摘要： The present invention in one aspect relates to a source driver comprising a first digital-to-analog converter with a positive polarity (PDAC), a second digital-to-analog converter with a negative polarity (NDAC), a first operational amplifier and a second operational amplifier. Each operational amplifier is characterized with a 1st & 2nd stage and an output stage. Both the PDAC and NDAC are coupled to the first and second operational amplifiers through a first pair of switches. The 1st & 2nd and output stages of the first operational amplifier are coupled to the 1st & 2nd and output stages of the second operational amplifier through a second pair of switches. The first and second operational amplifiers are coupled to odd data lines and even data line through a third pair of switches. Further, the amplitudes of the operational voltages for the PDAC, the NDAC and the output stages first and second operational amplifiers are set to be between the supply voltage and the ground voltage. Accordingly, the power consumption and the operational temperature are substantially reduced.
