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.

An SRAM device is disclosed, which comprises a plurality of rows of SRAM cells and a line-buffer SRAM cell. Each row of SRAM cells is controlled by a word line. The line-buffer SRAM cell is coupled to the rows of SRAM cells and controlled by a read enable line. The signal on the read enable line is activated after the signal on the word line is activated, and part of the activated signal on the read enable line overlaps with the activated signal on the word line. The power provided to the line-buffer SRAM cell is selectively cut off.

A video image conversion method is for converting interlaced image into progressive image. The deinterlacing method for the video system is for converting the interlaced image into the progressive image. The method performs an interpolation algorithm based on the pixel value of a reference field. An inter-field estimation on the pixel values is performed by referring to a predetermined value to calculate difference value between specific vicinity pixel value and predetermined value, to obtain a set of pixel values, corresponding to the minimum value of summation of a set of pixel difference values. The pixel value corresponding to the auxiliary field is interpolated. The reference field and the auxiliary filed are also referred as the odd field and the even field, where neither the interlacing order nor the respective correspondence is constrained. The method further detects a still motion, such that the flickering is effectively eliminated in another interpolation mode.

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.
