A capacitive touch screen is a common input device that is often used in electronic devices such as smartphones, tablets, and computer monitors. How to protect the capacitive touch screen so that it can work continuously and efficiently is very important for users. How to protect the capacitive touch screen will be discussed below from the following aspects.

1. Clean the capacitive touch screen

When using capacitive touch screens every day, fingers or other objects can leave impurities such as dirt, grease and dust on the screen. These impurities may affect the sensitivity and use effect of the touch screen. Therefore, everyone needs to clean the capacitive touch screen regularly.

The correct way to clean the capacitive touch screen is to use a special cleaner or a clean damp cloth to gently wipe the surface of the screen, especially where there are many debris. Make sure the cleaning cloth is very clean to prevent the cleaner from penetrating into the screen. Touch the inside of the screen or leave it plush. It is recommended to use special electronic equipment cleaners or water with mild detergent added. These cleaners do not contain corrosive substances such as acid and alkali, and will cause little damage to the touch screen. Avoid using alcohol, ammonia and other strong corrosive cleaning agents, which will cause damage to the screen and affect the service life of the screen.

2. Avoid prolonged exposure to sunlight

The working principle of the capacitive touch screen is to analyze the user's input signal by sensing the change of the electric field of the human body, so as to accurately judge the user's operation action. However, under direct sunlight, due to the influence of voltage and temperature, the sensing performance of the capacitive touch screen will be significantly reduced, and it is prone to insensitive operation or false touch. Therefore, prolonged exposure to sunlight should be avoided.

3. Keep ferromagnetic objects and sharp objects away from the touch screen

The working principle of the touch screen is to analyze the user's input signal by sensing the change of the electric field of the human body, so if there is a strong magnetic material nearby, it will interfere with the normal operation of the touch screen. The approach of sharp objects is also prone to scratches and injuries, and the damage to the touch screen is irreversible.

4. Avoid pressing the screen too much

Although today's capacitive touch screens are highly fault-tolerant, excessive pressing on the touch screen can also damage it. If the finger or other object puts more pressure on it, it will cause unnecessary damage to the capacitive touch screen and shorten the life of the screen.

5. Do not hit the touch screen with sharp objects

When using a capacitive touch screen, some users will slide their fingers, and many users with special input habits will also use fingernails or pens and other sharp objects to operate the touch screen. But this is very likely to cause damage to the touch screen. Ginkgo supports the function of drawing by hand, which means that it is decisive and convenient to use the stylus. It is recommended that users who habitually use a stylus choose a pen with a thicker size from a stationery store as much as possible to reduce scratches and wear on the touch screen.

To sum up, it is very important to protect the capacitive touch screen, but how to protect and clean your own equipment can be built according to your own needs. Users can properly choose protection methods according to the actual situation, so that the capacitive touch screen can work more efficiently and permanently.
