摘要： A database system includes a master server, a pair of slave servers and a main storage carrier. Each slave server is provided with a database management system (DBMS). The main storage carrier and the pair of slave servers uses the ISCSI protocol to make the pair of slave servers serving as the DBMS and the main storage carrier serving as a database (DB) connect and communicate to further make the DBMS and the DB independent and separate. The master server performs service assignment to the pair of slave servers according to a predetermined weight value. All connections of the database are directed to the slave server with a high weight value, and the other slave server with a low weight value serves as a standby.

摘要： 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.

摘要翻译： 本发明涉及胆甾型液晶显示器的驱动方法。 显示器的多个像素由多个行驱动器和多个列驱动器控制。 根据本发明的方法，首先，对行驱动器和列驱动器施加DC输入电压或非对称AC输入电压，使得像素的电压大于驱动器的耐受电压。 然后，相应的列驱动器和行驱动器分别提供初始列信号和初始行信号，以初始化对应的像素。 初始列信号的极性与初始行信号的极性不同。 由于初始行信号减去初始列信号等于像素的信号，所以可以增加施加到像素的信号的幅度。 因此，根据本发明，可以减少像素的初始时间，并且可以提高像素的传送速度。
