① Avoid scratching the LCD screen of outdoor highlight advertising machine by hard objects. Some of the surface of the LCD screen has a protective film, and some of it doesn't. The color LCD screen without a protective film is very fragile, and any scratch will leave traces. You can use a special protective sticker for the LCD screen, which has a certain effect on protecting the LCD screen.

② It is necessary to avoid the surface of the LCD screen of outdoor highlight advertising machine being squeezed by heavy objects, and at the same time avoid the damage of high temperature to the LCD screen. As the temperature rises, the LCD screen will turn black. After reaching a certain temperature, even if the temperature drops back to the normal state, the LCD screen cannot be restored. However, the brightness of some LCD screens will decrease with the decrease of temperature. When the temperature is quite low, the brightness of LCD screens will be very low. Once the temperature rises, the brightness will automatically return to normal, which is a normal phenomenon.

Matters needing attention when cleaning:

First of all, never use soft cloth or paper towel such as glasses cloth to wipe the LCD screen. This is easy to scratch the LCD screen. For dust, we can first blow it off by blowing, and the remaining dust particles can be gently wiped on the LCD panel with a special LCD wiping cloth. For fingerprints and oil stains, there is a special liquid crystal wiping cloth.

Secondly, you can't clean the LCD screen with water, alcohol or some chemical solvents. Because of the use of clean water, liquid can easily penetrate into the LCD screen or digital camera, which is very easy to cause short circuit of equipment circuits.

Alcohol is a commonly used organic solvent, which can dissolve some dirt that is not easy to wipe off. If it is occasionally used to clean the shell of digital cameras, it may have no adverse effects. But don't use alcohol to clean the LCD screen. Once alcohol is used to wipe the display screen, this special coating will be dissolved.

If the screen is accidentally stained with stains that are not easy to remove, such as juice or coffee, don't use alcohol to wipe it, because it is easy to wipe off the stains and scrap the LCD screen. Experts suggest that you can spray a proper amount of deionized water with a special wiping cloth for LCD, and then gently wipe it, so that the stains will not be traced and the LCD screen will not be scratched.
