Abstract: A touch panel includes a touch sensor having a dielectric core layer disposed between first and second piezoelectric layers. Each piezoelectric layer comprises a poled piezoelectric polymer. The touch sensor further includes at least a first set of individually addressable electrodes disposed over the first piezoelectric layer and at least one second electrode disposed over the second piezoelectric layer. Circuitry is coupled to the first set of electrodes and the second electrode. The circuitry is configured to detect a change in an electrical signal of at least one electrode of the first set of electrodes referenced to the second electrode in response to a touch applied to the touch surface of the touch sensor.

Abstract: A film includes a first layer having a substantially constant thickness. The first layer extends substantially uniformly along a length direction of the first layer and includes adjacent continuous first and second portions extending along the length direction. Each of the first and second portions includes a substantially constant thickness portion extending to an edge of the first layer along a width direction of the first layer, and a tapering portion adjacent the substantially constant thickness portion and having a thickness tapering in the width direction to a minimum thickness at an end of the tapering portion opposite the substantially constant thickness portion. The minimum thickness can be less than 20% of a thickness of the substantially constant thickness portion. The tapering portions of the first and second portions can have respective first and second major surfaces substantially conforming to one another.

Abstract: The present disclosure provides an article including a layer having a nanostructured first surface including nanofeatures and an opposing second surface, and an organic layer including a major surface attached to a portion of the nanofeatures. The nanostructured first surface includes protruding features that are formed of a single composition and/or recessed features. The nanofeatures and the major surface of the second layer together define at least one void. The present disclosure also provides a method of making the article including contacting nanofeatures of a layer having a nanostructured surface with a major surface of an organic layer and reacting at least one material to secure the two layers together. In addition, the present disclosure provides an optical information display and an OLED device including the article. The nanostructured surface of the article is protected from damage and contamination by the organic layer.

Abstract: Substrates suitable for use in a touch sensor are described. In some cases, the substrates include an inner layer and first and second heat-set polymeric outer layers. The first and second outer layers each have an in-plane birefringence of less than 0.1. The inner layer is substantially uniaxially birefringent and has an in-plane birefringence greater than 0.01. In some cases, a substrate includes a block copolymer which includes a first polyester and second polyester. The first polyester has a melting point greater than 200 ° C., and the second polyester having a melting point less than 200° C. The block copolymer includes the second polyester at 50 to 80 percent by weight. The substrate is substantially uniaxially birefringent and has an in-plane birefringence between 0.001 and 0.1.

Abstract: An integral multilayer optical film includes a plurality of interference layers; a structured layer disposed on the interference layers and including a plurality of particles dispersed in a binder; and a barrier layer disposed between the structured layer and the interference layers and co-extruded with the interference layers and the structured layer. The structured layer has a first major surface facing away from the interference layers and a second major surface facing the interference layers. The barrier layer causes the particles to impart a greater surface roughness to the first major surface than the second major surface so that when the optical film is illuminated with a light source, the optical film has a first average effective transmission T1 when the first major surface faces the light source and a second average effective transmission T2 when the first major surface faces away from the light source, where T1-T2≥5%.

Abstract: This disclosure describes multilayer polymer films that are configured so that successive constituent layer packets may be delaminated in continuous sheet forms from the remaining film. This disclosure further describes compositions, materials, and methods for minimizing the likelihood of removing multiple layer packets together including by increasing the peel force between layer packets. In some embodiments, that the peel force becomes successively greater from the interface between the first layer packet and the second layer packet to the interface between the next to last ((n−1)th layer packet) and the last (nth layer packet).
