Embodiment Construction

[0020] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0021] The invention discloses a single-layer multi-touch functional sheet, such as figure 1 As shown, it includes a plurality of electrode groups 1 arranged in parallel from top to bottom. The electrode group 1 includes a plurality of electrodes 2, and the electrodes 2 are provided with wires 3, forming a gap between two adjacent electrode groups 1. There is a wiring area, and the wiring area is used to lead out the wires 3 of the electrodes 2 above it, and the wires 3 of two adjacent electrode groups 1 are led out in opposite directions, and the area of ​​the plurality of electrodes 2 in the electrode group 1 is along the The lead-out directions of the wires 3 decrease successively.

[0022] Compared with the prior art, the present invention better saves the wiring space between the sensing electrodes, reduces the requirements for the product...

Abstract

A functional single-layer multi-point touch sheet, comprising a plurality of layers of electrode groups (1) provided in parallel from top to bottom, the electrode group (1) comprising a plurality of electrodes (2), the electrodes (2) being provided with wires (3), a wiring zone being formed between two adjacent electrode groups (1) for guiding the wires (3) of the upper electrodes (2) out of the wiring zone, the wires (3) of two adjacent electrode groups (1) being guided out in opposite directions, the areas of the plurality of electrodes (2) in the electrode group (1) being sequentially reduced in the guiding direction of the wires (3). As a result, the invention saves wiring space between sensing electrodes, reduces the requirements of production processes, reduces blind touch zones effectively, improves precision, and meanwhile can realize multi-point touches.

Description

technical field [0001] The invention relates to a capacitive touch screen, in particular to a single-layer multi-touch functional sheet and a method for acquiring touch coordinates. Background technique [0002] At present, capacitive touch screens, as an important part of human-computer interaction, have been widely used in electronic products. Among them, the touch screen with a single layer of sensing electrodes has attracted widespread attention due to its low manufacturing cost, and has become an important development direction of the capacitive touch screen. [0003] The mutual-capacitance screen touch screen adopting the double-layer electrode design scheme is widely used because of its relatively good touch accuracy. However, compared with a touch screen using a single-layer electrode scheme, a touch screen using double-layer electrodes has higher material costs and more complicated processing procedures, so the total manufacturing cost is relatively high. Although...
