  • Patent number: 9013386
    Abstract: 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.

  • Patent number: 8669974
    Abstract: 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.

  • Patent number: 7466310
    Abstract: 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.

  • Publication number: 20060164365
    Abstract: An overdrive device for driving a display panel includes a comparison circuit, a multiplexer, and an overdrive module. The comparison circuit receives pixel values of display cells of the display panel in a previous frame carried on a first decompressed data signal and in a current frame carried on a second decompressed data signal, and determines whether the brightness/color of each target display cell is static to assert or de-assert a selection signal. The multiplexer outputs an output signal to output at least a reference pixel value for the overdrive module according to the selection signal. The overdrive module receives the reference pixel value, and overdrives the target display cell according to an overdrive value corresponding to a combination of the received current and reference pixel values stored in a look-up table of the overdrive module.
