Abstract
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.
