Abstract:
A method for controlling a data driver, the method which comprises:activating a data driver in dependence of a provided bit sequence for producing, at a data output of the data driver, a data signal such that the data signal, in time periods between periodic reference clock pulse edges, is in each case driven to one of a high validity level and a low validity level in accordance with a binary value of bits of the provided bit sequence, the high validity level being higher than the low validity level; providing a preparation interval of a fixed length directly before selected reference clock pulse edges such that, during the preparation interval, the data driver is prompted to drive the data output of the data driver to a medium level provided between the high validity level and the low validity level, the selected reference clock pulse edges including a first reference clock pulse edge and at least all reference clock pulse edges occurring between data items of different binary values; and providing the fixed length of the preparation interval such that the fixed length of the preparation interval is at least equal to a response time required by the data driver to drive the data output of the data driver over a level difference between one of the low and high validity levels and the medium level, and such that the fixed length of the preparation interval is shorter than twice the response time.
