Abstract
Official abstract text for this publication.
A display controller includes a graphic memory, a graphic memory control unit and a scan control unit. The graphic memory has a storage capacity defined by a first directional size multiplied by a second directional size. The graphic memory control unit converts two-dimensional (2-D) addresses to one-dimensional (1-D) addresses based on an input clock signal and first directional total pixel number of a display panel for displaying input data, converts the 1-D addresses to physical 2-D addresses based on the first directional size and controls the graphic memory to store the input data. The display panel has a resolution corresponding to the first directional total pixel number multiplied by a second directional total pixel number of the display panel. The scan control unit increases scan addresses one line by one line to display data stored in the graphic memory according to a display resolution.
