This article reports a research method of LCD moiré based on Fast Fourier Transform (FFT). We use programmable software to build a complete moiré simulation model, and established an evaluation system. This method has been verified to have high accuracy in moiré simulation, and because it is based on image processing, the moiré results can be quickly obtained, thus the design efficiency can be greatly improved.
