Patent ID: 8018444

Claim:
A data driving circuit comprising: a sampling latch part comprising a plurality of sampling latches for sampling data; a holding latch part comprising a plurality of holding latches for storing all of the data sampled by the sampling latches; a signal generation part comprising a plurality of digital-to-analog converters for receiving the data and for generating data signals; a first switching part located between the holding latch part and the signal generation part; and a second switching part coupled to the signal generation part, the second switching part being for transmitting the data signals to data lines, wherein the first switching part is configured to couple each of the holding latches to a respective first one of the digital-to-analog converters during a first frame, couple each of the holding latches to a respective second one of the digital-to-analog converters during a second frame, and couple each of the holding latches to a respective third one of the digital-to-analog converters during a third frame, wherein the respective first, second, and third digital-to-analog converters are different digital-to-analog converters, wherein the number of the digital-to-analog converters is larger than the number of the holding latches, and wherein the first switching part is further configured to output at least a part of the data received from each of the holding latches to the respective first one of the digital-to-analog converters such that the data is shifted in a first direction by one or more channels during the first frame, output at least a part of the data received from each of the holding latches to the respective second one of the digital-to-analog converters such that the data is not shifted during the second frame, and output at least a part of the data received from each of the holding latches to the respective third one of the digital-to-analog converters such that the data is shifted in a second direction opposite the first direction by one or more channels during the third frame.
