In recent years, domestic smartphone manufacturers have not only been continuously enhancing various performance indicators in high-end flagship products but also relentlessly improving the performance of mid-to-low-end products. The screen, as an indispensable component of a smartphone, clearly demonstrates the importance of performance parameters and optimization tuning.
Different manufacturers have their own focus areas when it comes to screens. For example, Samsung and Apple place more emphasis on the color accuracy and expressiveness of the screen. However, in recent years, domestic smartphone brands have increasingly emphasized the brightness and eye protection functions of the screen. For instance, Honor has introduced Oasis Screen Technology, OnePlus has launched Vision Protection Technology, and Xiaomi has its Qing Shan Screen Technology. All of these reflect the recognition and importance that domestic smartphone brands place on "eye protection."

Before OLED screens became widely used in smartphones, LCD screens were the mainstream. Manufacturers rarely emphasized eye protection features. This was mainly due to the significant differences in dimming technologies used by LCD and OLED screens: LCD screens utilize DC dimming, which is more effective in protecting the eyes compared to the PWM dimming method used by OLED screens. Despite the clear advantages of OLED screens in color representation and contrast, the characteristics of their PWM dimming method have led some users to prefer LCD screens, hence the steadfast slogan among enthusiasts: "LCD shall never be enslaved."
However, with continuous advancements in screen technology, manufacturers have developed dimming methods for OLED screens that rival those of LCD screens, including high-frequency PWM dimming and DC-like dimming technologies. Manufacturers are putting effort into increasing the dimming frequency, as generally, the higher the frequency, the better the protection for the eyes.

Just two years ago, high-spec screen features were the exclusive realm of high-end flagship smartphones. Now, these characteristics have become widespread among mid-range and budget devices. This shift underscores the rapid advancement in screen technology, which has become a critical battleground for smartphone manufacturers across the market spectrum. The widespread adoption of this technology, coupled with reduced costs, has enabled an increasing number of consumers to enjoy the benefits of advanced screen technologies—such as high refresh rates, enhanced brightness, and low blue light emissions—at more affordable prices.
The recent surge of mid-range models boasting superior screens highlights this trend. Even in the mid to low-end market segments, consumer expectations for screen quality are continuously escalating. To meet these demands, manufacturers are compelled to invest more in screen technology and innovation.
Looking ahead, as screen technology continues to evolve and improve, there's every reason to believe that the visual experience of smartphone screens, from high-end flagships to budget-friendly models, will reach new heights.
