摘要： A data transferring method for the input interface of a liquid crystal display. In the conventional reduced swing differential signal (RSDS) data transferring method, a pair of data lines can transmit a single bit of data. Thus, more data line pairs are required to transmit more data bits leading to a rapid increase in spatial occupancy and production cost. The present invention permits more data bits to be transmitted for the same number of data lines by converting DC levels into AC levels. With two DC levels provided by two pairs of data lines, a third bit of data can be transmitted. Similarly, with four DC levels provided by four pairs of data lines, seven bit data can be transmitted. Since more data can be transmitted with a given set of data lines, space and production cost is saved.
