Abstract

A selection circuit is connected between a display composed of unit picture elements arranged in a dot matrix and a vertical scanning circuit, the selection circuit effects the selection of odd or even lines in the display. The advantages offered by such an arrangement are elimination of the necessity of interlaced scanning in the scanning circuit itself, cutting the number of steps in half in the scanning circuit during interlaced scanning, increase in the margin in operating speed and elimination of limitations on circuit configuration, device construction and materials used.
