Elimination of LED display water ripple failure method

I often hear people asking us why the LED display is very clear when watching it on the spot, but after taking it with a mobile phone or camera, it is found that the display screen in the photo has something like water ripples on the screen, making the whole screen very clear. Blurred, this will make customers very worried about the quality of the LED screen. So how to deal with this phenomenon?



How to eliminate the water ripple failure of the LED display screen:



1. Change the camera angle. Since the angle of the camera shooting object will cause water ripples, slightly changing the camera angle, by rotating the camera, you can eliminate or change any ripples that exist.



2. Change the camera position. In addition, by moving left and right or up and down to change the angle relationship, water ripples can be reduced.



3. Change the focus. Too sharp focus and high detail may cause water ripples. Changing the focus slightly can change the sharpness and help eliminate water ripples.



4. Change the focal length of the lens. Different lens or focal length settings can be used to change or eliminate water ripples.



5. Use the front filter to install directly in front of the CCD to make the exposure conditions meet the spatial frequency, thoroughly filter the high spatial frequency part of the image, reduce the chance of water ripples on the display screen, but it will also reduce the image simultaneously Sharpness.
