The lifespan of a capacitive touchscreen varies based on many factors. Here are some factors that can affect the lifespan of a capacitive touchscreen:

1. Material quality: The material quality of a capacitive touch screen is very important. If low-quality materials are used, the lifespan of the touchscreen may be shortened.

2. Physical damage: Physical damage to a capacitive touch screen will affect its lifespan. Especially during use, sparks, needlepoints, blades or other sharp objects are prone to scratch and hit the screen.

3. Long-term use: Long-term use will cause wear and aging of the touch screen. In addition, if you use it for a long time or use it continuously for several hours, it may cause the touch screen to be affected by high temperature, which may cause damage to the screen, so it is recommended to use it for an appropriate time every day.

4. As an input tool: Capacitive touch screens are usually used to input data and interact. If it is used frequently, its service life will be shortened accordingly.

5. Manufacturing and quality control: If there are problems in manufacturing and quality control, the life of the capacitive touch screen will be shortened accordingly.

Generally speaking, the service life of the capacitive touch screen can reach several years, usually it can be used for three to five years. In use, it is necessary to pay attention to strict keys, use of liquids, etc., and timely maintenance and cleaning. Good maintenance work to ensure the stability and reliability of the service life. For the long-term use of industrial equipment in enterprises or factories, special attention should be paid to the use of the touch screen to ensure accuracy and life.
