Patent ID: 8411344

Claim:
An electrical control light valve apparatus having liquid gallium metal, comprising: a bottom flat plate, the bottom flat plate being a transparent glass; a transparent conductive film being used as a positive electrode (anode) that is located on a top of the bottom flat plate; another conductive electrode film being used as a negative electrode (cathode) that is located on the top of the bottom flat plate; a transparent conductive solution being injected between the bottom flat plate and a top flat plate, the transparent conductive solution being selected from the group consisting of H 2 SO 4 , and HCl; a liquid gallium metal being placed on the cathode transparent conductive film, the liquid gallium metal having a round sphere when a voltage being not applied, and the liquid gallium metal having expanding as like a film when the voltage being applied; and a top flat plate being placed on the top of the transparent conductive solution to form the electrical control light valve apparatus having the liquid gallium metal.
