Novel protector against electromagnetic radiation of display

Abstract

The invention discloses a novel protector against electromagnetic radiation of a display. The protector is composed of a glass container, a transparent electrolyte, transparent electro-conductive glass, a functional body, a metal pedestal and a grounding lead; a front plane is in parallel with a back plane of the glass container; the transparent electrolyte is positioned in the glass container; the transparent electro-conductive glass is positioned in the frontmost end of the protector, and the surface of the transparent electro-conductive glass is coated with a conductive film; the functional body of a flat cuboid structure is placed under the external plane of the glass container; the metal pedestal is placed in the bottom portions of the glass container, the transparent electro-conductive glass and the functional body, and is used to fix a structural body of the functional body; and a conductive layer of the transparent electro-conductive glass, the metal pedestal and an external grounding wire are connected with the grounding wire. When electromagnetic radiation of a screen of a visual terminal passes the structural body, most energy of electromagnetic waves is offset or converted, and protection against electromagnetic radiation is realized.

Description

technical field [0001] The invention relates to the fields of materials, electromagnetism, computer applications, etc., and in particular relates to a novel display electromagnetic radiation protection device. Background technique [0002] In recent years, with the popularization of mobile communication and computer applications and network technology, electromagnetic pollution caused by electromagnetic waves has become more and more serious, and is listed as the fourth largest environmental pollution after water, air and noise. Among them, computers, TVs, etc. The electromagnetic radiation, especially the high-frequency electromagnetic radiation, of the display screen of the video terminal is the most harmful to people's health. [0003] Electromagnetic radiation usually produces biological effects on the body through thermal effects, non-thermal effects and cumulative effects. From the analysis of the biological mechanism of radio frequency electromagnetic radiation, unde...

Problems solved by technology

[0007] First, transparent conductive film technology, high-frequency electromagnetic waves induce high-frequency eddy currents in the conductive layer of conductive glass, and the eddy currents can generate reverse electromagnetic fields, thereby offsetting part of the energy of incident electromagnetic waves and achieving the purpose of shielding electromagnetic radiation, but this method only To offset part of the energy of high-frequency electromagnetic waves, the protective effect is extremely limited for liquid crystal displays; secondly, the electromagnetic wave protection card technology uses a variety of rare metals and special materials that can absorb electromagnetic waves, and adopts special processes to produce certain electromagnetic waves. The electromagnetic protection card of absorption and energy conversion, this method can only absorb and weaken the electromagnetic wave radiation in a small area of ​​the plane area centered on the card, and cannot completely absorb the electromagnetic wave passing through a certain space area. Larger-area LCD screens, such as large-size LCD color TVs, have very limited effects, and cannot effectively monitor high-energy rays such as blue light radiation and ultraviolet rays in LCD screens, especially LED LCD screens that are more and more widely used. protection
