GCC-1

GEMexpressTM is a universal TFT/OLED driver PCBA GEMexpress TM GCC-1 Data Sheet Introduction: It is a fast, inexpensive production solution for adding a graphic user interface to an embedded product. GEMexpressTM allows for greater design flexibility and a shorter time to market. This new hardware approach to GUI integration contains all of Amulet’s bill of materials, which is everything needed to drive the user interface. It just needs to be attached to a simple display interface board and the human interface is ready for production. As it’s easy to integrate, Amulet sees it as the “express” lane to production: fast, easy and cost effective.
