    Abstract: A single thrust bearing fluid dynamic bearing (FDB) design, including a typical dynamic bearing design which comprises a ring-shaped or circular thrust plate mounted at or near the end of a shaft, wherein the shaft defines together with the surrounding sleeve a journal bearing by providing grooves on one of the two surfaces facing the gap between the shaft and the sleeve. On the thrust plate, only one of the two surfaces is grooved to establish an active thrust bearing. The rotor is then biased against the single active thrust bearing with a constant force generated by a magnetic circuit.

    Abstract: A flexible display device has one or more flexible electrode assemblies. Each of the electrode assemblies includes a hierarchical control arrangement for selectively activating electrodes of the display device. The hierarchical control arrangement includes high-level control elements and low-level control elements, each of the high-level control elements being operatively coupled to respective subsets of the low-level control elements, which in turn are coupled to respective groups of the electrodes. Exemplary control elements are microstructure elements containing imbedded microprocessors or integrated circuits. The use of a hierarchical control arrangement results in data signals having to pass through fewer control elements when compared with single-level arrangements. This increases operation speed and reduces power losses due to voltage drops across control elements. In addition, the number of connections to device(s) external to the display may thereby be reduced.

    Abstract: An electroluminescent display device includes a transparent substrate and an electroluminescent element disposed over the substrate. The electroluminescent element has a first electrode disposed over the substrate, a second electrode disposed over the first electrode and a light emitting layer disposed between the first and second electrodes. The display device also includes a thin film transistor driving the electroluminescent element, and a protection film disposed over the second electrode and being configured to prevent a penetration of moisture into the electroluminescent element. The second electrode is formed by evaporating aluminum so that the light emitting layer receives no damage, and the protection film is deposited by sputtering to provide a film with a high relative density so that moisture is prevented from entering the electroluminescent element.

    Abstract: A method to ensure uniform deposition of organic layer is disclosed. Since the organic layer is very thin, any deviation from the target thickness will result in visible optical defects. A homogenous layer which exhibits good coating behaviour with organic materials is provided beneath the organic layer. By covering the metal interconnects, the adverse effect on the uniformity of the polymer layer is reduced or prevented.

    Abstract: In a light emitting diode, a scattering material-containing light guiding/scattering layer is provided which directly receives light emitted from a light emitting element. The scattering material contained in the light guiding/scattering layer irregularly reflects and scatters the incident light. The scattered light is led to a fluorescence emitting layer formed of a transparent binder containing a phosphor material. The probability of incidence of light having high optical density, which has been emitted from the light emitting element, directly to the phosphor material contained in the fluorescence emitting layer is lowered, and light can be radiated from the whole fluorescence emitting layer. Therefore, uniform light having a desired color can be radiated with high efficiency from the light emitting diode.
