    摘要: A common voltage generating circuit of an LCD includes a first flip-flop, a capacitor, a resistor and a regulating circuit. The first flip-flop receives a data-loading signal from the LCD, for outputting a step signal. The step signal forms a waveform voltage through the capacitor and the resistor. The regulating circuit inverts the waveform voltage and adjusts the magnitude and the DC level of the waveform voltage, for generating a common voltage. Compare to the common voltage of the color filter base plate, the common voltage generated by the common voltage generating circuit have the same frequency and magnitude, but opposite direction. Therefore, by generating the common voltage of opposite direction, the present invention eliminates crosstalk and improves uneven brightness of the displayed image.

    摘要: A division unit, an image analysis unit and a display apparatus using the same capable of simplifying the computation of overall average gray scale are provided. The division unit includes an adder for receiving a first to an Nth bus signals to produce an addition result, wherein the first to the Nth bus signals shift the input signal by a different number of bits and adding logic zeros to the shifted bits as compensation, where N is a positive whole number, and a multiplexer for receiving a most significant bit (MSB) of the addition result, wherein, when the MSB has a first value, the multiplexer treats P bits of the addition result as a division result, and when the MSB has a second value, the multiplexer outputs P logic 1 to serve as the division result, where P is a positive whole number.

    摘要: A display apparatus of a dynamic image and a display method thereof are provided. The display method includes the following steps. An image signal is received and then displayed through either a black insertion (BI) technology or a dynamic backlight luminance (DBL) technology according to image luminance. The image signal is displayed through the BI technology when the image signal is in a bright state and through the DBL technology when the image signal is in a dark state, so as to prevent a zebra effect from being exerted by employing both technologies simultaneously.

Exploiting Fuzzy theorem to analysis the image, which the LCD is going to display, identify the correction strength to several levels and real time correct the image contrast according to the Fuzzy rule and the Fuzzy decision theorem. On the other hand, all image analysis, correction decision, and the contrast correction will be completed during one frame period. Utilizing this FCC method (Fuzzy Contrast Correction) can avoid the over-correction or the under-correction situation, can improve or enhance the image contrast properly.
