What is the ripple on the indoor led display?
The ripples we see are actually called "moiré patterns". When we shoot the scene with a digital camera, if there is a dense texture, inexplicable water wave-like stripes often appear, which is the moiré pattern. Simply put, moiré is a manifestation of the beat principle. Mathematically, when two equal-amplitude sine waves with close frequencies are superimposed, the amplitude of the resulting signal will vary according to the difference between the two frequencies.

Why does the indoor LED display have ripples?
1. The Indoor LED video billboard is divided into two types: high-brush and general-brush. The refresh rate of high-brush indoor LED display can reach 3840Hz/s, and the general-brush is 1920Hz/s. When playing videos and pictures, the high-brush and normal-brush screens are almost indistinguishable with the naked eye, but they can be distinguished through mobile phones and high-definition cameras.
2. When taking a photo with a mobile phone, there will be obvious water ripples on the indoor LED display of general brushing, and the screen looks flickering, while the screen with high brushing will not have water ripples.
3. If the requirements are not high or there is no shooting requirement, you can use the general brush, the difference between the naked eyes is not big, the effect is ok, and the price is also affordable. The price of high brush and general brush is quite different, and the specific choice depends on customer needs and capital budget.
