摘要： DDR_SDRAM chips running at 1.5 clock rate are used for transferring image data from an image data source to a source driver in a display panel. In general, P DDR_SDRAM chips running at a 1.5 clock rate are used to store frame data in N frames. If the frame date in each of the N frames is n bits and the memory space in the DDR_SDRAM chip is m, then P is a smallest integer equal to or greater than N multiplied by (n/m). In data transfer in a frame, a line period is partitioned into N segments and each DDR-SDRAM chip is separated into (N−1) parts such that the parts are used to read different data in the different frames. In order to share I/O pins when using a number of DDR_SDRAM chips, the read/write sequence for the all DDR_SDRAM chips follows the same command and address.

摘要： A method for driving a liquid crystal display includes: a) receiving a video signal from a first group of gray scales values; b) comparing a current frame of the video signal with a previous frame to determine whether the current frame is in a static state or in a dynamic state; c) when the current frame is determined to be in the static state, converting the video signal to a driving signal; d) when the current frame is determined to be in the dynamic state, calculating a overdrive signal. The value of the driving signal is selected from a second group of gray scale values having at least one decimal point gray scale and having the same number of gray scale values as that of the first group of gray scale values. The value of the overdrive signal is selected from the first group of gray scale values.

摘要： A LCD (Liquid Crystal Display) with improved motion image quality and a driving method therefor. The LCD includes a pixel, a data driving circuit and a scan driving circuit. The data driving circuit generates over driving pixel data and gray pixel data according to pixel data of a Nth frame and pixel data of a (N+1)th frame, and outputs driving voltages, which correspond to the over driving pixel data, black pixel data and the gray pixel data, to the pixel at first, second and third time. The scan driving circuit outputs a scan signal at the first time, second time and third time to enable the pixel to receive the driving voltages corresponding to the over driving pixel data, the black pixel data and the gray pixel data. The driving voltages enables the pixel to generate a brightness curve similar to a pulse curve.
