Displays for self-service terminals

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;
• 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.

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;
• 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 self-service terminal 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.
