    摘要： A liquid crystal display (LCD) and an operating method thereof are provided. The operating method includes the following steps. It is determined whether a first frame and a second frame following the first frame are dynamic frames. When the first frame and the second frame are dynamic frames, a timing controller of the LCD performs a polarity inversion on a polarity signal, so that the polarity signal corresponding to the first frame is the same as the polarity signal corresponding to the second frame. When the second frame is written into an LCD panel of the LCD, energy written into the LCD panel is reduced.

    摘要： A liquid crystal display (LCD) including a LCD panel having a plurality of pixels, a source driver outputting a plurality of pixel voltages to the LCD panel, a gate driver, and a timing controller is provided. During performing a polarity inversion on a polarity signal corresponding to a first frame, the timing controller sequentially outputs a first start signal and a second start signal to the gate driver in a first frame period corresponding to the first frame. The gate driver sequentially outputs a plurality of first scan signals and a plurality of second scan signals to the LCD panel according to the first start signal and the second start signal, so that the brightness corresponding to a plurality of gray levels in the first frame are equal to the brightness corresponding to the gray levels in a plurality of previous frames and a plurality of following frames.

    摘要： A timing controller adapted to a flat display includes a voltage detecting circuit, a clock generator, a first multiplexer and a second multiplexer. The voltage detecting circuit detects a variation of an operating voltage and thus outputs a reset signal. The clock generator outputs a start signal and a first clock signal. The first multiplexer is controlled by the reset signal and coupled to the start signal and a constant voltage. The second multiplexer is controlled by the reset signal and coupled to the first clock signal and a second clock signal. A frequency of the second clock signal is obviously higher than a frequency of the first clock signal.

    摘要： A line compensated overdriving circuit for use in a color sequential display is disclosed. The line compensated overdriving circuit comprises an overdrive unit, a line compensation generator, and a line compensated overdrive (LCO) processor. The overdrive unit receives previous data and present data to output overdrive data. The line compensated generator receives a line position of each pixel to output a line compensated factor, and the LCO processor receives the line compensated factor and the overdriven data to generate compensated data for the pixel. Thus, the line compensated overdriving circuit can eliminate the spatial intensity variations associated with the conventional color sequential displays.
