A cholesteric liquid crystal writing board display device includes a plurality of cholesteric liquid crystal writing tablets and a front cover layer extending over the cholesteric liquid crystal writing tablets. The cholesteric liquid crystal writing tablets are tiled together by the front cover layer such that the writing board display device appears nearly seamless. Or, the writing tablets can be spaced apart from each other.

Cholesteric writing board display device

An electronic display comprises an electro-optic layer comprising electro-optical material. The display includes a first electrically conductive layer and a second electrically conductive layer, the electro-optic layer being disposed between the first electrically conductive layer and the second electrically conductive layer. A first substrate is disposed adjacent the first electrically conductive layer and a second substrate is disposed adjacent the second electrically conductive layer. The first substrate and the second substrate are formed in a shape that has at least one outer peripheral edge boundary, excluding any ledges. Internal ledges are disposed inside the at least one outer peripheral edge boundary. A first of the internal ledges comprises a portion of the first substrate and an exposed portion of the first electrically conductive layer and a second of the internal ledges comprises a portion of the second substrate and an exposed portion of the second electrically conductive layer.

Electronic display with internal ledges

A method of making an electrooptical display comprises providing a first substrate and a second substrate. A first layer of electrically conductive material is disposed on the first substrate and a second layer of electrically conductive material is disposed on the second substrate. A bead of adhesive gasket material is formed over the first substrate. Light modulating material is flowed onto the first layer of electrically conductive material and over the bead. The second substrate is positioned in contact with the light modulating material in proximity to the first substrate. The gasket material is cured.
