Problems solved by technology

Traditional touch sensors, whether they are plug-in or Oncell / Incell integrated into the display, are usually made of transparent conductive film (ITO), and ITO is a brittle semiconductor material. The action is prone to breakage problems, so there is a risk of poor function
Traditional touch electrode patterns, whether it is a mutual capacitive touch sensor or a self-capacitive touch sensor, have a risk of fracture at the edge of the electrode pattern due to stress concentration

Abstract

A touch sensor includes: a sensing electrode including a plurality of independent sub-sensing electrodes arranged in an array; and an induction electrode lead wire, which is arrange on that same layeras the induction electrode and arranged at a gap position between two adjacent sub-induction electrodes, wherein one end of the induction electrode lead wire is correspondingly connected with a sub-induction electrode, and the opposite end is used for connected with a processing circuit for extracting a touch signal sensed by the sub-induction electrode. At least a portion of the edge of the sub-sensing electrode comprises a convex portion or a concave portion of a curve, and the convex portion and the concave portion of two adjacent sub-sensing electrodes are disposed opposite to each otherin complementary relation; and the lead wires of the inductive electrode are arranged along the gap between two adjacent sub-inductive electrodes in a curve. Therefore, the risk of rupture of the inductive electrode and its leads during bending are effectively reduced.

Description

technical field [0001] The invention relates to the technical field of touch display screens, in particular to a touch sensor. Background technique [0002] Flexible AMOLED has good bending and flexibility, so it is required that the touch sensor matched with it should also have good flexibility. Traditional touch sensors, whether they are plug-in or Oncell / Incell integrated into the display, are usually made of transparent conductive film (ITO), and ITO is a brittle semiconductor material. The role of the easy to break the problem, so there is a risk of poor function. For traditional touch electrode patterns, whether it is a mutual capacitance touch sensor or a self-capacitance touch sensor, the edge of the electrode pattern is likely to be broken due to the concentration of stress. [0003] Therefore, it is necessary to provide a touch sensor to solve the problems in the prior art. Contents of the invention [0004] The invention provides a touch sensor without comple...
