    Abstract: A random bit stream generator which includes a pseudo-random bit stream generator and a multi-stage noise shaping (MASH) delta-sigma modulator is introduced. The pseudo-random bit stream generator may generate a first random bit stream according to a first clock signal. The MASH delta-sigma modulator is coupled to the first random bit stream generator to receive the first random bit stream and output a second random bit stream according to the first random bit stream and a second clock signal. A frequency of the second clock signal is greater than a frequency of the first clock signal, and the random bit stream has bell-shaped distribution. A method of generating a random bit stream having bell-shaped distribution adapted to a random bit stream generator is also introduced.

    Abstract: A display driver and a charge recycling method are provided. The display driver includes a charging and discharging circuit and a control circuit. A first terminal of the charging and discharging circuit is coupled to at least one of the scan lines, and a second terminal of the charging and discharging circuit is coupled to at least one of the data lines. The control circuit is coupled to a first control terminal and a second control terminal of the charging and discharging circuit. The charging and discharging circuit receives a first current generated by discharging the at least one of the scan lines to charge the capacitor based on a first control signal. The charging and discharging circuit discharges the capacitor to generate a second current for charging the at least one of the data lines based on a second control signal.

    Abstract: A display control system includes a plurality of driver circuits connected in series. A driver circuit among the plurality of driver circuits includes a receiver, a duty cycle correction circuit and a transmitter. The receiver is configured to receive a first signal from a previous driver circuit among the plurality of driver circuits. The duty cycle correction circuit, coupled to the receiver, is configured to adjust a duty cycle of the first signal to generate a second signal. The transmitter, coupled to the duty cycle correction circuit, is configured to transmit the second signal to a next driver circuit among the plurality of driver circuits.
