Today we are going to talk about the features of the touch screen:
The first feature of the touch screen is transparency
The visual effect of the touch screen is directly affected. Transparency is 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, just a transparent point to summarize its visual effect is not enough, it should include at least four characteristics: transparency, color distortion, reflection and clarity.
The second feature of the touch screen is the absolute coordinate system
Absolute coordinate system is the feature of each position coordinates has nothing to do with the final location coordinates, touch screen in physics is a set of independent coordinate positioning system, every touch data through the calibration data into screen coordinates, so it will need a touch screen coordinates, in any case, the output of the same point data is stable, if not stable, Then the touch screen cannot guarantee absolute coordinate positioning.
The third feature of touch screen: touch positioning detection
Touch screen technologies rely on their own sensors to work, and some touch screens are even a group of sensors themselves. The response speed, reliability, stability and life of the touch screen are determined by the positioning principle and the sensor used.
