ABSTRACT:
There is disclosed a telephone subset which incorporates a high resolution electrophoretic display on the surface of a subset housing. The telephone subset includes a microprocessor which operates under the control of a mode selector. In this manner the display is employed to generate various keyboard formats and operates in conjunction with a position sensitive overlay to enable a subscriber to place telephone calls in a conventional manner when the keyboard display is implemented on the electrophoretic display. The telephone subset in conjunction with various subset buttons which control the mode selector is capable of operating in different modes. Due to the high resolution and large capacity of the display one can now present pages of stored telephone numbers which essentially enables a user to select any number by the use of a movable cursor and by pressing another subset button can immediately dial that number. Other modes provide credit card storage which are accessible and displayed as well as other privacy operative modes which are implemented by the high resolution display, microprocessor and associated circuitry.
