Abstract

PURPOSE: To reduce the number of existing pins by providing a display controller with a selection circuit for selectively outputting a digital picture signal, a horizontal blanking signal and a vertical blanking signal based upon a control signal. CONSTITUTION: An OR circuit 25 to be a circuit for outputting a control signal and a selection circuit 26 to be a selecting means are integrated on the display controller 21 together with a timing circuit for generating a horizontal blanking signal 27 and a vertical blanking signal 28, formation circuits of picture signals 4 to 6, and so on. In the case of supplying horizontal and vertical blanking signals, both the signals 27, 28 outputted from the circuit 26 can be used distinctively from a digital picture signal and the signals 27, 28 can be supplied only by a control signal output pin without exclusively preparing a horizontal blanking signal output pin and a vertical blanking signal output pin. Consequently the number of existing pins can be reduced.
