Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :

从产能规划对比看，本次扩产的节奏显得颇为激进。民德电子在调研会上表示，广芯微一期项目规划为6英寸硅基功率器件月产10万片，截至2025年年底，一期实际产能仅为4万片/月，仍处于典型的产能爬坡阶段，距离满产仍有较大差距。
