touch lcd screen
touch lcd screen. When a finger touches the screen, the two conductive layers that are normally insulated from each other make a contact at the touch point. Because one of the conductive layers is connected to a 5V uniform voltage field in the Y- axis direction, the voltage of the detection layer changes from zero to Non-zero, after the controller detects this, it performs A / D conversion and compares the obtained voltage value with 5V to get the Y- axis coordinates of the touch point , and similarly obtains the X- axis coordinates. This is The most basic principle common to all resistive technology touch screens.
