SH1106 - Turn Background Light ON and OFF

Other Hardware Displays
1

Hello there :slight_smile:

I've just started working with the SH1106 OLED Display.
I was wondering if it is possible to turn the Backgrund light off and on according to the value of an LDR for example.
Or if you can dim it at least to adopt to the sunlight shining on the LED Display.

I want to do this, to expand the Batterys Life depending on the surrounding light if that meks sense.
For the Display itself I am using the <Adafruit_SH1106.h> on an standard Arduino

Unfortunatley I couldnt find anything usefull so far :frowning:

Thank you all in advance for your time and Ideas!
Cheers

OLEDs do not have a backlight.

You can adjust the contrast register on a SH1106 (reg 0x81)
And you can turn display Off / On (reg 0xA4 / 0xA5
