Cover board arrangement for visual window

Abstract

The invention comprises two window covering boards in same thickness. The microelement is added into the window covering boards in high temperature condition to increase its transparency; there is a conducting metal mesh between two window covering boards to shield electromagnetic wave.

Description

technical field [0001] The invention relates to a window cover device, in particular to a window cover device capable of shielding electromagnetic waves and preventing strong light from interfering with vision. Background technique [0002] At present, electrical appliances and electronic products sold in the market tend to be more and more high-performance and miniaturized. The displays for displaying information are sealed with window covers. The window covers of such electronic products are generally made of glass or quartz, usually The working surface of the window cover plate is not processed. The improvement is to add plastic polarizing film and glare film on both sides of the working surface of the window cover plate. [0003] The main purpose of this type of window cover is to display the display content of the display sealed inside the electronic instrument, and to seal and isolate the internal components of electrical appliances and electronic products from the out...

AI Technical Summary

Problems solved by technology

[0004] 1. For electrical appliances that require shielding of electromagnetic waves, the shell of electronic products is made of metal materials that can shield electromagnetic waves, and the window cover does not have the performance of shielding electromagnetic waves, so that electromagnetic waves and interference waves generated by other electrical appliances and electronic products can pass through such ordinary window covers The area where the board is located interferes with the normal operation of electrical and electronic products, causing electrical and electronic products to malfunction frequently and destroying other electronic devices inside the instrument, especially in terms of communication, causing great damage to the normal operation of the product

[0005] 2. Under medium-intensity light, such as indoor light sources or outdoor light during the day, because this type of window cover is affixed with plastic polarizing film and glare film on the inside and outside to weaken the reflection intensity, filter the light, and make the human eye The content displayed on the display can be clearly recognized visually, but under strong light, such as strong sunlight, gas lamps, neon lights, etc., the strong light reflected from the working surface of this type of window cover can still make people feel uncomfortable. The human eye cannot visually read and recognize the displayed content of the display. Even if the angle of view is adjusted or the position of electrical and electronic products is changed, the clarity of the displayed content of the display will deteriorate, making it impossible for the human eye to clearly read and recognize the displayed content of the display. content, and this kind of plastic polarizing film and glare film are not wear-resistant and easy to wear, which reduces the application effect of the window cover;

[0006] 3. The production cost of this type of window cover plate is high, and there are defects of uneconomical and low efficiency
