TOUCH SENSOR, TOUCH DISPLAY SCREEN, AND ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/043271

Kind Code:

A1

Abstract:

A touch sensor (13), a touch display screen, and an electronic device. The touch sensor (13) comprises: a substrate, a bridge electrode line, and an electrode layer formed on the substrate. The electrode layer comprises at least a first electrode pattern (131). The first electrode pattern (131) comprises a plurality of first conductive units (1311) spaced apart from each other. A boundary line (1312) of the first conductive unit (1311) comprises a curved connecting section (1313). The connecting section (1313) comprises at least one first concave/convex portion (1314). First concave/convex portions (1314) are sequentially connected to form a smooth curve. The bridge electrode line (132) extends in a curve, and both ends thereof separately span the connecting section of two adjacent first conductive units (1311), and electrically connect the two first conductive units (1311). The bridge electrode line (132) comprises at least one second concave/convex portion (1321). Second concave/convex portions (1321) are sequentially connected to form a smooth curve. The touch sensor (13) improves the bending resistance of a touch electrode.
