"The total number of touch-screen technologies including those in production and emerging products has increased from 16 distinct approaches in mid 2007 to 20 different touch-screen technologies this month," said Jennifer Colegrove, senior analyst for emerging displays at iSuppli. "New touch-screen technologies are being commercialized and 12 types of touch-screen technologies now have commenced mass production."

Catalyzed by Apple's highly successful iPhone, sales of touch screens using projected capacitive technology are growing dramatically. Projected capacitive touch-screen technology is more durable and has better transmittance than the more commonly-used resistive technology. More touch-screen manufacturers are developing and commercializing this type of screen. Furthermore, the average pricing gap between the capacitive and resistive display types is dwindling, making the technology more attractive.

3 h1 `* y7 H8 l/ g CResistive is the most commonly used touch-screen technology in the marketplace, accounting for 91% of global units in 2007. However, due to low average selling prices (ASPs) for this technology, it accounted for only 52% of total touch-screen market revenues.

However, the resistive market now is suffering a shortage of indium tin oxide (ITO) film used to make such screens due to production expansions among several major manufacturers and limited numbers of ITO film suppliers.

With several large manufacturers expanding capacity, other types of transparent conductive materials such as conductive polymer, carbon nanotube and antimony tin oxide (ATO) have an entry-to-market opportunity now. In fact, Fujitsu already has started using conductive polymer for some of its resistive-type touch screens.
