Abstract
Abstract Apparatus for producing an interlaced scan of a matrix of discrete elements. The elements are arranged in vertical columns and horizontal rows, coincidentally addressed by vertical and horizontal ring counters. The horizontal address connections are divided into two groups, for the right half and left half of the display. Each left-half line is connected to a vertically displaced right-half line and the vertical ring counter is incremented at the beginning and at the center of each line scan, which produces an interlaced scan. During retrace intervals the ring counters step without connecting scanning elements, and additional logic circuitry produces standard blanking and synchronizing pulse signals.
