According to reports, blue light is a high-energy visible light with a wavelength of 400-500 nm. Harmonic short-wave blue light has extremely high energy, and excessive exposure can damage the visual cells, and this damage is irreversible. Blue light damages the eyes in three ways. Excessive blue light causes the retinal pigment epithelial cells to shrink or even die. It damages the structure of the eye. It can lead to deeper myopia or diplopia, causing visual fatigue. Excessive blue light can inhibit the secretion of melatonin. Affect sleep quality.
Territt's inspection data shows that the radiance value of Skyworth OLED TV measurement is 0.1441W•m-2•sr-1, which is far below the 100 W•m-2•sr-1 non-hazardous level standard. Terent Lighting Engineers said that due to the pixel self-luminous independent, no LED backlight characteristics, and the OLED TV blue light band is mainly concentrated in the 460nm, not in the harmful wavelength range, so the blue light energy is very small, for the human eye The harm is negligible and negligible.
In addition to the Blu-ray detection of OLED TVs, the company also conducted comparative analysis with LCD TVs, LCD monitors, and mobile phones through Tairuite Big Data.
Big data show that the average brightness of LCD TV is 0.6339W•m-2•sr-1, and the average Blu-ray of 4,5-inch mobile phone screen is 0. 434W•m-2•sr-1, while the 55-inch OLED TV has blue radiation. The amount is only 1/3 of this value.
However, there has always been a lot of talk about the blue light in electronic devices causing harm to human eyes. Just as many people in the LED industry talk about Blu-ray harm, they generally say that Blu-ray is harmful, but it is not that the LED will damage the human eye, but it is more likely to be said.
However, despite this, it is critical that Territor engineers warn consumers that proper use is achievable by avoiding blue light as a health hazard.
First of all, the eye structure of children and adolescents is still growing up, and it is necessary to pay attention to the irreversible damage to the eyes caused by television blue light under certain circumstances. Second, adults should pay attention to watching distance and duration. Harmful Blu-ray damage to the eyes is cumulative, so it is better to see the screen from 30 cm to 40 cm (TV distance is 5-7 times the diagonal line), take a break every 20 minutes for 20 seconds, watching distance.
Finally, quit the habit of watching TV, playing with mobile phones or tablets before going to bed. Most families choose to watch TV at night before going to bed, or even turn off the lights. Plus, splash screens and other factors cause harmful blue light to damage the eyes. Blu-ray damage will inhibit the secretion of melatonin, resulting in poor sleep quality and even difficulty falling asleep.
