San Juan


  • 8.4” SVGA sunlight readable display
  • Wireless Video Input
  • Light weight display.
  • Remote CPU

The San Juan is a “proof of concept” EFB system that demonstrated the utility of 8.4” SVGA sunlight readable displays in a cockpit environment. The display head measured 6.0” x 8.5” x 1.125“ and weighed 2.1Lbs. It included the AMLCD display, a high dimming ratio backlight, touch screen, keyboard interface and controller. The display utilized an LVDS interface to minimize EMI. The remote mounted 400MHz Pentium based CPU measured 4.8” x 6.0” x 1.8 and weighed 3.1 Lbs.

About This Project:

The San Juan project objective was to create an EFB prototype system for cockpit evaluation. The client, Boeing Cabin Information Services, needed to present an EFB option in 8 weeks. We were able to meet Boeing’s tight schedule and deliver a complete “road show” demonstration system.
