Problems solved by technology

[0002] In flexible displays, due to the thinner packaging film, the touch electrode in the touch panel and the cathode under the packaging film form a large parasitic capacitance. The mutual capacitance value between the electrodes (TX) is reduced, which is likely to cause the problem of insensitivity to touch, and when the size of the panel is larger, the parasitic capacitance will increase significantly, resulting in a significant decrease in touch performance
[0003] Therefore, the research on the touch module needs to be deepened

Abstract

The invention provides a mutual capacitance type touch module and a touch panel. The mutual capacitance type touch module comprises an insulating substrate, wherein a plurality of touch units are arranged on the surface of the insulating substrate. Each touch unit comprises a first electrodes and a second electrodes, wherein the first electrode is annular, and the second electrode is arranged around the first electrode and is insulated from the first electrode at an interval. Therefore, since the second electrodes are arranged around the first electrodes, every place of the first electrodes are provided with the second electrodes overlapped with the first electrodes; i.e., the overlapping length between the first electrodes and the second electrodes can be greatly increased, so the mutualcapacitance value between the first electrodes and the second electrodes is effectively increased, parasitic capacitance generated between the first electrodes and / or the second electrodes and other non-touch electrodes is relatively small; and therefore, touch performance is optimized, the problem of poor touch is solved, and particularly, the problem of insensitive touch of medium and large-sizedisplay panels can be obviously solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a mutual capacitive touch module and a touch panel. Background technique [0002] In flexible displays, due to the thin thickness of the encapsulation film, the touch electrodes in the touch panel and the cathode under the encapsulation film form a large parasitic capacitance. The decrease of the mutual capacitance value between the electrodes (TX) is likely to cause the problem of insensitive touch, and when the size of the panel is larger, the parasitic capacitance will increase greatly, resulting in a significant decrease in the touch performance. [0003] Therefore, the research on the touch module needs to be in-depth. SUMMARY OF THE INVENTION [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an object of the present invention is to provide a mutual capacitive touch with touch ...
