The working principle of the capacitive screen
Small amount of voltage is applied to the electrodes on the four corners . A human body is an electric conductor, so when you touch the screen with a finger, a slight amount of current is drawn, creating a voltage drop.
The current respectively drifts to the electrodes on the four corners. Theoretically, the amount of current that
drifts through the four electrodes should be proportional to the distance from the touch point to the four corners.
The controller precisely calculates the proportion of the current passed through the four electrodes and figures
Out the X/Y coordinate of a touch point.

Q. Can you give us a favorable discount ?
A: Of course, a favorable discount will be offered if the quantity is sizable.
Capacitive Touch Screen:
Capacitive touch screen is very different with traditional resistive touch screen. When the resistive touch screen works, you can only judge a touch point. And if there are two or more touch points, you can not make the right judgments. So the resistive touch screen applies only to judge a few simple actions such as click, drag and drop. The capacitive multi-touch screen can decompose the user's touch into colleting multi-point signal and determining the significance of the signals, and complete the judgments of complex action. Moreover, you can feel it when you lightly touch the projected capacitive touch sensor panel. Better durability, more than 90% light transmission rate, high transparency than the traditional resistive touch screen are the advantages of our products.
