Grayscale on 1-bit LCDs (2022)
My father Bryce Bayer studied this question fifty years ago at Eastman Kodak; his approach is known as ordered dithering:https://en.wikipedia.org/wiki/Ordered_ditheringOne is effectively posterizing a grayscale image, and his primary goal was to reduce artifacts drawing unwanted attention to the borders between poster levels.With improvements in hardware other approaches to dithering took over. The last time I saw my father's pattern was on a DEC box logo. He moved to the color group at Kodak, and designed the "Bayer filter" used in digital cameras.
