What to do when adding Ace 2V high-frequency dimming to automatically turn off

As one of the most cost-effective mobile phones at present, the Ace 2V has attracted many users to purchase. Many of them found that after turning on high-frequency PWM dimming, their phones would automatically turn off this function before long, and then had to turn it back on again, which was very troublesome. So what should I do if I add Ace 2V high-frequency dimming to automatically turn off? Let's take a look together with the editor below.

What should I do if I add Ace2V high-frequency dimming to automatically turn off? Solution for automatic shutdown of Ace2V high pass dimming in OnePlus

After turning on high-frequency PWM dimming, restarting the phone can solve the problem

The principle of PWM (Pulse Width Modulation) is to alternately flash the screen with a certain frequency of "on → off → on → off" in an extremely short period of time. By adjusting the time ratio of "on" and "off", the screen brightness can be adjusted from 0% to 100%. But the most criticized aspect of the PWM dimming scheme is the flicker problem. During the PWM dimming process, if the working frequency is very low, the human eye will feel flickering. So in order to fully utilize the visual residual phenomenon of the human eye, the higher the working frequency of PWM dimming, the better - according to international standards, PWM dimming is positively correlated with screen flicker, but when the PWM frequency exceeds 1250Hz, it will not have a significant impact on vision.

In summary, if there is a phenomenon of high-frequency PWM dimming automatically turning off, restarting the phone after turning it on can solve this problem. If you have any other questions about OnePlus Ace 2V, you can continue searching on your mobile cat.
