The more display devices you use, the greater the strain on your eyes. And the larger the screen size, the heavier the visual burden! As some netizens point out, it’s nearly impossible to "escape" screens these days—whether scrolling on phones, watching TV, gaming on computers, working in offices, attending classes, or even walking down the street. Beyond essential work and life needs, much of our screen exposure is passive and unavoidable.
According to the *China Internet Audiovisual Development Research Report (2024)* released on March 27, 2024, the average daily mobile internet usage per person in China reached 435 minutes by December 2023. QuestMobile data shows that Douyin (TikTok’s Chinese counterpart) users spent an average of 46.54 hours per month on the platform—translating to over 1.55 hours daily. On October 31, 2024, China’s National Bureau of Statistics published its third national time-use survey, revealing that the average daily sleep time for residents was 9 hours and 46 minutes, work-related activities took up 3 hours and 28 minutes, and internet usage averaged 5 hours and 37 minutes.
In summary, screen time has become the second-largest daily activity for Chinese residents, surpassed only by sleep.
Against this backdrop of pervasive and prolonged screen exposure, eye-friendly display technology is emerging as the next frontier in the industry. Health is poised to become the most critical competitive differentiator, following advancements in display performance and larger screen sizes. The display, lighting, and optometry industries are now racing to innovate around "health-first" upgrades.
The Next Phase of Healthy Display Technology
In May, display giant AOC partnered with BOE to launch the AOC EyeLove Circular Polarization Gaming Monitor Q27G4SL/WS. Traditional linear polarization technology emits light vibrating in a single direction, which overstimulates specific areas of the eye, leading to prolonged ciliary muscle tension and symptoms like dryness and fatigue. BOE’s circular polarization solution, however, features a specialized eye-care layer that mimics natural light by rotating light vectors uniformly. This distributes stimulation evenly across the eye, reducing strain on the lens and retina for a more comfortable viewing experience.
At June’s Mobile World Congress (MWC) Shanghai, TCL CSOT unveiled the world’s first Quasi-Natural Light Spectrum tablet display, earning SGS’s inaugural certification in this category. By optimizing backlight units (BLUs) and RGB color filters, the product replicates sunlight’s full-spectrum composition to regulate circadian rhythms: boosting dopamine secretion (which helps prevent myopia) during daytime and minimizing melatonin suppression at night. In SGS testing, TCL CSOT’s display achieved a 56% QNLI score—a metric comparing its 380-780nm visible light overlap with natural noon sunlight.
On June 9, NationStar showcased "healthy lighting" innovations at the Guangzhou International Lighting Exhibition. Highlights included:
- Expanded-spectrum lights incorporating infrared and violet wavelengths.
- Elderly-friendly lighting with low-blue/high-red designs to accommodate age-related vision decline.
- Dynamic smart lighting that mimics daylight (enhancing alertness) by day and shifts to warm tones (promoting sleep) at night.
Technologies like circular polarization, natural-light simulation, and red-spectrum enhancement represent the next wave of healthy display innovation—building on past progress in flicker reduction, blue-light mitigation, and color accuracy.
The Ultimate Evolution: Displays That Respect Human Vision
The science behind spectrum-enhanced displays isn’t new. As early as 2010, Sharp introduced four-color LCD panels using RGB+Yellow subpixels to deliver more natural, eye-friendly colors.
Yet displays face a unique challenge: unlike lighting, they can’t freely mimic sunlight’s continuous spectrum. Their color output must align with the human eye’s red, green, and blue photoreceptors. While precise RGB wavelengths deliver vivid, wide-gamut images, they create three spectral peaks—far from sunlight’s smooth curve.
This mismatch disrupts our evolutionarily ingrained circadian rhythms. Displays’ artificial spectra are a key reason they strain eyes more than natural environments.
The industry’s holy grail? Simulating sunlight’s continuity without sacrificing color performance—a dilemma akin to "having your cake and eating it too." Solutions will require breakthroughs surpassing earlier innovations like polarization, ambient-light adaptation, or anti-glare tech.
Light impacts more than vision: it affects ocular biology, systemic health, and sleep cycles. For instance, enriching displays with deep-red wavelengths (akin to sunlight) can improve ocular microcirculation. Truly healthy displays must balance image quality with photobiological harmony.
Experts caution against oversimplifying screen-time risks: while total light exposure hasn’t spiked with digitalization, the unnatural spectra of displays and older LED/fluorescent lighting are the real culprits. For example, pre-2010 high-blue LEDs (5-10x stronger than sunlight in critical wavelengths) were later linked to macular degeneration.
Health-Conscious Innovation: What Consumers Demand
Eggshell Research estimates China’s optometry market grew from $100 billion (710B RMB) in 2015 to $170 billion (1.21T RMB) in 2022 (8.5% CAGR)—paralleling the mobile internet boom. Meanwhile, eye health issues surged: 700 million with refractive errors, 360 million with dry eye, and 52.7% myopia among youth in 2020.
Healthier displays aren’t just a tech upgrade—they’re a societal imperative. At April’s inaugural *2025 Visual Ergonomics & Health Standardization Conference* in Beijing, China National Institute of Standardization VP Dai Xinhua stressed that visual health is now a public priority. Work began on a comprehensive standard system covering R&D, testing, and certification—including metrics to quantify displays’ impact on comfort and health.
"Future TVs and phones will carry ‘visual ergonomics ratings’ alongside energy labels," predicts one expert. Such grading could safeguard public health while spurring innovation.
Far from a marketing gimmick, "healthy vision" is a foundational challenge for displays—akin to overcoming flicker and blue light in the past. As digitalization engulfs lives globally, the industry must champion technologies that protect billions of eyes. The future of displays lies in clarity, comfort, and sustainability—a future where tech truly sees eye-to-eye with human wellbeing.
