Features Of Touch Screen
Today we're going to talk about the features of touch screens:
The first feature of the touch screen: transparency
It directly affects the visual effect of the touch screen. Transparency has the degree of transparency, in the touch screen industry, this is a very general concept, we know that many touch screens are multi-layer composite film, only with a transparent point to summarize its visual effect is not enough, it should include at least four characteristics: transparency, color distortion, reflective and clarity.
The second feature of the touch screen is the absolute coordinate system
Absolute coordinate system is the feature of every location coordinates has nothing to do with the last position coordinates, touch screen in physics is a set of independent coordinate positioning system, every touch of data through the calibration data into screen coordinates, so that this requires a touch screen coordinates, no matter under what circumstances, the same point of the output data is stable, if not stable, so the touch screen can't guarantee the absolute coordinates positioning.
The third feature of touch screen: detection of touch positioning
Various touch screen technologies rely on their own sensors to work, and some touch screens are even a set of sensors themselves. The reaction speed, reliability, stability and life span of the touch screen are determined by the positioning principle and the sensors used respectively.
