  • Voltage regulator, voltage regulation method, and liquid crystal display device using the same
    Patent number: 8686983
    Abstract: A voltage regulator for controlling a reference pulse-voltage comprising a sequence of positive-negative pulses which defines an active range and a dummy range is disclosed. The voltage regulator includes an acquisition unit adapted to receive each pulse of the reference pulse-voltage and determine whether an alteration of the pulse is needed according to a predetermined calculation, and generate a result message when it is determined that an alteration of the voltage pulse is needed, and a voltage control unit adapted to generate an output pulse-voltage corresponding to the reference pulse-voltage. When no result message is generated, the voltage control unit is configured to output an output pulse having the same polarity as that of the received pulse of the reference pulse-voltage, and when the result message is generated, the voltage control unit is configured to output an output pulse having an opposite polarity to that of the received pulse.
