    摘要: A receiving circuit is provided for receiving a data signal and a clock signal, which are RSDS signals, and outputting an output data signal to a data driver. The receiving circuit includes a data comparator, a data intermediate circuit, a clock comparator, a clock intermediate, and a flip-flop. The data comparator, driven with a data bias current, receives the data signal, and outputs a compared data signal. The clock comparator, driven with a clock bias current, receives the clock signal, and outputs a compared clock signal. The flip-flop receives the compared data signal via the data intermediate circuit and the compared clock signal via the clock intermediate circuit. The phase difference between the compared data signal and the compared clock signal is improved by adjusting the data and the clock bias currents.

    摘要: A power-on screen pattern correcting apparatus is for correcting start output data of output terminals of a source driver such that a power-on screen pattern of a display is substantially uniform. The correcting apparatus comprises a flip-flop, a first logic unit and a second logic unit. The flip-flop controls a level of an inner signal to be substantially equal to a low signal level in response to a low level of a power start signal. The first logic unit enables a first signal in response to the low level of the inner signal or a low level of a high-impedance control signal. The second logic unit enables a second signal such that the output terminals are coupled to a charge sharing line and the power-on screen pattern is uniform in response to the low level of the inner signal or a low level of a charge-sharing control signal.

    摘要: A flip-flop is provided. The flip-flop is used in a shift register in a source driver. The flip-flop is used to receive a first clock signal, an input signal and output an output signal. The output signal is fed back to the flip-flop. The flip-flop includes a flop core for receiving the input signal and output the output signal. When the input signal and the output signal are all disabled, the flop core is disabled to function. When the input signal or the output signal is enabled, the flop core is enabled to function to output the output signal.

    摘要: A digital-to-analog (D/A) converter comprises a decoder apparatus and an operational amplifier. The decoder apparatus comprises first and second decoder unit. The first decoder unit selects a voltage of first voltage set as first and second voltage in response to a value of first gray level set. The second decoder unit selects first border voltage of second voltage set as the first and the second voltages and second border voltage of that as the first and the second voltages in response to the maximum and the minimum value of second gray level set respectively. The second decoder unit further selects the first and the second boarder voltage as the first and the second voltage respectively in response to an intermediate value of the second gray level set. The operational amplifier generates a pixel voltage having level between the first and the second voltage accordingly.
