Abstract

In one form of the invention, an apparatus for visually displaying a non-volatile message includes an integrated circuit having first circuitry. The apparatus also includes a package for the integrated circuit and a display affixed to the integrated circuit package. The first circuitry is coupled to the display and operable to be coupled to an electronic device by pins of the integrated circuit package and to write a non-volatile, visual image via the display responsive to receiving a message from the electronic device.

Claims

1. An apparatus for visually displaying a non-volatile message for an electronic device, wherein the apparatus comprises:

an integrated circuit having first circuitry;

a package for the integrated circuit; and

a display affixed to the integrated circuit package, wherein the first circuitry is coupled to the display and operable to be coupled to the electronic device by pins of the integrated circuit package and to write a non-volatile, visual image via the display responsive to receiving a message from the electronic device, wherein the display comprises an array having a number of segments, and writing the non-volatile, visual image comprises the first circuitry selectively driving at least one segment of the array, and wherein a thermally-sensitive label is held proximate to the at least one segment and the at least one segment generates heat responsive to the driving, the heat being effective for permanently changing an appearance of a portion of the label corresponding to the at least one segment.

2. The apparatus of claim 1, wherein the first circuitry comprises logic circuitry operable, responsive to the electronic device powering up, to automatically determine a version for the electronic device and write an indication of the version via the display.

3. The apparatus of claim 1, wherein the first circuitry comprises logic circuitry operable to determine an amount of a consumable resource remaining for the electronic device and write an indication of the remaining amount via the display.

4. The apparatus of claim 3, wherein the electronic device comprises battery operated circuitry, and the consumable resource comprises battery operating time.

5. The apparatus of claim 3, wherein the electronic device comprises a disposable cell phone and the consumable resource comprises calling time.

6. An apparatus for visually displaying a non-volatile message for an electronic device, wherein the apparatus comprises:

a display affixed to the electronic device; and

first circuitry affixed to the electronic device and communicatively coupled to the electronic device and the display, the first circuitry being operable to write a non-volatile, visual image via the display responsive to receiving a message from the electronic device, wherein the display comprises an array having a number of segments, and writing the non-volatile, visual image comprises the first circuitry selectively driving at least one segment of the array, and wherein a thermally-sensitive label is held proximate to the at least one segment and the at least one segment generates heat responsive to the driving, the heat being effective for permanently changing an appearance of a portion of the label corresponding to the at least one segment.

7. The apparatus of claim 6, wherein the electronic device comprises a packaged integrated circuit, the display being affixed to the package.

8. The apparatus of claim 6, wherein the electronic device comprises a printed circuit board to which the display is affixed.

9. The apparatus of claim 6, wherein the first circuitry comprises logic circuitry operable, responsive to the electronic device powering up, to automatically determine a version for the electronic device and write an indication of the version via the display.

10. The apparatus of claim 6, wherein the first circuitry comprises logic circuitry operable to determine an amount of a consumable resource remaining for the device and write an indication of the remaining amount via the display.

11. The apparatus of claim 10, wherein the electronic device comprises battery operated circuitry, and the consumable resource comprises battery operating time.

12. The apparatus of claim 10, wherein the electronic device comprises a disposable cell phone and the consumable resource comprises calling time.

13. A method for visually displaying a non-volatile message for an electronic device, the method comprising the steps of:

receiving a message from the electronic device by first circuitry affixed to the device;

writing, responsive to the message, a non-volatile, visual image by the first circuitry via a display affixed to the device, wherein the display comprises an array having a number of segments, and writing the non-volatile, visual image comprises the first circuitry selectively driving at least one segment of the array, and the method includes the step of holding a thermally-sensitive label proximate to the at least one segment, and wherein the at least one segment generates heat responsive to the driving and permanently changes an appearance of a portion of the label corresponding to the at least one segment.

14. The method of claim 13, wherein the electronic device comprises a packaged integrated circuit, the display being affixed to the package.

15. The method of claim 13, wherein the electronic device comprises a printed circuit board to which the display is affixed.

16. The method of claim 13, wherein the first circuitry comprises logic circuitry and the method comprises:

automatically determining, by the logic circuitry in response to the electronic device powering up, a version for the electronic device; and

writing an indication of the version via the display by the logic circuitry.

17. The method of claim 13, wherein first circuitry comprises logic circuitry and the method comprises:

determining, by the logic circuitry, an amount of a consumable resource remaining for the device; and

writing via the display, by the logic circuitry, an indication of the remaining amount.

18. The method of claim 17, wherein the electronic device comprises battery operated circuitry, and the consumable resource comprises battery operating time.

19. The method of claim 17, wherein the electronic device comprises a disposable cell phone and the consumable resource comprises calling time.

20. An apparatus for visually displaying a non-volatile message for an electronic device, wherein the apparatus comprises:

a display affixed to the electronic device; and

first circuitry affixed to the electronic device and communicatively coupled to the electronic device and the display, the first circuitry being operable to write a non-volatile, visual image via the display responsive to receiving a message from the electronic device, wherein the display comprises an array having a number of segments, and writing the non-volatile, visual image comprises the first circuitry selectively driving at least one segment of the array, wherein a thermally-sensitive label is held proximate to the at least one segment and the at least one segment generates heat responsive to the driving, the heat being effective for permanently changing an appearance of a portion of the label corresponding to the at least one segment.

21. The apparatus of claim 20, wherein the first circuitry comprises logic circuitry operable, responsive to the electronic device powering up, to automatically determine a version for the electronic device and write an indication of the version via the display.

22. The apparatus of claim 20, wherein the first circuitry comprises logic circuitry operable to determine an amount of a consumable resource remaining for the device and write an indication of the remaining amount via the display.
