OLEDs / OLED dark horizontal bands
« on: May 08, 2015, 08:26:46 AM »
Hello,

Iím evaluating the NHD-1.69-160128UGC3 OLED display. I got it working and can draw pictures and graphics on it. Iím using the SPI interface.

Iím experiencing a series of dark horizontal bands that appear in the screen when something is moving (i.e. when animating graphics). These dark horizontal regions span left to right through the entire screen width.

I did not find anything like this in the forums - Is my unit defective? Is this normal for these OLED modules? Have you seen this before?

The picture below shows a vector balls animation; dark bands appear in regions where the animation (This is not a interlace effect due to screen refresh rate and the camera taking the picture; these dark bands can be seen with the naked eye); the background behind the animated balls is supposed to be solid blue.




Best Regards,
-Edwin
