1.   In this variant of a conventional liquid-crystal display, a thin layer of plasma gas behind the screen receives an electrical charge that activates the colored crystals.

2.   Sharp is moving in that direction, and so is Sony, with an adaptation of liquid crystal technology that uses plasma gas as a catalyst.

3.   The back of a screen is coated with a thin layer of thousands of tiny chambers of ionized plasma gas.

4.   The patent uses plasma gas to create images on glass.
