Abstract
A data driver circuit for an LCD including a switching circuit for transferring a data signal from a data channel to a first data line and a second data line. Also included is a sample circuit which alternately samples the data signal from the first data line and the second data line to produce and store respectively a first and second sampling data signal during a respective first and second time period. A data driver retrieves from the sample circuit the first sample data signal during the second time period and the second sampled data signal during the first time period. Then, the data driver transfers a driving pulse corresponding to one of the first sampled data signal and the second sampled data signal to the display.
