Abstract: A nozzle plate and printhead allowing for control of a deflection direction of ejected droplets using electro-wetting, and methods of operating and manufacturing the same. The nozzle plate has at least one nozzle for ejecting fluid and includes electrode segments disposed along a circumference of the nozzle, an insulating layer disposed on a surface of each electrode segment so as to contact fluid in the nozzle, the insulating layer divided into at least two insulating layer segments corresponding to the electrode segments, and a wire pattern electrically coupled to the electrode segments.

Abstract: An inkjet printhead having a cantilever actuator, the inkjet printhead including a plurality of ink chambers containing ink to be ejected; a manifold containing ink to be supplied to the plurality of ink chambers; a plurality of restrictors supplying ink to the plurality of ink chambers from the manifold; a plurality of nozzles ejecting ink from the plurality of ink chambers; and a plurality of cantilever actuators each installed in each of the plurality of ink chambers and having one fixed end and the other deflectable end, such that pressure for ejection of ink is applied due to the deflection of the other end of the cantilever actuator to the ink inside the ink chamber. The cantilever actuator may be made of a bimorph element, eject ink through the nozzle from the ink chamber, and also prevent backflow of ink from the ink chamber to the restrictor by virtue of the deflection of the other end thereof.

Abstract: An organic light emitting device can includes first and second metal layers used as electrodes on a substrate, an electron transport layer on the first metal layer, a first partition wall insulating the first metal layer from the second metal layer and extending onto the electron transport layer along the first metal layer, a second partition wall on the first metal layer around the electron transport layer, a third partition wall separated from the first partition wall and on the second metal layer, an organic light emitting layer on the electron transport layer, a hole transport layer on the organic light emitting layer and contacting the second metal layer, a protecting layer covering the hole transport layer and extending to the first and second metal layers beyond the second and third partition walls, and sealing materials filling spaces between the protecting layer and the first and second layers.

Abstract: A plasma display panel (PDP) and a method of manufacturing the panel includes sustain electrodes having a double gap structure and a predetermined resistance value. Each of the sustain electrodes includes a main electrode for sustaining a discharge and an auxiliary electrode for starting a low-voltage discharge without decreasing efficiency. A gap between auxiliary electrodes included in different sustain electrodes, respectively, is narrower than a gap between the different sustain electrodes. Each auxiliary electrode is formed between barrier ribs or immediately above a barrier rib. A ditch is formed in a dielectric layer covering the main electrodes and the auxiliary electrodes. The ditch is formed immediately above an auxiliary electrode.

Abstract: The present invention provides a method for improving blood compatibility of interpenetrating multicomponent polymer by controlling various factors affecting phase separation such as composition ratio, synthetic temperature, synthetic pressure, cross-linking density and hydrophilicity of polyurethane in the course of synthesizing interpenetrating polymer network ("IPN") where hydrophilic urethane resin and hydrophobic styrene derivative are cross-linked each other. IPN materials of the invention may be widely used in various applications such as artificial organ or surface finishing material which are in direct contact with blood, since they inhibit thrombogenesis by suppressing platelet adhesion and agglutination.
