ITO Sputtering targets manufacturers are facing new business opportunities



China Touch Screen Network News, touch screen technology was born in the US military in the 1970s.In recent years, iPod music players and later derived iPhones have become the driving force behind the development of touch screens..With these two new applications taking the world by storm, they have greatly promoted the development of touch screens..iSuppli has predicted that the global shipments of major touch screen technologies in 2012 will rise from US$2.4 billion in 2006 to US$4.4 billion..Faced with such rapid growth, touch screen technology and industry are also changing and developing rapidly.Due to the expansion of production by major manufacturers, the two main types of touch screen technologies-resistive and capacitive touch screens used ITO film suppliers are limited, which has caused the touch screen market to be plagued by the shortage of ITO (Indium Tin Oxide) film supply in the past two years..


The demand for touch screens has increased significantly, and the upstream ITO conductive film production capacity has lag


Jiangnan Securities analysts believe that in 2007, the demand for touch screens increased significantly, while the upstream ITO conductive film production capacity growth rate was lagging, resulting in tight supply, and related manufacturers obtained higher interest rates..Jiangnan Securities analyzed that after the PDA market bubbled in 2002, the supplier of touch screen materials did not expand production for a long time..


According to the data of Displaybank, the total global production of ITO conductive film in 2007 increased by only 13 year-on-year..4%.In 2007, there were already touch screen manufacturers subject to upstream ITO conductive film supply restrictions, and capacity expansion was hindered.In 2008, the total output of ITO conductive film increased by 71.2%, especially among the leading manufacturer Nitto Denko, began to expand production capacity in April 2008.


In 2008, the supply of ITO conductive film shifted from a short supply in 2007 to a balance between supply and demand.Hong Jinwei, President of Suzhou Hanrui Microelectronics Co., Ltd., in an interview with a reporter from China Electronics News, believes that the current supply of ITO film is becoming normal..At present, the mid-to-high-end film production technology is mainly in the hands of Japanese manufacturers, such as Nitto Denko, Oike Industry, etc., in the future, other materials, such as conductive polymers, carbon nanotubes, ATO (AntimonyTinOxide) and other material manufacturers other than ITO film If you can solve the problems of light transmittance and square resistance well, you have a chance..Similarly, domestic ITO manufacturers have the same opportunity to participate in market competition if they can solve these technical problems..


Domestic ITO target manufacturers have fierce competition, touch screens provide new development space


After more than 20 years of development, my country’s ITO industry has entered a mature period, but due to the rapid development of its downstream display industry, new opportunities and new development trends continue to appear in the ITO industry..There are two trends for ITO film in the future. One is that the LCD panel manufacturer will complete it by itself and no longer need an external processing factory to provide coating products; the other is an external processing factory for its support. The currently visible application is the touch screen. The touch screen changes from resistance to capacitance. Coated products provide new development space.


Due to the sufficient production capacity of low- and mid-end ITO products, high-end products such as ITO conductive glass for touch screens are becoming a new hot spot for domestic ITO manufacturers. Domestic manufacturers are working hard to improve the level of research and development and product quality to deal with new business opportunities.The relevant person in charge of Leybold said in an interview with the reporter of “China Electronics News” that at present, there are more domestic ITO manufacturers. In order to avoid price wars, differentiated competition is the way for enterprises to go..Touch screen is a new application field that Leybold pays close attention to.


The relevant person in charge of CSG introduced in an interview with a reporter from “China Electronics News” that CSG is currently a relatively large glass production group in China, and CSG is mainly positioned for high-end ITO conductive glass business, mainly STN and touch screen related products..”At present, the overall application market of ITO glass has not grown significantly. Now we need to find new applications. Touch screens are a new direction..”The person in charge said.


Integrate industry chain resources to develop my country’s touch screen industry


Touch screens are everywhere around us. There are currently several types of touch screens: resistive, capacitive (surface capacitive and inductive capacitive), surface acoustic wave, infrared, bending wave, and active digital conversion. Device type and optical imaging type.

They can be divided into two types. One type requires ITO, such as the first three types of touch screens; the other type of structure does not require ITO, such as the latter types of screens..Currently on the market, resistive touch screens and capacitive touch screens using ITO materials are the most widely used.


Nitto Denko, a manufacturer of high-end touch screen films, invested 1.8 billion yen in 2007 to increase production of electrode films for touch screens.It is understood that the company’s electrode film consists of two layers of polyethylene terephthalate (PET) and a transparent electrode ITO layer (indium tin oxide)..By making PET into two layers, durability and input performance are improved, and input can be realized with a touch.In April 2008, the company tripled its production capacity.


From the current point of view, there is still a long way to go for ITO manufacturers in my country to truly enter the field of touch screens..From the perspective of the development history of touch screens, touch screens show periodic development characteristics.Objectively speaking, the growth of the touch screen market this round has brought a rare opportunity for development and transformation of domestic manufacturers..Domestic related manufacturers that have developed greatly in the STN/CSTN era have been suppressed by TFT in the past two years, and their business growth has been hindered..Driven by the current development of the touch screen market, many of the coating technologies previously mastered have achieved a magnificent turn and ushered in a new high-speed business growth..
