Abstract

A method for repairing open conductors in plasma display panels is disclosed in U.S. Patent 4,304,450. The repair wires which provide an alternate electrical drive source for the length of display line beyond the physical opening in the conductor array are part of a cable harness.

Spare Conductors in Plasma Display Panel

A method for repairing open conductors in plasma display panels is disclosed in U.S. Patent 4,304,450. The repair wires which provide an alternate electrical drive source for the length of display line beyond the physical opening in the conductor array are part of a cable harness.

The present article describes an improvement for automating open conductor repair. The method consists of replacing the cable harness that is normally positioned around the panel with spare conductors fabricated as part of the artwork pattern on each plate. With spare conductors in the artwork, only short planar jumper wires are required along the panel aprons to complete the repair circuit. This makes an automatic repair tool feasible, because all wire runs are now in one direction and in one plane on each apron.

Referring to the drawing, there is illustrated a gas panel front plate 1 having an open display line 2, terminated with repair land 3 at one end and repair land 5 at the opposite end. Beyond but connected to repair land 3 is an external land 7. The conductors in both conductor arrays have repair land terminals on opposite sides thereof. The external lands, such as 7, are used for connection to the line drivers which, in turn, are alternated from opposite ends of the horizontal array in the illustrated embodiment. Also shown on the top and bottom areas are spare conductors 9, located adjacent to the seals outside the normal viewing area...
