Abstract
The present invention discloses an electrical control light valve apparatus having liquid gallium. The invention comprises the transparent glass as a substrate, ITO transparent conductive film as the electrodes, the liquid gallium as the valve located on the ITO transparent conductive film, and the partial-transparent glass is located on the top of the electrical control light valve apparatus.
Claims1
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 H2SO4, 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.
