Abstract
A pulse driven self-shift plasma display panel characterized by having meander type shift channels for shifting a discharge spot. Each meander type shift channel is composed of an array of discharge cells defined in the discharge gap at the crossing points of electrodes arranged on parallel substrates, the electrodes on one substrate being oriented generally transversely to those on the other substrate, and barrier structure for determining the meander route being provided. Data in the form of a discharge spot is written in at one end of a shift channel and is shifted by the pulse shift voltages with various phases over the meander route for display at the desired positions. The barrier structure may also be formed using photo-luminescent phosphor material to create desired colored display effects.
