  • Publication number: 20170326231
    Abstract: The present invention relates to an epitope specific to hepatitis B virus surface antigen and a binding molecule binding to the same for neutralizing hepatitis B virus. Since the epitope provided by the present invention is produced by forming a three-dimensional structure and does not comprise a determinant, by which escape mutation is induced against an administration of existing vaccines or HBIg, a composition comprising an antibody biding to the epitope or a vaccine composition comprising the epitope has a very low possibility of causing a decrease in efficacy due to escape mutation. Therefore, such an antibody or vaccine composition can be very effectively used in prevention and/or treatment of HBV.

  • Patent number: 9812066
    Abstract: An organic light emitting display includes a plurality of pixel row groups, a scan driver, a data driver, and a data distributor. Each pixel group includes the same number of pixel rows, and the pixel row groups are sequentially driven. The data distributor demultiplexes data signals for input into the pixels. The data signals are input to the pixels after threshold voltage compensation is performed at substantially a same time for pixels in each of the pixel row groups. Data signals are to be input to pixels in one pixel row group while threshold voltage compensation is performed for pixels in another pixel row group adjacent to the one pixel row group.

  • Patent number: 9626893
    Abstract: An organic light emitting display device includes a driver to drive at least one pixel. The driver drives the pixel based on a frame which includes at least one data sub-frame and at least one hysteresis reset sub-frame. The driver applies an emission data voltage or a non-emission data voltage to the pixel during the data sub-frame, and applies a reset voltage to reset a driving transistor of the pixel during the hysteresis reset sub-frame. The reset voltage may initialize a voltage-current characteristic of the driving transistor during the hysteresis sub-frame.
