Title: NHD-1.8-128160EF-CTXI#-F LED Backlight current
Post by: geej on April 26, 2016, 09:10:11 PM
Hi there,

Datasheet for NHD-1.8-128160EF-CTXI#-F shows the Backlight Supply current to be 30mA (typ. @Vled3.2V). There appear to be 2 LEDs in this backlight, with a common anode (so in parallel). So is this current the total or for each LED?

Thanks

Hello,

The 30 mA will be for both LEDs.
The current will be divided to both LEDs which are in parallel.
