Color filter to prevent color errors in a roll up display

Abstract

A conformable, flexible or roll up display includes a matrix display layer including lines of sub-pixels. Each line has an associated color assigned to the line, and each line extends along a roll up or bend direction. A display effect layer is formed on the matrix layer. A color filter layer includes striped color filters which extend in the roll up or bend direction. The striped color filters each include a filter color corresponding with the lines of sub-pixels in the matrix layer to address misalignment and color errors due to bending or rolling up the display. Methods for fabricating flexible displays are also disclosed.

1 - 26 . (canceled) 
     
     
         27 . A flexible, rollable or conformable display, comprising:
 a matrix display layer including lines of sub-pixels, each line having an associated color assigned to the line, each line extending along a roll up or bend direction;   a display effect layer formed on the matrix layer;   a color filter layer including striped color filters which extend in the roll up or bend direction, the striped color filters each include a filter color corresponding with the lines of sub-pixels in the matrix layer to address misalignment and color errors due to bending or rolling up the display; and   a fixing material applied at an end portion of the display to couple and fix the display effect layer to the color filter layer.   
     
     
         28 . The display as recited in  claim 27 , wherein the striped color filters are manufactured separately from the display and are attached to the display by an adhesive. 
     
     
         29 . The display as recited in  claim 27 , wherein the striped color filters are formed by deposition and patterning using photolithography. 
     
     
         30 . The display as recited in  claim 27 , further comprising a spool configured to roll up the display. 
     
     
         31 . The display as recited in  claim 27 , wherein the fixing material includes a stripe applied perpendicularly to the roll up or bend direction at an end portion of the color filter layer. 
     
     
         32 . The display as recited in  claim 27 , wherein the fixing material includes a plurality of spots applied at end portions of the color filter layer. 
     
     
         33 . A flexible, rollable or conformable display, comprising:
 a matrix display layer including lines of sub-pixels, each line having an associated color assigned to the line, each line extending along a roll up or bend direction, the lines being arranged to include a single color component;   a display effect layer formed on the matrix layer;   a color filter layer formed on the display effect layer and including striped color filters, each striped color filter being associated with the single color component of a corresponding line of sub-pixels and the striped color filter formed to cover the line of sub-pixels, the striped color filters extending in the roll up or bend direction to address misalignment and color errors due to bending or rolling up the display; and   a fixing material applied at an end portion of the display to couple and fix the display effect layer to the color filter layer.   
     
     
         34 . The display as recited in  claim 33 , further comprising a spool configured to roll up the display. 
     
     
         35 . The display as recited in  claim 33 , wherein the fixing material includes a stripe applied perpendicularly to the roll up or bend direction at an end portion of the color filter layer. 
     
     
         36 . The display as recited in  claim 33 , wherein the fixing material includes a plurality of spots applied at end portions of the color filter layer. 
     
     
         37 . A method for fabricating a flexible display device, comprising:
 forming a matrix layer having sub-pixels arranged in lines such that each sub-pixel in a line provides illumination for a given color component;   forming a display effect layer on the matrix layer; and   on the display effect layer, forming color filter stripes longitudinally in a roll up or bend direction, each stripe corresponding to and covering a line of sub-pixels to reduce misalignment and color errors due to bending; and   securing the color filter stripes with a fixing material applied at an end portion of the display.   
     
     
         38 . The method as recited in  claim 37 , wherein forming color filter stripes includes depositing and patterning the color filter stripes using photolithography. 
     
     
         39 . The method as recited in  claim 37 , wherein forming the color filter stripes includes ink jet printing the color filter stripes. 
     
     
         40 . The method as recited in  claim 37 , wherein forming the color filter stripes includes silk screening/shadow masking to form the color filter stripes. 
     
     
         41 . The method as recited in  claim 37 , wherein forming the color filter stripes includes manufacturing the color filter stripes separately from the display and attaching the color filter stripes to the display by an adhesive. 
     
     
         42 . The method as recited in  claim 37 , wherein the fixing material includes a stripe applied perpendicularly to the roll up direction at an end portion of the color filter stripes. 
     
     
         43 . The method as recited in  claim 37 , wherein the fixing material includes a plurality of spots applied at end portions of the color filter stripes.
