If diffusion control can produce more colors than RGB composition, the conventional wisdom will change. Until now, the number of colors that can be emitted by RGB composition is small, so you will find a color on the CRT and create a similar color. But what if the color cannot be displayed on the CRT? You will probably notice that there is no way to check the color except to make it emit light with diffusion control. The next time I look at the subtle color changes, I wonder how this color looks to others. Since the hues of green and yellow are close, I suspect that some people may see this pale green as pale yellow. Of course, it doesn’t matter what color the dimming chip itself is. I’m sure that the colors you see are slightly different for each person, and no one can shoot a video of such colors. Can you believe such common sense?
