  • Publication number: 20180108296
    Abstract: A pixel compensation circuit is arranged for compensating the critical parameter associated with the electrical properties of the components in thin film transistors of an active matrix organic light emitting diode display or similar illumination systems to avoid uneven brightness resulted from the voltage drop effect. The pixel compensation circuit is defined in a sub-pixel area, wherein there are eight thin film transistors and one capacitor, and the circuit is operated by two control signals. In contrast, three control signals are required in the conventional technologies. The fewer control signals are required, which is benefit to the flexibility of the layout and design of specification.

  • Publication number: 20180096732
    Abstract: The present invention discloses a high stability shift register with adjustable pulse width to be achieved by a circuit structure through purely N-type transistors or purely P-type transistors. The structure comprises eight thin film transistors and a capacitor, and uses the 8T1C structure as a repeating unit. The invention can obtain an output signal from an input signal, two DC signals and two AC signals. The AC signal is a two line-time frequency pulse wherein the pulse width is smaller or equal to the line-time. The output signal will shift a line-time on the time axis with the input signal, and as an input signal to the next shift register in sequence. Compared with the conventional technique, the invention reduces the amount of the components to obtain a high stability and adjustable pulse width shift register.

  • Publication number: 20160355495
    Abstract: An organocatalytic kinetic resolution of racemic secondary nitroallylic alcohols via Michael/acetalization sequence to give fully substituted tetrahydropyranols is described. The process affords the products with high to excellent stereoselectivities. The highly enantioenriched, less reactive (S)-nitroallylic alcohols were isolated with good to high chemical yields. The synthetic application of the resolved substrate is shown toward the synthesis of enantioenriched (+)-(2S,3R)-3-amino-2-hydroxy-4-phenylbutyric acid.

  • Patent number: 7094472
    Abstract: The invention relates to ethylene polymers that are modified by ionizing radiation, prior to article formation, at a temperature less than the crystalline melt temperature and preferably under ambient atmosphere, as well as articles made from said polymers. The irradiated ethylene polymers exhibit enhanced melt strength, tensile strength, impact resistance, tear strength, adhesion to polar substances and thermal stability, decreased elongation, and lower melt flow index, but are easily processed and converted into and onto articles by conventional technologies including injection molding, extrusion, film and bottle blowing and powder coating.

  • Publication number: 20060054801
    Abstract: The present invention discloses a biochip scanning device including a light source for emitting a light; a rotatable optical grating hologram located at one side of the light source for diffracting the light to form a diffractive light; a sampling stage that can be placed a specimen and can be irradiated with the diffractive light; and a linear charge coupled device (CCD) that can receive a reflective light of the diffractive light via the specimen. With the rotatable optical grating hologram, the light can be uniformly diffracted, and a more correct signal noise ratio is obtained to ensure accuracy of the light signal. In addition, the light can be replaced by a linear light source to effectively improve the scan speed and save the testing time.

  • Publication number: 20050147776
    Abstract: A bottle container provided with a protective layer is provided by coating a protective layer composed of a nanoscale titanium dioxide (TiO2) and copper particle on the surface of a bottle container, characterized in that, when sunlight irradiates over the bottle container, UV light or visible light of shorter wavelength (=about 600 nm and less), they will be absorbed therein and generates subsequently electrons and electric holes to react water and oxygen in air into active oxygen and hydroxyl free radical as strong oxidants. These oxidants can decompose surrounding organic matters and can kill bacteria as well as de-odor. In case of thus coated bottle container containing beer, UV light or strong light cannot enter substantially into the beer contained therein to oxidize hop components in the beer, and consequently, the intact taste of the beer can be retained.
