Abstract

Disclosed is a wiring structure of an induction layer. The wiring structure of the induction layer comprises a plurality of first induction electrode units which are sequentially arranged in a first direction and a plurality of second induction electrode units which are sequentially arranged in a second direction, wherein the first direction is perpendicular to the second direction, the first induction electrode units are annular induction electrode units, and the second induction electrode units are linear induction electrode units. According to the wiring structure of the induction layer, by means of annular induction electrode units which are sequentially arranged in the second direction, the number of inductors is reduced, the scanning speed is improved, coupling capacitance with the linear induction electrode units is enlarged, and signal strength is improved.

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...
