Patent ID: 8411018

Claim:
A source driver for driving a display having a plurality of pixels spatially arranged in a matrix form, and a plurality of data lines, each data line being associated with pixels of a corresponding pixel column, comprising: (a) a first pair of switches, a second pair of switches, and a third pair of switches, controlled by a control signal; (b) a first analog circuit having a first input electrically coupled to one of the first pair of switches for receiving a first converted signal or a second converted signal, a second input for receiving the power supply voltage, a third input for receiving the ground voltage, and an output for outputting a first amplified signal; (c) a second analog circuit having a first input electrically coupled to the other of the first pair of switches for receiving the first converted signal or the second converted signal, a second input for receiving the power supply voltage, a third input for receiving the ground voltage, and an output for outputting a second amplified signal; (d) a first output stage with a positive polarity having a first input electrically coupled to the output of the first analog circuit and the output of the second analog circuit through one of the second pair of switches for receiving the first amplified signal from the first analog circuit or the second amplified signal from the second analog circuit, a second input for receiving the power supply voltage, a third input for receiving the first middle voltage, and an output for outputting a first data signal; and (e) a second output stage with a negative polarity having a first input electrically coupled to the output of the first analog circuit and the output of the second analog circuit through the other of the second pair of switches for receiving the first amplified signal from the first analog circuit or the second amplified signal from the second analog circuit, a second input for receiving the second middle voltage, a third input for receiving the ground voltage, and an output for outputting a second data signal, wherein each odd data line of the plurality of data line are electrically coupled to the output of the first output stage and the output of the second output stage through one of the third pair of switches for receiving the first data signal from the first output stage or the second data signal from the second output stage; wherein each even data line of the plurality of data line are electrically coupled to the output of the first output stage and the output of the second output stage through the other of the third pair of switches for receiving the first data signal from the first output stage or the second data signal from the second output stage; and wherein the third pair of switches is configured such that each odd data line of the plurality of data line receives one of the first and second data signals, while each even data line of the plurality of data line receives the other of the first and second data signals, and vice versa.
