    • A individually formed EL module device, named herein as a nixel, adapted to be integrated into a modular electroluminescent display (ELD), is presented. The nixel of the present invention can be in the form of a subpixel, a pixel, or a plurality thereof. The nixel can be made in a variety of shapes, and can be individually tested and sorted according to its mechanical and/or electrical attributes prior to being integrated into an ELD. A customized ELD can be made by selecting nixels of particular characteristics in accordance with ELD application and/or user specifications. Nixels can easily be arranged to form a variety of color patterns on an ELD. A nixel can include a lower electrode layer, a ceramic base layer, a first charge injection layer, a phosphor layer, a second charge injection layer and an upper electrode layer. Nixels can be positioned on a flexible display structure to produce a flexible and scalable ELD.
    • 本发明提供一种单独形成的EL模块装置,这里被称为元件,适于集成到模块化电致发光显示器(ELD)中。 本发明的像素可以是子像素,像素或其多个的形式。 该元件可以制成各种形状,并且可以在被集成到ELD之前,根据其机械和/或电气属性进行单独测试和分类。 可以通过根据ELD应用和/或用户规格选择具有特定特征的元素来定制ELD。 可以轻松地排列消光器,以在ELD上形成各种颜色图案。 元件可以包括下电极层,陶瓷基层,第一电荷注入层,磷光体层,第二电荷注入层和上电极层。 Nixel可以放置在灵活的显示结构上,以产生灵活且可扩展的ELD。

    • An electroactive device incorporating the invention is configured from an electroactive ceramic hollow sphere having an inner surface, an outer surface, a wall thickness aspect and a radius aspect. Conductive electrodes are positioned on opposed surfaces of said sphere and conductors enable application of an electrical potential between the conductive electrodes to enable a field to be applied to said sphere that causes a dimension change in the radius aspect and thickness aspect thereof. In one embodiment the sphere has a d33 direction parallel to the thickness aspect, and d31 & d32 directions parallel to the sphere surfaces and in another embodiment the d33 direction is perpendicular to the thickness aspect, and d31 & d32 directions are respectively parallel and perpendicular to the sphere surfaces. The sphere is preferably supported by a rod that either passes throng one opening in the sphere or through two opposed openings. Further, the rod may include a pathway for other instrumentality's. Arrays of such devices are also disclosed.
