The industrial flat panel touch display is an intelligent terminal with a microprocessor, which is generally used in industrial occasions to realize information interaction between humans and machines, including text or graphic display and input functions. At present, there are also a large number of industrial flat-panel touch screen displays that are widely used in non-industrial fields such as smart buildings, smart homes, urban information management, and hospital information management due to their mature industrial flat-panel touch screen displays and high reliability.
Therefore, industrial flat-panel touch screen displays are To develop into a more widely used high-reliability intelligent information terminal.
According to different functions, industrial flat panel touch screen displays are traditionally divided into three categories: text displays, touch screen man-machine interfaces, and tablet computers. The text display is generally controlled by a single-chip microcomputer, and the graphical display function is weak and the cost is low. It is suitable for low-end industrial man-machine interface applications. The touch screen man-machine interface adopts a higher-level embedded computer design. At present, the more popular design is to use a 32-bit ARM microprocessor with a main frequency above 100MHz and an embedded operating system such as Linux or WinCE.
