Color filter to prevent color errors in a roll up display
View Patent ↗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.
1. A flexible, rollable or conformable display, comprising:
a matrix display layer with a spool applied at an end of the matrix display layer, the 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 which is perpendicular to a longitudinal axis of the spool;
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 the display effect layer to the color filter layer, 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.
2. The display as recited in claim 1 , wherein the striped color filters are manufactured separately from the display and are attached to the display by an adhesive.
3. The display as recited in claim 1 , wherein the striped color filters are formed by deposition and patterning using photolithography.
4. A flexible, rollable or conformable display, comprising:
a matrix display layer with a spool disposed at an end of the matrix display layer, the 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 which is perpendicular to a longitudinal axis of the spool, 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 the display effect layer to the color filter layer, 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.
5. A flexible, rollable or conformable display, comprising:
a matrix display layer with a spool applied at an end of the matrix display layer, the 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 which is perpendicular to a longitudinal axis of the spool;
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 the display effect layer to the color filter layer, wherein the fixing material includes a plurality of spots applied at end portions of the color filter layer.
6. The display as recited in claim 5 , wherein the striped color filters are manufactured separately from the display and are attached to the display by an adhesive.
7. The display as recited in claim 5 , wherein the striped color filters are formed by deposition and patterning using photolithography.
8. A flexible, rollable or conformable display, comprising:
a matrix display layer with a spool disposed at an end of the matrix display layer, the 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 which is perpendicular to a longitudinal axis of the spool, 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 the display effect layer to the color filter layer, wherein the fixing material includes a plurality of spots applied at end portions of the color filter layer.
9. The display as recited in claim 8 , wherein the striped color filters are manufactured separately from the display and are attached to the display by an adhesive.
10. The display as recited in claim 8 , wherein the striped color filters are formed by deposition and patterning using photolithography.
