ABSTRACT:
A self shift type gas discharge panel has a display screen with a plurality of shift lines in the vertical direction, and a new driving system is provided for the panel. The display screen is divided horizontally into two areas, an upper part having display rows and a lower part having monitor rows, and these monitor and display rows are configured to allow independent shift operation. Thus, relevant data is written from underneath into the bottom monitor row by a one-data-input-and-refresh method, and when the writing into this monitor row is completed, the data in this single row is scrolled up into the display rows. The configuration makes it possible to write data into a desired position in the monitor rows and to amend easily the data already written, resulting in improved operability.
