With the development of digital society, electronic products such as mobile phones, tablets, and computers have become an indispensable part of people's lives. While enjoying the wonderful world brought by the screen, eye health is becoming a topic of focus. June 6, 2024 is the 29th National "Eye Care Day". On this special day, BOE (BOE Technology Group Co., Ltd.) takes technological innovation and green development as its concept, and uses full-scenario eye protection technologies such as low blue light, ultra-high frequency PWM dimming, oxide LTPO, Tandem, and low-power green technology to enable technology to empower diversified innovative applications and smart terminals, creating display solutions with perfect picture quality, healthy eye protection, and immersive boundless, leading industry standards with innovative technology, and brightening the windows of the soul for thousands of users, protecting the beautiful "visual" world.

All-scenario eye protection technology demonstrates pioneering strength

By deeply cultivating and researching the field of eye care, BOE (BOE Technology Group Co., Ltd.) combines technology with eye care, is committed to protecting eye health through technological innovation, and actively develops industry-leading eye care technologies. Many of its technologies have achieved major breakthroughs in the industry.

Among visible light, harmful blue light emitted by electronic devices is currently a major cause of harm to eye health. In response to the blue light problem, BOE (BOE Technology Group Co., Ltd.) uses LED backlight peak red shift technology and OLED device blue light peak red shift technology to effectively filter harmful blue light in the 415nm~455nm band, greatly reducing the proportion of harmful blue light generated by the screen to less than 6%, which is far lower than the industry reference level. Compared with other technologies, BOE (BOE Technology Group Co., Ltd.)'s flexible OLED low blue light technology can not only achieve low blue light within the full color temperature and reduce damage to the eyes, but also maintain excellent display quality, no color cast, no color gamut reduction, and restore the realistic colors of the display.

Under natural light, BOE's independently developed ADS Pro high-end LCD display solution has excellent performance. The human eye needs a certain ambient light brightness when using display devices, otherwise it is easy to cause eye soreness and tears. Ambient light contrast refers to the contrast of display devices tested under common indoor lighting, and the surface reflectivity of the display screen is the key factor affecting the ambient light contrast. UB Cell, a typical representative of the ADS Pro solution, reduces the surface reflectivity of the display from the conventional 5% to 1.1% through a variety of anti-reflection technologies, including surface treatment, pixel structure optimization, and the development of a variety of new materials in the liquid crystal box, greatly improving the comfort of the human eye when using display devices under natural light.

In a dim environment, the flickering of the screen may stimulate the eye muscles to move and cause eye discomfort. The low-risk PWM dimming flickering frequency should be at least 1250 Hz. To address the flickering problem, BOE uses the industry's first ultra-high frequency PWM dimming technology, with a dimming frequency of up to 4320Hz, far exceeding the human eye's perception of flickering. Even when using a mobile phone in a dimmed environment, it can minimize the harm of flickering to the eyes.

BOE's second-generation dynamic lossless Gamma display technology has two invention patents (patent number ZL 2016 10214546.6 and patent number ZL 2019 1 0389905.5), which makes the display clear in different ambient light. By using the patented paper-like eye protection technology to accurately restore 256 different degrees of "gray" between black and white, the electronic screen can achieve a paper-like original texture. At the same time, the grayscale is accurately adjusted according to the ambient light, and the visual comfort is improved with more accurate and layered colors, making the screen as easy and real as reading a book.

In addition, BOE has also launched a series of optical technologies to protect healthy close-up eye use. By adding scattering particles, the natural light display technology developed by BOE can convert the linearly polarized light emitted by the LCD into uniformly scattered non-polarized light, making the screen light softer and reducing visual fatigue and dry eye symptoms; free-form surface optical technology can achieve high-definition imaging from 3 to 10 meters away to 60 to 140 inches without changing the physical distance, greatly increasing the eye distance and further protecting the user's vision health.

Technology empowers terminals to protect eye health in all aspects

In addition to making breakthroughs in technology, BOE is also committed to the implementation and transformation of technology, enabling advanced eye protection technology to empower global first-tier brand terminal devices and provide users with a full range of eye protection experience. In life scenarios, BOE and Skyworth jointly launched the world's first Skyworth Mingli Screen® Smart Mini LED TV Q27 using active glass-based technology. It uses active constant current drive to effectively reduce flicker, while maintaining a stable and smooth picture, while relieving long-term visual fatigue, allowing eye protection to be integrated into life in a pleasing way; Honor Magic 6 RSR Porsche Design mobile phone is equipped with BOE LTPO+Tandem technology and 4320Hz ultra-high frequency PWM dimming mode, which greatly reduces the potential harm of the screen to the eyes in a dark environment, allowing users to experience healthy play at night. Office scenes are also related to "screens" everywhere. The Lenovo UHD Mini LED display equipped with BOE (BOE) glass-based active drive technology has a 31.5-inch large screen and 1152 independent backlight partitions, which can achieve ultra-fine light control and effectively avoid the damage to the eyes caused by the instantaneous ultra-high brightness and screen flickering of passive drive. There is also the ROG Strix 8 Plus Super Competitive Edition for smart eye protection in the entertainment field, equipped with high-frequency PWM dimming technology and hardware low blue light technology. Through BOE ADS Pro empowerment, it can achieve a 60-240Hz dynamic frequency modulation refresh rate and 3ms ultra-fast response, bringing users an unimaginable eye protection visual experience.

BOE (BOE Oriental Technology Group) pays more attention to the extension of technology and develops a series of eye protection products and solutions to make eye protection technology serve more consumers. Represented by Yiyun Technology, a subsidiary of BOE (BOE Oriental Technology Group), the BOE Small Class Screen A1S released by Yiyun Technology is equipped with an H629 natural light screen. It has been clinically certified by Beijing Tongren Hospital and can effectively reduce visual fatigue by 24%. The built-in family vision chart can match the detection method according to different scenarios, and establish a dedicated vision file for users for easy management. It has obtained the EYE GUARD A+ International Gold Label Eye Protection Certification issued by SGS; BOE Painting Screen E2 uses paper-like eye protection display technology, which can achieve low blue light and no flicker. It also has functions such as reminders for eye use time, vision detection at any time, and popularization of eye knowledge, which protects children's eye health in online classes in all aspects. The smart medical and engineering business field also launched the BOE Healthy Vision Learning Screen independently developed based on eye protection and health. It uses AR free-form surface technology to simulate telescope, allowing children to watch large-screen images 10 meters away from a distance when they are 40~50cm away from the screen, effectively avoiding close-up eye use.

As an industry leader, BOE has taken the lead in formulating the first authoritative healthy eye protection standard in China's semiconductor display field in the field of eye protection technology, and has worked with TÜV Rheinland to fully define the eye protection capabilities of display screens from three dimensions: eye protection technology, dynamic display characteristics, and ambient light management. BOE has also established a long-term strategic partnership with TÜV Rheinland and has carried out a series of cooperation in the field of screen eye protection and performance. At present, BOE's flexible OLED screen has passed the low blue light certification of authoritative organizations such as TÜV Rheinland and SGS.
