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: The present invention relates to a color filter with mosaic pixel array arrangement. The color filter comprises a plurality of pixel arrays. The pixel array has four sub-pixels. The color of the sub-pixel of the pixel array is identical to that of another sub-pixel of another pixel array adjacent to the pixel array. The sub-pixels with same color form a sub-pixel group so that the area of a single color of the sub-pixel group is increased. Therefore, the adhesion strength between the sub-pixel group and the substrate can be augmented to avoid peeling from the substrate. According to the invention, the yield rate of the product will be raised and the chromaticity will be improved.

Abstract: The present invention relates to an illumination device of an LCD projection system. The illumination device comprises a light source, a quarter-wave retardation and a wire grid polarizer. The light source is used for providing light. The quarter-wave retardation is disposed near the light source. The wire grid polarizer is disposed parallel to the quarter-wave retardation, and is associated with the quarter-wave retardation to polarize the light from the light source. P-polarized light can pass through the wire grid polarizer. S-polarized light cannot pass through the wire grid polarizer, and is reflected to the quarter-wave retardation to become circular polarized light. The circular polarized light is reflected by a parabolic surface of the light source and passes through the quarter-wave retardation again to convert into p-polarized light. The converted p-polarized light can pass through the wire grid polarizer. Therefore, the illumination device of the invention can provide high-efficiency polarized light. The illumination device can achieve high polarization conversion efficiency, and can be manufactured easily to reduce costs.

Abstract: The driving circuit of a liquid crystal cell structure consists essentially of first and second write-enable transistors, first and second storage capacitors, first and second display-enable transistors, and a reset/preset transistor. When one of the display-enable transistors is turned on such that the video data saved in the corresponding storage capacitor is loaded into the mirror electrode for display, the other corresponding write-enable transistor is turned on simultaneously to pre-load the next video data into the corresponding storage capacitor. When the first and second display-enable transistors both are turned off, the reset/preset transistor is turned on to set the liquid crystal in the reset/preset voltage, wherein the reset/preset voltage is based on the overdrive voltage of the arrangement of the liquid crystal before next sub-frame time so as to increase the response rate of the liquid crystal cell.
