Abstract

A single-layer wiring capacitive 2D touch sensor comprises a substrate and a conductive layer attached on the substrate. The conductive layer comprises several sensing electrode slabs and several driving electrode slabs. The sensing electrode slabs and the driving electrode slabs are arranged alternately, and a gap having an equal interval exists between adjacent sensing electrode slabs and driving electrode slabs. The driving electrode slab comprises a first driving electrode slab and a second driving electrode slab, both the first driving electrode slab and the second driving electrode slab have a toothed edge, and the toothed edges of the both mesh with each other. The first driving electrode slabs in the driving electrode slabs are short circuited to form a driving electrode channel; the second driving electrode slabs in the driving electrode slabs are short circuited to form another driving electrode channel. By adopting the capacitive touch screen wiring manner, wiring can be simplified and resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of capacitive touch screens, in particular to a capacitive two-dimensional touch sensor with single-layer wiring. Background technique [0002] Capacitive touch sensors have gradually replaced resistive touch sensors due to their flexible touch and support for multi-touch, and they have a great advantage in the market. Traditional capacitive touch screens are usually implemented by multi-layer wiring. Although there are currently only single-layer ITO implementations, jumpers need to be added at the intersections of the driving electrodes and the sensing electrodes. The design of adding jumpers In the production process, it is first necessary to lay an insulating layer at the cross position, and then lay jumpers on the insulating layer. The increase of jumpers will make the overall wiring complex and dense, and increase the production process. process, and will affect the aesthetics of the wiring. Therefor...
