Capacitive touch panel with low coupling capacitance and display device using the capacitive touch panel
A capacitive touch panel and a display device using the capacitive touch panel are provided. The capacitive touch panel includes a plurality of first direction electrode strings and second direction electrode strings. Each first direction electrode string has a plurality of first electrodes while each second direction electrode has a plurality of second electrodes. In order to reduce the lateral capacitance between adjacent electrodes, width of the first electrode is reduced from the middle to two sides of the electrode along a second direction. In addition, the first electrode has a perimeter surrounding itself. Each quarter of the perimeter of the first electrode facing the adjacent second electrode has a first slope change rate and a different second slope change rate.
