Bidirection shift plasma display requiring less than 20 drivers

A bidirection shift technique has been successfully demonstrated on a 512 × 120 cell array of a standard ac plasma panel. The key features of the bidirection shift technique are: electron transport for efficient information transfer, preset wall voltage for select-shift and timed select-erasure for automatic error clearing. The technique reduces the number Of line drivers to 2 four-phase drivers and 7 line drivers. A shifting speed up to 800 characters/s has been achieved with good operating voltage margins.
