A capacitive touch screen is a common input device that is often used in electronic devices such as smartphones, tablets, and computer monitors. Next, let's understand what problems will arise when using a capacitive touch screen:

1.Inaccurate operation/touch: 

Due to its high sensitivity, a capacitive touchscreen may be susceptible to unintended input or mistakes, resulting in unexpected outcomes or inaccurate operation.

2.Multi-finger touch issue: 

Capacitive touchscreens usually support multi-finger touch, but there may be instances where multi-touch operations fail or result in unintended actions.

3.Response delay issue:

 Due to slow touchscreen response or insufficient system processing power, a capacitive touchscreen may experience response delay or lag.

4.Cleaning issue:

 Capacitive touchscreens require regular cleaning to maintain their performance. If not cleaned properly, their sensitivity may be affected, and the likelihood of inaccurate operation may increase.

5.Damage issue: 

Due to the fragility of the touchscreen, or in cases of strong impacts, a capacitive touchscreen may be damaged, affecting its functional performance.
 

6.Compatibility issue:

 Due to the technological characteristics of capacitive touchscreens, compatibility issues with certain operating systems or software can arise, affecting the overall user experience of the device.
