What should I do if there are water ripples on the display screen of OPPO mobile phone computer?

In some organic light-emitting diode displays, the brightness level is achieved by controlling the light-emitting time of pixels by PWM. The bright screen of the display screen is refreshed at a certain frequency, and the refreshing time is very short, which is beyond the range of human perception and cannot be detected by human eyes.

Images on TV/computer/mobile phone screens (not LCD) are scanned frame by frame by electron beams. Because the scanning speed is relatively fast, people's vision has a short stay, so our eyes see a complete picture. When shooting with a camera, the display refresh rate is about 60~85, and the camera shutter speed is about 50. When shooting high-frequency scenes such as screen pixels, the camera reaches the resolution limit of the camera photosensitive element, and the actual visual effect will see stripes or spots, which is a common optical phenomenon in the camera. This kind of ripple is also called ripple. I suggest you adjust the shooting angle, which will improve obviously.

Twill and water ripple will appear when shooting screen/projection, which is a normal phenomenon and does not affect normal use. You can reduce flicker in the following ways:

1. When shooting an OLED screen, you can choose to turn the brightness of the other screen to the maximum and take photos.

2. When shooting the organic light-emitting diode picture of the mobile phone, you can turn on the screen anti-flicker switch in the eye protection mode of the other mobile phone to reduce the screen flicker.

3. If you only need to get the contents of the mobile phone screen, you can directly use the screenshot function that comes with the mobile phone.
