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： 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.

摘要： The present invention relates to a display apparatus to synchronize a synchronous signal and an inverter driving signal in response to a display mode, and a control method thereof. A back light unit of the display apparatus makes a back light to dim based on an inverter driving signal, and a dimming frequency of the back light varies in response to a synchronous signal frequency of the image. When a synchronous signal having an abnormal frequency is inputted to the back light unit for several seconds, the back light unit holds the frequency of the inverter driving signal and the frequency of the inverter driving signal varies smoothly in response to the display mode.

摘要： A timing controller includes a count control circuit, a pulse width detector, and a pulse generator. The count control circuit receives an external enable signal. Pulses of the external enable signal include an effective and a blank period of image data. The count control circuit counts pulse widths of each of the pulses. The pulse width detector receives the counted pulse widths, compares a pulse width of a present pulse with pulse widths of previous pulses, and detects a pulse width of a previous pulse that has a pulse width smaller than the pulse width of the present pulse. The pulse generator generates three output pulses having pulse widths that are one-third a period of the detected previous pulse. The pulse generator outputs the first, second and third pulses as an internal enable signal.
