    • A display panel driving apparatus supplies pixel driving potentials corresponding to pixel data to the source lines of a display panel. The pixels are located at the intersections of the source lines and a set of scanning lines. For each pixel, the driving potentials are alternately positive and negative with respect to a common reference potential supplied to the display panel. While the display driving apparatus is latching the pixel data for the pixels on each scanning line, the output circuits of the display driving apparatus are disconnected from the source lines, allowing the source lines to return to the common reference potential, thereby avoiding unwanted current flows in the output circuits and unwanted distortion of the pixel driving waveforms.
    • 显示面板驱动装置将对应于像素数据的像素驱动电位提供给显示面板的源极线。 像素位于源极线和一组扫描线的交点处。 对于每个像素,相对于提供给显示面板的公共参考电位,驱动电位交替地为正和负。 当显示驱动装置锁存每个扫描线上的像素的像素数据时,显示驱动装置的输出电路与源极线断开,从而允许源极线返回到公共参考电位,从而避免不必要的电流流动 在输出电路和像素驱动波形的不期望的失真。

    • A display panel driving circuit includes an input part for amplifying an input on-off signal so as to generate a first on-off voltage signal, a voltage signal generation part for generating a second on-off voltage signal which is varied in response to variations of the first on-off voltage signal, and an output part generating a push-pull output voltage as a driving voltage so as to drive a display panel in response to the first and second on-off voltages. The display panel driving circuit further includes a controlling part for controlling the voltage signal generation part so that a difference between on and off voltages of the second on-off voltage signal is not smaller than a predetermined voltage. Therefore, the push-pull output voltage whose response speed is well balanced when the push-pull output voltage increases and decreases can be generated without increasing electric power consumption and a circuit area.

    • The acoustic signal transmission method is based on generating a synthesized sound electrical signal by electrically synthesizing an audible sound signal and another signal different than the audible sound signal at the sending side, and transmitting the synthesized sound electrical signal, and extracting the another signal different than the audible sound signal from the synthesized sound electrical signal at the receiving side. Here, generation of the synthesized sound electrical signal is made by using a data hiding technique, for example. Accordingly, the acoustic signal represented by the synthesized sound electrical signal can be heard by human ears in the same way as the audible sound signal, and the synthesized another signal cannot be detected by human ears. Here, the synthesized sound electrical signal can be transmitted as a sound wave in air space, as electrical signal through a transmission line or as radio signals such as infrared and electromagnetic waves. It is also possible to transport or distribute the synthesized sounds by recording on recording media such as compact disc and DVD. Also, using the signal extracted from the synthesized sound electrical signal, applications such as controlling machines such as robot, transmitting text data such as information for car navigation systems, computer network addresses and commercial business information.
