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.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a capacitive embedded touch screen, a touch positioning method and a display device thereof. Background technique [0002] With the rapid development of display technology, capacitive in-cell touch screens have gradually spread in people's lives. An existing capacitive embedded touch screen is realized by directly adding a touch sensing device on the existing array substrate. The touch sensing device generally uses two strip electrodes interacting with different surfaces as touch scanning lines respectively. And the touch sensing line, the touch sensing capacitor is formed at the junction of the two electrodes, but this will increase the complexity of the process and reduce the aperture ratio. The touch scanning signal is loaded through the touch scanning line, and the touch sensing signal sensed by the touch sensing line through the touch sensing capacitor is detected. Dur...
