Title:
SINGLE SIDED DOUBLE LAYER MULTI-TOUCH SCREEN
Document Type and Number:
WIPO Patent Application WO/2018/018753
Kind Code:
A1
Abstract:
A single sided double layer multi-touch screen, relating to the technical field of touch screens. The multi-touch screen comprises: a cover plate (10), an adhesive layer (20), and a conductive layer having a bridging function that are sequentially provided. The conductive layer comprises a first insulating layer (30), a conductive silver adhesive layer (40), a second insulating layer (50), and a conductive indium-tin oxide layer (60) that are sequentially provided. The conductive indium-tin oxide layer (60) comprises a flexible transparent substrate (611), an indium-tin oxide coating layer (612), and a plurality of drive electrodes (613) and sensing electrodes (614). Insulating through holes (511) are formed on the second insulating layer (50). The conductive silver adhesive layer (40) comprises a conductive bridging wire (412) and a conductive metal wire (411), the conductive bridging wire (412) being used for connecting adjacent drive electrodes (613) to each other via the insulating through holes (511). In the provided touch screen, the drive electrodes (613) can be connected by means of the conductive bridging wire (412), thereby reducing the number of terminals used for the connection between the drive electrodes (613) and an external FPC, increasing the width of traces, and improving the touch precision and the product yield; in addition, the two insulating layers can achieve a good insulating effect.
