Method of and unit for displaying an image in sub-fields

摘要

A display unit displays an image on a display screen like a plasma display panel in a number of sub-fields. The display unit is arranged to control the intensity values of one of the color values of a pixel, in particular to control whether the highest weighted sub-field is switched on or off, by changing that color signal. The effect of this change on the luminance of the pixel is compensated by a change to one or both of the other color signals.
