    Why smartphone companies don't care about Dc Dimming and PWM flicker?

    Posted: 14 Apr 2021 06:20 AM PDT

    • What is Dc Dimming and PWM flickering?

    Here's a short and sweet explanation on this topic.

    To summarize, screen flashes on OLED panels heavily when the screen brightness is set to less than 60%

    The lower you go from that percentage, the more you will experience it. With the naked eye, it's not noticeable but with another smartphone camera, you can observe what's going on on your screen.

    • Why we should talk about it?

    To focus correctly on the screen our pupil needs to adjust (grow big or small very quickly). It's like someone is turning on and off a tiny torchlight in front of your eyes.

    The way I see it, it's already hurting people with sensitive eyes. It's really common to have them nowadays. For the rest of the people, it will harm them eventually. The situation will be worse for people who stream videos, play a lot of games, or read books on their phones. You cant always keep the brightness at a higher level while using your phone indoors and at night.

    There are other problems. For instance, in lower brightness, some phone doesn't come out of the lock screen when you press the power button.

    Or

    When it opens it gives you a bright flash which will hurt your eyes.

    • What is the solution?

    Now all these problems regarding screen flickering in OLED can be solved by simply turning on Dc Dimming. It will decrease the sharpness of the screen(not that noticeable) in low brightness situations and will save you from all these hassles. When you go past 50%, Dc Dimming will go away and the screen will work normally. You can also use apps like OLED Saver and PWM free to get rid of it. But these apps are old and come with their problems.

    • What companies are doing about it?

    OnePlus was the first company to implement that feature and some others followed them. The issue is they are too inconsistent. They put this feature in an update and the next update it's gone. I'm guessing they thought of its significance and then they found out people don't know or care about it so they just excluded it.

    • Why this post?

    Went to the doctor yesterday to check why my eyes are irritating me. Doc asked me if I was using my phone in low brightness and I replied "yes, I keep the brightness between 30-40%". He warned you are not the first person I encountered with this issue and the problem might be with your phone.

    • Conclusion

    OLED is great. The sharpness and contrasty looks are cool! But it comes with its problems. I'm hoping I'm one of those small percentages of people that were exposed to it. I only wish smartphone companies were caring more about our eyes.

    (This post was from my standpoint and I might be wrong about the things I explained here. Please do correct me if I'm wrong)
