Abstract
An appearance-modifying device for modifying the visual appearance of a surface covered thereby, the device comprising a first substrate, a second substrate, a spacer structure spacing apart the first and second substrates in such a way that a space between the first and second-substrates is divided into a plurality of cells wherein in each cell, an optically transparent fluid having a plurality of particles is dispersed therein, wherein each of the cells is configured such that a distribution state of the particles is controllable in a first distribution state and an appearance of the surface covered by the appearance-modifying device is determined by optical properties of the particles and a second distribution state in which the particles are concentrated onto one of a first particle concentration site and a second particle concentration site.
