Abstract

A display module which is to be mounted on a printed circuit board of an electronic device includes a display element. The display module further includes at least two thin layers of a transparent material, such as glass or other similar material. The display element and the at least two thin layers of rigid transparent material are part of a laminated structure where the different layers of the laminated structure are attached together with an adhesive. In this way a stronger and more robust display module is provided. This allows the thickness of the housing of the electronic device to be reduced since there is no need for a protective glass plate and an air gap in front of the display module.

Claims

1. A display module for an electronic device, the display module comprising:

a display element, and

at least two thin layers of rigid transparent material;

wherein the display element and the at least two thin layers of rigid transparent material are part of a laminated structure in which different layers of the laminated structure are attached together with an adhesive.

2. A display module according to claim 1, wherein the at least two thin layers of rigid transparent material are separated by an adhesive and are arranged at a front of the display element.

3. A display module according to claim 1, wherein the at least one thin layer of rigid transparent material is arranged at a rear of the display element.

4. A display module according to claim 1, wherein the display module further comprises at least one polarizer arranged at a front of the display element and at least one polarizer arranged at a rear of the display element.

5. A display module according to claim 4, wherein the polarizer arranged at the front of the display element comprises an outermost layer of the display module.

6. A display module according to claim 1, wherein an outermost layer of the display module comprises a scratch resistant layer.

7. A display module according to claim 1, wherein the display module further comprises a lighting element arranged at a rear of the display element.

8. A mobile electronic device comprising a display module according to claim 1.

9. A mobile electronic device according to claim 8 wherein the mobile electronic device comprises a mobile telephone.

10. A printed circuit board on which is mounted a display module according to claim 1.

11. A display module according to claim 1, wherein the at least two layers of rigid transparent material comprise a first layer of a first rigid transparent material and a second layer of a second rigid transparent material, wherein the second rigid transparent material is different from the first rigid transparent material.

12. A display module according to claim 1, wherein the rigid transparent material comprises glass.
