Abstract
The present invention relates to a method for frame memory access and a display driver using the same. The method is a data moving method for allowing a display driver integrated circuit built in a portrait style frame memory to be used in a landscape mode. The spirit of the method is to repeatedly read data from the portrait style frame memory to the shift register, and move the data on the shift register to put the data to the correct data latch to constitute complete scan line data. Therefore, the portrait style display driver integrated circuit may drive a landscape mode display panel.
