AC GAS PANEL AND ITS CONTROL PROCESS Russian patent published in 2001 - IPC

FIELD: gas- discharge engineering; information display on ac gas panels. SUBSTANCE: each pixel has four display electrodes; distance l₁ between middle display electrodes is shorter than distances l₂ and l₃ between each of . middle electrodes and closest extreme ones; l₂ may equal l₃ and l₂ may be shorter than distance l₃ between closest edges of adjacent extreme electrodes of two adjacent pixels. Panel control is effected by feeding general write pulses to middle display electrodes during warm-up period, control pulses, to control electrodes and to middle display electrode most distant from extreme display electrode during addressing mode, and discharge maintenance pulses, to same middle display electrode and to extreme display electrodes during display mode, initially to extreme display electrode closest to this middle one. EFFECT: enhanced reliability of control. 4 cl, 3 dwg
