Weird stripes on image rendering

Post by Facchini » Sat Dec 27, 2014 3:16 pm

Hello,

I followed the recommendations for high res images as here : https://github.com/freetronics/FTOLED/w ... aying-BMPs

Although I got really weird stripes ( horizontal ) as the picture attached shows.

note: please ignore the diagonal things on the images, my iphone couldn't capture it properly.


What should I do to increase the image rendering quality?

Hi Facchini,

Sorry for the slow reply.

The horizontal marking is unfortunately an artifact of the "OLED" display type when displaying large areas of light colours. If you look at existing OLED displays in products, you'll find that most of them use black or very dark backgrounds for this reason.

If you can rework your display to use a black background then the problem will go away.
