PRODUCT SPECIFICATION
VLED rising time is 0.5ms
Note (2) If the PWM control duty ratio is less than 5%, there is some possibility that acoustic noise or
backlight flash can be found. And it is also difficult to control the brightness linearity.
Note (3) If PWM control frequency is applied in the range less than 1KHz, the “waterfall” phenomenon on the
screen may be found. To avoid the issue, it’s a suggestion that PWM control frequency should follow
the criterion as below.
PWM control frequency fPWM should be in the range
(N + 0.33) ∗ f ≤ fPWM ≤ (N + 0.66) ∗ f
N : Integer (N ≥ 3)
f : Frame rate
Note (4) The specified LED power supply current is under the conditions at “LED_VCCS = Typ.”, Ta = 25
± 2 ºC, fPWM = 200 Hz, Duty=100%.
