Abstract

An electronic device having a display is disclosed which comprises contacts for electrically coupling the display to the circuitry of the electronic device, and a mounting arrangement for removable attachment of the display to the electronic device, such that the display may be removed from the electronic device to be read. The electronic device may be a radio transceiver, and the display may be adapted to display a paging message from a paging receiver associated therewith.

Claims

1. An electronic device including a paging receiver for receiving messages and a display module electrically coupled to said electronic device, said electronic device comprising:

memory means disposed in the display module for storing therein said received messages when the display module is electrically coupled to the electronic device;

means for electrically decoupling the display module from the electronic device; and

means disposed in the display module for operating the display module to display the stored messages of the memory means when electrically decoupled from the electronic device, such that the display module may be utilized to display received messages when electrically disconnected from the electronic device.

2. An electronic device as set forth in claim 1 wherein the electronic device comprises a radio receiver.

3. An electronic device as set forth in claim 1 wherein the electronic device comprises a radio transceiver.

4. An electronic device as set forth in claim 1 including an enclosure for containing the paging receiver;

and magnetic mounting means disposed on said enclosure; and

wherein the display module includes means for magnetically mounting itself to the magnetic mounting means of said enclosure.

5. A paging receiver for receiving messages comprising:

display means electrically attachable to said paging receiver for displaying a received message;

memory means disposed in said display means for storing said received messages when the display means is electrically attached to the paging receiver.

means for electrically detaching said display means from said paging receiver; and

means disposed in said display means for operating said display means in said electrically detached state to display the stored messages of said memory means, thereby rendering the display means operational upon electrically disconnecting said display means from said paging receiver.

6. The paging receiver of claim 5 including an enclosure for containing the paging receiver, and magnetic mounting means disposed on said enclosure;

and wherein said electrically detaching means comprises a plurality of magnets and contacts to securely hold said display means to the magnetic mounting means of said enclosure and make electrical contact with the paging receiver.

7. The paging receiver of claim 5 wherein said operating means includes:

a plurality of controls to selectively display one of the messages of the memory means on said display means.

8. The paging receiver of claim 7 wherein said operating means further includes:

a power source for supplying energy to said memory means, said display means, and to said controls.

9. The paging receiver of claim 8 wherein said power source is rechargeable.

10. The paging receiver of claim 5 comprising:

a second memory means for storing received messages, and means for updating said memory means of said display means with said stored messages of said second memory means when said detachable display means is electrically reattached to the paging receiver.
