Detection and positioning Various touch screen skills are based on sensors, and even the touch screen itself is a set of sensors.
The respective positioning principles and the sensors used in each case determine the response speed, reliability, stability and service life of the touch screen.
Bright function The touch screen is composed of multiple layers of composite film,The quality of brightly lit function directly affects the visual effect of the touch screen。
Brightness measurements depend not only on the touch screen visual effect,It should also include four characteristics of transparency, color distortion, reflectivity and sharpness.
Affirmative coordinate system,Our traditional mouse is a relative positioning system,Only related to the orientation coordinates of the previous mouse.
The touch screen is an affirmative coordinate system.To choose which directly point where,Substantial difference from relative positioning system.
The characteristic of the affirmative coordinate system is that each positioning coordinate has no relationship with the previous positioning coordinate.Each touch of the data is calibrated to the coordinates on the screen。
No matter under what circumstances,The output data of the touch screen at the same point is stable.But because of the principle of skill,Can not ensure the same point touch each sample data is the same.
Can't guarantee positive coordinate positioning, inaccurate touch, this is the most terrible problem of touch screen,Regarding the touch screen with good function quality, the drift situation is not very serious.
