Abstract

An EL display is provided with EL segments which are individually illuminable and which include one or more complete function key images and/or fragments of complete function key images. One or more of the EL segments may thus be illuminated to present multiple, different user interfaces each having one or more complete function key images. A complete function key image presented as part of a user interface may be a complete key image that was included as part of an illuminated EL segment or may be formed by a combination of key image fragments included as part of multiple illuminated EL segments.

Claims

1. A remote control, comprising:

a plurality of keys in a key matrix; and

an electroluminescent (EL) display comprising a plurality of flexible (EL) segments disposed in cooperating relation above the key matrix, each EL segment being individually illuminable and each EL segment having a plurality of image fragments such that the plurality of EL segments are illuminable in various combinations to cause interleaved ones of the plurality of image fragments of illuminated EL segments to be combined in various combinations to form various complete images over corresponding ones of the plurality of keys in the key matrix whereby the remote control is provided with the ability to have various remote control user interfaces.

2. The remote control as recited in claim 1, wherein a remote control user interface displays images representative of logical groupings of function keys.

3. The remote control as recited in claim 2, wherein the logical groupings of functions keys comprise one or more of transport control function keys, numerical function keys, and menu control function keys.

4. The remote control as recited in claim 1, wherein the EL segments are illuminated as a function of a selected operational mode of the remote control.

5. The remote control as recited in claim 4, wherein the EL segments are illuminated as a function of a selected remote control user interface page within the selected operational mode of the remote control.

6. The remote control as recited in claim 1, wherein the complete images have the appearance of being formed through use of a dot matrix display.

7. An electroluminescent (EL) display comprising a plurality of flexible, individually illuminable EL segments disposed in cooperating relation wherein each EL segment has a plurality of image fragments such that the plurality of EL segments are illuminable in various combinations to cause interleaved ones of the plurality of image fragments of illuminated EL segments to be combined in various combinations to form various complete images whereby the various complete images are presentable in substantially the same spot on the EL display.

8. The EL display as recited in claim 7, wherein at least one of the plurality of EL segments further has a complete image.

9. The EL display as recited in claim 7, wherein the complete images have an appearance as if formed through the use of a dot-matrix display.

10. The EL display as recited in claim 7, wherein the EL display is included as part of a touch-screen panel.

11. The EL display as recited in claim 10, wherein the EL display is disposed over a key switch matrix to form the touch-screen panel.

12. The EL display as recited in claim 11, wherein the key switch matrix comprises a plurality of domed switches.

13. The EL display as recited in claim 7, wherein at least one of the image fragments of the plurality of EL segments comprises a non-contiguous portion of the EL display.

14. The EL display as recited in claim 7, wherein the spot on the EL display in which the various complete images are presentable comprises an area generally over a single key switch of the key switch matrix.
