Abstract

The invention discloses a touch control display panel. The touch control display panel includes a substrate, a drive circuit, and a touch control display array; the substrate includes a first zone and a second zone, wherein the first zone is positioned between the second zone and the drive circuit; the touch control display array includes scanning lines, data lines, first common electrodes, conductive patterns, and wires; the scanning lines and the data lines alternatively define sub pixels; the first common electrodes are arranged on the sub pixels of the first zone and the second zone, and the first common electrodes mutually connects each other to form touch control sensing pads; the conductive patterns are arranged in the sub pixels of the first zone; each of the wires is electrically connected to at least one touch control sensing pads; at least one wire in the first zone is overlapped with at least one first common electrode and at least one conductive pattern in a vertical projection direction; and each of wires in the second zone is covered by the first common electrodes in the vertical projection direction in part.

Description

technical field [0001] The present invention relates to a touch display panel, in particular to a touch display panel capable of reducing noise. Background technique [0002] Touch sensing technology has developed rapidly in recent years, and many consumer electronic products with touch functions have been launched successively. In such products, the original display panel area is mainly endowed with a touch sensing function, which can also be said to transform the original simple display panel into a touch display panel with a touch recognition function. Depending on the structural design of the touch display panel, it can generally be divided into out-cell and in-cell or on-cell touch display panels, in which the in-cell touch display panel is not It is necessary to make an additional touch panel to make the product thinner and lighter, and also save the cost of making the touch panel and thus have a price advantage. Since the touch elements of the in-cell touch display ...
