Research Institution
The RGB LED High Performance and High Reliability LCD Backlight effort proposes to develop a modular, high efficiency full color spectrum RGB LED backlight capability for cockpit sized active matrix liquid crystal displays (AMLCD's). The design approach will develop a modular RGB LED backlight assembly that is capable of integrating with cockpit instrument displays. The proposed design will incorporate a closed loop backlight color control system with a communication link between the backlight engine and the instrument graphics controller. It will include a spectral RGB photodiode sensor to provide feedback to maintain desired spectral output of the backlight to compensate for aging, binning effects in the LED's, display head interchangeability, and color correlation information on the displayed graphics for optimized contrast. The spectral RGB sensor will be standardized against the CEI color spectrum for inter-operability. The spectral sensor and backlight system will be developed to provide NVIS compatibility. The proposed effort will extrapolate from existing C3I work in RGB LED spectral color control and backlighting developments. The proposed effort will include exploration of new fabrication techniques that improve on heat management, reliability, and ability to meet severe environmental performance requirements of shock, vibration, EMI, thermal stress and other performance related issues that may be identified.
