Abstract: The invention relates to a reset device for a scan driver. The scan driver is used for driving a control circuit of a display. The reset device comprises: a first input terminal, a second input terminal and a reset circuit. The first input terminal receives a first input voltage. After the first input voltage inputs to the first input terminal, the second input terminal receives a second input voltage. The second input voltage has a temporary section and a stable section. At the stable section, the second input voltage is larger than the first input voltage. When the first input terminal receives the first input voltage, the reset circuit outputs a reset signal to the scan driver. When the second input voltage is larger than a threshold value at the temporary section, the reset circuit clears the reset signal. According to the reset device of the invention, the scan driver maintains at a reset state so as to prevent that outputs of the scan driver to be at high level at the same time of supplying power. Therefore, the reset device can lower the malfunction of the control circuit and decrease the probability of damage and breakdown to maintain normal operation and life of the control circuit can be maintained.

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.
