Title:  High Performance/Reliability Display Backlighting
Research & Technical Areas:  Electronics

Acquisition Program:  PMA-209 Air Combat Electronics. [Non-ACAT]
  Objective:  Enhance the performance/reliability of cockpit sized active matrix liquid crystal displays (AMLCDs) for aircraft, using an advanced modular light emitting diode (LED) backlight assembly.
  Description:  Current AMLCDs employ inefficient backlight technology, which introduces significant power, heat and reliability penalties that reduce mission effectiveness for airborne applications. Innovative LED illumination and control technologies, which synchronize the backlight with the displayed image, greatly enhance the optical performance of the AMCLD by providing extremely high-contrast ratios and enhanced image clarity.

  PHASE I: Provide a design concept and determine the feasibility of developing an LED backlight assembly to enhance performance/reliability of an AMCLD for airborne applications. Develop performance specifications based upon available data and preliminary concept designs.
  PHASE II: Develop a night vision (NVIS) compatible display head assembly prototype capable of being installed in an existing flight display. Perform optical and preliminary environmental tests (thermal, vibration and electromagnetic interference (EMI)) in a laboratory environment. Refine factors that affect performance and identify limitations.

  PHASE III: Incorporate the NVIS compatible display head assembly into ongoing Air Combat Electronics display programs. Perform full system development and demonstration (SD&D) of the technology for aircraft integration and production. PRIVATE SECTOR COMMERCIAL POTENTIAL/

  DUAL-USE APPLICATIONS: High-performance computer monitors, medical imaging systems, and high-definition televisions would all benefit from this technology.
