Display controller and display device including the same

A display device comprising:

• a display panel, the display panel having a display resolution corresponding to a first directional total pixel number of the display panel multiplied by a second directional total pixel number;
• and
• a display controller configured to control the display panel, the display panel comprising:
• a graphics memory having a storage capacity defined by the first directional size multiplied by the second directional size;
• a graphic memory controller configured to,
• convert two-dimensional (2-D) addresses to one-dimensional (1-D) addresses based on an input clock signal and the first directional total pixel number,
• convert the 1D addresses to physical 2D addresses based on the first directional size, and
• control the graphic memory to store input data based on the physical 2-D addresses;
• and
• a scan controller configured to,
• increase scan addresses one line by one line for displaying the input data stored in the graphic memory according to the display resolution, and
• control the graphic memory to output the stored input data to the display panel such that the stored input data is displayed on the display panel.
