Simple example of screen image retention test with comments and walk-through in one YouTube video. This test was carried out using a smartphone device. And although the lighting conditions were not perfect, we were still able to capture some image retention. It was even more apparent to a naked eye.
It is worth noting, that this smartphone is still in nearly perfect working condition, and even though it has some image retention, (especially when in full brightness setting) this does not have any inconvenient consequences to it’s daily use.
You can try this exact same test on your devices, but if you do, don’t forget to let us know about the results! 🙂
