Because the human eye is more sensitive to changes in dim light than changes in bright light, Omron’s LED drivers were designed to better match this visual characteristic and help address some of the issues caused by conventional methods. The Omron LED driver not only makes exponential adjustments to the duty cycle, but uses a total of 1024 gradations. Please refer to figure 3-a. The result is a very gradual and very smooth transition where the LED can be fully off from the start and move through all 1024 gradations to achieve full brightness. This transition is very appealing to the human eye and has no noticeable flicker or stepping effects. Please refer to figure 3-b.
