Embodiment Construction

[0009] The present invention will be further described below.

[0010] In the protective film for a display screen of the present invention, the thickness of the protective film is an integer multiple of the half-wavelength of blue light, and the protective film is made of PET material.

[0011] The working principle is: the surface of the display screen is coated with a multi-layer protective film, so that the electromagnetic waves of different wavelengths generated on the front and rear surfaces of the film layer interfere with each other, thereby offsetting the radiation and achieving the effect of radiation protection and radiation reduction. Blue light is an important part of visible light. When blue light is mixed with green light and yellow light, it presents white light. Green light and yellow light have less energy and less stimulation to the human body. Blue light has short wavelength and high energy. LEDs, computer backlights and artificial light sources retain a l...

Abstract

The invention relates to a display screen protective film and belongs to the technical field of radiation protection. The thickness of the protective film is integer times as much as that of a semi-wavelength of blue light; and the protective film adopts a PET (Polyethylene Terephthalate) material. The display screen protective film has the beneficial effects of simple process, low cost, energy saving and environmental friendliness, and strong radiation protection.

Description

technical field [0001] The invention relates to a protective film, in particular to a protective film for a display screen. Background technique [0002] With the development of society, computers have become an indispensable tool for work and study. People face computer screens for a long time, which can cause eye fatigue and even lead to myopia. The computer protective film currently sold on the market is mainly to prevent damage to the display screen, and does not have the function of radiation protection. In addition, most of these computer protective films are made of high molecular polymer films, which cause a series of problems such as energy consumption and environmental pollution. Therefore, it has become a development trend of the computer protective film industry to develop a radiation-proof computer protective film with simple process, low cost, energy saving and environmental protection. Contents of the invention [0003] In view of the above-mentioned exis...
