Prodduct process:
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.
