Honor Zhao Ming responds to netizens on screen eye protection technology: Professional evaluation should be trusted

Recently, Honor officially released its Magic6 series, which is regarded as the first flagship domestic mobile phone in 2024. The phone has a series of hardware upgrades, including satellite communications and battery life. At the same time, Magic6 is also equipped with the new MagicOS 8.0 operating system, which is based on the terminal-side platform-level AI large model, bringing a new experience to users. However, some netizens have raised controversy over the screen eye protection performance of Magic6.

Li Kun, flagship mobile phone product manager of Honor Terminal Co., Ltd., published a long article on the controversy, detailing the 8T LTPO screen solution used in the Honor Magic6 series and its excellent eye protection experience.

Li Kun said that the Honor Magic6 series uses the latest generation 8T LTPO screen solution. This technology provides users with top-level eye protection. experience.

Li Kun said in the article: In a medium-to-high brightness environment, when people use mobile phones, the brightness that enters their eyes comes from both the medium-to-high illumination ambient light and the mobile phone screen, and is dominated by ambient light. For example, when the ambient illumination is 500lx, the screen brightness of the Honor Magic6 series is about 150nit, and the measured illumination level of the screen at the eye level is 50~60lx. In this way, the eye brightness ratio accounted for by the mobile phone is only about 10%. In addition, in this scenario , the Honor Magic6 series is DC-like dimming, and the duty cycle reaches 93%. In many documents, human factors tests have concluded that when the duty cycle reaches more than 90%, the frequency of 360Hz under medium and high brightness has no impact on the human eye. Therefore, under medium and high brightness, you don’t need to worry about the impact of the Honor Magic6 series on the human visual experience.

Under medium and high brightness, the display of the mobile phone screen has a great impact on eye comfort. In addition to ambient illumination and color temperature adaptation, screen brightness uniformity, color accuracy and refresh smoothness are also important. The Honor Magic6 series 8T LTPO screen has unique advantages. It combines oasis eye protection technologies such as natural light eye protection and natural color display to provide users with a more comprehensive eye protection effect.

Li Kun pointed out that these results have also been verified by long-term human factors engineering by professional institutions such as China Institute of Standardization and Tongren Hospital.

In a dark light environment, the human eye is very sensitive to changes in screen brightness. According to the IEEE Std 1789™-2015 standard, when the PWM dimming frequency exceeds 3125Hz, stroboscopic risk to the human eye reaches zero risk. The Honor Magic6 series uses ultra-high-frequency PWM dimming technology with a frequency of 4320Hz, and has obtained Rheinland’s flicker-free and zero-risk dimming certification. In addition, this series is also equipped with Honor Oasis eye protection technology, including natural light-like eye protection, sleep aid display, hardware-level low blue light and natural color display, etc., and has passed the VICO A visual comfort test of the China Institute of Standardization.

Subsequently, Zhao Ming, CEO of Honor Terminal Co., Ltd., forwarded this Weibo post and responded to netizens’ messages in the comment area: High-frequency PWM consumes more power when used at medium and high brightness, and will also cause Display brightness is significantly reduced. In comparison, DC dimming is a better choice. Zhao Ming also said: "You can trust this professional judgment."
