ABSTRACT:
A high brightness panel display (20) includes a plurality of discrete gas discharge cells (24) sealed against a phosphor-carrying front panel section (26) and operable to produce a high brightness display. Gas discharges are ignited and extinguished in selected gas discharge cells (24) to excite or extinguish associated pixels P.sub.m,n that are formed in portions of phosphor strips (35) on the front panel section (26). The gas discharge cells (24) are controlled with electrodes that are common to several cells but driven so that a gas discharge can be ignited or extinguished in one cell without effecting any other cell. Consequently, the pixels may have a 100% per-frame duty cycle, thereby producing very high brightness.
