How is LED water ripple generated?p10 led video wall

　　Firstly, we understand the concept of water ripple. The professional name of water ripple is Moore's ripple, which refers to the continuous flashing and jumping of horizontal bars when shooting at a low brush LED screen using various camera devices such as mobile phones. We all know that among the parameters of LED display screens, a very important parameter is the refresh rate, which to some extent also affects the price of LED screens, The refresh rate refers to the number of times per second that an LED display screen repeatedly displays the displayed Huaselong, in hertz (Hz). Nowadays, LED displays have low refresh rates and high refresh rates, with mainstream ones including 1920Hz, 2880Hz, 3840Hz, etc. The higher the refresh rate, the more frequent the frequency. Low refresh rate LED screens may exhibit water ripples when captured with a mobile phone or camera, appearing as if the screen is flickering. However, high refresh rate LED screens do not exhibit this phenomenon. The display screen is more delicate, with vivid and realistic colors, which can better restore the color of the screen.

　　In fact, the main root cause of solving the problem of water ripples lies in the selection of LED display screen refresh rate. If you want to completely solve this problem, choosing high refresh rate products when choosing LED display screen products in the early stage can fundamentally solve this problem. Of course, high refresh rate LED display screens are a bit more expensive than regular brushes, after all, you get what you pay for.
