Rigid-Flex PCB Case Study

Rigid-Flex PCB Design for an Innovative Helmet-Mounted Display

The US Air Force engaged HoloEye Systems to create a prototype binocular holographic waveguide visor display (HWVD) attached to the helmet worn by a pilot of an Air Force jet. Advanced sensors throughout the aircraft generated key info that the pilot needed. This helmet-mounted display (HMD) presented a heads-up display of instrumentation and digital representations of important data. The helmet was the heart of the aircraft, enabling the pilot to take advantage of the whole system.

This cutting-edge technology significantly decreased the cost, volume and weight of traditional helmet-mounted displays, replacing bulky optics systems with thin, light-weight, see-through diffractive optics. The headset display was one of the first reported binocular HMDs in development using a liquid crystal and silicon (LCOS) microdisplay.
