G09G3/2048 - CPC Classification

Classification description:

Control arrangements or circuits, of interest only in connection with visual indicators other than cathode-ray tubes for presentation of an assembly of a number of characters, e.g. a page, by composing the assembly by combination of individual elements arranged in a matrix no fixed position being assigned to or needed to be assigned to the individual characters or partial characters; Display of intermediate tones using dithering with addition of random noise to an image signal or to a gradation threshold
