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.

摘要： In a liquid crystal display equipped with a timing controller, the timing controller generates a restoration signal having a predetermined pulse width in response to a data enable signal and operates in a fail mode when a difference between the data enable signal and the restoration signal is larger than a threshold value. Even if the data enable signal is distorted by electrostatic discharge, the liquid crystal display uses the restoration signal as a data enable signal without entering the fail mode when the distortion degree is smaller than the threshold value. Thus, a user may not recognize the electrostatic discharge when the electrostatic discharge is applied to the liquid crystal display for a short period of time.
摘要翻译：在配备有定时控制器的液晶显示器中，定时控制器响应于数据使能信号产生具有预定脉冲宽度的恢复信号，并且当数据使能信号和恢复信号之间的差异较大时，以故障模式工作超过阈值。即使数据使能信号由于静电放电而失真，当失真度小于阈值时，液晶显示器也可以使用恢复信号作为数据使能信号而不进入故障模式。因此，当在短时间内将静电放电施加到液晶显示器时，用户可能不会识别静电放电。

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.
