Touch screen application upgrade China welcomes industry opportunities
The new experience, smooth touch effect, touch screen technology equipped with "Apple" company's iPhone, iPad series products in the consumer electronics field shines and is popular all over the world. In fact, touch screen technology has appeared in the 1970s. It was used in industrial control and commercial equipment in the early days. In recent years, it has been rapidly infiltrating into the field of consumer electronics. The expansion of touch screen applications has ushered in a good opportunity for the Chinese touch screen industry. .
At present, the mainstream touch screen control technologies mainly include: resistive, capacitive, optical and surface acoustic wave. Optical and surface acoustic wave are mainly used in the field of medium and large size touch screens. The touch screen technology with the highest market share is still resistive. Thanks to the hot selling and multi-touch technology of iPhone and iPad, the application of projected capacitive touch screen technology has developed rapidly, and its market share is fast. increase.
Compared with the resistive touch screen control technology, the capacitive touch screen control technology is more sensitive, does not rely on the stylus, and does not have the problem of inaccurate screen drift positioning, high display brightness, easy to achieve multi-touch, etc. Development potential.
1. China's touch screen industry scale
At present, the global touch screen industry chain pattern has taken shape. From the perspective of the distribution of major enterprises, the Chinese touch screen industry is gradually entering the global industrial layout. China's Laibao High-Tech, Ultrasonic Electronics, Luobo, Qirui Microelectronics, and Pier Technology have entered the industrial chain.
According to the size of the touch screen, the application area of ​​the touch screen can be divided into small and medium size (below 10.1 inches) and large size (10.1 inches or more) according to the size of 10.1 inches. Large size is mainly used in ATM, POS, KIOSK, and small and medium size is mainly used in mobile phones, GPS navigation devices, PDAs, tablets and other consumer digital products. At present, the development of China's touch screen industry is mainly concentrated on small and medium-sized personal consumer electronic products. Touch screen mobile phones and tablet computers are currently the application hotspots of small and medium-sized touch screens, and are also the most important application fields of the Chinese touch screen industry.
In 2010, the scale of China's touch screen industry reached 67.67 million, a sharp increase of 98.0% compared with 2009, showing explosive growth. At present, the penetration rate of China's touch screen industry in electronic equipment products is still at a stage of high growth. From the perspective of the industry life cycle, there is still huge room for development.
From the perspective of product structure, in 2010 China's touch screen industry, resistive touch screen still dominates, with an industrial scale of 38.766 million pieces, accounting for 57.3%. The output of capacitive touch screens has increased dramatically. In 2010, the capacity of the capacitive touch screen industry was 22.237 million, accounting for 32.9% of the total output, compared with 3.4 times in 2009, mainly due to Apple's iPhone and iPad. Large-scale application of capacitive touch screens brought by capacitive touch screen technology.
From the perspective of application structure, China's touch screen industry in 2010 is mainly divided into mobile phones, tablet computers, navigators, digital cameras, MP3/MP4/PMP, large-size applications, etc., where the mobile phone field is still the focus of touch screen development. The output of touch screen reached 41.65 million pieces, accounting for 61.4% of the total touch screen output. As a result of the hot sales of iPad, the output of tablet touch screens also increased significantly, reaching 8.084 million pieces, an increase of 7 over 2009. More than double, it has become a shining highlight of the development of touch screen applications.
2. China's touch screen control chip market structure
At present, China's touch screen control chip market includes touch chip products from suppliers such as Atmel, Cypress and Synaptics. Among them, Synaptics is a leading player in the touch screen control chip market. Atmel and Cypress are also actively involved, and other latecomers are also involved. At present, China's capacitive touch screen control chip market is still dominated by these foreign companies. Local companies such as Duntai Technology and Qirui Microelectronics have already had certain competitive strength, but the overall competitiveness of China's touch screen control chip companies has yet to be improved.
3. Development trend of China's touch screen industry
China's touch screen industry will show a rapid development momentum. The consumer electronics fields such as smart phones and tablet PCs are still the key areas for the development of the touch screen industry. The development prospects of touch screens in the small and medium size fields are very optimistic, and it is also the current and next stage touch screen industry. The main development direction, in the large size field, touch screen in the public query system, self-service system and other fields will also accelerate the pace of development.
From the perspective of technology development, multi-touch technology has become a hot spot, and its influence and penetration rate are increasing, which has led to the rapid growth of demand for projected capacitive touch screens. Due to its superior performance, continuous improvement of technology and cost reduction, Its development speed is gradually accelerating.
