Abstract: This application provides a floating optical device, an optical module, and an optical system that are configured to perform floating display. The floating optical device includes a focusing layer, a transmission layer, and a convergence layer that are sequentially stacked in a direction of an optical axis. The focusing layer includes a plurality of focusing units that are periodically arrayed. The convergence layer includes a plurality of convergence units that are periodically arrayed. The plurality of focusing units and the plurality of convergence units are in a one-to-one correspondence in the direction of the optical axis. In the focusing unit and the convergence unit that correspond to each other, the focusing unit is configured to modulate incident light rays, to concentrate incident light rays that are parallel to each other to a same incident concentration point on the incident surface of the transmission layer.

Abstract: A backlight display assembly and an apparatus on which the backlight display assembly is deployed are disclosed, to effectively improve light utilization of the backlight display assembly. The backlight display assembly includes a light filter layer, a spectrum splitting layer, and a backlight layer. The light filter layer includes a plurality of light filter units, and each light filter unit includes a plurality of different light filters. The spectrum splitting layer is disposed on one side of the light filter layer, and the spectrum splitting layer and the light filter layer are spaced from each other. The spectrum splitting layer includes a micro-nano structure including a plurality of strip structures, and an arrangement direction of the plurality of strip structures is consistent with an arrangement direction of the plurality of different light filters.
