Abstract

The present invention provides a touch panel, comprising: a plurality of first electrodes parallel to the first axis; a plurality of second electrodes parallel to the second axis, wherein the plurality of first electrodes and the plurality of second electrodes are at a distance between the plurality of first electrodes and the plurality of second electrodes A plurality of sensing points are formed in the touch area; the first group of wiring harnesses outside the touch area include a plurality of first circuits to be respectively connected to the plurality of first electrodes and the touch processing device; in the touch area The second group of wiring harnesses outside the touch area includes a plurality of second circuits to be respectively connected to the plurality of second electrodes and the touch processing device; and the set of dummy electrodes outside the touch area includes one or more dummy electrodes, A space is formed between the part of the first group of wire bundles and the part of the second group of wire bundles, the set of dummy electrodes is located in the space, and the total area of ​​the set of dummy electrodes is smaller than the area of ​​the space.

Description

technical field [0001] The invention relates to a touch panel, in particular to a touch panel capable of reducing electromagnetic interference caused by dummy electrodes between wiring harnesses and wiring harness circuits. Background technique [0002] Touch panels or screens are the main input and output devices of modern electronic systems, and capacitive touch panels have good detection characteristics and have become one of the mainstream products in touch panel design. [0003] like figure 1 As shown, a typical capacitive touch panel 100 usually includes a touch area 110 . The touch area 110 includes a plurality of first touch electrodes 111 parallel to a first axis or a horizontal axis and a plurality of second touch electrodes 112 parallel to a second axis or a straight axis. The touch electrodes 111 and 112 must be connected to the touch processing device in order to operate the touch function. Therefore, in the area of ​​the glass panel or the flexible board out...
