    摘要: A source driver includes a gamma voltage generator and a digital to analog converter. The gamma voltage generator generates a plurality of gamma voltages, in which the gamma voltage generator includes a gamma resistor string, a second resistor, a plurality of first switches and a second switch. The first resistors are electrically connected serially for dividing a first gamma reference voltage and a second gamma reference voltage, in which the first resistors have first ends and second ends for providing gamma voltages. The second resistor has a first end electrically connected to the gamma resistor string and a second end receiving a third gamma reference voltage. The first switches are uniformly conducted to the first ends or the second ends of the first resistors according to a timing control signal for passing the gamma voltages.

    摘要: A source driver includes a gamma voltage generator, in which the gamma voltage generator includes a first gamma resistor string and a second gamma resistor string. The first gamma resistor string receives a first gamma reference voltage and generates a plurality of first gamma voltages. The second gamma resistor string receives a second gamma reference voltage and generates a plurality of second gamma voltages, in which the second gamma voltages have different voltage values from the first gamma voltages. The switch circuit selects the first gamma voltages or the second gamma voltages as output gamma voltages according to a timing control signal. The digital to analog converter selects one of the output gamma voltages as a driving voltage corresponding to a received digital pixel data for driving a first pixel region or a second pixel region of the sub-pixel.

The digital-to-analog converter includes a first and a second resistor strings, a first and a second select units. The first resistor string is connected between a first and a second power supply voltages to generate a first group of reference voltages. The first select unit selects two reference voltages out of the first group according to M most significant bits of the N-bit digital signal. The second resistor string is connected between the selected reference voltages to generate a second group of reference voltages between the selected reference voltages. The second select unit selects one reference voltage out of the second group as the output analog voltage according to the N-M least significant bits of the N-bit digital signal.
