It has been more than ten years since China’s touch screen market began to rise in the late 1990s. Touch technologies have also emerged one after another. The characteristics of various touch screens are also mixed. The current mainstream touch technologies in the domestic market should be infrared, surface acoustic wave and resistive screen However, these technologies also have flaws, such as sonic screens that require force to click, and unstable performance of resistive screens. The emergence of optical touch screens has basically solved many touch screen problems and has sufficient conditions to lead the future touch market.

First, the optical touch technology is superior to the existing technology in terms of response speed and touch accuracy. Among the many existing touch technologies, infrared technology is superior to other technologies in response speed, sensitivity and touch strength, and it is slightly inferior to optical technology (because everyone knows that the propagation speed of light is 3X108m/s, its response Speed ??is of course second to none).

Secondly, in terms of size, the optical touch screen can be more than 250 inches, and the production cost will not increase significantly as the size increases. Compared with other technologies, the larger the size, the more obvious the price advantage.

The most important point is that, from the perspective of IT industry development trends, Microsoft's future new version of the operating system will vigorously support the use of touch technology, and intends to civilianize touch technology. Including some of the operating system's accompanying application software, such as touch pen tablet, two-point touch and so on.

All in all, the installation of digital signage systems mainly depends on execution, and only those manufacturers who can always pay attention to their customers will eventually win. Through the continuous innovation of the digital signage system, the brand will be continuously improved, and the continuous attention to new technologies will achieve good returns.
