SEOUL, Korea (AVING) — <Visual News> Samsung Electronics showcased a single chip that integrates a capacitive touch screen control function in a mobile display driver IC(DDI), based on Samsung’s Touch Embedded DDI technology at the sixth annual Samsung Mobile Solutions Forum held at the Westin Taipei Hotel.
This single chip Touch Embedded DDI solution supports industry demand for simplified system designs, which will enable the use of slimmer form factors in mobile application designs. Initial targeted applications for the Touch Embedded DDI include mobile phones, portable multimedia players (PMP) and MP3 players.
Compared to resistive touch screen control technology, capacitive touch screen control technology allows more advanced features such as soft-touch and multi-touch functions and provides significant improvement in important performance parameters such as optical transmittance and durability.
According to Display Search, Inc., the global mobile handset market, which is the primary application for mobile display driver ICs, is expected to reach 1.2 billion units this year and grow to 2 billion units by 2012. Sales of touch-screen phones are forecasted to increase at a compound annual growth rate of 30 percent to account for 27 percent of total handsets sold in 2012.
