  • Publication number: 20190036546
    Abstract: A storage device includes a nonvolatile memory device and a controller configured to read data from the nonvolatile memory device, to divide the read data into a plurality of segments, and to sequentially perform error correction decoding with respect to the plurality of segments. When the error correction decoding of each segment is completed, the controller adds error correction parity to each of the decoded segments and sends the decoded segments with added error correction parity to an external host device. When error correction decoding of a second segment is not completed after a threshold time has elapsed after sending a first segment of which error correction decoding is completed, the controller adds an incorrect error correction parity to dummy data and sends the dummy data with the added incorrect error correction parity to the external host device.

  • Patent number: 8779561
    Abstract: Disclosed herein is a Light Emitting Diode (LED) backlight unit without a Printed Circuit board (PCB). The LED backlight unit includes a chassis, insulating resin layer, and one or more light source modules. The insulating resin layer is formed on the chassis. The circuit patterns are formed on the insulating resin layer. The light source modules are mounted on the insulating resin layer and are electrically connected to the circuit patterns. The insulating resin layer has a thickness of 200 ?m or less, and is formed by laminating solid film insulating resin on the chassis or by applying liquid insulating resin to the chassis using a molding method employing spin coating or blade coating. Furthermore, the circuit patterns are formed by filling the engraved circuit patterns of the insulating resin layer with metal material.

  • Patent number: 7446922
    Abstract: Disclosed herein is an interdigitation-type diffractive light modulator. In the interdigitation-type diffractive light modulator of the present invention, each of a pair of ribbons has a plurality of diffractive branches which are arranged in a comb shape, and the diffractive branches of the ribbons interdigitate with each other. Furthermore, the respective ribbons moves upwards and downwards or, alternatively, one ribbon moves upwards and downwards, so that the diffractive branches of the ribbons which interdigitate with each other form a stepped structure, thus diffracting incident light.
