Usually, the service life of capacitive touch screen is relatively long, but the specific life will be affected by a variety of factors. Generally speaking, the service life of capacitive touch screen can reach several years under normal use and proper maintenance. Some data show that capacitive screen can support charging about 30,000 times under normal circumstances, or support more than 100,000 times of click operation. In addition, after mechanical testing, its service life can even be as long as 30 years. However, this does not mean that all capacitive touch screen can achieve this life, because the actual use of the environment, the way of use and other factors will have an impact on the life.
Factors affecting the service life of capacitive touch screen
1. Use of the environment and conditions:
- Temperature: Both high and low temperatures will negatively affect the life of capacitive touch screen. Prolonged use in extreme temperatures will accelerate the aging process of capacitive screen and reduce its service life.
- Humidity: Excessive humidity may lead to moisture in the internal circuitry of the capacitive screen, affecting its performance and life.
- Dust and dirt: Prolonged periods of time without cleaning can lead to the accumulation of dirt, affecting the sensitivity and accuracy of touch.
2. Usage:
- Tapping and pressure: Excessive tapping, scratching the screen violently or using hard objects to knock will cause damage to the capacitive screen and shorten its service life.
- Frequency and intensity of touch: high-frequency, high-intensity touch operations will also accelerate the wear and tear of the capacitive screen.
3. Product quality and manufacturing process:
Different brands and models of capacitive touch screen in the quality and manufacturing process differences, which will also affect its service life. High-quality, high-standard manufacturing process can enhance the durability and stability of capacitive touch screen.
4. External factors:
- Liquid infiltration: Liquid infiltration into the capacitive screen will lead to unstable voltage, which will cause damage to the capacitive screen.
- Strong magnetic field: Strong magnetic field will affect the performance and life of capacitive screen, so capacitive touch screen devices should be avoided to be placed near the strong magnetic field.
The normal life of the touch screen in different application environments and routine maintenance methods will vary depending on a variety of factors such as the environment in which it is used, the frequency of use, product quality and maintenance. The following is an analysis of the service life of some common application areas:
The normal life of different application environments
1. industrial control:
Normal life: high-quality industrial touch screen in the case of normal use and proper maintenance, its service life can reach more than 5 years, and even in some cases can be used for 10 years or more. This depends mainly on the durability of the product, the level of protection and the environment in which it is used.
Influencing factors: high temperature, high humidity, corrosive gases or environments with more particles may shorten its service life.
2. Financial display terminals:
Normal life: Since financial terminals need to run stably for a long time and require high security and reliability, the life of their touch screens is usually longer, depending on product design and use and maintenance.
Influencing factors: long-time power-up, high-frequency operation of users and dustproof and waterproof ability will affect its life.
3. outdoor advertising touch screen:
Normal life: the outdoor environment is complex and changeable, the touch screen temperature resistance, waterproof, drop resistance and other performance requirements are high. Therefore, its life is relatively short, but high-quality outdoor touch screen can also have a long service life under reasonable maintenance.
Influencing factors: extreme weather, ultraviolet radiation, wind and sand erosion will accelerate its aging process.
4. Smart home applications:
Normal life: the life of the touch screen in the smart home is affected by the frequency of use and product design, generally speaking, under normal use and maintenance, its life can reach several years.
Influencing factors: the humidity and temperature of the use of the environment and the user's operating habits will affect its life.
The routine maintenance methods
1. Regular cleaning: use a clean microfibre cloth or special screen cleaner to wipe the surface of the touch screen to remove dirt and fingerprints. Avoid the use of chemical cleaners containing alcohol, ketones or acids, so as not to damage the outer coating of the touch screen. If the touchscreen is not easily removable, make sure to clean it after powering down.
Benefits: Removing dirt and fingerprints can maintain the clarity and sensitivity of the touch screen, avoiding touch insensitivity or misoperation due to the accumulation of dust and dirt.
2. Dust and waterproof: For touchscreens that need to be dust and waterproof, such as industrial controls and outdoor applications, the seals should be checked regularly to make sure they are intact and to avoid water and dust from entering the interior. Install a dust cover or perform additional dust protection measures to extend the service life.
Benefits: Ensuring that the inside of the touch screen is protected from water and dust can effectively extend its service life and prevent failures due to internal short circuits or corrosion.
3. Avoid physical damage: Avoid touching the touch screen with sharp or hard objects to avoid scratching or damaging the surface. Place the device in a safe location to prevent collisions or accidental drops.
Benefits: The touch screen is a fragile part, avoiding touching with sharp or hard objects can prevent scratching or damaging the surface and reduce maintenance costs.
4. Use a protective case or film: In cases where additional protection is required, consider using a protective case or film to reduce the impact of external shocks and scratches on the touch screen.
Benefits: Providing additional protection for the touch screen can reduce the impact of external shocks and scratches on the touch screen and extend its service life.
