    摘要: In one embodiment of the present invention, an active-matrix type display unit, and a drive method thereof are disclosed. Gate-bus lines are provided at both top and bottom sides of each row. Two sub-pixels are formed at a region surrounded by two adjacent source-bus lines and two adjacent gate-bus lines. At the odd-numbered rows, for the left-side sub-pixel of those two sub-pixels, a scanning signal is supplied from the top-side gate-bus line, while a video signal is supplied from the left-side source-bus line. For the right-side sub-pixel, on the contrary, a scanning signal is supplied from the bottom-side gate-bus line, while a video signal is supplied from the right-side source-bus line. At the even-numbered rows, the gate-bus line from which a scanning signal is supplied is reversed to the case of the odd-numbered rows. The gate-bus lines are sequentially selected one by one, and all the video signal polarities are made the same during each horizontal scanning period.

    摘要: In one embodiment of the present invention, the liquid crystal display device of the invention performs an overshoot drive, including: an LCD having a liquid crystal panel for displaying video image; a frame memory installed outside of the LCD; and lookup table, the table with which third gray scale data most suitable for performing the overshoot drive to the LCD can be computed based on first gray scale data of a first frame and second gray scale data of a second frame, where the second frame is a frame right before the first frame and is stored in the frame memory in advance, wherein lookup table data is stored for each response speed characteristic of the LCD. Thus, without rewriting of lookup table data, the liquid crystal display device having the lookup table most suitable for performing the overshoot drive is realized while high display quality is maintained therein.
