PURPOSE: An active matrix display is provided to decrease power consumption, and to operate through a portable battery by updating or refreshing graphic data simply without demand for refreshing the entire active matrix in displaying only graphic data. CONSTITUTION: An active matrix display is composed of an active matrix array of pixels divided into first and second sets, and pixels(35) of the first set are refreshed in the conventional active matrix method by a first refreshing arrangement(M1,6,7). Pixels(36) for displaying a graphical feature such as an icon overlaid on the active matrix display image have a second refreshing arrangement to allow the icon pixels of each icon to be switched to the same state, such as maximum black or maximum white. The icon pixels have the first refreshing arrangement to be used either as part of the active matrix for displaying arbitrary data or when selected as such, for overlaying the icon image on the arbitrary image data.
