"Now, the DVDshrink guy's is a bit worse than the other guy's in this respect, but when the display is showing pure blue, aren't you effectively only exercising 1/3 of the set's phosphors? Seems like this is exactly 1/3 as effective as a purely white screen. So if the DVD cycles through R,G,B,White for one unit of time each, each phosphor is only getting exercised for 2 units of time per cycle."
I think the idea, and please someone correct me if I'm wrong, is to give ALL the phosphors an EVEN workout. Again, if I'm mistaken please somone correct me, but the plan is to age the phosphors equally, and unless there is a specific shade or colour that is exactly 33.3% red, 33.3% green and 33.3% blue then this way would be the best (or at least very effective as well as SIMPLE
). If I am not mistaken, the initial period is when the phosphors are at the point most likely to cause IR, so graduating them in phases and repeating ensures good even usuage of each phosphor without risk of retaining any image.
