The present disclosure provides a method to provide a conductive bus bar on a patterned transparent conductor, such as ITO traces used for touch screen manufacturing. The method can be a cheaper and a more convenient technique to pattern a conductive metal or metal alloy, such as copper, silver, or a copper/silver/titanium alloy, on ITO electrodes in a roll-to-roll process.

Method of patterning a metal on a transparent conductor

A device including a transparent or semitransparent substrate and at least one layered structure disposed on a first major surface of the substrate is described. The layered structure includes a first ITO layer on the substrate, a silicon dioxide layer on the first ITO layer opposite the substrate, and a second ITO layer on the silicon dioxide layer opposite the first ITO layer. The silicon dioxide layer includes an edge that is offset inwardly from an edge of the first ITO layer and from an edge of the second ITO layer. Methods of making the device are described.

Conductive layered structure and methods of making same

A reflection sheet and a method of manufacturing a reflection sheet are disclosed. The reflection sheet comprises a substrate layer and a reflective layer formed on the substrate layer, wherein the reflective layer comprises an alloy consisting of silver (Ag), palladium (Pd) and neodymium (Nd).

Reflection sheet and method of manufacturing the same

Provided is a touch panel comprising: a transparent substrate, a transparent conductive material disposed on the 5 substrate, and a Ag&#x2014;Pd&#x2014;Nd alloy layer disposed on the transparent conductive material. Provided are also a preparation method of the touch panel and a display comprising the touch panel. Provided are also a Ag&#x2014;Pd&#x2014;Nd alloy for touch panel, comprising: 97.9 to 99.2 weight % of Ag, 0.7 to 1.8 weight % of Pd, and 0.1 to 0.3 weight % of Nd, based on 100 weight % of the alloy.

Touch panel, preparing method thereof, and Ag&#x2014;Pd&#x2014;Nd alloy for touch panel

The invention relates to a method for patterning one or more portions of a microstructure comprised of a flexible substrate, a conductor disposed on the substrate, and a metal layer disposed on the conductor, wherein the conductor is comprised of a stack of a first and a second transparent conductive oxide (TCO) layer, and a metal doped silicon oxide layer sandwiched between the two TCO layers.

Method for patterning a microstructure

A capacitive touch screen sensoris disclosed. The sensorcomprises an array of drive electrodes, an array of sense electrodesseparated from the array of drive electrodes by a dielectric layer, each sense electrodebeing offset from each drive electrodeto define respective overlapping regionsand first non-overlapping regions, and a plurality of non-electrically connected electrodes, each non-electrically connected electrodebeing arranged to correspond to each first non-overlapping regionand spaced from adjacent driveor sense electrodesby a perimeter gap. The perimeter gapmay have a width of about 100 um or less. A related touch panel and method of fabricating the same are also disclosed.

Capacitive touch screen sensor and corresponding method of fabrication

In one embodiment a transparent conductive component is described comprising a flexible transparent substrate; a transparent conductive layer disposed on the flexible transparent substrate; and a plurality of metal traces disposed on and in electrical communication with the transparent conductive layer. A portion of the flexible transparent substrate comprising the transparent conductive layer and metal traces forms an interconnect circuit tab. At least the interconnect circuit tab comprises a cured organic polymeric material disposed on the (e.g. patterned) transparent conductive layer and metal traces metal traces and flexible transparent substrate such that the cured organic polymeric material forms an exposed surface layer. The cured organic polymeric material is optionally disposed at the bezel region and/or at a central region of the transparent conductive component (e.g. touch sensor).

Transparent conductive component with interconnect circuit tab comprising cured organic polymeric material

An article includes a multilayer structure, such as, e.g., a touch sensor, having two opposing sides and comprising a central polymeric UV transparent substrate, a transparent conductive layer on each of the two major opposing surfaces of the polymeric substrate, a metallic conductive layer on each transparent conductive layer, and a patterned photoimaging mask on each metallic conductive layer.

Flexible touch sensor with fine pitch interconnect

A double ITO structure, containing sequential layers of indium tin oxide (ITO), silicon dioxide (SiO) (which may include a dopant material) and ITO, is selectively protected by a patterned photo-resist mask. The sequential layers are etched together in a single etching step using an etchant composition which is an acidic solution containing a transition metal chloride and hydrochloric acid (HCl). Thus, the double ITO structure is etched using a substantially fluoride-free etchant composition.
