Ground and Current Return
GND: 80%; Open/1.6V: 100%; High (3.3V) 110%, Luminance
BL On-Off: Open/High (3.3V) for BL On as default
External PWM/Analog Dimming Control input;
Open/High (3.3V, 100% Duty) for 100%
GND: External PWM dimming;
Open/High: Analog dimming.
Note (1)
VDIM is control signal for Inverters output Power to Back Light Lamp Bulb. Input Signal
should be able to control Amplitude of Inverter Output voltage. From 0V to 3.3V, Inverter
Output Voltage should be able to vary to control Brightness of Lamp from 80% to 110%
Luminescence variation. Approx. 1.6V might be 100% Luminance control point.
Note (2)
PDIM is PWM duty control Input for +3.3V TTL Level Signal. This Input Signal is Continuous
Pulse Signal with +3.3V, TTL Level Signal Spec. If this is Open or +3.3V, 100% Duty (i.e.
+3.3V, DC level), Back Light should perform 100% Luminance. Duty Ratio of this Input
signal should be proportional relationship in certain range of control without any kind of
inherent side effect like Waterfall effect on Screen. Guaranteed Duty Range and Dimming
Ratio should be specified with supplementary measurement result.
Note (3)
14 Pin is selection pin for PWM control method; if this pin is connected to GND, PDIM input
of 13th Pin should have Logic Level Duty Signal for PWM control. If this is set to High or
Open, 13th Pin should have DC level signal therefore the Inverter should have Saw Tooth
Wave Generator to generate internal PWM signal. Default setting isAnalog, means when it
is Not Connected, 13th pin of PWM control should be have DC Level signal for PWM.
