Abstract

A portable electronic device including a transparent display module, and a method of incorporating a transparent display module into a portable electronic device, are provided. The portable electronic device includes a front side surface which is intended to be primarily used facing toward a principal user and a back side surface, which is intended to be primarily used facing away from the principal user. The portable electronic device includes a transparent display module including a primary light emitting transparent display having a first side surface and a second side surface, which emits a light toward each of the first side surface and the second side surface in disproportionate amounts, where an amount of light emitted toward the first side surface is less than an amount of light emitted toward the second side surface. The transparent display module is mounted in the portable electronic device, so that the first side surface of the transparent display module which emits the lesser amount of light is oriented toward the front side surface of the portable electronic device, and the second side surface of the transparent display module which emits the greater amount of light is oriented toward the back side surface of the portable electronic device.

Claims

1. A portable electronic device having a front side surface, which is intended to be primarily used facing toward a principal user and a back side surface, which is intended to be primarily used facing away from the principal user, the portable electronic device comprising:

a transparent display module including a primary light emitting transparent display having a first side surface and a second side surface, which emits a light toward each of the first side surface and the second side surface in disproportionate amounts, where an amount of light emitted toward the first side surface is less than an amount of light emitted toward the second side surface, and

wherein the transparent display module is mounted in the portable electronic device, so that the first side surface of the transparent display module which emits the lesser amount of light is oriented toward the front side surface of the portable electronic device, and the second side surface of the transparent display module which emits the greater amount of light is oriented toward the back side surface of the portable electronic device.

2. A portable electronic device in accordance with claim 1, wherein elements located behind the device can be seen in conjunction with and through an image produced by the primary light emitting transparent display.

3. A portable electronic device in accordance with claim 1, wherein the transparent display module further includes a touch sensor located on at least one of the first side surface of the primary light emitting transparent display or the second side surface of the primary light emitting transparent display.

4. A portable electronic device in accordance with claim 3, wherein the touch sensor includes a capacitive touch sensor adapted for detecting a location of a pointer element coming within proximity of the corresponding touch sensor.

5. A portable electronic device in accordance with claim 3, wherein the touch sensor includes a resistive touch sensor adapted for detecting a location and an amount of force of a pointer element coming into contact with the corresponding touch sensor

6. A portable electronic device in accordance with claim 1, wherein the display module further includes a secondary light emitting transparent display, which at least partially overlaps with the primary light emitting transparent display in a direction perpendicular to an image plane of each of the primary light emitting transparent display and the secondary light emitting display, the secondary light emitting transparent display having a first side surface and a second side surface, which emits a light toward each of the first side surface and the second side surface in disproportionate amounts, where an amount of light emitted by the secondary light emitting transparent display toward the first side surface is less than an amount of light emitted toward the second side surface, where the first side surface of the secondary light emitting transparent display is oriented in the same direction of the first side surface of the primary light emitting transparent display.

7. A portable electronic device in accordance with claim 6, wherein the image plane of the primary light emitting transparent display is substantially parallel to the image plane of the secondary light emitting transparent display.

8. A portable electronic device in accordance with claim 6, wherein an image produced by the primary light emitting transparent display and an image produced by the secondary light emitting transparent display are simultaneously perceivable by the user viewing the device from the front side surface.

9. A portable electronic device in accordance with claim 6, wherein the transparent display module further includes a first touch sensor located on the first side surface of the primary light emitting transparent display, and a second touch sensor located on the second side surface of the secondary light emitting transparent display.

10. A portable electronic device in accordance with claim 1, wherein the primary light emitting transparent display includes an emissive layer between an array of addressable anodes and an array of addressable cathodes.

11. A portable electronic device in accordance with claim 10, wherein the array of addressable cathodes are located on the first side surface of the emissive layer, and the array of addressable anodes are located on the second side surface of the emissive layer.

12. A portable electronic device in accordance with claim 11, wherein the cathode is formed from a metal having a thickness that is sufficiently thin to provide at least partial transmissivity, while maintaining sufficient conductive coverage.

13. A portable electronic device in accordance with claim 1, wherein the primary light emitting transparent display includes a transparent organic light emitting diode display.

14. A method for using one or more light emitting transparent displays in a portable electronic device comprising:

placing a primary light emitting transparent display into a portable electronic device, such that a first side surface of the primary light emitting transparent display is oriented toward a front side surface of the portable electronic device, which is intended to be primarily used facing toward a principal user, and such that a second side surface of the primary light emitting transparent display is oriented toward a back side of the portable electronic device, which is intended to be primarily used facing away from the principal user; and

emitting an image via the primary light emitting transparent display, so that a lesser amount of light associated with the image is emitted toward the first side surface of the primary light emitting transparent display, and a greater amount of light associated with the image is emitted toward the second side surface of the primary light emitting transparent display.

15. A method in accordance with claim 14, further comprising:

placing a secondary light emitting transparent display into a portable electronic device, which at least partially overlaps with the primary light emitting transparent display in a direction perpendicular to an image plane of each of the primary light emitting transparent display and the secondary light emitting display, such that a first side surface of the secondary light emitting transparent display is oriented toward a front side surface of the portable electronic device, which is intended to be primarily used facing toward a principal user, and such that a second side surface of the secondary light emitting transparent display is oriented toward a back side of the portable electronic device, which is intended to be primarily used facing away from the principal user; and

emitting an image via the secondary transparent light emitting display, so that a lesser amount of light associated with the image is emitted toward the first side surface of the secondary light emitting transparent display, and a greater amount of light associated with the image is emitted toward the second side surface of the secondary light emitting transparent display, where the first side surface of the secondary light emitting transparent display emits light in the same direction of the first side surface of the primary light emitting transparent display, and the second side surface of the secondary light emitting transparent display emits light in the same direction of the second side surface of the primary light emitting transparent display.
