OLED Display Off Command

(1/1)

AngeloR:
We are using an OLED display (NHD-0420DZW-AB5) in a battery backed up application.  How much power can I expect to save when issuing a Display Off command?  We can put some electronics in between the screen and the power supply, but a software solution is a bit cleaner.

Thank you,

Angelo

Michael_L:
You can expect to save approximately 20mA of current drawn by the display.

AngeloR:
Thank you.  It looks like an actual power down saves us around 100mA on the 12V circuit which is significant in our application.

If we elect to actually perform a power down, can you confirm we will have to re-initialize the screen?

Thanks,

Angelo

Michael_L:
Correct.  If the display is powered down, you would need to re-initialize it.
