For high-frequency current, capacitors direct conductor, so the finger from the contact point to a very small current Current outflow from the electrodes on the four corners of the touch screen, and flows through four electrodes with finger to the four corners proportional to the distance, the controller through the accurate calculation of the four current ratio, draw the location of the touch points. The capacitive touch screen schematic: compared to traditional resistive touch screen, capacitive touch screen advantages are mainly the following aspects: new operation. The capacitive touch screen supports multi-touch operation more intuitive, more fun.
Occupies a proportion of maintenance is very high, from principle to the detected replacement (substitution) friends do not know how to change the touch screen to talk about the maintenance of my personal experience, I hope to help the novice, if what I make a mistake place, hope the wing of the heroes. One: the general principle we see the touch screen are four feet, we were known as the X, X1, Y, Y1,; X and Y, X1 and Y1 is a group, a group responsible for the horizontal coordinate detection , a group responsible for the vertical coordinate detection, due to the resistance value of each line according to the length of the distance is not the same, when we point at any point location, it will be X and Y, X1 and Y1, two sets of lines intersect, due to distance of the location of each point. cell phone jammer are used in different locations for different purposes. There is, replace the touch screen, preferably after another line on the touch screen calibration, do not obviously connected, but because no calibration made detours. At present, with the launch of the smart phone as well as becoming more common, more and more frequent touch-screen mobile phone / PDA, but also more and more important. The next picture shows the professional bodies to provide touch-screen market demand forecast, mainly use the comparison of the proportion of the product touch screen touch screen manufacturers market share comparison in 2003 and 2003. Visible use of the touch-screen mobile phones and other handheld products will become increasingly common, but the touch screen design applications, there is no related norms and standards, poor quality and other issues in the pre-project development and production process.
