Abstract:
A method of driving a thin-film transistor liquid crystal display (TFT-LCD) device comprising pixels arranged in a matrix and containing dots of one of a plurality of basic colors such that each basic color is contained in each pixel, the basic colors being red (R), green (G), and blue (B), said dots being matrix-driven by scanning lines and signal lines, said dots arranged along each signal line and said pixels arranged repeatedly along said signal and scanning lines, each pixel having color filters covering each dot and forming an arrangement with a first sequence of R-G-B along each signal line and a second sequence of the same color along each scanning line, the arrangement of said color filters being the same in all said pixels, wherein the number of scanning lines is the number of pixels repeatedly arrayed along the signal lines multiplied by the number of basic colors, and the number of dots arrayed along each of the signal lines is the number of pixels arrayed along each of the signal lines multiplied by the number of basic colors, and the number of dots arrayed along each of the scanning lines is the number of pixels arranged along each of the scanning lines, wherein the TFT-LCD device has at least one gate driver with a plurality of gate outputs corresponding to the amount of scanning lines and at least one source driver with a plurality of source outputs corresponding to the amount of signal lines,said method comprising:dividing a frame of display information into a first field, a second field, and a third field, wherein the pixels in each field are classified in the signal line direction according to the progression of n, n+1, n+2, n+3, n+4, . . . , and n+m, where m is any integer greater than or equal to 5, where n is the first pixel in the scanning and signal lines; andsequentially driving the first, second, and third fields by scanning a reduced number of said scanning lines to display the frame according to the display information, wherein,in the first field,red scanning lines are scanned in pixels n and n+3,green scanning lines are scanned in pixels n+1 and n+4,blue scanning lines are scanned in pixels n+2 and n+5,in the second field,green scanning lines are scanned in pixels n and n+3,blue scanning lines are scanned in pixels n+1 and n+4,red scanning lines are scanned in pixels n+2 and n+5,in the third fieldblue scanning lines are scanned in pixels n and n+3,red scanning lines are scanned in pixels n+1 and n+4,green scanning lines are scanned in pixels n+2 and n+5, andvoltage polarity is reversed from one pixel to the next pixel along the signal lines and from one dot to the next dot along the scanning lines, wherein pixel n has positive voltage polarity.
