FIG. 1 illustrates one particular embodiment of a window unit in accordance with the invention. The window unit 100 includes a window frame 110. The window frame 110 defines a window frame perimeter 120. A window 130, 135 is located within the frame perimeter 120. The window frame 110 may include a sash frame, a casement frame or a frame of any window or patio door type or combination. The window frame 110 may include a frame surrounding window glass, a sash frame, a casement frame, or a frame of any window or patio door type or combination.
The window unit 100 illustrated in FIG. 1 is a bay window having a plurality of windows, including, a main display window 135 between two side windows 130. However, the window unit 100 may, for example, be capable of being opened or closed. The window 100 may be, for example, a picture window, a bay window, bow window, projection window, a double-hung window, a skylight, egress window, an awning window, a casement window, a gliding window, and the like.
The window frame 110 may include two pair of opposed frame members. A first pair of opposed frame members includes a bottom frame member 111 and a top frame member 112 and can be oriented along a horizontal rigid frame axis. A second pair of opposed rigid frame members includes a first side frame member 113 and a second side frame member 114 can be oriented along a vertical frame axis. The four frame members 111, 112, 113, 114 can generally form a square or rectangle shape. However, the window frame may be any shape.
The window 135 includes a display surface 140 adapted to receive a display image. The main display window 135 and the two side windows 130 can transform from a first transparent state to a second increased opacity state for receiving the display image on the display surface 140. Any means of increasing the opacity of transparent materials may be used such as, for example, polymer dispersed liquid crystal technology. Opacity is the relative capacity of matter to obstruct the transmission of radiant energy or light.
Polymer dispersed liquid crystals may be sandwiched between two pieces of conducting glass. The conducting glass may be a portion of, or the entire window 130, 135. Polymer dispersed liquid crystals operate on the principle of electrically controlled light scattering. When electricity is not applied to the window 130, 135, the liquid crystal droplets are randomly orientated, creating an increased opacity state. When electricity is applied, the liquid crystal droplets align parallel to the electric field and light passes through, creating a more transparent state.
The window unit may include a display image source 150 disposed in the window frame 110. The display image source 150 can be located in the top frame member 112, the bottom frame member 111, the first side frame member 113 or the second side frame member 114. Alternatively, more than one display image source 150 can be located in the window frame 110 and be located in one or more frame member 111, 112, 113, 114. The display image source 150 may be, for example, a projector.
The display image source may project an image on the display surface 140 of the window 135. If the window unit 100 is installed in a structure, the display surface 140 of the window 135 may be an interior window surface for viewing images within the structure or the display surface 140 of the window 135 may be an exterior window surface for viewing images outside the structure.
The display image source 150 may be a heads-up display that projects onto the display surface 140 from below the window frame 110.
The window unit 100 may also include a speaker element 190. The speaker element 190 may be disposed in one or more of the windows 130, 135. The speaker element 190 can be disposed in the main display window 135, one or both side windows 130 or in both the main display window 135 and both side windows 130. The speaker element 190 can produce sound in response to an audio signal. The audio signal may be an analog signal, a digital signal or an analog and digital signal, and the like. The speaker element 190 can be located on or in the window 130, 135. The speaker element 190 may operate in cooperation with the display image source 150 to provide sound to accompany the display images.
