2. Agenda • Touch Sensors and the Market Trend • Manufacturing of Projective-Capacitive Touch Modules • Introduction of UniDisplay --- A projective-capacitive touch sensor maker

3. Merits of multi-touch applications Multi-touch • Intuition inducing • Smooth interaction • Dynamic interaction • Friendly interaction • …etc. • Much more new applications to be created in the near future. • The new applications will inevitably spread into most human interface intensively used applications. iPhone

4. Comparisons of touch panel technologies • Although IR method can also offer the multi-touch capability, projective-capacitive touch panel technology is the most suitable for portable devices.

7. The market share by touch methods Source: Touch Screen Report 2008, DisplaySearch • The estimated growth rates ofsurface- and projective-capacitivetouchis about 4 and 280%, respectively, from 2007 to 2008. • It implies that projective-capacitivetouch will contribute the major part of the growth. 7
