TOUCH PANEL

摘要

In one embodiment, a touch panel includes a substrate, a plurality of first and second sensing units, a plurality of wirings, a touch circuit unit, and at least one impedance adjustment means. The substrate has an active area and a peripheral area. The sensing units are disposed in the active area. The wirings are disposed in the peripheral area. The first sensing units and the plurality of wirings form first sensing channels, and the second sensing units and the plurality of wirings form second sensing channels. Impedances corresponding to the first or the second sensing channels are adjusted to substantially approximate a consistent impedance by using the impedance adjustment means.
