Note (1) LED current is measured by utilizing a high-frequency current meter
shown below:
Note (2) At 190 ~1kHz PWM control frequency, duty ratio range is restricted from
5% to 100%.
1K ~20kHz PWM control frequency, duty ratio range is restricted from
20% to 100%.
If PWM control frequency is applied in the range from 1KHz to 20KHZ,
The "non-linear" phenomenon on the Backlight Unit may be found. So
It's a suggestion that PWM control frequency should be less than 1KHz.
