    Abstract: The present invention relates to a driving method for cholesteric liquid crystal display. A plurality of pixels of the display are controlled by a plurality of row drivers and a plurality of column drivers. According to the method of the invention, firstly, a DC input voltage or a non-symmetric AC input voltage is applied to the row drivers and the column drivers so that the voltage of the pixel is larger than a withstand voltage of the drivers. Then, an initial column signal and an initial row signal are respectively supplied by the corresponding column driver and row driver so as to initialize the corresponding pixel. The polarity of the initial column signal is different from that of the initial row signal. Because the initial row signal minus the initial column signal equals the signal of the pixel, the amplitude of the signal applied to the pixel can be increased. Therefore, according to the invention, the initial time of the pixel can be decreased, and the transferring speed of the pixel can be improved.

    Abstract: This invention provides a method and computer-readable medium for detecting flesh-tone regions in pictures, images, and videos. First, a flesh-tone axis is defined in a color space coordinate system, the flesh-tone axis passing through both the center of a flesh-tone region and the origin of the color space coordinate system. A perpendicular point, is then calculated on the flesh-tone axis as being the point having the shortest distance to an input pixel. A first distance and a second distance are then calculated based on the coordinates of the input pixel, the perpendicular point and the center of the flesh-tone region. The determination as to whether the input pixel is in the flesh-tone region can be made based on the first distance and second distance.

    Abstract: An improved layout pattern for electrostatic discharge protection is disclosed. A first heavily doped region of a first type is formed in a well of said first type. A second heavily doped region of a second type is formed in a well of said second type. A battlement layout pattern of said first heavily doped region is formed along the boundary of said first heavily doped region and said second heavily doped region. A battlement layout pattern of said second heavily doped region is formed along the boundary of said first heavily doped region and said second heavily doped region. By adjusting a distance between the battlement layout pattern of a heavily doped region and a edge of well of said second type, i.e. n-well, a first distance will be shorter than what is typically required by the layout rules of internal circuit; and a second distance will be longer than the first distance to ensure that the I/O device have a better ESD protection capability. Accordingly, by properly adjusting the breakdown voltage of ESD device within I/O circuit, i.e. adjusting the distance between the edge of n-well and the battlement layout pattern of heavily doped regions, it will help to reduce the chip area and improve the ESD reliability.

    Abstract: A method for driving a fluorescent lamp and an inverter circuit for performing the same are used to reduce an amount of electromagnetic interference (EMI) generated by a transformer and an instantaneous loading of a DC voltage source. The inverter circuit comprises a DC square wave voltage source, a bridge DC/AC converter, a transformer, a feedback control unit and a voltage control circuit wherein the voltage control circuit is coupled to the DC voltage source, the bridge DC/AC converter and the feedback control unit. The voltage control circuit is used to convert DC voltage provided by the DC voltage source into a two-level DC square wave, which in turn converts the two-level DC square wave into an AC quasi-sine wave to drive the fluorescent lamp through the bridge DC/AC converter and the transformer. The feedback control unit generates signals to control the voltage control circuit and the bridge DC/AC converter.
