-coated to the front and back of the front panel to provide anti-glare as well as anti-stiction properties.

  • Publication number: 20240329512
    Abstract: A display system includes a display screen, where the display screen includes one or more transparent substrates, such as glass, plastic, or the like, a plurality of transparent adhesive pads, a plurality of white ink or adhesive deposits (e.g., a UV cured adhesive), a plurality of light absorbing material, such as black ink deposits, a plurality of gaskets, a color filter/mirror film, and a plurality of phosphors. The display screen may additionally include a thin anti-glare layer. The plurality of transparent adhesive pads and the thin anti-glare layer provide support to the plurality of phosphors, such that the plurality of phosphors are not in direct contact with the one or more transparent substrates and/or the color filter/mirror film. The plurality of white ink deposits may prevent light diffusion from one phosphor to another phosphor and the plurality of light absorbing material, such as black ink deposits, aids in increasing contrast between the phosphors.

  • Patent number: 11961436
    Abstract: A display system includes a display screen, a light source to generate a light beam to be modulated in accordance with image data, and a beam scanning module to receive the light beams and to direct the light beam onto an associated display region of the display screen. The beam scanning module includes a resonant scanning mirror configured to scan the light beam along a first scanning direction across the associated display region, and a polygon scanning mirror to scan the light beam along a second scanning direction across the associated display region.

  • Publication number: 20230267863
    Abstract: The present disclosure generally relates to micro-ribbon structures used in display systems and methods of fabrication thereof. Individual fibers are made using an extrusion process whereby a core surrounded by an ink portion is extruded to create an individual fiber. The ink portion may include both an inner portion that is in contact with the core and an outer shell portion over the inner portion. The individual fibers are then bonded to adjacent fibers to create micro-ribbon structures. The micro-ribbon structures are of one color and spaced from adjacent micro-ribbon structures of a different color by a light blocking fiber. The micro-ribbon structures are each bonded to the light blocking fiber to create the color stripes used in the display system.
