    摘要： A button includes a substrate, a frame body, an optical pressure board assembly and an optical trigger switch. The substrate includes a physical key and a light emitting assembly. The frame body mounted on the substrate accommodates the physical key and the light emitting assembly. A side of the frame body away from the substrate includes an opening. The optical pressure board assembly is slidably arranged in the frame body and covers the physical key and the light emitting assembly. The optical pressure board assembly is adapted to moving in an operating direction towards the substrate to contact the physical key, so the physical key generates a first manipulation signal. The optical pressure board assembly is further adapted to converting a light beam into a three-dimensional optical image. The optical trigger switch is mounted on an outer side of the frame body and adapted to generating a second manipulation signal.

    摘要： A splicing display apparatus for floating image and a multi-layer display device comprising the same are disclosed. The splicing display apparatus comprises: a display module configured to emit, on a display plane thereof, display light constituting a target image; a plurality of optical imaging modules configured to receive the display light to form a floating image in the air; and a one-dimensional scattering screen to scatter light in the y-direction, wherein each of the plurality of optical imaging modules comprises: a first one-dimensional conjugate imaging element to converge light beams from points on the display plane onto the one-dimensional scattering screen in the y-direction; and a second one-dimensional conjugate imaging element to converge light beams from points on the display plane onto a floating image plane different from the plane where the one-dimensional scattering screen is located in the x-direction. The x-direction and the y-direction are orthogonal to a main optical axis of the optical imaging module respectively.

    摘要： According to one embodiment, a display apparatus includes a display device and an image display control circuit. The display device includes a display panel and a light controller. The light controller controls a direction of a light ray emitted from the display panel. The image display control circuit controls the display panel to display an image in which two or more parallax images having different parallax numbers are mixed, on a display surface of the display device. The image display control circuit displays a parallax image having a first parallax number in at least a first area and displays a parallax image having a second parallax number in a second area. The second parallax number is smaller than the first parallax number.
