Abstract

The present invention provides a touch panel including: multiple first electrodes being parallel to a first axis; multiple second electrodes being parallel to a second axis, wherein multiple sensing points are formed in a touch area by the first electrodes and the second electrodes; a first bus laid outside the touch area including multiple first circuits respectively coupled to the first electrodes and a touch sensitive processing apparatus; a second bus laid outside the touch area including multiple second circuits respectively coupled to the second electrodes and the touch sensitive processing apparatus; and a dummy electrode set laid outside the touch area including one or more dummy electrodes, wherein a separate area is formed between a part of the first bus and a part of the secondbus, the dummy electrode set is laid inside the separate area, and the total area of the dummy electrode set is less than the area of the separate area.

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...
