Eye-protective display screen

Abstract

The invention discloses an eye-protective display screen and belongs to the technical field of display. The eye-protective display screen comprises a flat display screen body (1), an intrados or inner spherical surface optical fiber image guide screen body (2), nanometer color (3), transparent wear-resisting paint (4) and a powerful non-stretch adhesive tape (5), wherein the nanometer color (3) is mixed with the transparent wear-resisting paint (4), the mixture is sprayed on the intrados or the inner spherical surface of the intrados or inner spherical surface optical fiber image guide screen body (2), and the flat display screen body (1) and the intrados or inner spherical surface optical fiber image guide screen body (2) are adhered together by the powerful non-stretch adhesive tape (5). The eye-protective display screen has the advantages that the eye-protective display screen with a visual sense like color printing is wider in color gamut and lower in color temperature than an original display screen and is capable of eliminating visual fatigue, thereby playing a role in protecting eyes of children and people watching the display screen for a long time.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular provides an eye-protecting display screen, which is suitable for schools, TV stations and other places, and has very wide applications. technical background [0002] Although light pollution is rarely mentioned, it not only has a great impact on eyesight, but also has great damage to the body. The effect of light on eye vision depends on the wavelength, intensity and irradiation time of light. It is generally known that ultraviolet rays are harmful to the human body, but for the eyes, except for high-energy blue light, ultraviolet rays, infrared rays and other colors of light are all harmful. Can be absorbed by the cornea and lens, only blue light will pass through the cornea and lens to directly contact the retina. Blue light has a strong stimulating effect on the retina. In medicine, blue light is often used to irradiate the eyes of children to stimulate the retina to treat ...

AI Technical Summary

Problems solved by technology

Color printing technology can provide nearly perfect colors through space color mixing technology, and its color reproduction can almost reach the level of fictitiousness, but no matter what kind of display it is, its color expression is much different than that of color printing. Differences, such as: LCD TVs are relatively poor in expressiveness for orange, and laser TVs are relatively poor in blue expressiveness, etc.
