US 10,372,264 B2 · Touch panel including touch sensor and driving method thereof

Abstract

A touch panel including: a first electrode pattern arranged in a first direction, including a plurality of first electrode cells that are physically separated from each other; a second electrode pattern arranged in a second direction crossing the first direction, including a plurality of second electrode cells that are physically separated from each other; first touch signal lines connected to the first electrode cells; and second touch signal lines connected to the second electrode cells. The electrode patterns and the touch signal lines are arranged on the same layer on a substrate such that a first virtual connection line for connecting centers of second electrode cells of a first group corresponding to an n-th first electrode cell crosses a second virtual connection line for connecting centers of second electrode cells of a second group corresponding to an (n+1)-th first electrode cell.
