Abstract

PURPOSE: To prevent the display state of a screen from being disturbed even when a vertical synchronizing signal does not normally arrive by inserting a picture display mode selection circuit between a driving part and a horizontal synchronizing signal input terminal, and at the time of abnormal selective scanning, maintaining a preceding display mode by an output from the selection circuit. CONSTITUTION: The picture display mode selection circuit 10 is inserted between the driving part 4 and the horizontal synchronizing signal input terminal 8, and at the time of abnormally selective scanning, a preceding display mode is maintained by an output from the selection circuit 10. Since the preceding display is left without changing the display on the screen when a vertical synchronizing signal does not normally arrive, a person observing a discharge panel 1 does not feel a sense of physical disorder. When a succeeding vertical synchronizing signal arrives at a normal interval, the picture display can be smoothly switched and no abnormal picture is generated.
