Optical touch screen market prospects
China touch screen market began to rise from the late 1990s it has been more than ten years, the touch technology is endless, and the touch screen features several advantages and disadvantages, the current domestic market mainstream touch technology when infrared, surface acoustic wave, and resistance screen , but several techniques exist flaws, the acoustic screen click need strength, resistance screen performance is unstable, and so on. The emergence of optical touch screen basically solved the problem of many touch screen, and a sufficient condition for the leadership of the future touch market.Lcd display modules 
First, from the reaction rate and touch precision optical touch technology is superior to the prior art. In many existing touch technology, infrared technology reaction speed, sensitivity and touch intensity superior to other techniques, which slightly inferior (because we all know dynasty propagation speed is the of 3X108m / s as compared with the optical technology, and its reaction speed, of course, is second to none); Second, from the size of, say, 250-inch optical touch screen can be done more, and increase the size of its production costs, will not have a significant increase in Relative to other technologies, the larger the size, the price advantage is more obvious; most important, from the IT industry trends point of view, Microsoft's new operating system, major efforts to support the use of touch technology and touch technology intends to civil technology. Including some operating systems with applications such as touch tablet, two touch.
