Abstract

PURPOSE: To display easily readable letters by making new letter signals by obtaining "OR" signal of the letter signal and the delay signal which has delayed letter signals, elongating dots in the scan direction and strengthening the connection between dots adjacent in the diagonal direction.
CONSTITUTION: With the letter signal producing system that displays letters on CRT 6 in dot pattern having been scanned by providing display memory 1, character generater 3, timing control circuit 2 and parallel serial conversion circuit 4, serial dot signal f from circuit 4 is applied to one of the inputs of OR circuit 8 as well as delay elment 7 and, then, dot signal g that has been delayed by delay element 7 is applied to the other input of circuit 8. Dot signal f and delayed dot signal g are processed through "OR" circuit 8 to newly produced dot signal h and, then, dot signal h is applied to CRT 6 through luminance modulation circuit 5, thus strengthening the connection between diagonally adjacent dots and displaying letter more clearly.
