Why do you have electronic stripes when you shoot a computer screen with a mobile phone?

1, because the screen refresh frequency is lower than the shutter speed of the mobile phone, it will be generated. The refresh frequency is what we often call the Hertz (hz) of the screen. You can try to lower the refresh rate and improve it slightly. Generally, the refresh frequency is 60HZ, which is imperceptible to human eyes, but can be captured by the mobile phone camera.

2. The different refresh frequency between mobile phone and computer is an important reason for the stripes on the computer. The refresh frequency actually refers to the number of times a computer or mobile phone refreshes per second, although from the naked eye, there is no difference in their refresh times.

3. First of all, when a mobile phone shoots a computer screen, it will produce electronic ripples because the screen refresh frequency is lower than the shutter speed of the mobile phone. Secondly, the refresh frequency is what we often call the Hertz of the screen.
