Apparatus and method for data transmission

摘要

The present invention discloses a data transmission apparatus and method to lower a data transmission voltage for eliminating EMI. In the data driving apparatus, a timing controller aligns input pixel data, lowers input data voltages of the input pixel data, and outputs to a plurality of data transmission lines. A data driver raises the lowered input data voltages for driving the liquid crystal display panel and then converts into analog pixel voltage signals to supply the analog pixel voltage signals to the data lines.
