Abstract

A folded type mobile terminal apparatus is comprised of a receiving section, a main display unit, an external display unit, a driver section and a control circuit. The receiving section receives a call or an e-mail from a counter end. The main display unit is provided on an inner surface exposed when the mobile terminal is in an opened state, and the external display unit is provided on an outer surface exposed when the mobile terminal is in a closed state. The driver section drives the main display unit and the external display unit. The control circuit controls the driver section such that data relating to the reception of the call or the e-mail and data of the received call or e-mail are displayed on the main display unit displays in the opened state of the mobile terminal and on the external display unit in the closed state of the mobile terminal.
