Non-ruggedized COTS display packaging for severe environment applications
View Patent ↗A modular display assembly comprising a light emitting or transmitting display panel and a glass panel wherein: the display and glass panel are separated from each other by a frame assembly; and the display is coupled to the frame assembly by at least one elastic isolator.
1. A modular display assembly for enclosing a light emitting or transmitting display subassembly, comprising:
a solid base plate formed out of an electrically and thermally conductive material;
a frame formed out of a material providing impact resistance and thermal and electrical conductivity fixedly attached to the base plate around the periphery, forming a cavity, the frame having an opening;
a glass panel fixedly attached to the frame at the opening for enclosing the cavity; and
an elastic isolator having thermal conductivity fastening the display subassembly to the solid base plate.
2. The assembly of claim 1 wherein the elastic isolator has a thermal conductivity, thickness, and cross-sectional area in contact with the frame and base plate, sufficient to conduct heat generated by the display subassembly to the base plate so that the display stays within operational temperature limits.
3. The assembly of claim 2 wherein the display subassembly is a commercial off the shelf flat display.
4. The assembly of claim 3 wherein the glass panel and frame are attached via mating beveled edges, flexible bonding material, angle clamps, or captivating grooves.
5. The display assembly of claim 4 wherein the plate, frame and glass panel are all electrically conductive and form a Faraday cage around the display subassembly.
6. The assembly of claim 5 wherein the display subassembly is positioned relative to the glass panel in the frame.
7. The display assembly of claim 5 wherein the display subassembly is fastened to frame via the at least one plastic isolator.
8. The display assembly of claim 5 wherein one or more circuit boards comprising control circuits for the display assembly are coupled to the base plate on a side opposite the side to which the display subassembly is attached.
9. The display assembly of claim 2 wherein the display subassembly is able to withstand continuous operating and storage temperatures from −55 C to 100 C per MIL-STD-810 and sustained 3-axis shock and vibration up to 40 g's per MIL-STD-810.
