Claims

[Scope of utility model registration request]

A matrix circuit comprising a display section consisting of a plurality of digits, a plurality of digit lines and a plurality of segment lines, and display elements for the segments constituting each digit of the display section are provided between the intersections of these two lines. comprising: at least one of the display units;
one digit does not provide a display using a display element connected to the intersections of the digit line of that digit and all of the segment lines, and at least one other digit of said display provides only a limited type of display. The multi-digit dynamic drive type multi-digit display device is provided with circuit means for making the digit lines of the at least two digits common and driving the display segment of the other digit using a segment line that is not used in one digit. A dynamically driven multi-digit display device characterized by:
