Abstract

A conformable, flexible or roll up display (100) includes a matrix display layer (115) including lines of sub-pixels (116). Each line has an associated color assigned to the line (132, 134, 136), and each line extends along a roll up or bend direction (140). A display effect layer (128) is formed on the matrix layer. A color filter layer (152) includes striped color filters (154) 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.
