Abstract

In a scanning gas panel in which the panel is driven by a three-phase signal, the lines are coupled in multiples of three so that each of the three drive signals addresses one-third of the drive conductors and the display is moved incrementally across the screen.

Gas Panel Conductor Configuration

In a scanning gas panel in which the panel is driven by a three-phase signal, the lines are coupled in multiples of three so that each of the three drive signals addresses one-third of the drive conductors and the display is moved incrementally across the screen.

Considering an embodiment wherein the vertical drive lines are connected in this configuration, two of the three drive lines can be driven from the upper and lower buses and present no problem. However, in connecting a third set of drive lines, it is essential that the terminal pads of this third line be so interconnected as not to affect or short out the associated terminal drive system. One method of accomplishing the interconnection of the metallized pads utilizes stitch bonding, and operates as follows.

Referring to Fig. 1, there is illustrated a typical gas panel assembly prior to seal. The assembly comprises a gas panel having a viewing surface 11, horizontal pads 13 and a drive terminal 15. The vertical drive conductors from buses 17 and 19 are not shown, since they are merely conventional drive lines emanating from a common bus in multiples of three. The terminal pads for the third set of drive lines emanates from pad 15, wherein each of the drive conductors in the third set is identified y dots 21.

Referring hriefly to Fig. 2, a sectional view taken along lines 2, it is noted that the conductor terminal pads 21 are interconnected through a stitch bond conductor...
