Imprinted micro-louver structure

Abstract

A micro-louver structure includes a cured layer on a surface. A plurality of micro-channels forms a pattern in the cured layer. The micro-channels have a greater depth than width and are spaced apart by a separation distance greater than the width. A cured light-absorbing material is located in the micro-channels.

         9 . The micro-louver structure of  claim 1 , wherein the width of the imprinted micro-channels is less than or equal to four microns, two microns, or one micron. 
     
     
         10 . The micro-louver structure of  claim 1 , wherein a cross-section of the imprinted micro-channels in a plane parallel to the surface of the cured layer substantially forms an array of lines in one direction. 
     
     
         11 . The micro-louver structure of  claim 1 , wherein a cross-section of the imprinted micro-channels in a plane parallel to the surface of the cured layer substantially forms a grid with lines extending in two different directions. 
     
     
         12 . The micro-louver structure of  claim 1 , wherein a cross-section of the imprinted micro-channels in a plane parallel to the surface of the cured layer substantially forms one or more polygons or circles. 
     
     
         13 . The micro-louver structure of  claim 1 , further including a substrate having the surface and wherein the substrate is a component of a display. 
     
     
         14 . The micro-louver structure of  claim 13 , wherein the substrate is a display cover or display substrate. 
     
     
         15 . The micro-louver structure of  claim 1 , further including two cured layers located together in a spatial relationship. 
     
     
         16 . The micro-louver structure of  claim 15 , wherein the micro-channels of the two cured layers are spatially in phase or spatially 180 degrees out of phase. 
     
     
         17 . The micro-louver structure of  claim 15 , further including a substrate having opposed surfaces and wherein the two cured layers are located on opposing surfaces of the substrate. 
     
     
         18 . The micro-louver structure of  claim 15 , further including a substrate having a surface and wherein a first one of the cured layers is located on the surface of the substrate and a second one of the cured layers is located on the first one of the cured layers. 
     
     
         19 . The micro-louver structure of  claim 15 , further including a substrate having the surface on which at least one of the cured layers is formed and wherein the substrate is a component of a display. 
     
     
         20 . A micro-structure for use with a display which permits orthogonal display viewing while inhibiting display viewing at larger angles, comprising:
 a cured layer on a surface;   a plurality of imprinted micro-channels forming a pattern in the cured layer, wherein the imprinted micro-channels have a greater depth than width and are spaced apart by a separation distance greater than the width;   a cured light-absorbing material in the imprinted micro-channels; and   wherein the micro-structure is located on a viewing surface of the display, whereby orthogonal display viewing is enabled while display viewing at larger angles is inhibited.
