Det is Output pin for detect power error.
PDIM is PWM duty control input for +3.3V TTL level signal or DC voltage by Pin 14 input.
This input signal is (a) continuous pulse signal with +3.3V, TTL level signal spec, or (b) DC
power with 0~3.3V. If this is Open or +3.3V, 100% duty (i.e. +3.3V, DC level), backlight
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.
Pin 14 is the selection pin for PWM control method; if this pin is connected to GND, PDIM
input of Pin 13 should have logic level duty signal for PWM control. If this is set to High or
Open, Pin 13 should have DC level signal therefore the Inverter should have Saw Tooth
Wave Generator to generate internal PWM signal. Default setting is “Not Connected”, Pin 13
of PWM control should have DC Level signal for PWM.
Pin 14 selection vs. Pin 11/13 control function table:
Pin 13
Default: Open/High: 100%
Pin 14 = GND
Pin 14 = Open/High

(AC Signal Control Duty)
Internal PWM
