13.3 inch touch screen protector.Development Trend of Resistive Touch Screens in Mainland China The local touch screen manufacturing industry in Mainland China started late compared to Japan, South Korea and Taiwan. Some of the original manufacturers were mainly located in the Pearl River Delta region, and their scale was relatively small. Most of the products they supplied were concentrated in the middle and low-end areas. Most of them mainly produced resistive touch screens. This type of compound growth is much higher than the growth of other technologies, so many have poured into this area for production and sales, and their manufacturing enterprises are basically private or Taiwanese enterprises. However, due to the small scale, the technical background is not deep, and the production environment and related conditions are relatively crude. Therefore, there is a large gap from international standards in terms of technology improvement and quality control. Most manufacturers still focus on the production of digital touch screens. The touch screen involves less. Due to its small production capacity, poor quality stability, and insufficient large-capacity throughput, it affects the foundry cooperation with major manufacturers in Japan and South Korea. These adverse factors will ultimately limit its long-term development. In recent years, the Yangtze River Delta has gradually gained the upper hand in the game with the Pearl River Delta, and its status as a world processing plant has been looming. Numerous international giants have settled in Shanghai, Suzhou, Wuxi, and Nanjing, such as LG Philips, Sharp, BenQ, AUO, Canon, Seiko Epson, Hanyu, Lite-On and many other giants, which have formed a huge in this area. New display industry group. For touch screen manufacturers, this huge industry group contains strong real and potential needs. At the same time, this also puts forward new requirements for touch screen manufacturers. As the three major factors that cannot be ignored, geographical advantages, technological advantages, and production capacity advantages will definitely play an important role in the development of touch screens. In the past, small workshop-style production methods need to be considered again. The method that can be used only by a few so-called "standard" products will not be welcomed by the market anymore. The way to impress users with low prices will inevitably set off the market, because Whether from the manufacturer's perspective or the user's perspective, quality is fundamental to the smooth implementation of product features. Looking at the current types of touch screen products at home and abroad, in terms of the most practical resistive touch screens, the specifications of their products range from IQTouch K interactive touch screen feature 20-point touch and dual system -- Android 8.0 system and optional OPS Windows 10Pro system. Its 4K UHD resolution facilitates presentations and collaboration. With optional multi-screen casting software, IQClass 6.0 and installation-free IQClass Plus software, IQTouch K Series can help create an interactive and collaborative teaching atmosphere in class.
