Abstract
PURPOSE: To ensure a distinct identification between the cursor display and other displays for the display unit which indicates the cursor display through blinking of one section, by giving the processing to the cursor through blinking with inverse to the blinking period.
CONSTITUTION: When the blinking designation is given, the video signals are cut with the clock cycle of 4Hz to give blinking to the characters. With the inversion designation given, the output of exclusive logic sum circuit 15 becomes 1. While in case no inversion designation given, the character signal is inverted through exclusive logic sum circuit 13 to be changed into the video signal. When the inversion designation is given, the inversion is given in the opposite cycle. And the blinking is given to the cursor in the opposite cycle to the blinking designation cycle. Thus the same pattern is not given to the cursor indication in any case, thus securing a distinct identification for the cursor display form other displays.
