摘要：Plasma Display Panels (PDP) are becoming more and more interesting for TVtechnology. Due to the larger size of PDPs, with larger viewing angle the large areaflicker effect will become more serious in the future, in particular when handling 50Hzvideo standards. This invention proposes a different sub-field organisation, with differentcoding, which reduces large area flicker artefact, and which is characterised by: 1.

Grouping of sub-fields (SF) in 2 sub-field groups (G1, G2), of similar structure.2. The 2 sub-field groups (G1, G2) are identical in terms of the most significant sub-fields (SF) anddifferent in terms of the least significant sub-fields (SF).3. A sub-field coding process thatdistributes luminance weight symmetrically over the 2 sub-field groups (G1, G2) so as tominimise the 50Hz large area flicker luminance component.
