Claim:
1. A window apparatus, the apparatus comprising: a first layer, wherein the first layer includes a liquid crystal microdroplet (LCMD) display switchable between transparent and opaque states in response to a change in an applied electrical and capable to display a projected image; a second layer coupled to the first layer, wherein the second layer is changeable between a light transmitting configuration and a light blocking configuration; and wherein operational states of the window apparatus including a projection state, an opaque state and a see-through state changeable by combining different states of the first layer and the second layer; wherein in the projection state, the first layer receives a projected image, the second layer is in a closed state or an open state; wherein in the opaque state, the first layer is in an opaque state which may have a function as a light diffuser to bring soft light into a room, or save energy by rejecting heat, such as infrared light; wherein in first see-through state, the first layer is in a transparent state and the second layer is in an open state, the window apparatus can function as a traditional closed window, allowing a viewer to see through from either side of the window and allowing light to pass through; wherein in second see-through state, both the first layer and second layer are in open state, the window apparatus can function as an opened traditional window, allowing both light and air to pass through.
