Covers for touch-sensing devices include a shielding layer; and a substrate, in which the substrate covers the shielding layer, and the substrate and the shielding layer are integrated and form a coplanar surface. The coplanar surface is a smooth surface, which has a surface roughness Ra in a range from about 0.05 &#x3bc;m to about 0.5 &#x3bc;m.

Touch-sensing cover and manufacturing method thereof

The present disclosure discloses a device having multiple printing layers and a printing method thereof, wherein said method comprises: seriatim stack-printing at least one printing layer on a protective substrate in an ascending order of size, wherein the protective substrate has an open surface exposed outward and a laminating surface laminated with a plate, and wherein the printing layer is printed on a part of the laminating surface and the closer the printing layer is to the laminating surface, the smaller area the printing layer has so as to reduce height difference between printing layers and make for the following lamination.

Device having multiple printing layers and a printing method thereof

The present disclosure related to circuit structure of an electronic device, wherein the circuit structure comprises of a main line formed on a substrate; and at least an auxiliary line electrically connected to the main line to form a conductive return circuit used for a signal to pass through the auxiliary line when the main line is disconnected. Addition of the auxiliary line avoids any breaking of signal transmission due to partial disconnection of the main line. The present disclosure also relates to a method for manufacturing the circuit structure, wherein the method simplifies the manufacturing process and also reduces the rate of deformation or disconnection of lines.
