Abstract
A capacitive touch panel and a display device using the capacitive touch panel are provided. The capacitive touch panel includes a first electrode layer, a second electrode layer, and a dielectric layer disposed between two layers. The first electrode layer has a plurality of first A electrode strings and first B electrode strings extended along a first direction. The first A electrode string and the first B electrode string respectively has a plurality of first direction electrodes. The second electrode layer has a plurality of second direction electrodes connected in series along a second direction. The first A and B electrode strings are disconnected in the first electrode layer while they are simultaneously detected for presence of signal variation.
