Abstract

Provided is a wiring structure of an induction layer. The induction layer comprises first induction electrodes and second induction electrodes, wherein the first induction electrodes and the second induction electrodes are arranged in stagger, the first induction electrodes are in longitudinal connection, and the second induction electrodes are in transverse connection. The first induction electrodes and the second induction electrodes are respectively provided with main bodies in the same shape, the main bodies extend to form branch bodies, a gap is reserved between adjacent branch bodies, the branch bodies of the first induction electrodes are inserted in gaps of the second induction electrodes, and the branch bodies of the second induction electrodes are inserted in gaps of the first induction electrodes. The main bodies of the wiring structure extend to from a plurality of branch bodies to enable capacitive coupling and signal sensitivity between the electrodes to be better, the suspension problem can be better solved, and distinguishable fingerweb distance can be reduced. In addition, the first induction electrodes and the second induction electrodes adopt the main bodies in the same shape, so that design is flexible, and adaptability on hardware structure is strong.

Description

technical field [0001] The invention relates to a wiring structure of a sensing layer of a touch screen, in particular to a wiring structure of a sensing layer of a capacitive touch screen. Background technique [0002] With the development of science and technology, touch screens have gradually replaced mechanical button panels as new operating interfaces for electronic devices such as mobile phones and notebooks. Touch screens include resistive touch screens, infrared touch screens, and capacitive touch screens. They obtain coordinates in different ways, and capacitive touch screens are used in more and more products because of their better light transmittance, clarity, and reliability. . [0003] An important part of the capacitive touch screen is the sensing layer. The commonly used capacitive touch screen sensing layer includes X-axis sensing electrodes and Y-axis sensing electrodes. The rows are arranged in several columns, and one column of X-axis sensing electrodes...
