Various touch modes are also a major feature of touch screens. In the past, the mainstream method of touch screens was the resistive type. In addition, touch screens of other methods were integrated in a small number of products with larger sizes (above l〇in). Even in 2008, the number of resistive touch screens reached about 70 percent , and the amount accounted for more than half. However, as a commodity project, it is a trend to require integrated touch screens in large-size products, and with the continuous emergence and commercialization of new technologies, it is difficult to predict the future of resistive touch screens. One of the main factors is that Apple has adopted projected capacitive touch screens in iPhones. Taking this as an opportunity, the proportion of projected capacitive touch screens used in mobile phones has changed significantly. The biggest feature of the projected capacitive touch screen is that it can realize "multi-touch" and can greatly improve the display ability of the LCD screen. How this touch method can be extended to products other than mobile phones, when will it be possible to achieve mass production of large-size products above 5in, and how to reduce costs, this has attracted attention.
However, the resistive touch screen, which is said to be unable to realize multi-touch, has completed more and more technological developments, so it should not be neglected. In addition, there are products that integrate a touch-sensitive panel and a liquid crystal display. The structure combines two methods. The capacitive touch screen realizes the proposal of a high transmittance method at low cost and other new technology development and new product launches. The development and changes in electronic display technology are also great, and future growth has become reliable.
The market size of the flat panel display market is huge, exceeding 10 trillion yen, and the number and display area will continue to expand in the future, but the price scale of flat panel displays will show slow growth or be in a downturn. This is the consensus view of the industry, but touch screens The market will develop rapidly in the future, which has become the consensus of the industry. Figure 6 shows the expected size of the market. In terms of touch screen shipments, it was 480 million in 2009, but it will grow to 1.4 billion in 2015. In terms of price, the market value in 2009 was US3.7 billion, but by 2015 it is expected to reach US9 billion.
