An accurate and fast moiré pattern analysis algorithm is proposed for a periodic metallic array placed adjacent to a patterned red-green-blue (RGB) light source with a microscopic gap utilizing Fourier transform along with the human eye contrast sensitivity function. We analyzed how the moiré pattern evolved varying tilt angles and metal array periodicities placed on the top of RGB light sources, which have their own spatial periodicities. Based on multiplicative model, moiré patterns were numerically generated and the influences of 70 tilt angles and 60 periodicities on the moiré standard deviation were thoroughly analyzed to minimize moiré visibility. Our numerical results were compared to a prior analytical approach to obtain a good agreement, and the proposed scheme can be further applied to larger scale display systems with sophisticated touch screen metal arrays.
针对一种周期性金属阵列，提出了一种精确且快速的莫尔条纹图案分析算法。该金属阵列与具有微观间隙的图案化红绿蓝（RGB）光源相邻放置，利用傅里叶变换以及人眼对比度敏感函数进行分析。我们分析了放置在具有自身空间周期性的RGB光源顶部的莫尔条纹图案如何随着倾斜角度和金属阵列周期的变化而演变。基于乘法模型，通过数值生成莫尔条纹图案，并深入分析了70个倾斜角度和60个周期对莫尔条纹标准偏差的影响，以最小化莫尔条纹的可见度。将我们的数值结果与先前的分析方法进行比较，以获得良好的一致性，并且所提出的方案可以进一步应用于具有复杂触摸屏金属阵列的更大规模显示系统。
