Computer foremen are divided into two groups. Some argue that touching the monitors is strictly prohibited, while others talk about the safety of such a touch. To answer this question? first you need to understand how modern monitors are arranged, and only then draw conclusions.
Most modern devices are LCD monitors. The principle of their work is very simple. The construction is made in layers. The bottom layer is the highlight. It is followed by a layer of liquid crystals. Further filters. The most delicate and capricious part of the device is the liquid crystal matrix. She does not tolerate shocks, falls, does not like temperature extremes. All this leads to the appearance of dead pixels or damage to certain areas of the screen.
Remember how some joked at school with calculator screens. They pressed the screen with a finger and looked at the divorces. If you press harder, a large black spot appears, which may disappear after removing the load, or it may remain on the display. Thus, the display will be damaged.
Now the answer to the question posed earlier seems obvious. It is better not to touch the LCD screen with your fingers. At the very least, this results in greasy streaks on the screen that are not easy to remove. In the worst case, an amateur poking his finger at the screen can damage the matrix and, accordingly, break an expensive monitor.
Technically speaking, if you touch the screen carefully, it will not damage the matrix. But those who like to poke their fingers at the screen with such force that multi-colored waves go, will surely sooner or later reach the LCD matrix and damage it.
Accordingly, if among your friends there is a fan of poking a finger, then it is better to wean him from this habit. You can touch the screen of a modern monitor with your hands only gently and gently, without pressing, and even more so without the appearance of rainbow waves. The screen can be cleaned with a soft cloth, but do not apply strong pressure. You could poke your finger on old monitors with a tube. Their protective glass made it possible to do this without the risk of damage.
