Abstract:
A stereoscopic image display device includes a scan driver, a data driver, a light emission control driver, a display unit including a plurality of pixels, and a controller controlling the scan driver, the data driver, and the light emission control driver. The controller generates image data signals corresponding to a left-eye image display period, a right-eye image display period, and a black image display period during one frame and supplies the image data signals to the data driver. The black image display period, in which a black image according to the black data signal is displayed, and a shutter stabilization period, in which a left eye glass and a right eye glass of shutter spectacles are opened/closed, overlap each other between the left-eye image display period and the right-eye image display period.

Abstract:
The present invention relates to a zinc ferrite catalyst, a method of producing the same, and a method of preparing 1,3-butadiene using the same. Specifically, the present invention relates to a zinc ferrite catalyst which is produced in a pH-adjusted solution using a coprecipitation method, a method of producing the same, and a method of preparing 1,3-butadiene using the same, in which the 1,3-butadiene can be prepared directly using a C4 mixture including n-butene and n-butane through an oxidative dehydrogenation reaction. The present invention is advantageous in that 1,3-butadiene can be obtained at a high yield directly using a C4 fraction without performing an additional process for separating n-butene, as a reactant, from a C4 fraction containing impurities.
Abstract:
Disclosed is an arylphenoxy catalyst system for producing an ethylene homopolymer or copolymers of ethylene and α-olefins, and a method of producing an ethylene homopolymer or copolymers of ethylene and α-olefins having a high molecular weight under a high temperature solution polymerization condition using the same. The catalyst system includes a group 4 arylphenoxy-based transition metal catalyst and an aluminoxane cocatalyst or a boron compound cocatalyst. In the transition metal catalyst, a cyclopentadienyl derivative and arylphenoxide as fixed ligands are located around the group 4 transition metal, arylphenoxide is substituted with at least one aryl derivative and is located at the ortho position thereof, and the ligands are not crosslinked to each other. The catalyst includes non-toxic raw materials, synthesis of the catalyst is economical, and thermal stability of the catalyst is excellent. It is useful for producing an ethylene homopolymer or copolymers of ethylene and α-olefins having various physical properties in commercial polymerization processes.
Abstract:
A data transmission device may include a transmission chip, a plurality of reception chips and/or a pair of transmission lines. The transmission chip may transmit data and the reception chips may receive the data from the transmission chip. One of the plurality of reception chips may provide a corresponding terminal resistance when it receives the data. The transmission lines may be coupled between the transmission chip and the reception chips, and the transmission lines may have a daisy-chain configuration. Therefore, a data transmission device may provide a fixed terminal resistance in impedance matching and increase a transmission speed.
Abstract:
The prevent invention relates to a display apparatus having a display main body adapted to display a picture, a base part adapted to be mounted on an installation surface and supporting the display main body, and a stand part disposed between the base part and the display main body. A first hinge part is disposed between the display main body and the stand part to fold the stand part onto a rear of the display main body. A second hinge part is disposed between the stand part and the base part to rotate the base part between a supporting position where the base part is mounted in a substantially transverse direction with respect to the display main body and a folding position where the base part is mounted substantially parallel to a first end of the stand part. A locking assembly prevents and allows the base part from being and to be rotated between the supporting position and the folding position.
Abstract:
The present invention relates to Lactobacillus strain with a body-fat reducing activity and provides Lactobacillus rhamnosus Strain PL60 KCCM-10654P. The strain of the invention can be directly used as body-fat reducing functional foods, or can be used as additives of body-fat reducing functional foods or a ferment starter strain of body-fat reducing functional fermented foods. Body-fat inhibiting materials that the strain of the present invention produce can be isolated to be used. In addition, in case that fermented foods are produced using the strain the invention provides conditions capable of having a maximal body-fat reducing effect.
Abstract:
A DC-AC converter has two half-bridge circuits using an input feedback signal and an input clock signal together with time delay circuits, wherein one of the half-bridge circuits drives one pair of corresponding FETs and the other half-bridge circuit drives the other pair of corresponding FETs. The DC-AC converter includes: a Direct Current (DC) power source; a switching unit which includes a plurality of Field Effect Transistors (FETs) for changing paths of Direct Current (DC), so as to convert the DC to Alternating Current (AC); a transformer for transforming a voltage input from the switching unit; a load unit connected to the transformer; and a signal control unit for simultaneous parallel control of the FETs in the switching unit.
