Abstract
PURPOSE: To increase display capacity without causing a flicker by displaying a character in a double-dot pattern by a CRT display unit, and by reproducing it on an interlacing system.
CONSTITUTION: In character generator 3, graphic patterns of characters, symbols, etc., to be displayed are all stored in the form of double dots. To display four characters HWK on one line, initial addresses (h)W(k) in character generator 3 are read out and entered into one-line code memory 1, and a display start signal is supplied to selective indicator 5, which sends an output of "1" to line address counter 2. Then, the counter provides even-number counting operation like 0, 2... and pattern codes of even numbers of characters HWK from character generator 3 are PS-converted into video signals, which are transferred to CRT; and a line address counter provides sequential odd-number counting operation like 1, 3... to read pattern codes of odd lines, which are displayed.
