Abstract
An artificial window is provided. In one example, the artificial window includes a transparent light emitting diode (LED) display panel, and a directional backlight module located at a back side of the transparent LED display panel. The transparent LED display panel includes multiple first LEDs to display at least one image frame, and the directional backlight module includes multiple second LEDs forming a directional LED array to generate a collimated directional light toward the transparent LED display. In another example, the artificial window includes a display panel to display at least one image frame; and a backlight module located at a back side of the display panel. The backlight module includes a first light source providing backlight for the display panel, and a second light source to generate a collimated directional light.
