/PRCWT/Beijing, August 23, 2023——Recently, BOE Yiyun launched a new eye care technology - natural light display technology, which uses unique scattered particles to change the polarization state of light, breaking through the LCD screen can only spread the characteristics of line polarized light, to achieve unpolarized natural light display, so that the screen light closer to natural light. Make the viewer visual experience more comfortable, eye protection effect more obvious.
Linearly polarized light, circular polarized light, are not as good as natural light
At present, the main "natural light" eye care products on the market, mostly using linear polarized light, circular polarized light technology. Linear polarized light energy distribution is concentrated, strong, strong stimulation of the eye, circular polarized light, although upgraded on the basis of online polarized light, the eye stimulation is reduced, but still belongs to the regular change of polarized light, easy to cause eye fatigue. Both can not achieve uniform eye protection effect, long-term use has potential risks, may lead to the fovea macula area of the fundus intense stimulation, damage to retinal cells, prone to a series of eye problems, such as eye acid, eye stinging, tear rupture, eye conjunctival congestion. In a state of unstable tear film and persistent visual fatigue, the risk of myopia may be further increased.
Before the appearance of artificial light source, the natural light in nature is the only light source in the living environment, the human eye is an organ that evolved from photoreceptor cells under natural light, for the human eye, natural light is a comfortable and ideal light source, is random non-polarized light, its light spreads in all directions, with the dynamic change of light, the pupil of the human will continue to shrink and expand. Drive the ciliary muscle and other parts to be adjusted accordingly, can avoid eye axis growth too fast, alleviate eye fatigue, delay the development of myopia.
As a new generation of Natural Light technology innovated and developed by BOE Art Cloud, the natural light display technology converts the linearly polarized light emitted by the LCD screen into unpolarized natural light through the polarization dispersion particle YNF(Yiyun Natural Light Film) technology of a specific structure, achieving uniform dispersion of the polarization direction of the whole band. Consistent with the original non-polarized light characteristics of nature, the emitted light is dispersed in all directions, and the light energy is evenly distributed, which is not easy to produce eye stimulation for a relatively long time. At the same time, the natural non-polarization rate of natural light display technology has reached the highest level in the industry of 92%, while the traditional way can only reach 60% to 70%. The higher the natural non-polarization rate, the closer to natural light, in a certain sense, the natural light display technology breakthrough to create a soft and comfortable light environment like natural light.
Professional authority research: natural light display technology can significantly reduce visual fatigue and dry eye symptoms
In May 2023, the Eye Hospital of Zhejiang University conducted a test on the impact of natural light display technology on human eyes, and conducted a 2-hour movie viewing study on 46 adolescent subjects. Among the 18 subjective and objective indicators of eye fatigue and dry eye symptoms, 13/18 indicators (about 72% of indicators) of teenagers showed significant increases after using linearly polarized light tablet to watch movies. The use of natural light display technology tablet viewing only 2/18(only 11%) indicators increased. According to this, Zhejiang University Eye Hospital released the "Research Report on the impact of different polarized light plates on the eye symptoms of adolescents and children", the report pointed out that the screen equipped with natural light display technology is more comfortable and soft than the traditional linear polarized light LCD screen, which can greatly protect the stability of the eye surface tear film and reduce the damage to the macular area of the eye ground. It is very suitable for children and teenagers to learn and use.
It is worth mentioning that natural light display technology has formed two unique practical invention patents, formed intellectual property protection for the industry-leading natural non-polarization technology, and was recognized by the Chinese children Myopia Prevention and control White Paper (2023), which is highly influential in the industry.
As a new generation of exclusive light processing technology, natural light display technology breaks professional barriers, creates a health display closer to natural light, and strengthens the line of defense of screen "vision protection". It is reported that BOE Art Cloud will introduce this technology in subsequent new products, and continue to improve the eye-care "index" of the screen through healthier display technology.
