GASEOUS-DISCHARGE AC DISPLAY PANEL AND ITS CONTROL PROCESS Russian patent published in 2000 - IPC

FIELD: gas-discharge engineering; color video modules. SUBSTANCE: display elements of panel including four display electrodes have their middle electrodes spaced through distance l₁ which is greater than distances l₂ and l₃ between each of middle electrodes and adjacent extreme electrodes; control process includes supply of general recording pulses to one of middle display electrodes and to its adjacent extreme electrode during warm-up period and alternate supply of discharge- maintenance scanning pulses to each pair of display electrodes set up of one middle electrode and adjacent extreme electrode in addressing mode of operation; discharge-maintenance pulses across each pair have similar amplitudes and polarity. Most reliable control of panel is ensured when l₁, l₂, l₃ are chosen from equations with l₂ = l₃ EFFECT: improved reliability of control process due to reduced control voltages. 4 cl, 3 dwg
