ABSTRACT:
A driving method of a display apparatus for AC driving display materials such as liquid display and so on to the picture display by the use of an active matrix with switching elements of thin film transistors so that the output signal voltage of the signal driving circuit of the active matrix display apparatus is considerably reduced and the consumption power of the same driving circuit handling the analog signal may be reduced.
