The number of gradations of diffusion control was 150 million instead of 4H1024. Ciel is a little less. Well, in any case, it’s difficult to control to use up this gradation.
Let’s talk a little about the power saving that was on hold. The maximum power in the PWM method lights all LEDs. Since the diffusion control always drives only one LED even if it emits white light, the maximum power consumption is reduced to 1/3. If you drive only one, another advantage will appear. Generally, when trying to emit white light, the brightness balance of RGB becomes a problem. Since multiple LEDs are driven at the same time, the brightness is compared. If they are driven separately, the difference in brightness will not be felt so much. In other words, with diffusion control, true white can be emitted.
