摘要:
An organic light emitting device and a method of manufacturing the same, the organic light emitting device includes a first electrode, a second electrode, and an organic layer that has at least a multi-coated emissive layer and which is interposed between the first and second electrodes. The multi-coated emissive layer is a single layer composed of a neutral emissive material and an no−ne parameter of the emissive layer is greater than an no−ne parameter of a single-coated layer. The organic light emitting device has a longer lifetime and high efficiency.
摘要:
A spirofluorene-based polymer which contains a spirofluorene structure as a basic unit and which is end-capped with functional moieties substituted by fluorine, and an organic electroluminescent device using an organic layer using the spirofluorene-based polymer. The organic electroluminescent device has improved efficiency, reduced driving voltage, and excellent thermal, optical and electrical stability.

摘要:
An organic thin film transistor (OTFT) comprising a gate electrode, a gate insulating film, an organic active layer and a source/drain electrode, or a gate electrode, a gate insulating film, a source/drain electrode and an organic active layer, sequentially formed on a substrate, wherein the gate insulating film is a multi-layered insulator comprising a first layer of a high dielectric material and a second layer of an insulating organic polymer compatible with the organic active layer, the second layer being positioned directly under the organic active layer. The OTFT of the present invention shows low threshold and driving voltages, high charge mobility, and high Ion/Ioff, and it can be prepared by a wet process.
摘要:
A reciprocating compressor includes: a cylinder installed inside a casing and having a space therein; a piston disposed inside the cylinder; an inner stator fixed at an outer circumference of the cylinder; a magnet fixed at an outer circumference of the inner stator; and an outer stator disposed to maintain a certain distance from an outer circumference of the magnet. Accordingly, the number of components is reduced thus to reduce a manufacturing cost, and performance can be also improved.
摘要:
The present invention is related to embankment block, which preventing deviation. More particularly, the present invention provides advertisement effect combined use with revetment block by planting various kinds of vegetation in order to represent literary expression, symbolic words, and advertisement copy. The characteristics of the present invention include mutual connecting method, that is, the side joining of inserting projection and groove, galvanized steel wire connecting through the wire hole that is perforated to main body and the side surface of block. The main body of block is shot through from above to below.
