LED Display for Use in High Impact Environments

A light emitting diode (LED) display unit for use in high impact environments, the LED display unit comprising:

• a frame disposed within a housing;
• and
• a plurality of display modules attached to the frame, each display module being substantially rectangular in shape and comprising:
• a support structure having a rear surface and a front surface;
• a foam shock absorber disposed between the frame and the rear surface of the support structure, wherein the foam shock absorber has a plurality of apertures;
• a plurality of spring-biased shock absorbers, each disposed within a corresponding one of the plurality of apertures in the foam shock absorber, wherein each of the spring-biased shock absorbers comprises a spring-biased piston portion within a sleeve portion, wherein at least four of spring-biased shock absorbers are disposed adjacent corresponding corners of the display module;
• a printed circuit board attached to the front surface of the support structure, the printed circuit board having an array of LEDs and a plurality of apertures disposed within the array of LEDs;
• and
• a front protective panel covering the array of LEDs, wherein the front protective panel includes a plurality of posts that extend from a rear surface of the front protective panel, wherein the plurality of posts are received within the plurality of apertures disposed within the array of LEDs,
• wherein the front surface of the support structure includes a plurality of sockets that receive the plurality of posts extending through the plurality of apertures in the printed circuit board, and
• wherein the foam shock absorber and the plurality of spring-biased shock absorbers in combination provide shock absorption that prevents damage to the printed circuit board when the front protective panel is impacted by a foreign object.
