Touch panel, touch display panel, and touch sensing method

Abstract

A touch panel including first electrode bands, second electrode bands, and a transparent dielectric material is provided. The first electrode bands are disposed on a first substrate and extended in a first direction, wherein each of the first electrodes has a plurality of first silts in the form of enclosed configuration. The second electrode bands are disposed on a second substrate, facing to the first electrode bands, and extended in a second direction interlacing the first direction. Each second electrode band is partially exposed by the first silts. The transparent dielectric material is disposed between the first electrode bands and the second electrode bands to provide a changeable gap.
