Screen
The display memory of the S1D13700 may be used as a virtual screen of greater width than the physical size
of the LCD panel address range (C/R). One layer of the S1D13700 may be considered a window through
which to look at the part of display memory that comprises a virtual screen. This window can be divided into
two blocks that may correspond to independent areas on the virtual screen. Therefore, it is possible to use one
block as a dynamically scrollable data area and the other as a stationary message area. (See Figures 4-7 and 4-
8.)
