LCD35 power usage vs backlight

Unread post by mad_ady » Mon May 01, 2017 4:21 pm

I was wondering if the backlight PWM level can affect the power usage of the LCD35, or is the backlight always on and the PWM just controls the LCD?
From the side the diffusor looks bright, so I think that PWM doesn't affect the light source, but I need confirmation.

The PWM changes the LED backlight brightness.
So darker backlight should lower the power consumption.
