Abstract
A display of dot matrix type is used in a portable telephone. The display is divided into a primary display area to show alphanumeric signs and the like, and into an icon area to show predetermined icons. Both display areas show signs by selectively marking a plurality of dots. The primary display area (the dot matrix area) is a so-called graphic display, in which the dots are regular and may be combined to form arbitrary signs. In the icon display area, the dots are shaped according to the icons. The dots are hereby icon-specific, and their irregular shape occurs in practice by slitting the icon concerned in the transverse direction. The icon area will hereby electrically serve as one or more edge rows in the dot matrix area.
