ABSTRACT:
Disclosed is a flat panel display control apparatus which has the same number of dots as those of a CRT display device in the vertical and horizontal directions, has compatibility with the CRT display device, and displays each character by a plurality of dots in a matrix form. The flat panel display control apparatus has a video memory for storing character codes of characters to be displayed, a pattern generator for generating a character pattern corresponding to the character code generated from the video memory, an attribute data memory for storing attribute data for each character stored in the video memory, and an attribute controller for reading out the character pattern and the attribute data thereof so as to superimpose on the character pattern a lateral stripe pattern which repeatedly moves downward in a dot matrix constituting the character pattern when the attribute data indicates a high-light level of high-brightness display.
