Abstract (en)
[origin: EP1895496A2] A method and an apparatus capable of increasing the video depths depending on the video content of each line in order to provide a maximum of color gradation for each given scene shall be proposed. For this purpose there is disclosed an apparatus for driving a display device (16) including input means (11) for receiving a digital value as video level for each pixel or cell of a line of the display device (16), reference signalling means (19) for providing at least one reference driving signal and driving means (15) for generating a driving signal on the basis of the digital value and the at least one reference driving signal. The apparatus further includes adjusting means (18) for adjusting the at least one reference driving signal in dependence of the digital values of at least a part of the line.
