Touch screen and touch display electronic device

Abstract

The invention discloses a touch screen and a touch display electronic device. The touch screen comprises a substrate, an auxiliary electrode layer, a common electrode layer and a routing layer, wherein the auxiliary electrode layer, the common electrode layer and the routing layer are arranged on the same side of the substrate, and the common electrode layer and the routing layer are oppositely arranged in the direction perpendicular to the substrate. The common electrode layer comprises a plurality of common electrode blocks which are the same. Each common electrode block comprises a center electrode and a sawtooth electrode electrically connected with the center electrode. The opposite sawtooth electrodes of every two adjacent common electrodes are nested. The routing layer comprises a plurality of first wires electrically and correspondingly connected with the common electrode blocks in a one-to-one mode. The auxiliary electrode layer comprises a plurality of auxiliary electrode blocks. The sawtooth electrodes adjacent to the edge of the substrate and the auxiliary electrode blocks are nested. When the common electrode blocks input common voltage signals for image display control, the auxiliary electrode blocks input common voltage signals. The touch screen improves the touch detection precision, and prevents the problems of visibility of edge images and light leakage of pixel electrodes near to the edge of the substrate.

Description
