  • Publication number: 20170128336
    Abstract: The present disclosure relates to a method for inducing pluripotent stem cells by inducing reprogramming and/or dedifferentiation of differentiated adult cells using shikimic acid, a plant extract or plant stem cells containing shikimic acid and an extract of dedifferentiated stem cells (callus), pluripotent stem cells prepared by the method and a composition containing the pluripotent stem cells. In accordance with the present disclosure, ethical concerns implicated with the use of eggs to prepare pluripotent stem cells such as embryonic stem cell can be resolved. And, because the plant stem cell extract unharmful to human is used, pluripotent stem cells with proven safety can be prepared and they may be used to develop immunocompatible cell therapy agents suited for individuals. In addition, by pluripotent stem cells from individuals having diseases, the present disclosure will be very useful in studying the cause of diseases and devolving therapeutic strategy.

    Abstract: A method of displaying a stereoscopic image provides first light having a first wavelength and second light having a second wavelength different from the first wavelength to the a display panel according to left-eye and right-eye images displayed on the display panel. Color correcting data are generated by correcting at least one of left-eye color data corresponding to the left-eye image and right-eye color data corresponding to the right-eye image such that a first color coordinate according to the first light and a second color coordinate according to the second light coincide with each other with respect to the same color. The left-eye and right-eye images are displayed using light having wavelengths different from each other, so that a display quality of the stereoscopic image may be enhanced.

  • Patent number: 8395610
    Abstract: A driving chip includes a main input part, a plurality of circuit cells and an auxiliary input part. The main input part includes a plurality of input terminals which receive an external signal. The circuit cells generate a driving signal in response to a signal applied from the main input part. The auxiliary input part is spaced apart from the circuit cells by a first distance that is shorter than a second distance between the main input part and the auxiliary input part. The auxiliary input part receives the external signal and applies the external signal to the circuit cells. Therefore, line resistance variation between the circuit cells of the driving chip and a power input terminal may be decreased, so that driving chip defects may be prevented.
