Huawei Mate 50 RS Porsche is Huawei's latest new machine launched this year, not to mention the performance configuration of the mobile phone, just look at the appearance design will instantly fall in love with it, the performance of this mobile phone in all aspects is very good, of course, there will be some problems in the process of using the mobile phone, if you have questions such as Huawei Mate 50 RS Porsche supports DC dimming, then follow the editor to take a look at the following article introduction!

Does Huawei Mate 50 RS Porsche support DC dimming

No, but there is 1440Hz high-frequency PWM dimming

PWM is pulse width modulation, and controlling the brightness of the screen is actually the use of the visual persistence effect of the human eye, and the principle is to achieve brightness and darkness changes through the alternation of bright and off screens when all OLED pixel units maintain high display power. Many people have questioned that the flickering produced by the "on-off alternation" will cause damage to the human eye.

In fact, because the human eye is exposed to low-frequency flash stimulation for a long time, it is easy to produce visual fatigue, which may cause discomfort to the eyes and even the body. The IEEE Society of Engineers points out that not all PWM dimming is eye-catching. When the flickering frequency exceeds 1250Hz, the effect on the human eye is greatly reduced.

Therefore, high-frequency PWM not only has the advantage of being better than DC dimming and poor low-brightness display effect, but also overcomes the problem of visual fatigue caused by low-frequency PWM dimming, which can be called the best strength partner of OLED screen.
