Abstract
The present invention is a robust LED display module for use in an electronic sign which display module includes a metallic housing, a heat conductive interface panel, an LED circuit board and LEDs, and a metallic mask arranged in intimate contact and association therewith, and which components operate synergistically in concert with each other in order to evenly distribute, reduce and dissipate heat along, about and within the structure of the present invention. Display uniformity is provided by the use of major metallic structures in order to prevent warpage and to protect the geometric integrity of the LED display module.
