Electrophoretic display modules including various types of backplane and edge seals for protecting electro-optic displays against environmental contaminants are described. In particular, the disclosed module designs allow for very narrow edge seals, i.e., less than 1 mm in thickness. In one type of seal, the electro-optic layer is sandwiched between a backplane and a protective sheet and a sealing material extends between the backplane and the protective sheet. In some instances, the protective sheet includes several layers of transparent materials to provide physical protection and reduce the ingress of water.

Electrophoretic display with low profile edge seal

Systems and methods are disclosed for pressure-sensitive, electrophoretic displays, which may optionally include haptic feedback. A display may comprise a first conductive layer having a pressure-sensitive conductivity and an electrophoretic layer positioned adjacent to the first conductive layer, wherein the electrophoretic layer is in electrical communication with the first conductive layer and is configured to locally change state based on a pressure applied to the first conductive layer. Local and global writing and erasing of the display can also be achieved.

Pressure-sensitive writing media comprising electrophoretic materials

An apparatus for a three-dimensional display is disclosed that includes a waveguide having a pair of opposed faces configured to propagate radiation along a length of the waveguide between the faces, a radiation source optically coupled to the waveguide and configured to transmit the radiation to the waveguide, at least one prismatic element having a face optically coupled to at least one of the faces of the waveguide, and a layer of image modulating material optically coupled to at least one of the faces of the waveguide. The image modulating material may be optically coupled to an area of at least one of the faces of the waveguide, at least a portion of the area being located outside a perimeter of a face of the prismatic element optically coupled to at least one of the faces of the waveguide. The image modulating material may also be optically coupled to at least one of the faces of the waveguide, such that the waveguide is between the layer of image modulating material and the at least one prismatic element.
