摘要： A liquid crystal display device includes a gate driving shift register having symmetrically split circuit portions by which each of plural gate lines is dually driven from both ends of the gate line during ripple-through scanning of rows of the LCD device. The LCD device includes a timing controller generating an output enable signal and a gate clock, where the timing controller adjusts a timing of a load signal for deciding a data output timing point when data will be loaded into a currently activated display row. The data output timing point is a function of a delay measuring feedback signal that is used to measure the cumulative delays of the sequentially connected stages of the shift register.

摘要： Driving apparatus for a display panel having a plurality of pixels includes a plurality of gate line sets connected to the pixels and transmitting a gate-on voltage to the pixels, a plurality of data lines connected to the pixels and transmitting a normal data voltage and an impulsive data voltage to the pixels, a signal controller for converting an input image data of a first gray to an output image data of a second gray and outputting the converted data, a data driver connected to the data line and applying the normal data voltage and the impulsive data voltage corresponding to the output image data to the data line, and a gate driver connected to the gate line and applying the gate-on voltage to the gate line according to a control of the signal controller. The normal data voltage is sequentially applied to a first gate line set among the plurality of gate line sets, and the impulsive data voltage is sequentially applied to a second gate line set among the plurality of gate line sets. The output image data of the second gray is determined in consideration of luminance display time of a pixel charged by the normal data voltage. Accordingly, luminance deterioration by different luminance display times for respective pixel rows connected to respective gate lines in the gate line set can be prevented.

摘要： A LCD includes: a display panel and a signal controller. The display panel includes n pixels arranged in a matrix, wherein n is a natural number. The signal controller sequentially receives first through 2n-th pixel image signals, sequentially calculates a difference between a k-th pixel image signal and a (n+k)-th pixel image signal, recognizes the (n+k)-th pixel image signal as a motion signal when the difference is greater than a first reference value and recognizes the (n+k)-th pixel image signal as a non-motion signal when the difference is equal to or less than the first reference value, and determines whether the (n+k)-th pixel image signal is a moving-image signal based on numbers of motion signals and non-motion signals recognized. An image signal of a previous frame includes the first through n-th pixel image signals and an image signal of a current frame includes the (n+1)-th through 2n-th pixel image signals.
