Patent number: 8928625Abstract: A touch screen system and prismatic film includes a retroreflective substrate having a plurality of retroreflective elements having triangular cube corners. A metallized layer is disposed over at least a portion of the retroreflective elements. In one embodiment, the prismatic film includes two colored substrates mounted over the retroreflective elements. In another embodiment, a single substrate is mounted over the retroreflective elements. It is often desired that a color of the substrate(s) be chosen that is highly transparent in the infrared spectrum, but is also non-transparent in the visible light spectrum, giving the prismatic film a dark appearance. The prismatic film includes a plurality of retroreflective elements having triangular cube corners with a cant in a range between about 4 degrees in a face more parallel direction to 18 degrees in an edge more parallel direction and a cube depth between about 0.002 and 0.008 inches or with a cant of about 5.Type: GrantFiled: January 12, 2009Date of Patent: January 6, 2015Assignee: Avery Dennison CorporationInventors: Steven R. Chapman, Simon Bridger

Patent number: 8783880Abstract: A rotationally insensitive, retroreflective prismatic sheeting and method of manufacture is provided. The sheeting includes discrete clusters of cube corners that are separated from one another on all sides by a textured surface. Each of the cube corners in each cluster has a base edge that is not collinear or parallel with the base edges of cube corners on either side of it. The array of cube corners clusters is rulable, and the cube corners have different orientations. Four or more of the cube corners in each cluster may have edges that converge into a central point within the cluster, and the cube corners of the clusters may include at least two symmetrical pairs of cube corners. The shapes of the cube corner clusters may be polygonal, and all of the cube corners may share a common vertex located at the center of the polygonal shape.Type: GrantFiled: November 1, 2011Date of Patent: July 22, 2014Assignee: Avery Dennison CorporationInventors: Steven R.

Publication number: 20140055858Abstract: A retroreflective article and method is provided. The retroreflective article includes a first transparent layer having a back surface with retroreflective prisms, and a planar front surface that has an index of refraction n1. A second transparent layer having an index of refraction n2 is less than n1 overlies the back surface of the first layer. The second layer includes an array of uniform nanostructures of transparent material that define pores having a width that is less than one half of the wavelength of visible light. The nanostructures may be an array of parallel, same-sized nanorods that are obliquely oriented with respect to the first transparent layer, or a grid-like or parallel array of tapered nano-ridges of uniform size that define tapered pores or tapered grooves. The second layer preferably has a porosity greater than 60% so that the resulting index of refraction n1 is no larger than about 1.20.Type: ApplicationFiled: August 27, 2012Publication date: February 27, 2014Applicant: AVERY DENNISON CORPORATIONInventor: Steven R.

Publication number: 20110255306Abstract: Various embodiments comprise light recycling films comprising an array of parallel ridges and grooves that form prisms that selectively reflect or transmit light. In some embodiments, the light recycling film may be used in displays that include spatial light modulators comprising a plurality of pixels. The light recycling film can limit the field-of-view of the display and enhance the luminance within that field-of-view. Various embodiments comprising multiple arrays of ridges and/or grooves can enhance uniformity of illumination of the pixels in the spatial light modulator and reduce Moiré effects.Type: ApplicationFiled: January 4, 2011Publication date: October 20, 2011Applicant: AVERY DENNISON CORPORATIONInventors: Dennis I.
