Abstract

A hidden display may be used in an apparatus to display information to a user. The display hardware is generally hidden within the apparatus and illuminated information appears on an outside surface of the apparatus to display the information. The hidden display may couple light into a display panel from the inside of the apparatus to provide the illuminated information on the outside surface of the display panel. The display panel may provide diffuse reflection of ambient light on the outside of the display panel such that the display hardware is not visible behind the display panel but without providing a mirror-like reflection. The display may be used in a variety of different apparatuses or devices including, but not limited to, clocks and clock audio devices.

Claims (33)

1. A hidden display comprising:

at least one light emitting display element; and

a display panel having an inside surface and an outside surface, the inside surface of the display panel being in contact with the at least one light emitting display element such that light emitted from the light emitting display element is optically coupled into the display panel, the outside surface of the display panel including a display region for displaying illuminated information formed by the light optically coupled into the display panel, wherein the display panel is transparent to at least a portion of the light from the light emitting display element optically coupled into the display panel such that the light from the light emitting display element is visible on the outside surface as the illuminated information, and wherein the display is opaque to ambient light impinging upon the outside surface such that the light emitting display element is not visible behind the outside surface when the light emitting element does not emit light, and wherein the outside surface provides a diffuse reflection of ambient light such that a substantial portion of ambient light is reflected without creating a mirror-like effect.

2. The hidden display of claim 1 further comprising a spring biasing mechanism biasing the at least one light emitting display element into contact with the inside surface of the display panel.

3. The hidden display of claim 2 further comprising a display element carriage carrying the at least one light emitting display element, and wherein the spring biasing mechanism engages the display element carriage to bias the at least one light emitting display element into contact with the inside surface of the display panel.

4. The hidden display of claim 2 wherein the spring biasing mechanism includes at least one compression spring.

5. The hidden display of claim 4 further comprising a display element carriage, and wherein the at least one light emitting display element includes a plurality of light emitting diodes (LEDs) carried by the display element carriage, and wherein the biasing mechanism includes at least four compression springs engaging the display element carriage.

6. The hidden display of claim 1 wherein the at least one light emitting display element includes at least one light emitting diode (LED).

7. The hidden display of claim 1 wherein the at least one light emitting display element includes a segmented display.

8. The hidden display of claim 7 wherein the segmented display includes a plurality of light emitting diode (LED) segments.

9. The hidden display of claim 1 wherein the display panel includes a transparent substrate with a coating forming the inside surface.

10. The hidden display of claim 1 wherein the display panel includes at least a polycarbonate substrate powder coated on the inside surface.

11. The hidden display of claim 10 wherein the polycarbonate substrate includes a textured finish on the outside surface.

12. An apparatus comprising:

a housing;

display driver circuitry; and

a hidden display integral with at least one side of the housing, the hidden display comprising:

at least one light emitting display element; and

a display panel having an inside surface and an outside surface, the inside surface of the display panel being in contact with the at least one light emitting display element such that light emitted from the light emitting display element is optically coupled into the display panel, the outside surface of the display panel including a display region for displaying illuminated information formed by the light optically coupled into the display panel, wherein the display panel is transparent to at least a portion of the light from the light emitting display element optically coupled into the display panel such that the light from the light emitting display element is visible on the outside surface as the illuminated information, and wherein the display is opaque to ambient light impinging upon the outside surface such that the light emitting display element is not visible behind the outside surface when the light emitting element does not emit light, and wherein the outside surface provides a diffuse reflection of ambient light such that a substantial portion of ambient light is reflected without creating a mirror-like effect.

13. The apparatus of claim 12 wherein the at least one light emitting display element includes at least one light emitting diode (LED).

14. The apparatus of claim 12 further comprising a seal between the display panel and the housing to prevent light from the light emitting display element from passing out of the housing between the display panel and the housing.

15. The apparatus of claim 12 further comprising at least one circuit board mounted within the housing proximate the display panel, wherein the circuit board includes at least the display driver circuitry, and wherein the light emitting display element is secured to the circuit board.

16. The apparatus of claim 15 further comprising a spring biasing mechanism between the circuit board and the light emitting display element, wherein the biasing mechanism biases the light emitting display element into contact with the display panel.

17. The apparatus of claim 14 wherein the display panel includes a polycarbonate substrate with a powder coated inside surface and a textured finish on the outside surface.

18. A clock comprising:

a housing;

control circuitry located within the housing configured to control at least clock functions and display functions; and

a hidden display integral with at least one side of the housing, the hidden display comprising: at least one light emitting display element; and a display panel having an inside surface and an outside surface, the inside surface of the display panel being in contact with the at least one light emitting display element such that light emitted from the light emitting display element is optically coupled into the display panel, the outside surface of the display panel including a display region for displaying illuminated information formed by the light optically coupled into the display panel, wherein the display panel is transparent to at least a portion of the light from the light emitting display element optically coupled into the display panel such that the light from the light emitting display element is visible on the outside surface as the illuminated information, and wherein the display is opaque to ambient light impinging upon the outside surface such that the light emitting display element is not visible behind the outside surface when the light emitting element does not emit light, and wherein the outside surface provides a diffuse reflection of ambient light such that a substantial portion of ambient light is reflected without creating a mirror-like effect.

19. The clock of claim 18 further comprising at least one speaker, and wherein the control circuitry is configured to control audio functions.

20. The clock of claim 18 further comprising:

at least one circuit board mounted within the housing proximate the display panel;

a display element carriage including a segmented LED display, wherein the display element carriage is secured to the circuit board; and

a spring biasing mechanism between the circuit board and the display element carriage, wherein the biasing mechanism biases the segmented LED display into contact with the display panel.
