Domestic and foreign countries have already had relatively reliable data support for blue light hazards. From 2013 to 2014, the visual health laboratory of China National Institute of Standardization conducted a study on the effect of LED blue light on human visual fatigue. Nearly 600 human visual physiology experiments showed that shielding 15% of blue light is better than non-shielding of blue light. The visual fatigue of the testers was nearly 21% lower.
In 2014, the China National Institute of Standardization's Visual Health Laboratory conducted a special cell molecular experiment on the retinal damage of blue LED light sources. The experimental results show that 400-440nm blue light below 500lx illumination for more than 2 hours, there will be significantly decreased cell viability or even apoptosis; 460-500nm blue light more than 1500lx illumination continues for more than 3 hours, will appear significantly decreased cell viability And apoptosis.
It can be seen that the damage of short-wave blue light to the eyes has been scientifically proven. The short-wave blue light emitted by TV LED screens is concentrated in the range of 447.5nm-450nm, which is characterized by high energy and strong penetrating power. It is the most important cause of our eyesight.
How to prevent the blue light from this band has become a common concern for consumers and TV manufacturers. The general approach is to have a "eye-safe mode" in the smart TV system. This method is simple and easy, and the consumer is also relatively easy to operate. Just enter the system settings and open the “eye protection mode†option. At present, almost all smart TVs have integrated this function.
The eye protection mode belongs to a type of software anti-blue light. The principle is to use a specific software algorithm to adjust the blue light in the RGB three-color channel to low flux to reduce the screen brightness and achieve high light, high contrast and high chroma. The image is corrected while suppressing the emission of short-wave blue light and long-wave blue light.
The eye protection mode has a low anti-blue ratio and can only filter out 30% of blue light, and it will cause the screen to color cast and affect the image quality. This is the best way to prevent Blu-ray before there is no more effective technology. However, on June 6th this year, Coolcam launched three Blu-ray education televisions, which used hardware-based anti-Blu-ray technology and changed the software's anti-blue light. Anti-Blu-ray rate is higher, and will not affect the screen image quality, a successful alternative to eye protection mode, become the best choice for scientific anti-blue light.
The principle of cool-opening optical anti-blue light is to transfer 450 nm short-wave blue light to 460 nm long-wave blue light and reduce 80-90% short-wave blue light damage by means of a blue-blue LED chip. It seems that the principle of cool optical blue light is relatively simple, but the technical implementation is not easy. For a long time, LED screen light emission, wavelength of 447.5nm-450nm has not been reduced, it is the LED screen light has a strong demand for blue LED, when the screen brightness is higher, the greater the amount of blue light, in order to make the TV screen more Bright, many manufacturers will increase the amount of blue light.
From the principle of software anti-blue light and cool optical anti-blue light, it can be seen that the essential difference between the two is whether or not to block blue light from the root. Anti-Blu-ray software, like adding a layer of lens to the screen, while filtering the blue light, also affected the image display. Cool open optical anti-blue light is to start from the origin of blue light, treat harmful blue light and harmless blue light differently, and when it can effectively prevent harmful blue light, it does not stop harmless blue light, so that the screen can display images normally.
Obviously, the advantage of cool open optical anti-Blu-ray technology is even more obvious. After all, when we watch TV, we don't want the picture to be distorted. Although software anti-Blu-ray can block 30% of Blu-ray, protecting our eyes to some extent, but contrary to our desire to pursue high-definition picture quality, we hope that The screen can truly restore the color of the image. Cool open optical anti-blue light can meet our needs.
At present, there are 3 products that use the cool open optical anti-Blu-ray technology television, including 55A3, 55U3B, 50U3B, and the order price is 4999 yuan, 3999 yuan, 3299 yuan. Cool open official website, Jingdong Mall, Lynx Mall, Suning Tesco, Gome Online are available for sale, coincides with the 618 big promotion, all models have great value concessions.
