II、The principle of capacitive touch panel:
The capacitive touch panel is the electric capacitance between the transparent electrode and the human body.
Touch panel induction principle to effect on the induction voltage of four corners, and form a fixed electric field when a finger touch screen, can make the electric spark current, by determination of controller, according to the difference of the proportion of current from four angles, to calculate the contact position.However, the capacitive touch panel must overcome the noise caused by static electricity generated by finger or other touch media, so it is difficult to design the current and structure.The position can be calculated according to the current ratio when subjected to contact pressure.
Elements of capacitive touch panel is, on the glass substrates coated with a layer of conductive layer, and then making electrode layer, and finally in the surface layer covering a layer of protective film, the capacitive touch panel is completed, because it only on a single piece of glass electrode, the conduction.The resistive touch panel needs to be superimposed on the ITO transmission layer of the upper plate and the lower plate, which affects the light transmittance of the overall touch panel. Therefore, the capacitive transmittance is higher than the resistive type, which can reach over 90%.The product is fireproof, anti-fouling and scratchable, and anti-dust and reaction speed are better.
