Abstract
A display case door for a product storage device includes a transparent unit through which products within the product storage device are visible. The transparent unit includes a transparent LCD panel configured to present visual media content. The display case door further includes an electrical hinge pin rotatably coupling the display case door to the product storage device and one or more electrical conductors extending through the electrical hinge pin. The electrical conductors deliver the visual media content to the transparent LCD panel from a remote data source.
