ABSTRACT:
An analog sampling circuit of a signal electrode driver of a matrix type liquid crystal device includes two pairs of FETs. During a first half of a select period of a scanning electrode, a first pair of serially connected FETs are deactuated while actuating one FET of the second pair of FETs to provide a signal voltage to a signal electrode of the display device. On the other hand, during the latter half of the select period, the first pair of FETs are actuated to provide an image signal voltage to the signal electrode.
