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.

Claims

1. A telephone subset apparatus for use in providing high quality data displays, comprising:

a telephone subset including a housing having a telephone handset coupled thereto,

a high resolution display panel means mounted on said housing and capable of being accessed by an X-Y addressing means to display graphic data in a plurality of lines,

microprocessor means coupled to said high resolution display panel means and operative to cause said panel means to provide a graphic presentation of a telephone keyboard arrangement according to said X-Y addressing means,

position sensitive means responsive to user position coupled to said high resolution display panel means and operative when accessed solely by exerted pressure to produce a telephone number output signal as dialed by a user employing said graphic telephone keyboard presentation as a guide for selecting said signal.

2. The telephone subset apparatus according to claim 1, wherein said display panel means includes an electrophoretic display.

3. The telephone subset apparatus according to claim 1, wherein said microprocessor means includes an X decoder means coupled to said high resolution display panel means addresses by said microprocessor means to generate X data for said high resolution display means and a Y decoder means coupled to said high resolution display panel means and addressed by said microprocessor means to generate Y data for said display panel means.

4. The telephone apparatus according to claim 1, wherein said microprocessor means includes first storage means coupled thereto and operative to store data indicative of various graphic keyboard presentations to enable a user to dial a telephone number based on any selected one of said keyboard presentations.

5. The telephone subset apparatus according to claim 4, further including means coupled to said handset and operative to provide a control signal when said handset is lifted off hook.

6. The telephone subset apparatus according to claim 5, including means coupled to said microprocessor means and responsive to said control signal to cause said microprocessor means to generate any one of said various graphic keyboard presentations as stored.

7. The telephone subset apparatus according to claim 6, further including interface means coupled to said display panel means for coupling said display panel means to a telephone line.

8. The telephone subset apparatus according to claim 7, wherein said interface means further includes a dialing generator coupled to said position sensitive means and operative to provide telephone dialing signals to said telephone line.

9. The telephone subset apparatus according to claim 4, further including a plurality of actuatable keys mounted on the top surface of said housing and coupled to a mode selector means included in said microprocessor means for operating said microprocessor means in any one of a plurality of modes, according to the selection of an associated key for each said mode.

10. The telephone subset apparatus according to claim 9, further including second storage means operative to store therein a plurality of telephone numbers indicative of called parties, said second storage means accessed by a first one of said associated keys to cause said high resolution display panel means to display a first plurality of stored numbers simultaneously thereon, and cursor means associated with said high resolution display panel means and operative to be movably aligned adjacent each number as displayed under control of said user by at least a second one of said keys to enable a user to select any one of said displayed numbers, and means coupled to a third one of said keys to cause the number aligned with said cursor means to be dialed.

11. The telephone subset apparatus according to claim 10, wherein said plurality of numbers as stored are displayed in consecutive display presentations to thereby store a large directory of telephone numbers which are displayed in groups of numbers on a page-to-page basis.

12. The telephone subset apparatus according to claim 10, further including third storage means coupled to said microprocessor means and operative to store therein a plurality of credit card numbers associated with a user of said subset and accessible by means of a fourth associated key to provide said user with a display indicative of said credit card numbers.

13. The telephone subset apparatus according to claim 12, further including means coupled to said display and operative when said handset is on hook to provide an array of separate characters wherein a user can access said third storage means only by first selecting a given set of characters in said array of separate characters

14. The telephone subset apparatus according to claim 4, wherein said storage means includes a ROM and a RAM.

15. The telephone subset apparatus according to claim 1, further including means coupled to said display means for generating a display of telephone usage.

16. The telephone subset apparatus according to claim 7, wherein said interface means includes means for receiving facsimile transmissions from said telephone line and for converting said transmissions, to graphic data for display by said display panel means.

17. The telephone subset apparatus according to claim 16, further including a data buffer means coupled to said telephone line for storing received data prior to processing the same said data buffer means coupled to said microprocessor means.

18. The telephone subset apparatus according to claim 17, further including ring-back detector means coupled to said telephone line and operative to provide a control signal when a connection is made between said subset and a called party by detecting ring back, with said detector coupled to said microprocessor means to enable said microprocessor means to ready said subset for the receipt of data from said called party.

19. The telephone subset apparatus according to claim 1, wherein said position sensitive means includes a pressure sensitive overlay which overlay is positioned over said display means and provides position sensitive output signals according to the area of said display means contacted by a user exerting pressure thereat.

20. The telephone subset apparatus according to claim 1, wherein said microprocessor means includes character generator means operative to convert digital data as stored to alpha numeric character data for addressing said high resolution display panel means.

21. The telephone apparatus according to claim 1, wherein said microprocessor means includes means which is operative to cause said panel means to provide a graphic presentation of a telephone keyboard arrangement which is a substantially random keyboard presentation.

22. The telephone apparatus according to claim 1, which further comprises random generator means coupled to said microprocessor means and operative to cause said microprocessor means to cause said panel to provide a graphic presentation of a telephone keyboard arrangement which is a substantially random keyboard presentation.
