Note (1) LED current is measured by utilizing a high-frequency current meter as
shown below:
Note (2) At 190 ~1kHz PWM control frequency, the duty ratio range is restricted
from 5% to 100%.
At 1K ~20kHz PWM control frequency, the 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. It is
suggested that PWM control frequency be less than 1KHz.
