Note 1: PWM dimming function can be operated by PWM signal. PWM duty cycle can adjust white Luminance.
(PWM High: ON and PWM Low: OFF)
Note 2: PWM signal can not be floating and pull-down to ground when waiting.
Note 3: Enable (VLED On/Off) must be turned on late than VLED and PWM Signal.
Note 4: Enable (VLED On/Off) must be turned off early than VLED and PWM Signal.
Note 5: If G057VN01 V1 module is driven by high current or at high ambient temperature & humidity condition. The
operating life will be reduced.
Note 6: Operating life means brightness goes down to 50% initial brightness. Minimum operating life time is estimated data.
Note 7: See Section 6.6 for LED Backlight Unit Interface Signal Description
