Problems solved by technology

[0002] In modern life, TVs and computers have been widely used. When people use TVs and computers, they often need to face the display screen for a long time, especially when using computers, they must face the computer at close range. The picture tube of the display screen inevitably produces radiation such as electromagnetic waves and static rays, so it has adverse effects on the health of users; and the ordinary display screen is coated with organic phosphate, which will be released when the display screen is heated. Triphenyl phosphate may cause allergic symptoms such as itchy skin, nasal congestion, and headaches to users; in addition, due to the electrostatic radiation effect of ordinary display screens, it is easier for dust in the air to adsorb on its surface and become dirty. , so frequent cleaning is required
In order to solve these problems, there is also a protective screen installed outside the display screen to block radiation and block dust, but this method cannot completely block radiation and block dust, and it will make the displayed image unclear and affect TV, TV, etc. appearance of computer
