    Abstract: Disclosed is a display comprising an arrangement of a plurality of optically anisotropic rotatable elements, each of the rotatable elements having a surface in contact with an enabling fluid, the rotatable elements being electrically dipolar in the presence of the enabling fluid and thus being subject to rotation upon application of an electric field, the rotatable elements being free to rotate in place but not free to translate substantially so as to disrupt the arrangement of rotatable elements, wherein a first portion of the surface contains a mixture of a chelating agent and a spiropyran material of the formula 1 wherein n is an integer representing the number of repeat nullCH2null units and R is nullH or nullCHnullCH2, and wherein a second portion of the surface contains substantially no spiropyran.

    Abstract translation: 公开了一种显示器，其包括多个光学各向异性可旋转元件的布置，每个可旋转元件具有与启用流体接触的表面，可旋转元件在有效流体存在的情况下是电偶极性的，因此被旋转 在施加电场时，可旋转元件可自由旋转到位，但不能自由平移以便基本上平移以便破坏可旋转元件的布置，其中表面的第一部分包含螯合剂和螺吡喃材料的混合物 其中n是表示重复-CH 2 - 单元的数目的整数，R是-H或-CH = CH 2，并且其中表面的第二部分基本上不含螺吡喃。
