  • Patent number: 10739613
    Abstract: A display system is provided that combines the use of a display element with a beamsplitter and at least one retroreflector to provide an image (2D or 3D depending upon the output image from the display element) that appears to be floating in space some distance from the beamsplitter. For example, light that is bounced off/reflected and/or that is transmitted through the beamsplitter may be reflected from the reflective surface of the retroreflector toward the beamsplitter. The beamsplitter directs this light, through reflection or transmission, into a viewing space such that the 2D or 3D image can be viewed by a viewer as it appears to float a distance from the nearest surface of the beamsplitter and, typically, some distance above the ground/floor upon which viewers are walking. The floating image may be relatively bright so that it is viewable in low and brighter light conditions.

  • Patent number: 10636351
    Abstract: A conformable matrix display device is provided with row conductors on the conformable carrier, each for a respective row of the matrix of pixel circuits. Each row conductor has serpentine trajectories in spaces between the pixel circuits in the respective row. Power supply voltage and selection pulse signals are transmitted over the same row conductors. Each row conductor is connected to supply voltage and selection inputs of the pixel circuits in the respective row. Each pixel circuit has a pulse transmission circuit coupled between the selection input and the control input of a de-multiplexing circuit for de-multiplexing data signals on column conductors. In this way the power supply voltage and the selection signal can be supplied making shared use of space between the pixel circuits. Thus the number of conductors in the matrix display device is reduced, which enables a greater distance between the conductors and/or bends in the conductors, which makes the circuit more stretchable and/or bendable.

  • Patent number: 10001654
    Abstract: A display system is provided that combines the use of a display element with a beamsplitter and at least one retroreflector to provide an image (2D or 3D depending upon the output image from the display element) that appears to be floating in space some distance from the beamsplitter. For example, light that is bounced off/reflected and/or that is transmitted through the beamsplitter may be reflected from the reflective surface of the retroreflector toward the beamsplitter. The beamsplitter directs this light, through reflection or transmission, into a viewing space such that the 2D or 3D image can be viewed by a viewer as it appears to float a distance from the nearest surface of the beamsplitter and, typically, some distance above the ground/floor upon which viewers are walking. The floating image may be relatively bright so that it is viewable in low and brighter light conditions.
