Abstract

An image display device, including: a luminous display having a light emitting face for providing a luminous image; and a reflective image in a screen pattern located on the light emitting face, whereby when the luminous display is emitting light, the luminous image dominates, and when the luminous display is not emitting light the reflective image dominates.

Claims

1. An image display device, comprising:

a) a luminous display having a light emitting face for providing a luminous image; and

b) a reflective image in a screen pattern located on the light emitting face, whereby when the luminous display is emitting light, the luminous image dominates, and when the luminous display is not emitting light the reflective image dominates.

2. The image display device of claim 1, wherein the luminous display is a backlit transparency, and the reflective image is formed on the light emitting face of the transparency.

3. The image display device of claim 1, wherein the luminous display is an OLED display having non light emitting portions interspersed with light emitting elements and the screen pattern of the reflective image is located over these non light emitting portions.

4. The image display device claimed in claim 3, wherein the OLED display is a color display.

5. The image display device claimed in claim 3, wherein the OLED display includes a transparent substrate, the OLED display emitting light through the substrate.

6. The image display device claimed in claim 1, further comprising:

c) a memory containing a digital image;

d) display drive electronics connected to the display and the memory for driving the display to show the digital image; and

e) a power source connected to the display drive electronics.

7. The image display device claimed in claim 6, wherein the content of the luminance image is related to the content of the reflective image.

8. The image display device claimed in claim 6, wherein the power source is a battery.

9. The image display device claimed in claim 6, wherein the memory includes an audio clip associated with the digital image, and further including a speaker connected to the display electronics for playing the audio clip in concert with the display of the digital image.

10. The image display device claimed in claim 6, wherein the digital image is a motion image sequence.

11. The image display device claimed in claim 1, wherein the screen pattern comprises a layer of reflective metal covered by a layer of reflective white material, covered by a layer of colored material.

12. The image display device claimed in claim 1, wherein the luminous display is a backlit LCD.

13. A method of making an image display, comprising the steps of:

a) providing a luminous display having a light emitting face for providing a luminous image; and

b) forming a reflective image in a screen pattern located on the light emitting face, whereby when the luminous display is emitting light, the luminous image dominates, and when the luminous display is not emitting light the reflective image dominates.

14. The method of claim 13, wherein the luminous display is a backlit transparency, and the reflective image is formed on the light emitting face of the transparency.

15. The method of claim 13, wherein the luminous display is an OLED display having non light emitting portions interspersed with light emitting elements, and the screen pattern of the reflective image is formed over these non light emitting portions.

16. The method of claim 15, wherein the OLED display is a color display.

17. The method of claim 15, wherein the OLED display includes a transparent substrate, the OLED display emitting light through the substrate.

18. The method of claim 13, further comprising the steps of:

c) providing a memory containing a digital image;

d) providing a display drive electronics connected to the display and the memory for driving the display to show the digital image; and

e) providing a power source connecting the display drive electronics.

19. The method of claim 18, wherein the content of the luminance image is related to the content of the reflective image.

20. The method of claim 18, wherein the power source is a battery.

21. The method of claim 18, wherein the memory includes an audio clip associated with the digital image, and further comprising the step of including a speaker connected to the display electronics for playing the audio clip in concert with the display of the digital image.

22. The method of claim 18, wherein the digital image is a motion image sequence.

23. The method of claim 13, wherein the luminous display is a backlit LCD.
