OLEDs / OLED In-rush current
« on: February 25, 2016, 09:21:43 AM »

I am having an issue with the NHD-2.7-12864UCY3 drawing very high currents when waking up (0xAF) from extended sleep times (>30 min).

The display is powered by 3.0V and has a 100uF decoupling capacitor just beside it. I am seeing the supply drop to ~2.4 V twice, just after wake up.

Can I set something on the display to reduce the in-rush currents during wake up, but change it later? Maybe ramp up an internal voltage slowly to spread out the in-rush current?

Thank you.
