Abstract
A display for an ice rink, comprising a first layer of ice within a peripheral boundary of the ice rink. An array of hermetically sealed, multiple individual organic light emitting diodes are positioned within the peripheral boundary on top of the first layer of ice. A second layer of ice on top of the array has an internal side facing the array and an external surface on a side opposite the internal side. A power source operatively connected to the array provides power to the individual organic light emitting diodes in the array. The multiple individual organic light emitting diodes are selectively controllable such that graphic images can be displayed by using specific organic light emitting diodes selected from among the individual organic light emitting diodes in the array and the graphic images will be visible through the external surface of the second layer of ice.
