Abstract: An image control device has display signals and blank insertion (BI) signals. Polarities of the display signals and those of the BI signals are coincident. Thus, BI signals are displayed in a way of 1+2 line inversion and differences of response times are eliminated to avoid affecting MPRT.

Abstract: A source driver of an LCD includes a shift register, a set of data latches, and a detection circuit. The shift register includes a plurality of flip-flops for transmitting a start signal. The set of data latches transmits the display data signal according to output signals of the corresponding flip-flops. When the start signal is recognized as a black insertion signal, the detection circuit resets the shift register, and drives the set of data latches to output the black data signal, and transmits the black insertion signal to the next source driver.

Abstract: 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.
