Environmental

DLP systems have passed a series of environmental and regulatory tests to simulate thermal shock, temperature cycling, mechanical shock, vibration, moisture resistance, and acceleration conditions.

The TI DMD™ and the Environment
Most reliability concerns are focused on the hinges that tilt the mirrors from one position to another. To test reliability, DMDs were subjected to accelerated life cycle tests simulating approximately 20 years of use. Inspection of the devices after the testing showed no broken hinges on any of the devices. Texas Instruments has completed thousands of hours of life cycle and environmental testing to conclude that the DMD and DLP systems are inherently reliable. Combat Displays display system has passed the military environmental tests with no adverse affects to the DMD and supporting DLP chip set.

 
Environmental Testing
Combat Displays systems meet the most demanding cockpit and environmental requirements, performing reliably in adverse conditions while displaying vital information to the user that can make the difference between mission success and failure. Combat Displays system has been tested to and passed the following:

  Thermal Analysis, IAW MIL-STD –810, Methods 501 and 502
  Humidity, IAW MIL-STD-810F, Method 507.4
  Vibration, MIL-STD-167-1
  Shock, MIL-S-901D
  Radiated Emissions, MIL-STD-461E, Requirement RE102
  Conducted Emissions, MIL-STD-461E, Requirement CE102

Depending upon the requirements, Combat Displays’ systems testing may include the following:

Lighting  
MIL_STD-3009 LIGHTING, AIRCRAFT, INTERIOR, NIGHT VISION IMAGING SYSTEM (NVIS) COMPATIBLE
MIL-L-85762A LIGHTING, AIRCRAFT, INTERIOR, NIGHT VISION IMAGING SYSTEM (NVIS) COMPATIBLE
