Abstract
The present disclosure provides a capacitive built-in touch screen, its touch positioning method, and a display device. In the capacitive built-in touch screen, at least one of the gate lines is set as a touch scanning line, and the capacitive built-in touch screen further includes at least one touch sensing line arranged on the array substrate. The touch scanning line intersects the touch sensing line in different planes. The touch sensing line is configured to, when a scanning signal is applied to the touch scanning line, couple the scanning signal through a touch sensing capacitor to obtain and output a touch sensing signal. The touch sensing capacitor is arranged at an intersection of the touch scanning line and the touch sensing lines on different planes.
