Liquid crystal is a special substance between solid and liquid. It is an organic compound that is liquid under normal conditions, but its molecular arrangement is very regular like solid crystals. Therefore, it is named liquid crystal. It is another special The nature is that if an electric field is applied to the liquid crystal, its molecular arrangement will be changed. At this time, if it is matched with a polarizer, it has the effect of preventing light from passing through. Nowadays, LCD screens can be seen everywhere in life, such as laptops, LCD TVs, mobile phones, SLR cameras, etc. Nowadays LCD screens have become a must-have electronic product for many people. So what are the taboos when using LCD screens? The following editor Zhilingxin will introduce to you.
What are the contraindications when using the LCD screen:
1. Moisture invasion
Moisture can be said to be the first natural enemy of liquid crystals. The destructive power of water on the LCD screen is amazing. Therefore, the LCD screen should be used in a relatively dry environment to prevent moisture from entering the inside of the LCD screen. For some users who work in a humid environment, you can buy some desiccant to keep the air around the LCD dry.
2, dust attack
Like CRT, LCD is very easy to get dust.
3. Hard object attack
LCD is relatively soft and easily damaged (except for glass screen outside). So be careful not to touch the screen with hard objects when using it.
4. Long-term use
Because LCD is not simple, its pixels are constructed by many liquid crystals, and continuous use for a long time will cause the crystal to age or burn out. Once the damage occurs, it is permanent and irreparable. So it's better not to use it for a long time. Now many users' computers are online. For the convenience of pictures, they often turn off the monitor at different times after shutting down, which will seriously damage the life of the monitor.
5. Improper handling
The liquid crystal display is very delicate, and the quality of the display and the internal liquid crystal molecules of the display may be damaged during the process of violent movement or vibration, which greatly reduces the display effect. In addition, avoid strong shocks and vibrations. The LCD screen contains many glass and sensitive electrical components. Falling on the floor or other similar strong blows can cause damage to the screen or other units. This point must be paid attention to during the transportation, try to put on thick armor for the liquid crystal, and then carry it.
