Case Study: High Luminance, Widescreen High-Resolution Display for Severe Dynamic Environment


This Military Weapon System Integrator requested a rugged avionics display that could provide a direct full-high definition (Full-HD) image of their modern high resolution sensors and cameras. In addition, this rotary-wing application required extreme flexibility in the operator control inputs for commanding the modes and positioning of the multiple weapon system devices and helicopter payloads.


The major challenge was the requirement to present high-resolution sensor, map, and symbology legibly in the wide range of ambient light conditions found in the cockpit of a military helicopter; from direct sunlight to dark night NVIS goggle operation. The customer’s weapon system is designed to accommodate a wide range of weapon payloads and mission configurations. The system achieves improved mission effectiveness by enabling the operator to efficiently control and monitor the system through a full suite of bezel controls, including: programmable bezel pushbuttons, dual concentric encoders, an 8-way joystick and a Night/Day/Off selector switch.


IEE created custom optical bonding with a heavy-duty, full color, very high bright (1,100 cd/m2 typical) high resolution screen (1920x1200) AMLCD. This 10.1-inch Multi-Function Display has very wide viewing angles and a selectable dual-mode LED backlight providing the flexibility needed to assist the operator. A heating unit was added for cold temperature operation. State of the art digital video capability requirements were satisfied with 2 x HD-SDI (with loop-through), 2 x DVI-D and a Serial Communication Interface (RS-422). The interface included an 8-way joystick, encoder knobs and thirteen programmable bezel pushbuttons to support a wide range of applications. IEE delivered the System Integration Lab, (SIL) units before moving to full production.

This 10.1" Multi-Function Display has been awarded the Editor’s Choice Award from Military Embedded Systems Magazine.
