The rapid spread of smartphones and tablets has allowed the scale of the touch industry to continue to grow. While actively implementing the industrial layout, touch panel manufacturers have also shifted their development focus to new products and technologies to expand the touch application market. Recently, at the 2014 Shanghai International Touch Screen Exhibition, the ITO replacement material technology of touch panel manufacturers was the most eye-catching, and the application of wearable devices in the field of touch began to emerge. Wang Jian, executive vice president of GIS of Yecheng Group, said in an interview with China Electronics News at the exhibition site that the era of comprehensive touch has arrived. In the emerging wearable field, touch technology is not a problem. The most important thing is how to apply technology to the life level. How to develop products that impress consumers is the key for manufacturers to explore the field of wearable touch.
The touch market is increasing in size
When the cost is reduced to a certain extent, the touch market will have more room for growth. Touch screen shipments are expected to increase by 15% in 2014.
Despite the 1% decline in the growth rate of touch screen output for the first time in four years, it still cannot hide the enthusiasm of manufacturers for the touch market. According to DisplaySearch statistics, the total touch industry shipments in 2013 were nearly $31.4 billion, an increase of nearly 30% year-on-year. Touch screen shipments will continue to grow by 15% in 2014.
Li Chao, sales director of ViewSonic Display Division, told the China Electronics News: “Where the monitors are used, they may be replaced by touch screens. The future growth of the touch market is still very impressive.†For the touch screen industry Development, Li Chao believes that the current cost of touch screens is still relatively high, especially in the display market, many consumers regard touch as an additional function. At present, the market for touch displays is growing slightly slower than the overall industry. When the price of touch screens drops to a certain level, the touch market will have even greater growth.
It is precisely because of the development prospects of the touch market that not only panel manufacturers are actively expanding into the touch screen field, but some small and medium-sized enterprises also hope to gain a share in the touch market, which makes the market competition increasingly fierce.
Gong Jiajun, project manager of Nanjing Huaruichuan Electronic Technology Co., Ltd., said in an interview with China Electronics News that Huaruichuan will plan two expansion plans in addition to the company's existing small and medium-sized production capacity. OGS is planned on the basis of CF project, and it is expected to be put into production in March 2015. Second, On-cell is planned on CLP Panda 8.5-generation TFT production line, which is realized by Sharp technology and is expected to be put into operation in 2015.
NPD DisplaySearch research director Xie Zhongli said: "Many touch screen manufacturers have made the industry more competitive, so even though panel shipments are still on the rise, the average shipping price and profit of modules has been declining, large-size touch screen modules. Production capacity (especially OGS) is oversupply. We predict that the shuffling of the touch screen industry has begun, some manufacturers are unable to obtain sufficient profits to survive, and some manufacturers are already seeking new directions, including a new generation of ITO (Indium Tin Oxide). Alternative materials and related processes."
Manufacturers actively develop ITO replacement technology
Manufacturers are actively developing better ITO replacement technologies, among which graphene, Metal Mesh and nano silver technology have become the focus of research and development.
In mobile phone touch screens, ITO is an indispensable material, but ITO also has problems such as high cost and difficulty in recycling. As technology continues to advance, touch manufacturers are looking for new alternative technologies. In the interview, the reporter learned that the current mainstream ITO replacement material technology includes Metal Mesh, nano silver, graphene, and organic conductive materials. Among them, Metal Mesh and nano silver technology are more feasible in mass production. Touch manufacturers' technology research direction, and graphene technology has good characteristics, many manufacturers are also actively developing technology.
Yang Shunlin, director of Shenzhen Yushun Electronic Technology, said that ITO has been developed for many years and has unique advantages. Among the alternative materials of ITO, nano silver has advantages in medium and large size, and the price is about 30% lower than that of ITO film; graphene application is better in small and medium size fields, and graphene film can be used to make foldable display touch. Control devices; Metal Mesh can be used in large-size FILM products with the advantage of being thin and light.
Peng Peng, vice president of Changzhou 2D Carbon Technology Co., Ltd., said in an interview with China Electronics News that the profit of ITO conductive film has been declining. Compared with ITO, graphene has more conductivity and light transmittance. Advantages, and flexible touch has a great advantage. However, the use of graphene materials for large-size touch screens has two limitations. First, the problem of production equipment. Graphene is not as mature as ITO equipment, and the efficiency of large-scale production is relatively low. Second, the conductivity of graphene is also Greater room for improvement.
At the exhibition, Changzhou 2D Carbon Technology Co., Ltd. exhibited a smartphone using graphene technology. According to Peng Peng, the graphene mobile phone has received orders from some small factories, but there are still no large-volume shipments. Although graphene is a new technology, although ZTE and Huawei have been paying attention to it, it is still cautious in terms of adoption. It takes a certain time for large manufacturers to accept graphene technology.
The reporter noticed that there are more and more touch screen products using Metal Mesh technology. Among them, Yeecheng Group GIS displayed the 84-inch Metal Mesh touch screen to seize the market that originally belonged to the infrared touch screen.
3M China Co., Ltd. National Senior Sales Manager Yu Ling said in an interview with China Electronics News that the biggest advantage of Metal Mesh technology is that it has a large size, especially the large-screen touch screen of 55 inches or more. The value is smaller than ITO.
Wearable display applications are gradually becoming directions
The application of touch technology to the wearable field has gradually become the consensus of manufacturers, which makes the flexible touch display usher in new development opportunities.
As wearable devices have gradually become a hot spot in the industry, the related supporting industries have also ushered in huge business opportunities. According to data provided by IHS, the sales of wearable displays will increase by more than 90% from 2014 to 2016. With the rapid increase in the adoption rate of Flexible and Stretchable in 2020, its annual sales growth rate will reach 52.9%, and the market size will also grow to 22.7 billion US dollars.
The reporter noted at the 2014 Shanghai International Touch Screen Exhibition that in the field of smart wearable devices, some manufacturers have already demonstrated products with touch functions, and the market prospect is broad. Both touch panel manufacturers and material manufacturers have prepared for wearable touch screens.
Peng Peng told the China Electronics News that wearable devices have gradually become a hot spot in the market. Flexibility is a direction for the future development of graphene. Although the wearable display has just developed, the package is not perfect, but as a touch transparent conductive material, graphene can be flexible display, which also brings a signal to the industry, touch technology is ready.
At the exhibition, Yecheng Group GIS demonstrated the application technology and products of water touch and 3D curved surface fitting. Wang Jianer told the China Electronics News that the water touch technology is made by using a thin film method, which can be waterproofed by improving the process touch module. The underwater touch module is planned to be applied to wearable products in the future. The technology is not a problem, but how to impress consumers, how to achieve more fine and more sensitive touch is a problem that has been explored by the GIS.
