Control method
Note 1: Luminance control may be overlap noises on the display image depending on input signal timing. In this

case, keep off the interference between input signal and backlight driving signal, by PWM method.
Luminance controlled by BRTP signal.
See “(4) External pulse control for luminance”.
The variable resistor for luminance control should be 10 kΩ type,
and zero point of the resistor corresponds to the minimum of
luminance.
Max. luminance (100%): R = 10 kΩ
Min. luminance (30%): R = 0 Ω
Mating variable resistor: 10 kΩ ± 5%, B curve, 1/10 W
BRTH should be fixed to 0 V, and input to BRTL as follows.
Max. Luminance (100%): 1 V (Typ.)
Min. Luminance (30%): 0 V
