Electronic enthusiasts in October "hot touch technology special issue " hot download, how can you lack!
The promising touch screen market allows mainland manufacturers to plan a new pattern in the horse racing circle, either to expand production capacity, or to merge or acquire, or to invest in new plants, introduce new production lines, and spare no effort to seize market share. But there are also manufacturers who resell factories and close down when the momentum is growing. Two very different phenomena can't help but make people wonder, how long will the touch industry still flourish?
In recent years, driven by high-end electronic products from Apple and other manufacturers, the development of the touch screen industry has become more and more in-depth, and the expanded fields have become wider and wider. The accumulation of quantity has entered an explosive period of qualitative change. According to predictions by relevant market research institutions, global tablet PC sales will reach 248.6 million units by the end of 2015. In terms of smartphones, global smartphone sales are expected to reach 1.05 billion units by 2015, with sales in the Asian market accounting for 39.5%. The promising touch screen market allows mainland manufacturers to plan a new pattern in the horse racing circle, either to expand production capacity, or to merge or acquire, or to invest in new plants, introduce new production lines, and spare no effort to seize market share. But there are also manufacturers who resell factories and close down when the momentum is growing. Two very different phenomena can't help but make people wonder, how long will the touch industry still flourish?
1. Overview of the development of the domestic touch screen industry
Changes in a country ’s stock market reflect the current development of the country ’s economy. At present, the touch screen is one of the sectors that have attracted the most attention in the industry since the hot market of smart terminals. In the recent period, the touch screen concept stocks have continued to oscillate strongly. Sanan Optoelectronics and other companies have made great gains.
Due to the large capacity of the mainland China market and numerous consumer levels, many manufacturers have their own market segments. At present, manufacturers mainly based on resistive touch screen products such as Continental Fuyang Solar, Huayi Circuit, Beitai Display, Huangze Optoelectronics, Shenyue Optoelectronics, Watson Electronics, etc. are still working on touch screens and touch controls in the middle of the industry chain. Expand the field of panel manufacturing, and try to maintain its own market share. And mainstream touch screen manufacturers such as CSG, Leybold High-tech, Tianma A have conducted research and development of OGS touch screens to ensure their leading position in the touch screen market.
At present, there are mainly 24 types of applications for touch screens, and smartphones, tablets, and laptops are the main application fields. As the size of the touch screen market increases, the potential of the large-size touch screen market is unlimited. Among them, multi-touch computer monitors, TVs and other large-size terminal markets have begun to emerge. Continental manufacturers have developed capacitive touch screen technology. Capacitive touch screens have the characteristics of high light transmittance, durability and support for multi-touch, etc., and the future market prospects are better.
But on the other hand, the era of high profitability in the touch panel industry is over. The competition is getting fiercer and fierce, and the touch giants have also adjusted their industrial structure in response. Recently, Mudong Optoelectronics, which opted out due to increased industry competition, has become a hot spot of concern. In addition, the collapse of domestic small and medium-sized touch screen factories also shows that the touch industry has quietly entered the integration period.
Second, the development status of touch technology
The main technologies of projected capacitive touch panels with multi-touch applications are divided into two types: filmtype and glasstype. The Apple camp uses glass projected capacitors (glasstype) instead of the Apple camp. Mainly film projected capacitor (filmtypePET); the current mainstream film structure is ITO through photolithography or printing on the PET film, the outer layer is protective glass called GFF (Glass-Film-Film) structure, and the mainstream The glass structure is to make the touch sensor on ITO glass, and the outer layer plus a piece of protective glass is a GG (Glass-Glass) structure. The former is limited to the control of high-end ITO film materials in the hands of a few Japanese merchants, while the latter's GG bonding yield is generally low, which is the main reason for the high cost of projected capacitive touch modules.
In order to effectively reduce the cost of touch modules and at the same time meet the market trend of thin and thin end consumer electronic products, the touch industry has actively started to develop and reduce the amount of ITO film or ITO glass in the past two years, and developed OGS, in-cell touch or GF film technology. . OGS technology integrates ITO glass and protective glass into one piece of glass, which not only reduces one piece of glass, but also saves a laminating process. It is about 0.4 mm thinner than two-piece G / G products, and it is estimated that it can save about 50% of the cost.
At present, professional touch module manufacturers such as Chenhong, Shenghua, and Dahong are most actively developing OGS. Among them, Shenghua ’s OGS has the fastest mass production and shipment. It has been applied to smart phones of many international brand manufacturers in 2011. At the beginning, it was introduced to the domestic first-tier tablet computer manufacturers. In early 2012, the domestic touch industry also actively invested in the development of OGS products, and began to send samples to customers for certification. If breakthroughs in glass strengthening and production efficiency are achieved, OGS is expected to become the new mainstream of glass touch technology in the future.
Compared with the active layout of OGS technology for external professional touch module factories, the main TFT or AMOLED panel factories tend to develop in-cell technology (InCellTouch)
The sensor is directly built into the display, which can be roughly divided into two technologies: In-cell and On-cell. The advantages of embedded touch can also save a piece of glass and a laminating process, but because the introduction of embedded technology panel factory must have LTPS technology, the entry barrier is relatively high, and the current process yield is still low. The impact of the external touch panel is not significant.
However, with Apple's support for embedded technology, it has recently and actively cooperated with Japanese and Korean companies to develop it. At the same time, Samsung will also launch AMOLED application products with On-cell touch technology this year. The future of embedded touch is still not tolerated Xiao Xiao.
In 2012, under the competition of OGS and embedded technology, glass touch panels are setting off a wave of thin and thin touch technology market competition. The industry pointed out that under the OGS development trend, in addition to the original sensors and module factories, protective glass manufacturers and color filter factories also have the opportunity to enter the field of touch modules, and the revolution of the touch industry is ready. hair.
It is worth noting that Samsung and its third-party suppliers in South Korea have planned to build the latest OGS production line and are actively deploying relevant strategic supply chains. For example, key OGS sputtering equipment technology is expected to be provided by Taiwanese manufacturers. Ru precision came to provide. It is understood that Samsung Group may reverse the past procurement model of touch module factories and set up some touch production lines in its own house. It revealed that Samsung ’s change in the touch supply chain strategy is worthy of high attention from domestic players.
