detailed description

In order to make the purpose, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

First, the blue light in the light emitted from the display screen will be described. Visible light acts on the human eye in two aspects: light radiation and heat generation, and different wavelengths of light have different effects on the human eye. Studies have shown that compared with other colors (wavelengths), blue light with a wavelength between 400nm and 500nm is the most harmful to the human eye, and it is likely to cause more obvious discomfort and disability than other long-wave green and red lights. glare. The human eye lens system does not sharply focus on blue light. Unlike red and green light that can be precisely focused on the retina, blue light is focused slightly in front of the retina. Moreover, blue is more focused than other colors. The spread is wider as it passes through the eyeball.

Studies have further shown that too much light radiation can cause damage to the retina, depending on the wavelength, intensity and length of exposure of the light. Blue light belongs to high-energy light in visible light. It easily passes through the cornea and lens and touches the retina, accelerating the oxidation of cells in the macular area of the retina. Excessive exposure can even damage visual cells. If the macular area is exposed to blue light for a long time, it will increase the risk of macular degeneration in the eyes in old age, and may even cause permanent vision damage. Therefore, blue light is more likely to affect the retina. In addition, in a darker environment, the human eye will be more sensitive to blue light, that is, the Purkinje shift. When watching TV or using a computer at night, when the surrounding light is very low, the human eye enters the state of intermediate vision, and the sensitivity spectral response curve is cheaper to the short wave, and is more sensitive to blue light. Excessive blue light will not only affect the health of the human eye, but also Stimulates the formation of melatonin.

Based on the foregoing, an embodiment of the present invention provides a display processing method applied to a terminal and the terminal, so as to reduce damage to human eyes caused by a display screen of the terminal.
