Abstract

The invention provides a touch display panel, which comprises a color-film substrate, an array substrate and a liquid crystal layer, wherein a color-film color barrier and a common electrode are arranged on the color-film substrate; a data line, a scanning line, a thin-film transistor and a pixel electrode are arranged on the array substrate; the liquid crystal layer is arranged between the color-film substrate and the array substrate; the common electrode comprises a plurality of strip-shaped sub-common electrodes which are distributed in parallel; and when the touch display panel carries out a touch operation, the common electrode is used as a touch induction electrode and the scanning line is used as a touch drive electrode. The invention further provides a touch display device. According to the touch display panel and the touch display device provided by the invention, the common electrode is used as the touch induction electrode and the scanning line is used as the touch drive electrode, so that extra touch wire arrangement is reduced; and the manufacturing cost of the touch display panel and the touch display device is reduced.

Description

technical field [0001] The present invention relates to the field of touch display, in particular to a touch display panel and a touch display device. Background technique [0002] With the rapid development of display technology, touch screens (TouchScreenPanel) have gradually spread in people's lives. [0003] At present, the existing capacitive in-cell touch display screen is realized by directly adding touch scanning lines and touch sensing lines on the existing thin film transistor (ThinFilm Transistor, TFT) array substrate, that is, fabricating on the surface of the TFT array substrate. Two layers of strip electrodes intersecting on different planes, these two layers of electrodes respectively serve as touch driving lines and touch sensing lines of the touch screen, and the touch driving lines and touch sensing lines form mutual capacitance at the intersections of different planes. [0004] However, due to the need to add additional touch wiring, that is, touch drivin...
