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.
