the first and second portions form an ‘L’ shape.

3. The thermal plate of claim 1 wherein:

the first portion of the thermal plate is in conductive thermal communication with a backlight assembly of the electronic display.

4. The thermal plate of claim 1 further comprising:

a plurality of apertures within the first portion which permit air to flow through the thermal plate.

5. The thermal plate of claim 4 wherein:

the apertures are slots.

6. The thermal plate of claim 5 wherein:

the slots are oriented parallel to the path of the air.

7. The thermal plate of claim 1 wherein:

the first and second portions are comprised of metal.

8. The thermal plate of claim 1 wherein:

the plate is positioned along an edge of the electronic display.

9. The thermal plate of claim 1 wherein:

the first portion of the thermal plate is in conductive thermal communication with an edge-lit LED backlight assembly of the electronic display.

10. A method for using a thermal plate to cool an electronic display within a thermally-conductive housing and having a transparent plate assembly positioned in front of the electronic display, the method comprising:

presenting a thermal plate comprising a first portion which is in conductive thermal communication with the electronic display, and a second portion extending from the first portion and placed within conductive thermal communication with the housing;

allowing heat to transfer from the electronic display to the first portion;

allowing heat to transfer from the first portion to the second portion; and

allowing heat to transfer from the second portion to the housing.

11. The thermal plate cooling method of claim 10 further comprising the steps of:

presenting a plurality of apertures within the thermal plate; and

forcing air through the apertures.

12. The thermal plate cooling method of claim 10 further comprising the steps of:

presenting a fan which draws air across the thermal plate and between the electronic display and the transparent plate assembly.

13. The thermal plate cooling method of claim 10 further comprising the steps of:

forcing air across the thermal plate and between the electronic display and the transparent plate assembly.

14. The thermal plate cooling method of claim 10 further comprising the steps of:

presenting a plurality of apertures within the thermal plate; and

forcing air through the apertures and between the electronic display and the transparent plate assembly.

15. A thermal plate assembly for use with first and second electronic displays placed back-to-back and within a thermally-conductive housing, each electronic display having an edge-lit backlight and a gap defined by the space between the electronic display and a transparent plate assembly, the thermal plate assembly comprising:

a first thermal plate placed in conductive thermal communication with the edge-lit backlight of the first display;

a second thermal plate placed in conductive thermal communication with the edge-lit backlight of the second display; and

a fan positioned to circulate air across the first and second thermal plates as well as through the gap for the first display and the gap for the second display.

16. The thermal plate assembly of claim 15 further comprising:

a plurality of apertures within the first and second thermal plates.

17. The thermal plate assembly of claim 16 wherein:

the fan is further position to draw air through the apertures of the first and second thermal plates.

18. The thermal plate assembly of claim 15 wherein:

the first thermal plate is further placed in conductive thermal communication with the housing; and

the second thermal plate is further placed in conductive thermal communication with the housing.

19. The thermal plate assembly of claim 15 further comprising:

a separating plate within the housing which divides the housing into lower and upper portions,

wherein the fan is positioned on the separating plate.
