Abstract

PURPOSE: To display data correctly by detecting the number of display dots of display data, and expanding the data corresponding to the difference of both numbers of display dots when the above-mentioned number is less than that of display dots in one prescribed direction on a display.
CONSTITUTION: The number of display dots in one prescribed direction is detected by counting the number of dot clocks DCK by the detecting part of a counter, etc., and lateral display size to be comprised is judged in advance based on a detection signal Sd. When display size is less than the lateral display size on a plane display 8, an expansion display control signal S'c is generated so as to set the difference between both display size at zero at an expansion display control part 2, and it is inputted to a data size driver 6. Thereby, the driver 6 can display the data of a character and a graphic on the entire display screen of the plane display 8 correctly based on an expansion control signal Sc.
