Touch panel is attached in the liquid crystal display device, the use of a finger or stylus pressure display panel, for intuitive human-computer interface, application scope covers mobile phones, ebook, computer dictionary, DSC, GPS, ATM, etc. Touch technology in accordance with the panel size distinguish, its main technology for: 12 inches or more, to surface acoustic wave, surface type capacitance, optical type etc give priority to; 12 inches below to projection

Projection capacitive touch technology will be the mainstream of mobile phone market. Touch panel demand rapid growth, it has touch industry market growing size, yuan for the points out, among them, the projection capacitance will into the mobile phone market mainstream, the existing related leading manufacturers of capacity expansion, profitability ascension are good long-term trend.

Touch panel is attached in the liquid crystal display device, the use of a finger or stylus pressure display panel, for intuitive human-computer interface, application scope covers mobile phones, ebook, computer dictionary, DSC, GPS, ATM, etc. Touch technology in accordance with the panel size distinguish, its main technology for: 12 inches or more, to surface acoustic wave, surface type capacitance, optical type etc give priority to; 12 inches below to projection capacitance (film, glass), resistance type primarily.

For the participants in the near future to "touch industry - projection capacitance demand to soar" issued under the industry research report. Pointed out that Apple use projection glass capacitance bring smooth touch, estimated today, next year sales iPhone respectively for 40 million a, 50 million a, IPad for 12.9 million sets, 36.5 million, and will drive each manufacturers improve projection capacitance specific gravity, estimate 2010 projection capacitance in mobile phone permeability, 38% in 2011, up to 60%; Tablet PC (10.1 inches below) have more than 90% will use projection capacitance. For the participants with 500 million branch touch cell phone (capacitance mobile phone 190 million cigarettes) and 50 million sets of tablet PC as the main growth kinetic energy, estimate 2011 projection capacitance output will reach to 8.7 billion usd, increasing 43%.

Projection capacitance main technology is divided into film type, glass type. Glass type capacitance is optical properties is excellent, but film type capacitance low cost 15% ~ 50%, thickness also has relatively thin, different brand manufacturers based on the product difference consideration and have different preference for participants to think, 2011 glass and film capacitance value will be a reversal was 136% and 331%, respectively (including Apple mobile phone + iPad accounted for the proportion of glass type capacitance value as high as 70%).

Glass type capacitance tactile sensor process and color filter process similar, namely have sputtering, spraying, etching, cutting processes, in touch promising industry needs, predictable, color filter manufacturers will also shift to touch panel module manufacturers. But for participants to think, the original namely have 3.5 generation plant the following CF manufacturers, turn do touch module is potentially competitive, and touch module factory profit focuses on joint yield, new entrants needs 1 ~ 1.5 years of learning curve, expected the second half of 2011 years to 2012 years industry competition will aggravate, before this, glass type capacitance huge demand, will only benefit first by the original Apple supply chain.

As for the film type capacitance, its equipment and resistance type equipment part of the Shared, so, film type capacitance needs beneficiary will be the original resistance supply chain is given priority to, such as the China, interface and so on, competitors are Japanese, Korean manufacturers.
