Abstract
A miniature high resolution plasma display suitable for integration on a semiconductor chip in combination with other circuitry is comprised of two crossed sets of conductors which are arranged on a first substrate to form an array of crosspoints. The two conductors at each crosspoint are a preselected distance apart and separated by a hollow cavity. An array of vertical tubes in a second substrate is spaced so as to correspond to the array of crosspoints. The second substrate is supported in alignment with the first so that the open end of the tubes oppose the cavity at each crosspoint. The tubes and cavities are filled with a pressurized gas and the assembly is sealed with a transparent, electrically conducting coverplate. When a voltage greater than or equal to the Paschen minimum firing voltage is applied across the cavity at a crosspoint, a plasma is created. Ions in the plasma spread from the cavity into the tube in response to a voltage that is applied to the cover plate. The charged particles in the plasma combine within the tube to generate light.
