An LCD driver for driving an LCD having a plurality of segments, wherein each segment is enabled by an RMS voltage exceeding a predefined turn-on threshold is disclosed. The LCD driver includes a control module, a power supply module, a reference module and a selector module. The control module is configured to output at least a clock, a first control, a second control and a third control. The power supply module is configured to receive a supply voltage and the first control, and output the supply voltage to the reference module. The reference module is configured to receive the supply voltage and the second control, and output a plurality of duty cycled and buffered reference voltages. The selector module is configured to receive the buffered reference voltages and the third control, and output one or more of the buffered reference voltages to one or more of the segments of the LCD according to a predefined sequence. |
