Abstract
A touch panel includes a touch layer, a first Indium Tin Oxide (ITO) electrode layer, a second ITO layer, and a microcapsule layer. The first ITO electrode layer includes a plurality of first ITO electrode. The second ITO electrode layer includes a plurality of second ITO electrodes. Each of the first ITO electrodes and one corresponding second ITO electrode forms an electrode unit. The microcapsule layer includes a plurality of microcapsules. Each microcapsule is connected to the first ITO electrode and the corresponding second ITO electrode. Each microcapsule comprises a plurality of positively charged particles and negatively charged particles. When the touch panel is touched, the distribution of the positively and negatively charged particles in the microcapsule corresponding to the touch portion of the touch layer is placed in a polarization state. An electronic device using the touch panel is also provided.
