Presto screen burn in?

Support
1

I wrote my first mini app to display some text from a webpage, it works great and I’m very happy.

I was wondering though with the Presto being on continually and with white text on a black background, will this cause burn in?

I’ve not come across any standby code, do we have to handle this? Is this why the world clock has this canvas textile background?

I could look at solutions like updating the text in slightly different coordinates or fading to black until the user touches the screen but I’m not sure if it’s necessary as I can’t find information.

It might be worth buying the multi-sensor stick for the proximity sensor?

Thanks in advance

I was also worried about the same thing. I offset the text slightly each time I draw it (every few minutes). But have no way of knowing if this is necessary or effective.

I’ve discovered that depending on the build the following functions can be used

presto.set_backlight(...) or presto.display.set_backlight(...) which takes a value between 0 and 1 to dim the backlight for example after a period of inactivity or using the optional proximity sensor.
