<p>A color display device comprises a plurality of picture elements (14), at least two light sources, having different radiance spectra and being activated alternately, and color selection means for generating, together with said light sources, primary colors in a color image (P1, P2). Each of a number of image information sets, each set being related to a color image (P1, P2) to be displayed, are divided into a first subframe (A1, A2), being picture element settings to be maintained during the operation of a first light source, and a second subframe (B1, B2), being picture element settings to be maintained during the operation of a second light source. The polarity of the picture elements (14) is, in an alternating manner, shifted between a first polarity (+) and a second polarity (−). The polarity is shifted in such manner that a first subframe (A1) and a subsequent first subframe (A2) are matched with different polarities (+,−) in order to avoid a polarization in the picture elements (14) which may result in slow response or other artifacts.</p> |
