Jennifer Colegrove, senior analyst for display technology and strategy at iSuppli Corp., said, "Demand for touchscreen displays is being driven primarily by the mobile-phone and consumer-electronics industriesspecifically portable game consoles, PDAs and portable navigation devices. However, as the market matures, iSuppli believes that touchscreen displays will find a role in nearly every aspect of electronics lifefrom planes to automobiles to machine-control systems to home appliances."

Resistive touchscreen segment

The eight leading technologies are resistive, surface capacitive, projected capacitive, infrared, SAW, optical, bending wave and active digitizer (Figure 2).

The resistive touchscreen market comprises more than two-thirds of the more than 100 varieties of touchscreen components. The advantages of resistive touchscreen displays include low price, high resolution, mouse tracking, small-target activation and the fact that they are not affected by dirt, dust, water or light.

Because of the wide competitive field, the resistive touchscreen market is currently in the midst of a price war, with ASPs expected to plummet 10 percent annually for the next five years, according to iSuppli.

Despite drawbacks, the resistive touchscreen market will still experience major growth in terms of unit shipments. However, revenue won't see much growth as other technologies eat into the resistive business. This market will still reach $1.67 billion by 2012, rising at a CAGR of 3.1 percent from $1.39 billion in 2006.

Emerging market

Multitouch is emerging as a popular option, thanks to Apple's iPhone and new designs such as Microsoft's concept tabletop computer.

iSuppli believes that the applications most suitable for multitouch screen displays are new handheld videogame systems, map-browsing systems and new mobile handsets that have a variety of additional applications beyond voice communications.

The market for multitouch touchscreens is set to grow to $433.1 million in 2012, rising at a CAGR of 30.8 percent from $112.9 million in 2007.
