1. An apparatus for thermally managing a display case comprising:
- a housing adapted to hold a plurality of products, wherein said housing defines an opening; and
an access panel assembly mounted to the housing and configured to move between an opened position, whereby the products may be accessed, and a closed position, whereby the access panel covers the opening, wherein said access panel assembly comprises;
a transparent electronic display having a perimeter and configured to display an image and permit the products to be simultaneously viewed therethrough;
a light guide positioned behind the transparent electronic display;
a number of illumination devices positioned adjacent to one or more edges of the light guide such that light emitted from the illumination devices is configured to travel through said light guide and illuminate the transparent electronic display; and
a thermal plate positioned adjacent to and in thermal communication with the illumination devices, wherein said thermal plate is configured to absorb heat produced by the illumination devices, wherein said thermal plate extends beyond the perimeter of said transparent electronic display and is configured to release said absorbed heat to the ambient environment, and wherein the entirety of said thermal plate is located beyond the perimeter of said transparent electronic display such that no portion of the image displayed on said transparent electronic display is obscured.

Abstract
An apparatus for viewing an image and a plurality of products simultaneously includes a display case to holds the products. An access panel assembly is placed over an opening in the case to allow access to the products. The assembly includes a transparent electronic display for displaying the image which is located in front of a light guide. A number of illumination devices are placed adjacent to an edge of the light guide to help illuminate the display. A thermal plate is located in close proximity to the illumination devices to conduct heat produced therefrom.

12. An apparatus for thermally managing a display case comprising:
-
a housing adapted to hold a plurality of products within a refrigerated cavity; and an access panel assembly located on said housing and configured to permit access to said products, wherein said access panel assembly comprises; a first transparent layer; a second transparent layer positioned adjacent to said refrigerated cavity; a transparent electronic display located between said first and second transparent layer and having a perimeter; a light guide positioned between said transparent electronic display and said second transparent layer; a number of lights positioned adjacent to at least one edge of said perimeter of said light guide such that the light from said number of lights is configured to pass through the light guide and illuminate the transparent electronic display and the plurality of products in a way which permits the image and the plurality of products to be viewed simultaneously; and a heat sink attached to said second transparent layer and extending adjacent to the number of lights, wherein said heat sink is in conductive thermal communication with the number of lights and is configured to absorb heat generated by said number of lights, wherein the entirety of said heat sink is located beyond the perimeter of said transparent electronic display such that no portion of the transparent electronic display is obscured by said heat sink. - View Dependent Claims (13, 14, 15, 16)
