Abstract:
A display of a dot matrix type, comprising a voltage-sensitive medium in connection with primary and secondary groups of intersecting conductive paths,wherein an optical state of the voltage-sensitive medium is changed locally to form a plurality of dot areas when a voltage difference is established by means of said intersecting, conductive paths,wherein a first group of said dot areas is arranged in a substantially uniform pattern of dots to form a primary display area to display alphanumeric signs,wherein a second group of said dot areas is arranged in a predetermined pattern to form an icon area to display predetermined icons, a first display dimension of the dot areas of the second group in one direction being substantially a same size as a first display dimension of the dot areas of the first group in the primary display area, and a second display dimension of the dot areas of the second group being adapted to the shape of the icons in another direction,wherein the primary group of conductive paths passes through both the primary display area and the icon area forming the alphanumeric signs in the primary display area and the icons in the icon area, while at least one conductive path of said secondary group of conductive paths passes through the icon area without passing through the primary display area,wherein the conductive paths of the primary group of conductive paths passing through both the primary display area and the icon area are integrated into the second group of dot areas, andwherein the conductive paths of the primary group of conductive paths passing through both the primary display area and the icon area are formed as straight paths passing through an entire active display area constituted by said primary display area and said icon area.
