Abstract
A display apparatus having an X-Y matrix type display panel with data and scanning electrodes has a driving circuit for driving the scanning electrodes which driving circuit is divided into two portions. One portion is for odd-numbered scanning electrodes and another portion is for even-numbered scanning electrodes. By actuating the odd-numbered electrode driving circuit and the even-numbered electrode driving circuit alternately, in a staggered fashion, a conventional single electrode scanning mode is obtained. However, when the odd-numbered electrode driving circuit and the even-numbered electrode driving circuit are simultaneously actuated, a dual electrode scanning mode is obtained. Thus, two diffrent scanning modes can be obtained by providing an appropriate display mode switching signal to the odd-numbered and even-numbered electrode driving circuits.
