Abstract
A moiré pattern display sheet is defined by a surface, with the surface being configured to be curved. A first layer has a pattern printed thereon. The pattern comprises a series of visual elements in a first row that have been distorted at least in a first direction. At least some of the series of visual elements are printed to approximately follow an arc having a sweep angle associated therewith. A light steering optical layer overlays the first layer. The light steering optical layer comprises a plurality of parallel optical features which each have a width and which change the direction of the light and thereby provide a depth effect of the visual elements to a viewer looking through the light steering optical layer.
Claims53
A moiré pattern display sheet defined by a surface, with the surface being configured to be curved, comprising:
- a first layer comprising a printed pattern, the pattern being divided into at least a first and second region, the pattern comprising a series of visual elements in a first row that have been distorted at least in a first direction, the series of visual elements of the first region being spaced apart by a first spacing and each of the series of visual elements of the first region having a first width, the series of visual elements of the second region being at least one of spaced apart by a second spacing different than the first spacing or the series of visual elements having a second width different than the first width;
- and
- a light steering optical layer overlaying the first layer, the light steering optical layer comprising a plurality of optical features which each have an optical element width and which change a direction of light passing through the optical layer,
- wherein the display sheet provides a depth effect of the visual elements to a viewer looking through the light steering optical layer.
A method of forming a moiré pattern display sheet defined by a surface, with the surface being configured to be curved, comprising:
- printing a first layer comprising a pattern printed, the pattern being divided into at least a first and second region, the pattern comprising a series of visual elements in a first row that have been distorted at least in a first direction, the series of visual elements of the first region being spaced apart by a first spacing and each of the series of visual elements of the first region having a first width, the series of visual elements of the second region being at least one of spaced apart by a second spacing different than the first spacing or the series of visual elements having a second width different than the first width;
- and
- providing a light steering optical layer to overlay the first layer, the light steering optical layer comprising a plurality of optical features which each have an optical element width and which change a direction of light passing through the optical layer,
- wherein the display sheet provides a depth effect of the visual elements to a viewer looking through the light steering optical layer.
A display sheet for displaying a moiré pattern on a curved surface, the display sheet comprising:
- a first layer comprising a printed pattern, the pattern comprising a series of distorted pattern elements in a first row, each distorted pattern element having a first dimension and a second dimension, at least some of the series of distorted pattern elements being printed to approximately follow an arc having a sweep angle associated therewith;
- and
- a light steering optical layer overlaying the first layer, the light steering optical layer comprising a plurality of optical features, each feature being configured to shift a direction of a path of travel of light passing through the feature,
- wherein the pattern is viewable through the light steering optical layer as a series of resultant pattern elements, each of the resultant pattern elements having a first resultant dimension, the first resultant dimension of the resultant pattern element being equal to the first dimension of the distorted pattern element multiplied by a constant factor, and
- wherein the display sheet provides a depth effect of the pattern to a viewer looking through the light steering optical layer.
