1. An electronic shadable window system for building comprising:

  • a first transparent panel, having a first side and a second side;

    a first electrically conductive layer attached to the second side of the first transparent panel;

    a second transparent panel, having a first side and a second side;

    a second electrically conductive layer attached to the second side of the second transparent panel;

    a liquid-crystal display (LCD) material held between the first electrically conductive layer and the second electrically conductive layer, wherein the LCD material is a dyed LCD material; and

    an electrical signal source in electronic communication with the first electrically conductive layer and the second electrically conductive layer, and wherein the dyed LCD material exhibits a greater transparency when no voltage is applied from the electrical signal source, than when a voltage is applied.
