Danger of too bright screen: When people look at the screen, they all hope that the higher the brightness, the better, making the picture more gorgeous and the details better. In order to attract consumers' attention, large-scale home appliance stores often decorate the environment with bright lights, and the brightness of many flat-panel TVs is also adjusted very high by shopping guides.
In the market environment, compared with the bright and dazzling LCD TV screen, the original soft and harmonious picture of plasma is dim and colorful. So many people think that the higher the screen brightness, the better.
But in fact, the products with 500 lumens brightness and 600: 1 or above contrast can fully meet the viewing needs. Excessive pursuit of brightness not only increases the power consumption of TV, but also causes eye fatigue, which is not conducive to eye protection.
According to the doctor, one of the hazards of TV to human body is all kinds of strong light and reflected light, because improper brightness is easy to cause eye fatigue, even harmful to eye health, leading to eye fatigue, myopia, astigmatism, cataract and so on. This is also a kind of light pollution. Relevant researchers also pointed out that when the brightness of the display screen reaches 1000cd/m2, it will cause symptoms such as visual fatigue, dry eyes and heavy eyelids, and even lead to health problems such as decreased vision and headache.
Because too strong light will consume a lot of rhodopsin, the photosensitive substance of retinal rod cells in the eye, it will cause temporary vision loss, which is more likely to lead to myopia for children who are still in the growth stage. Therefore, it is best to choose a flat-panel TV with soft and moderate brightness and a color closer to nature. There is really no need to blindly pursue too high brightness.
