Abstract

The invention provides a capacitive touch structure and a scanning method. The capacitive touch structure can control a switching cell to be on and off to achieve purposes that two adjacent rows of touch detection electrodes simultaneously detect a touch position and / or two adjacent lines of touch detection electrodes simultaneously detect the touch position, i.e., binding overlapping type row scanning or binding overlapping type line scanning can be realized. Through the switching cell, two touch detection electrodes in a line direction or row direction can be connected to form a touch detection electrode cell, the influence of a line gap and a row gap between adjacent touch detection electrodes for touch accuracy is lightened, the touch accuracy of a touch pen is improved, and the degree of linearity of the touch pen is improved.

Description

Technical field [0001] The present invention relates to the field of touch technology, and in particular to a capacitive touch structure, a touch display panel, a display device and a scanning method Background technique [0002] With the rapid development of display technology, touch display devices have gradually spread throughout people's lives. In the initial stage of the development of touch display, the touch display panel is formed by bonding the touch panel and the display panel to realize the touch display. It is necessary to prepare the touch panel and the display panel separately, which is costly, relatively thick, and Low production efficiency. With the development of touch display technology, an in-cell touch display panel has appeared. The in-cell touch display panel embeds touch detection electrodes inside the display panel, which can reduce the overall thickness of the module and greatly Reduce the manufacturing cost of touch display devices, making them favored...
