ABSTRACT:
A scanning circuit operates at a driving speed approximately twice the conventional speed when clock signals having the same frequency as those in the prior art are supplied. By alternately driving the switches in even-numbered and odd-numbered transfer stages T1to Tn, the input side and the output side of each transfer stage are simultaneously made high in order of T1, T2, . . . and Tn. Logical AND circuits are connected to the even- and odd-numbered stages to output pulse signals for scanning at intervals shorter than the clock period.
