Abstract

A lighting control method and an electronic device. The lighting of the display of the device can be adjusted according to ambient lighting. Information on the ambient lighting is transmitted to a light-sensitive component of the device through a light guide that is integrated as part of a protective display window.

Claims (30)

1. A method for controlling the lighting of a display in an electronic device, in which method

ambient light is led to a light-sensitive component of the device through a light guide,

the light-sensitive component controlling a display illuminator that lights the display on the basis of the ambient light,

wherein the light guide is integrated as part of a protective display window and configured to communicate light in a manner differing from that of other portions of the protective display window.

2. A method as claimed in claim 1 , wherein the protective display window and the light guide are manufactured as one shaped piece.

3. A method as claimed in claim 1 , wherein a display element is a liquid crystal element.

4. A method as claimed in claim 1 , wherein the display illuminator is arranged as a background light.

5. A method as claimed in claim 1 , wherein the electronic device is a mobile station.

6. A method as claimed in claim 1 , wherein the light guide comprises a second end defined relative to an inward-facing side of the protective display window, the second end extending a distance from the inward-facing side of the protective display window.

7. An electronic device comprising:

a display element,

a protective display window arranged to protect the display element,

at least one display illuminator,

a light-sensitive component that is arranged to control the illuminance of the illuminator on the basis of the ambient light,

a light guide that transmits the ambient light from the surroundings of the device to said light-sensitive component,

wherein the light guide is integrated as part of the protective display window and configured to communicate light in a manner differing from that of other portions of the protective display window.

8. An electronic device as claimed in claim 7 , wherein the protective display window and the light guide are manufactured as one shaped piece.

9. An electronic device as claimed in claim 7 , wherein the display element is a liquid crystal element.

10. An electronic device as claimed in claim 7 , wherein the display illuminator is arranged as a background light.

11. An electronic device as claimed in claim 7 , wherein the electronic device is a mobile station.

12. An electronic device as claimed in claim 7 , wherein the light guide comprises a second end defined relative to an inward-facing side of the protective display window, the second end extending a distance from the inward-facing side of the protective display window.

13. A display module comprising:

a display element,

a protective display window arranged to protect the display element,

at least one display illuminator,

a light-sensitive component that is arranged to control the illuminance of the illuminator on the basis of the ambient light,

a light guide that transmits the ambient light from the surroundings of the device to said light-sensitive component,

wherein the light guide is integrated as part of the protective display window, and wherein the light guide is shaped to transmit ambient light to the light-sensitive component in a manner differing from the other parts of the protective display window.

14. A display module as claimed in claim 13 , wherein the protective display window and the light guide are manufactured as one shaped piece.

15. A display module as claimed in claim 13 , wherein the light guide comprises a second end defined relative to an inward-facing side of the protective display window, the second end extending a distance from the inward-facing side of the protective display window.
