Claim:
A display device for displaying character data and image data, both generated by application software, comprising: a data storage unit configured to store the character data and image data, both processed in an absolute coordinate system by the application software; a display unit configured to display the data stored in the data storage unit; and a control unit configured to control the writing of the data from the application software into the data storage unit and reading the data from the data storage unit into the display unit, wherein the control unit controls the writing of first data from the application software into the data storage unit, while copying each one-pixel data item at magnification N in a vertical direction and magnification M in a horizontal direction, and the writing of second data into the data storage unit, without the second data being magnified at all, wherein the display unit displays the first data and the second data simultaneously at different resolutions when the display unit has resolutions of N×K and M×L pixels in the vertical direction and the horizontal direction, respectively, and the application software processes the data in a K×L absolute coordinate system.
