DISPLAYS FOR SELF-SERVICE TERMINALS

1 . A display system for a self-service terminal, the display system comprising:

a display panel;

a first transparent material having a first thermal conductivity; and

a second transparent material located in between the first transparent material and the display panel, the second transparent material having a second thermal conductivity, the second thermal conductivity being greater than the first thermal conductivity.

2 . The display system of claim 1 , wherein the second transparent material is impregnated with crystallized aluminum oxide.

3 . The display system of claim 1 , wherein the second transparent material is sapphire.

4 . The display system of claim 1 , further comprising a thermal paste in contact with both the first transparent material and the second transparent material.

5 . The display system of claim 1 , further comprising a heat sink attached to the second transparent material.

6 . The display system of claim 5 , further comprising a thermal paste in contact with both the heat sink and the display panel.

7 . The display system of claim 1 , wherein the second thermal conductivity is greater than the first thermal conductivity by at least 1 order of magnitude.

8 . The display system of claim 1 , wherein there is not any voids between the display panel and the first and second transparent materials.

9 . A display system for a self-service terminal, the display system comprising:

a display panel having a display surface;

a first transparent material having a first surface and a first thermal conductivity; and

a second transparent material having a first surface in contact with the first surface of the first transparent material and a second surface in contact with the display surface, the second transparent material having a second thermal conductivity, the second thermal conductivity being substantially greater than the first thermal conductivity.

10 . The display system of claim 9 , wherein the second transparent material is impregnated with crystallized aluminum oxide.

11 . The display system of claim 9 , wherein the second transparent material is sapphire.

12 . The display system of claim 9 , further comprising a thermal paste located in between the first surface of the first transparent material and the first surface of the second transparent material.

13 . The display system of claim 9 , further comprising a heat sink attached to the second transparent material.

14 . The display system of claim 12 , further comprising a thermal paste in contact with both the heat sink and the display panel.

15 . The display system of claim 9 , wherein the second thermal conductivity is greater than the first thermal conductivity by at least 1 order of magnitude.

16 . The display system of claim 9 , wherein there is not any voids between the first surface of the first transparent material and the first surface of the second transparent material.

17 . A self-service terminal comprising:

a display panel;

a first transparent material having a first thermal conductivity;

a second transparent material comprising crystallized aluminum oxide, the second transparent material located in between the first transparent material and the display panel, the second transparent material having a second thermal conductivity, the second thermal conductivity being greater than the first thermal conductivity; and

a heat sink in contact with the second transparent material.

18 . The self-service terminal of claim 17 , wherein the second transparent material is a sapphire panel.

19 . The self-service terminal of claim 17 , wherein the second thermal conductivity is greater than the first thermal conductivity by at least 1 order of magnitude.
