Patent ID: 8009135

Claim:
A source driver for driving a display panel, the source driver comprising: a sample/hold circuit for receiving a first voltage and a second voltage and for outputting a first sampled-held voltage and a second sampled-held voltage; a first low voltage amplifier for receiving the first sampled-held voltage and for generating a first low pixel voltage, which is within a low-voltage range; a second low voltage amplifier for receiving the second sampled-held voltage and for generating a second low pixel voltage, which is within the low-voltage range; a first multiplexer with one output for outputting one of the first low pixel voltage and the second low pixel voltage according to a polarity signal; a high voltage amplifier connected to the output of the first multiplexer, the high voltage amplifier configured to generate a high pixel voltage within a high-voltage range; a second multiplexer for outputting one of the first low pixel voltage and the high pixel voltage to a first data line of the display panel according to the polarity signal; and a third multiplexer for outputting one of the second low pixel voltage and the high pixel voltage to a second data line of the display panel according to the polarity signal.
