Abstract:
A light-emitting substrate includes a substrate, a plurality of light-emitting members arranged in a matrix on the substrate, and a plurality of metal backs arranged in a matrix over the plurality of light-emitting members. In each row or each column of the plurality of metal backs, two adjacent metal backs are connected to each other through a resistive member. A conductive member having a resistance value lower than that of the resistive member is connected to a portion of the resistive member, the portion being spaced from the two adjacent metal backs.

Abstract:
The electroluminescent (EL) element comprises a transparent plastic film substrate (1) onto whose rear side a transparent first electrode layer (2) comprised of indium tin oxide (ITO) is vacuum sputtered. A first electroluminescent layer (3) with dispersed electroluminophores (4) is placed on the first electrode layer (2). This first electroluminescent layer consists of a transparent matrix (5) into which the electroluminophores (4) are incorporated (4). The second electrode layer (rear electrode layer) (6) is placed on the first electroluminescent layer (3) or on an insulating intermediate layer (not shown) located thereon. This second electrode layer is insulated toward its side facing away from the first electroluminescent layer (3) by means of the insulating layer (7). On the front side, i.e. the visible face, a third electrode layer (8) comprised of transparent conductive lacquer is applied to the plastic film substrate (1). A second electroluminescent layer (9) with dispersed electroluminophores (4) is placed on the third electrode layer (8). The fourth electrode layer (10) comprised of transparent conductive lacquer is placed on said second electroluminescent layer (9) or on an insulating intermediate layer (not shown) located thereon. This fourth electrode layer (10) is insulated on the visible face by means of an insulating layer (11).
Abstract:
One pixel is divided into a first region including a first light emitting element and a second region including a second light emitting element, wherein the first region emits light in one direction and the second region emits light in the direction opposite to that of the first region. Independently driving the first light emitting element and the second light emitting element allows images to be displayed independently on the surface.
Abstract:
A method of constructing a flexible panel display using gold as a conductive element and a matrix of carbon fibers as emitters is presented. The invention provides a novel defined pixel width of three emitter fibers per cell wherein each cell is positioned within three emulsion layers of suspended nano-crystals stack positioned vertically atop one-another. Each of these respective layers is excited by a single carbon fiber. In the preferred embodiment, fiber length ends from each cell are positioned at the mid-point of each respective polymer layer thickness and produce one of red, green, or blue colors required to complete the image formation.
Abstract:
The present invention relates to a field-emission display having a faceplate formed with a phosphor layer and means irradiating an electron beam onto the phosphor layer in order to improve the characteristic of life of the device. The feature of the present invention is in the structure of a phosphor layer. The phosphor layer is expressed by a general formula: ZnS: M, Al where M is an activator of at least one of Cu, Ag and Au; and Al is a coactivator, in which the concentration of Al is higher than that of M. According to the present invention, the electrification characteristic of the phosphor is improved for lower resistance. The defect concentration of the surface of the phosphor is reduced. The filed-emission display which can realize improvement in the characteristic of life which has not been solved in the prior art can be made.
