摘要:
The present invention comprises an organic light emitting device comprising a first electrode, a second electrode, and an organic stack interposed between the first electrode and the second electrode, wherein the organic stack further comprises at least one organic layer, wherein the organic layer further comprises organic compounds such that the organic light emitting device continues to function in temperatures in excess of 145 DEG C. The organic layer may be comprised of organic compounds with tetrahedral shaped core structures, tetrahedral shaped core structures containing aromatic side groups, tetrahedral shaped core structures containing aromatic amine side groups, symmetrical tetrahedral shaped core structures, symmetrical tetrahedral shaped core structures containing aromatic side groups, and/or symmetrical tetrahedral shaped core structures containing aromatic amine side groups.

Electrophoretic displays include a light-emitting layer, a photoconductive layer, and an electrophoretic layer. The light-emitting layer may be an organic, light-emitting material, or organic, light-emitting diode, which is addressable using a multiplex addressing drive scheme. The impedance of the photoconductive layer is lowered when struck by light from the light-emitting layer. As a result of the lowered impedance of the photoconductive layer, the electrophoretic layer, which itself cannot be multiplexed, is addressed at a lower, subthreshold voltage.

Novel addressing schemes for controlling electronically addressable displays include a scheme for rear-addressing displays, which allows for in-plane switching of the display material. Other schemes include a rear-addressing scheme which uses a retroreflecting surface to enable greater viewing angle and contrast. Another scheme includes an electrode structure that facilitates manufacture and control of a color display. Another electrode structure facilitates addressing a display using an electrostatic stylus. Methods of using the disclosed electrode structures are also disclosed. Another scheme includes devices combining display materials with silicon transistor addressing structures.

摘要:
An organic electroluminescent element comprising a dimeric stryryl compound represented by general formula (I) as the luminescent material, wherein D, D', E, E', F, F', G, G' and Q are each as defined in the specification. The dimeric styryl compound used is one prepared by bonding two molecules of a compound having a good luminescence efficiency and a desirable luminescence wavelength to each other via a divalent group which breaks a conjugated system without impairing the abilities of the compound to thereby increase the molecular weight (to dimerize) and improve the properties as thin film. Therefore this element is widely applicable as various display materials.

Film aggregate having electricity conducting characteristics. The film is comprised of a substantially inert support surface carrying one or several monomolecular film layers formed by a surface active material of liquid crystal type having modifiable electrical properties. The film layer is of a sandwich type construction containing at least the folllowing zones: - a spacer-zone (2) containing aliphatic hydrocarbyl groups and which to its electrical characteristics is substantially inert, - a conducting area (3-5) which on the one hand is comprised of a charge-transfer zone (3 or 5) and on the otherhand of a polarizable zone (5 or 3) as well as of a spacer zone (4) between these zones, - a spacer zone (6) which corresponds to the above zone (2), - a hydrophilic zone (7). The invention concerns also new glycerophospholipids and threitolphospholipids to be used in the films, containing in their fatty side chains at least one, but preferably two active groups, i.e. a polarizable group and charge-transfer group. The invention also concerns the fatty acids, alcohols group and amines used for the side chains in the lipids and carrying a polarizable group and a charge-transfer group.
