Avago Technologies announced that it has developed a new touch screen interface that greatly enhances the operation and navigation of Smart Phones, portable media players, and a wide range of other portable electronic communications devices. This new touch screen technology from Avago is a mutual capacitance, multi-touch controller that is capable of tracking up to four simultaneous touch points without the problem of ghost points.
A touch screen system typically consists of an LCD or organic light-emitting diode (OLED) display, a touch sensitive panel, a protective cover lens, and a touch screen controller. Other key features of Avago’s touch screen interface include 500 dpi resolution for jitter free smooth tracking; hover rejection and palm detection to prevent false touch responses; good adjacent touch resolution for finer screen features and sensitivity; and 13-inch per second tracking speed to provide screen navigation that is fast, responsive and suitable for gaming applications.
“Today’s announcement of our new touch screen panel is yet another example of technology leadership in this market, and helps to reaffirm our position as a major supplier of navigation interfaces to all the major Smart Phone and mobile communications handset manufacturers,” said Khin-Mien Chong, vice president and general manager, Navigation Interface Division, Avago Technologies. “Our touch screen interface controller is designed to enhance the overall touch screen experience.”
Avago’s new capacitive touch panel controller is currently shipping to an unnamed portable media player manufacturers and several key mobile handset manufacturers are currently sampling Avago’s touch screen controller for use in their next generation designs.
