Fuel dispenser
A system and method for displaying information at a fuel dispenser comprises an electrophoretic display that may be configured to operate in low temperature environments. The fuel dispenser may comprise a keypad located beneath the electrophoretic display in order to present a graphical user interface to a customer and receive the customer's selections. The fuel dispenser may comprise additional electrophoretic displays to present additional information to the consumer.
1. A display system for a fuel dispenser comprising:
a printed circuit board comprising a metallization element configured to convey heat energy;
a heat generating device in thermal communication with the metallization element;
an electrophoretic display device in thermal communication with the metallization element, said electrophoretic display device having an active display portion; and
said printed circuit board and said electrophoretic display device being electrically interconnected such that operational signals may be supplied to said electrophoretic display device by means of said printed circuit board,
wherein the heat generating device generates localized heat that is dispersed throughout the metallization element, the metallization element largely corresponding with, and located proximate to, the active display portion of said electrophoretic display.
2. The display system of claim 1 wherein the metallization element of the printed circuit board comprises a plurality of metallization elements.
3. The display system of claim 2 wherein the metallization elements comprise a plurality of vias.
4. The display system of claim 1 further comprising a component configured to measure heat energy in thermal communication with the metallization element.
5. The display system of claim 1 further comprising an adhesive bonded to the electrophoretic display device.
6. The display system of claim 1 further comprising a thermal isolation barrier configured to cover at least a portion of the metallization element.
7. The display system of claim 1 further comprising an optically transparent thermal insulation barrier connected to the electrophoretic display device.
8. The display system of claim 1 further comprising an anisotropic membrane configured to provide the thermal connection between the electrophoretic display device and the metallization element.
9. The display system of claim 8 further comprising a physical retaining device configured to apply force to the electrophoretic display in order to compress the anisotropic membrane.
10. The display system of claim 1 wherein the printed circuit board comprises an electrical interconnection pad, the electrophoretic display device comprises an electrical mating pad, and the electrical interconnection pad corresponds with the electrical mating pad.
