Touch screen structure - automatic group installation
The automatic group installation touch screen is composed of multi-layer composite film, which directly affects the visual effect of the touch screen. The transparent performance of the touch screen should be measured not only by its visual effects, but also by the four characteristics of transparency, color distortion, reflective and sharpness.
Automatic group installation detection and positioning
The automatic group of installed touch screen technology relies on the sensor to work, even the touch screen itself is a set of sensors. Their respective positioning principles and their respective sensors determine the speed, reliability, stability and longevity of the touch screen.
Absolute coordinate system of automatic group
Our traditional mouse is a relative positioning system, which is only related to the position coordinates of the previous mouse. The touch screen is an absolute coordinate system, which can be selected directly, which is fundamentally different from the relative positioning system. Absolute coordinate system is the feature of every location coordinates has nothing to do with the last position coordinates, every touch data through calibration into screen coordinates, no matter under what circumstances, this touch screen coordinates, at the same point output data is stable. But because of technical principle, there is no guarantee that the same point touch every sampling data of the same, cannot guarantee absolute coordinates positioning, point, this is the most afraid of touch screen problem: drift. For a touch screen with good performance, the drift is not very serious.
