How to control the display's backlight in the sketch?

Using Arduino Displays

psteve:
The current consumption respectively 86-105-118 mA.

:astonished: How is that possible, if the PWM pin should not "give" more than 25mA ? And with LEDs OFF, it still use 86mA current? What I don't understand here... can you explain?

Thanks :slight_smile:
