Embodiment Construction

[0019] The present invention provides embodiments of flexible or roll-up displays that include improved alignment between subpixels and color filters to improve display viewing quality.

[0020] It should be understood that the elements shown in the figures can be implemented in a variety of configurations. For purposes of illustration, these embodiments will be described with respect to the type of electrophoretic display that includes a polymer substrate that allows for the formation of a conformable, flexible, or roll-up display. Other types of displays can also benefit from the teachings in this invention. For example, liquid crystal displays, electroluminescence displays, etc. may also benefit from the teachings of the present invention.

[0021] Referring to the drawings, in which like numerals indicate like or similar elements, Fig. 3 shows a conformable, flexible or roll-up display 100 according to the principles of one embodiment. The display effect layer 128 includ...

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.

Description

technical field [0001] The present disclosure relates to flexible displays, and more particularly to devices and methods for forming color filters on these devices. Background technique [0002] Flat panel displays include color filters to remove certain color components in the light illumination from the subpixels of such displays. An extrinsic display includes a display effect layer that reflects or emits broad-spectrum (white) light and a color filter layer that changes white light into colored light. The display effect layer and color filter layer need to be properly aligned to avoid parallax problems or aperture problems. When making conformable, flexible or even rollable displays in this way, alignment problems can arise between the display effect layer and the color filter layer because the radii of these layers differ during bending or rolling. [0003] Referring to FIG. 1 , a rollable display 10 is shown to illustrate the alignment between pixel structures 22 in a...
