Abstract
An image display device wherein pixel drive values are generated on the basis of digital information words. Each information word is translated twice, using a look-up table, first to obtain a drive value for a relevant pixel and then to obtain a drive value for a direct neighbor of that pixel. The pixels may be in successive fields of an interlaced image, in which case the content of the look-up table is replaced between the two translations so as to correspond with the respective interlaced fields. The content of the look-up table for the first pixel provides only a limited range of possible pixel drive values, whereas the content of the table for neighboring pixels provides a broader range of pixel drive values corresponding to interpolations between pairs of drive values in the limited range.
