Puisqu'on évoquait l'utilisation de dalles 8bits Hi FRC sur les HDG Sony 2016, voici une explication du FRC et ce que cela peut impliquer pour ceux que ça intéresse :
"Frame Rate Control / Temporal Dithering : Frame-Rate-Control (FRC), also referred to sometimes as temporal dithering works by combining four colour frames as a sequence in time, resulting in perceived mixture. In basic terms, it involves flashing between two colour tones rapidly to give the impression of a third tone, not normally available in the palette. FRC is also used to enhance the colour depth of 8-bit panels, boosting them from their standard 16.7 million colours to 1.07 billion in the case of "10-bit" panels (8-bit + FRC). There are a number of FRC algorithms which vary in their effectiveness. Sometimes, a twinkling artefact can be seen, particularly in darker shades, which is a side affect of such technologies."
Certaines personnes semblent être un peu gênées par le procédé :
"The color depth of 8-bit FRC is similar to 10-bit - you lose a bit at the high-end - so some of the very light shades get blown out to pure white, or a very bright color.
However, the main problem that bothers some people (it bothers me terribly) is the shimmering and flickering of the pixels.
FRC simulates 10 bit color by swapping pixels between 2 near colors very quickly. Some people notice the flickering of the pixels as they change color. It looks a bit like an old analog TV with a slight amount of static in the picture."
