ABSTRACT OF THE DISCLOSURE A high-brightness image display panel utilizing highly efficient gas discharge cells is disclosed. Each cell comprises means defining a shallow, substantially rectangular elongated cavity having a high surface to volume ratio, with a cavity wall extending lengthwise of the cavity and oriented such that a phosphor coating is exposed to the viewed side of the cell. The gas filling the cavity comprises a mixture of helium and mercury vapor. A positive column is established within the cavity. The combination of the gas, gas pressure and cavity geometry operate together to increase the energy of free electrons within the positive column and thereby increase cell efficiency and brightness.
