ABSTRACT:
An active-matrix image display device which includes n shift registers, analog switches for sampling video input signals and a data-signal-line driving circuit to which n series of clock signals and n.times.m series of video input signals are input, and controls the analog switches according to the result of a logic operation of output pulses from successive l stages in the shift registers. A scanning circuit without using shift registers. Here, n is an integer not smaller than one, m and l are integers not smaller than two. With the image display device, sampling of video signals is surely executed without increasing the number of shift registers. It is thus possible to reduce the size and weight of the image display device and to decrease the defect rate thereof. Moreover, the scanning circuit achieves a higher yield compared with a conventional scanning circuit using a shift register.
