The display systems may include a display panel, a first transparent material and a second transparent material. The second transparent material may be located in between the first transparent material and the display panel. The first transparent material may have a first thermal conductivity and the second transparent material may have a second thermal conductivity. The second thermal conductivity may be greater than the first thermal conductivity. ## Claims ### Claim 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; wherein the second transparent material has a thermal conductivity of about 34 to 40 W/m·K; wherein the first transparent material is exposed to weather and is an outermost transparent layer of the display system; and wherein the display system is configured for operation in an exterior environment where visible and near-infrared solar radiation passes through the first transparent material and is absorbed by the display panel, and the second transparent material conducts thermal energy away from the display panel by thermal conduction to prevent a display panel temperature from rising beyond a specified working range that would result in display clearing. ### Claim 2 (depends on 1) The display system of claim 1, wherein the second transparent material is impregnated with crystallized aluminum oxide. ### Claim 3 (depends on 1) The display system of claim 1, wherein the second transparent material is sapphire. ### Claim 4 (depends on 1) The display system of claim 1, further comprising a thermal paste in contact with both the first transparent material and the second transparent material. ### Claim 5 (depends on 1) The display system of claim 1, further comprising a heat sink attached to the second transparent material. ### Claim 6 (depends on 5) The display system of claim 5, further comprising a thermal paste in contact with both the heat sink and the display panel. ### Claim 7 (depends on 1) 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. ### Claim 8 (depends on 1) The display system of claim 1, wherein there is not any voids between the display panel and the first transparent material and the second transparent material. ### Claim 9 A display system for a self-service terminal, the display system comprising: a display panel having a display surface;
