Avago Technologies has developed an innovative 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 that are found in most other competing capacitive sensing technologies.
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.
