  • Patent number: 7719504
    Abstract: A liquid crystal display and a driving method thereof. A gate driver drives a first pixel of the display via a first scanning line within a frame period including first and second data writing intervals. A first data voltage and a second data voltage are transmitted to the first pixel in the first and second data writing intervals, respectively. After the first data writing interval, a first color light source illuminates the first pixel. After the second data writing interval, a second color light source illuminates the first pixel. In a reset interval between the first and second data writing intervals, a voltage of a common line coupled to a storage capacitor of the first pixel is changed from a first common voltage to a second common voltage so that a voltage of a first liquid crystal capacitor of the first pixel is changed.

  • Publication number: 20090101202
    Abstract: A method of improving efficiency of solar cells made of crystalline silicon, including monocrystalline silicon, multicrystalline silicon and polycrystalline silicon is provided. In the method, a negative bias pulse is applied to solar cells at a predetermined voltage, a predetermined frequency, and a predetermined pulse width while immersing the solar cells in a hydrogen plasma. Hydrogen ions are attracted and quickly implanted into the solar cells. Thus, the passivation of crystal defects in the solar cells can be realized in a short period. Meanwhile, the properties of an antireflection layer cannot be damaged as proper operating parameters are used. Consequently, the serious resistance of the solar cells can be significantly reduced and the filling factor increases as a result. Further, the short-circuit current and the open-circuit voltage can be increased. Therefore, the efficiency can be enhanced.
