Parallelogram electrode touch panel

摘要

A touch panel including multiple electrodes is provided. The electrodes form a sensing area and are disposed on a same plane. The sensing area has a first border and a second border that are substantially perpendicular to each other. The electrodes include one parallelogram electrode. The parallelogram electrode has two first sides parallel to the first border and two second sides parallel to neither the first border nor the second border.

1. A touch panel, comprising:
a plurality of electrodes, forming a sensing area having a first border and a second border substantially perpendicular to each other, disposed on a same plane, comprising:
a parallelogram electrode, having two first sides parallel to the first border and two second sides parallel to neither the first border nor the second border; anda right-angle triangle electrode, having a hypotenuse and two legs, wherein the hypotenuse is parallel to the two second sides of the parallelogram electrode, and one of the legs is parallel to the second border; and a connecting wire corresponding to the parallelogram electrode extending from an angle of the parallelogram electrode closest to the second border, wherein capacitance changes generated by the parallelogram electrode are used for calculating both a first direction coordinate and a second direction coordinate of a touch position.
