Abstract
1418037 Matrix displays THOMSON-CSF 21 Dec 1972 [23 Dec 1971] 59262/72 Heading G5C A memory type gas discharge panel is conditioned by non-display cells which surround the areas of the panel used for displaying information and which are energized at a frequency lower than the sustained potential frequency. These cells may also be energized when write signals are applied. When the conditioning and sustain signals are in phase the cells marked with a triangle are energized, when they are out of phase all cells on electrodes EL1 ... EL3 and EC1, EC2 are energized. The panel control circuit includes a decoder 21, pulse generator 23, modulators 24, 25 which supply sustain or write magnitude pulses and interface selection circuits 26, 27. The conditioning signals are generated by a frequency divider 28, shaper and adding circuits 29, 32, 33 and amplifiers 30, 31. The additional conditioning pulses are produced by a coincidence circuit 34 operated when write pulses occur at decoder 21. Square, sinusoidal and trapezoidal wave forms are referred to.
