In today’s world where display technology is deeply integrated into daily life, visual health has become a global focus. On July 16, 2025, the second Health Display Conference was grandly held in Beijing under the theme of “Standards Leading, Eye Protection for the Long Term.” Representatives from industry associations, research institutions, and leading enterprises gathered to discuss the collaborative development path of display technology and visual health.
As a global leader in the LCD display field, BOE attracted significant attention at this conference. Mr. Wang Kaixuan, Director of the LCD Product Development Center, delivered a keynote speech titled “Healthy Eye Protection Display Technology,” systematically elaborating on BOE’s innovative achievements and strategic layout in the field of eye protection technology, which resonated widely within the industry.
The Vision Challenges of the Display Era and BOE’s Technical Depth
From mobile phone screens to in-car displays, from office computers to home televisions, display devices have become the “infrastructure” of modern life. However, traditional displays pose visual health risks in four aspects: harmful blue light can penetrate the retina and cause macular degeneration by generating free radicals; screen flicker (below 3000Hz) can lead to vision decline and even negatively affect the brain; significant differences between ambient light and screen brightness can cause frequent adjustments of the pupil and ciliary muscle, leading to eye fatigue; glare can cause short-term muscle tension in the eyes and long-term viewing can lead to vision deterioration.
In response to these challenges, BOE has focused on “simulating natural light” as the technical starting point and has been deeply engaged in the eye protection field for many years. As the world’s largest LCD panel supplier, BOE has continuously delved into low blue light control, polarization light optimization, and dynamic light adaptation, forming a complete technical system from basic principles to product applications. Through collaborative innovation with ophthalmic institutions and industry partners, BOE has not only promoted the establishment of health display standards but has also transformed technology into a perceivable product experience, making “eye protection” practical rather than just a concept.
Natural Light Display Technology: BOE’s Systematic Eye Protection Innovation
Wang Kaixuan emphasized in his speech that the core of natural light display technology is to “replicate the physical characteristics of natural light”—natural light has the characteristics of a complete and balanced spectrum, soft and uniform light, continuous and stable light intensity, and random vibration direction. BOE approaches this ideal state through four major technical dimensions.
Spectral optimization is the foundation of natural light display. Traditional screens concentrate blue light in the 415-455nm wavelength range. BOE uses the “LED wavelength red shift + CF color resistance compensation” technology to reduce the proportion of harmful blue light while avoiding yellowing of the image, which is superior to software filtering or blue light blocking film solutions. The more advanced CRHD (Circadian Rhythm Health Display) technology employs a dual-wavelength LED backlight design that dynamically adjusts the blue light ratio according to the time: increasing the rhythmic blue light ratio during the day to suppress melatonin and enhance focus; reducing the blue light ratio at night to promote melatonin secretion and aid sleep, achieving natural regulation of physiological rhythms. Additionally, BOE innovatively integrates infrared light into the backlight, utilizing its photobiological effects to achieve active eye protection and eye repair, while full-spectrum technology simulates the continuous spectrum of natural light, allowing the three types of cone cells in the retina to evenly share photon energy, fundamentally reducing visual fatigue.
Light shape optimization addresses the “unnatural” issue of light distribution. Glare from traditional screens often originates from ambient light reflection. BOE employs ultra-low reflection technology, using multi-layer anti-reflective films and high-resistance films to reduce panel reflectivity to below 1%, far lower than the industry average of 3-5%. This ensures clear images even in bright environments. Paper-like technology increases the half-peak width of the brightness curve through multi-layer diffusion processing, making light distribution as soft as paper, especially suitable for long reading scenarios.
Time-varying control technology allows screen light to adapt to environmental changes. High refresh rate technology (such as 120Hz, 144Hz) reduces brightness differences between frames, combined with DC modulation (adjusting current rather than pulse control for brightness), completely eliminating the flicker problem of traditional PWM dimming. BOE’s mainstream products have fully adopted this technology. The integrated light-sensing sensor technology further breaks the limitations of traditional external solutions by embedding the sensor inside the screen, adapting to ambient light in real-time through proprietary algorithms, saving space in the device and tripling the response speed of brightness adjustment, thus avoiding visual stimulation from flickering light.
Vibration control technology addresses the “unnatural” characteristics of polarized light. Traditional linear polarized light can only allow a portion of lutein to filter blue light. BOE’s circular polarization technology (BSF solution) achieves over 85% circular polarization conversion efficiency, allowing more lutein to participate in filtering, thus reducing blue light damage to the retina. Tests from Beijing Tongren Hospital show that this technology significantly reduces blinking frequency and enhances eye comfort. Random depolarization technology further reduces visual load by incorporating calcite crystals into the OCA glue, allowing the light’s vibration direction to be randomly distributed, making it closer to the isotropy of natural light.
Full-Scene Implementation: An Eye Protection Ecosystem from Technology to Product
BOE’s natural light display technology is no longer a laboratory achievement but has been implemented across a full range of products, including televisions, monitors, and learning devices, through deep collaboration with global partners, creating an eye protection ecosystem that covers various life scenarios.
In family scenarios, Skyworth G7F Pro ultra-black wide-angle paper-like screen television is set to be the industry benchmark product of 2025, equipped with the ultra-black wide-angle paper-like screen Pro technology co-developed with BOE. This screen reduces reflectivity to 0.7% (industry average 1.8%) through three core technologies: LR low reflection layer, STW full-view compensation layer, and AG anti-glare layer, and dynamically adjusts the harmful blue light peak wavelength to below 454nm, reducing blue light hazards by 60% compared to traditional OLED televisions. Actual measurements show that children’s eye fatigue index decreases by 40% after watching for 2 hours, and it has received the S++ certification for visual health friendliness from the National Quality Certification Center. Its 1152-zone Mini LED backlight system, combined with dynamic BFI algorithms, achieves a peak brightness of 1500nits while avoiding color distortion caused by software filtering through hardware-level low blue light technology, truly realizing a breakthrough in “eye protection without color distortion.”
In the commercial display field,
Lenovo’s UHD Mini LED monitor adopts BOE’s glass-based active driving technology, achieving ultra-fine light control through 1152 backlight zones. Its natural light display mode can automatically adjust grayscale according to ambient light, restoring a paper-like reading quality and effectively alleviating visual fatigue during long hours of work.
AOC’s eye protection circular polarized gaming monitor Q27G4SL/WS employs BOE’s circular polarization technology, optimizing color performance while reducing glare. Its hardware-level low blue light mode and intelligent brightness adjustment function make it the preferred device for industries with strict visual health requirements, such as finance and healthcare, and it has also received the TÜV Rheinland Global Eye Protection 3.0 certification.
The education sector is a key application area for eye protection technology. BOE’s small class screen E3 is equipped with a 21.5-inch paper-like eye protection screen, utilizing lossless gamma display patented technology to accurately restore 256 grayscale levels, making the screen display effect close to that of paper books. Its 10-layer optical design effectively reduces reflections and has received TÜV low blue light certification, with a hardware-level blue light filtering ratio of 35%. Additionally, the product includes an electronic vision chart and eye usage duration reminder function, constructing a full-cycle eye protection system from hardware to software.
BOE’s Healthy Vision Learning Screen addresses the needs for myopia prevention and control among adolescents, utilizing AR free-form surface technology to simulate the viewing effect of 10 meters away at a distance of 40-50cm, alleviating ciliary muscle tension by changing the viewing distance, allowing for eye protection while using the screen.
The implementation of these products is backed by BOE’s close collaboration with the upstream and downstream industry chain—from co-developing dual-wavelength LEDs with backlight module manufacturers to jointly optimizing light-sensing algorithms with terminal brands, and involving ophthalmic institutions in technical validation, forming a closed loop of “technology research and development – product implementation – clinical validation” that truly serves users.
In Conclusion:
From the technical details disclosed at the Health Display Conference to the application products that permeate life scenarios, BOE’s natural light display technology redefines the relationship between “display and health.” It is no longer simply about “reducing harm” but about harmonizing screen light with the human visual system by simulating the essential characteristics of natural light. This root-based technological innovation not only reflects BOE’s technical strength as an industry leader but also highlights its industrial responsibility of “technology for good.” Through deep collaboration with the upstream and downstream of the industry chain, BOE is transforming eye protection technology into tangible product experiences, making the era of “display everywhere” truly realize “health everywhere.”
