Abstract

PURPOSE: To compensate the printing quality easily and satisfactorily by storing a letter pattern and a brightness code in a memory thereby to compensate the brightness of the printing display of a CRT.
CONSTITUTION: In response to the command signals from a processor, the dot pattern, which is stored in a pattern memory for forming a letter, and the brightness code signals, which correspond to the complexness of the letter, are read out to control a deflecting circuit 40 and a brightness control circuit 60 through a control circuit 30 so that the printing letter pattern of a preset brightness is displayed in a CRT 70. As a result, in accordance with the complexness of the letter composed of equi-distantly spaced dots, the brightness is compensated and displayed so that the printing quality can be compensated easily and satisfactorily.
