MUTUAL CAPACITIVE TOUCH SENSING DEVICE OF TOUCH PANEL

摘要

A mutual capacitive touch sensing device of a touch panel includes a plurality of touch sensing groups arranged along a first direction. Each touch sensing group includes a first electrode, a plurality of second electrodes and a plurality of third electrodes. The first electrode is disposed on a substrate in a serpentine shape, and includes a first side and a second side that are opposite. The first side includes a plurality of first indentations, and the second side includes a plurality of second indentations, with the first indentations and the second indentations alternately arranged along a second direction. One of the first indentations and one of the second indentations that are adjacent do not overlap in the first direction. The second electrodes are respectively disposed in the corresponding first indentations, and the third electrodes are respectively disposed in the corresponding second indentations.
