April 8th, Xiaomi took to Weibo to tease the screen capabilities of the upcoming Redmi Turbo 3, shedding light on its hardware-level low blue light technology. They touted its superior 1.5K resolution screen compared to peers, boasting a peak brightness of 2400nit and support for a remarkable 2160Hz touch sampling rate. It's a sight to behold for those concerned about eye protection in the digital age.

In recent years, domestic smartphone manufacturers have not only been continuously enhancing various performance indicators in their high-end flagship products but also diligently improving the performance of mid-to-low range products. The screen, as an indispensable component of smartphones, highlights the importance of performance parameters and optimization tuning.
Different manufacturers have their own focus when it comes to the key aspects of screen attention. For instance, Samsung and Apple place more emphasis on the color accuracy and expressiveness of the screen; while in recent years, domestic smartphone brands have increasingly emphasized brightness and eye protection functions of the screen. For example, Honor has introduced the Oasis Screen Technology, OnePlus has launched the Bright Eyes Eye Protection Technology, and Xiaomi has the Green Mountain Screen Technology. These all reflect the recognition and importance that domestic smartphone brands place on "eye protection".
Before OLED screens became widespread in smartphones, LCD screens were dominant. Manufacturers rarely emphasized eye protection features back then. This was mainly because of significant differences in dimming technologies between LCD and OLED screens: LCD screens use DC dimming, which is more effective at protecting the eyes compared to OLED screens' PWM dimming. Despite OLED screens' clear advantages in color rendering and contrast, some still prefer LCD screens due to their DC dimming method, hence the slogan "LCD will 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 techniques. Manufacturers are focusing on increasing the dimming frequency, as higher frequencies generally provide better eye protection.

Just two years ago, high-spec screen parameters were exclusive to top-tier flagship phones. Now, these features have become commonplace even in mid-range and budget products. This shift underscores how advancements in screen technology have become a key battleground for smartphone manufacturers, spanning the entire market from high-end to low-end. The widespread adoption of technology and the decrease in costs mean that more and more consumers can enjoy the benefits of advanced screen technology such as high refresh rates, high brightness, and low blue light at lower prices.
Recent releases of several mid-range phones featuring top-notch screens further highlight this trend. Even in the mid-to-low-end market segment, consumers' demands for screen quality continue to rise, compelling manufacturers to invest more in and innovate on screen technology to meet these demands.
Looking ahead, with further development and optimization of screen technology, we have reason to believe that the visual experience of smartphone screens will reach new heights, whether it's in high-end flagships or mid-range and budget products.
