Persistence in OLED displays?

Hi all:

I was wondering if the OLED displays (just like the ones in the Dronebot Workshop tutorials) suffer from persistence effects when they display the exact same data for a long period of time?  I plan to use the same displays and would like to know if I should plan to change the coding of the program to mitigate the effect if they do have persistence issues.

I thank you for your feedback!

Interesting question... I'm wondering about the same (potential) issue

Hi all:

So I posed this question on the Arduino forum and the consensus seems to be that they definitely do suffer from “burn-in”.  To mitigate this, two recommendations were to set the brightness as low as possible to be readable and perhaps to use a small, microwave proximity sensor to keep the display turned off unless someone is nearby...

You could blank the screen then flood fill it white.

If you did that periodically that would help stop screen burn. 

I have a 1.2 “ IC2 oled screen.  I haven’t done much with it yet though.  One of the demo’s has a white bar which does a vertical and horizontal wipe.  It then does a fan from vertical to horizontal.

it only takes a few seconds to run all three wipes but running something like that every few minutes would help stop screen burn too.

 

Regards

Dave
