    摘要： 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 5.5 to 22 degrees in an edge more parallel direction and a cube depth between about 0.0005 and 0.004 inches, or with a cant of about 8 to 35 degrees in a face more parallel direction and a cube depth between 0.001 and 0.012 inches.

    摘要： 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.

    摘要： A dual light-source position detecting system for use in touch screens is provided that utilizes parallax to determine the position of an interposing object, and a prismatic film that is brightly retroreflective over a broad entrance angle to enhance to accuracy of the parallax determination of position. The position detecting system includes at least one camera positioned to receive light radiation traversing a detection area and that generates a signal representative of an image; two spaced-apart sources of light radiation, which may be LEDs, or IR emitters positioned adjacent to the camera for outputting light radiation that overlaps over at least a portion of a detection area, and a prismatic film positioned along a periphery of at least a portion of the detection area that retroreflects the light radiation from the two sources to the camera. The prismatic film includes a plurality of triangular cube corner retroreflective elements having dihedral angle errors el7 e2, and e3 such that ex ~ e2 ≠ 0 and e3 ~ 0 to enhance the efficiency of the retroreflection of the light radiation from the two spaced apart LEDS or IR emitters along the sides of the detection area. If two cameras are mounted in opposing corners of a same side of the touch screen and two dual radiation sources are used in combination with these cameras, an unambiguous determination can be made of the location of two simultaneously interposing objects.
