Abstract
A gas light source is disclosed where gas is contained within a graphene cylinder or graphene capsule. Electrodes extending into the graphene cylinder or capsule are stimulated by an electric voltage to emit light. Eight graphene cylinder light sources can be arranged into a seven-segment alpha-numeric display having a decimal point. Different gases produce different colors of light. Three gas light sources having different gases can be arranged into an RGB pixel. An array of RGB pixels can be formed into a display.

A light assembly, comprising:
- a carbon nanotube having an electrode inserted in each end, wherein said electrodes form a gaseous seal with said carbon nanotube at each end of said carbon nanotube;
- and
- a gas sealed within said carbon nanotube by said electrodes, said gas emits light through said carbon nanotube when voltage is applied across said electrodes.
