In some embodiments of the present invention, a vending machine display apparatus and method includes a controller, an electroluminescent display electrically coupled to the controller and adapted to be coupled to the vending machine in a location externally visible on the vending machine, and a power line coupled to the electroluminescent display and adapted to supply power to the electroluminescent display. The electroluminescent display can be associated with the user-manipulatable control and/or with a product in the vending machine dispensed by operation of the user-manipulatable control. In some embodiments, the electroluminescent display is responsive to the controller by changing graphics and/or text displayed by the display.
