s lamps of connected
displays.
LVDS_PPEN: VCC_LCD electrical level Output with a 10k
Ω
pull-up resistor, Panel Power Enable signal. It can be used to turn On/Off the connected display.
BLT_CTRL: this signal can be used to adjust the backlight brightness in displays supporting Pulse Width Modulated (PWM) regulations (VCC_LCD electrical level).
LVDS_BLT_ANA: Analog dimming for LVDS panel backlight, electrical level ranging from 0V up to VCC_LCD
