Abstract

PURPOSE: To reduce the amount of data to be transferred from a control part and to reduce load by providing a dummy data setting circuit at the input circuit of a picture display device to write arbitrary character data to a RAM for display.
CONSTITUTION: The dummy data setting circuit 13 is built in the input circuit so as to write the character data to the RAM 5 for display, and one bit is added to the data of a display control register circuit. Therefore, in respect to picture display for displaying the plural same characters between the certain characters, the dummy data setting circuit 13 can write the arbitrary character data to the address of the RAM 5 for display corresponding to the positions between those characters. As a result, when the plural arbitrary characters are continuously displayed at the time of data refresh, the data can be displayed on a screen without transferring the character data from a control part 1 since the data is provided in the picture display device itself. Thus, the amount of data to be transferred from the control part 1 can be reduced.
