With the development of information technology, touch screens, with their advantages such as ease of use, durability, fast response speed, and space saving, have made system designers increasingly feel that using touch screens does have significant advantages. What is touch screen and what types of touch screens are there? Let's learn more together! SIEMENS 6AV6643-0BA01-1AX0  Touch Screen What is a touch screen? Touch screen, also known as "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When touching graphic buttons on the screen, the touch feedback system on the screen can drive various connection devices according to pre programmed programs, which can replace mechanical button panels and create dynamic audio and video effects through the LCD display screen. As the latest computer input device, touch screen is currently the simplest, convenient, and natural way of human-computer interaction. It gives multimedia a new look and is a highly attractive new multimedia interactive device. Mainly used for public information query, leadership office, industrial control, military command, electronic games, ordering, multimedia teaching, real estate pre-sale, etc.   Allen-Bradley 2711P-RN6 Touch Screen What are the characteristics of a touch screen? 1) Transparency directly affects the visual effect of the touch screen. Transparency has a problem with the degree of transparency. The infrared technology touch screen and the Surface acoustic wave touch screen are separated by only one layer of pure glass, and transparency can be regarded as an outstanding one. Other touch screens need to be carefully studied. "Transparency" is a very general concept in the touch screen industry. Many touch screens are multi-layer composite films. It is not enough to summarize its visual effect by using transparency only. It should include at least four characteristics: transparency Color distortion, reflectivity, and clarity can be further divided. For example, the degree of reflection includes mirror reflection and diffraction reflection. However, the diffraction reflection on the touch screen surface has not yet reached the level of a CD drive. For users, these four metrics are basically sufficient. Beijer Mac Mta E700 Panel 2) The touch screen is an absolute coordinate system, and you can simply click on it wherever you want. The essential difference from relative positioning systems like mice is the intuitive nature of being in place at once. The output data of the same point on the touch screen is required to be stable under any circumstances. If it is not stable, then the touch screen cannot guarantee absolute coordinate positioning, and the point is inaccurate. This is the problem that the touch screen is most afraid of: drift. Technically, any touch screen that cannot guarantee the same sampling data at the same point of touch has the problem of drift. Currently, only capacitive touch screens have the phenomenon of drift. Mitsubishi GT1150-QBBD-C GOT1000 Touch Panel 3) Detect touch and locate. Various touch screen technologies rely on their own sensors for operation, and even some touch screens themselves are a set of sensors. The respective positioning principles and sensors used determine the response speed, reliability, stability, and lifespan of touch screens.
