Muchas gracias por la respuesta, perfectamente explicado.
Buscando que era DFC me he encontrado con esto en avsforum:
There are two main driving methods for Plasma displays.
1 - Binary (Panasonic) - Pulse widths are weighted in Binary (8subfields = 1,2,4,8,16,32,64,128) and combinations of these weights make up 256 possible levels per subpixel. Newer Panasonic models claim 10 subfields which adds up to 1024 levels per subpixel.
2 - Contiguous (Pioneer) - Pulses can only be adjacent to each other (one after another) and therefore the number of subfields equals the number of possible gray levels per subpixel. Pioneer uses 14 subfields and thus only 14 gray levels per subpixel.
The amount of "equivilent" gray levels is generally the total amount of gray levels the panel is capable of creating through a combination of true sub-pixel gray level, error diffusion, spacial dithering, and temporal dithering.
Pioneer chose the path of Contiguous driving to completely eliminate the artifact known as DFC (Dynamic False Contouring) even though it meant a higher black level and the need for sophisticated Halftoning. Ironically, this decision ultimately led to the revolutionary KURO blacks and ECC.
