Switchable light modulators, which may be films, including chambers filled with electro-optic media, such as electrophoretic media, wherein some chambers have a different volume of electro-optic media such that when the electro-optic media is switched between an “open” and “closed” state some regions of the light modulator having chambers of greater volume undergo a greater change in optical density than areas having chambers with smaller volumes. Such switchable light modulators are useful for incorporation into windshields, glasses, windows, lenses, or visors where it is desirable that only part of the viewing area is darkened. Because the design only requires two (typically light-transmissive) electrodes, operation is simplified and costs are reduced, as compared to individually-actuable pixel electrodes.

This application relates to a reflective display using color capsules and a method of manufacturing thereof. In one aspect, the method includes preparing a substrate in which first, second, and third receiving portions respectively having first, second, and third widths are formed by forming separating portions on a first substrate and forming the color capsules in which first, second, and third color capsules respectively having first, second, and third diameters are formed. The method may also include disposing the color capsule in which the first, second, and third color capsules are respectively inserted into the first, second, and third receiving portions, wherein the first, second, and third diameters respectively correspond to the first, second, and third widths. The color capsules are respectively inserted into receiving portions having the corresponding diameters, so that the reflective display which is convenient to manufacture and which has a multi-color pixel region may be provided.
