DISPLAY DATA RAM
Figure 5
The display data RAM (DDRAM) stores pixel data for the LCD. It is a 43-row x
102-column addressable array. It is possible to access any required bit by specifying the
page address and the column address. The 43 rows are divided into 5 pages of 8 lines, 1
page with 2 line (D0,D1) and the seventh page with a single line (D0 only).
The each bit in the Display Data RAM corresponds to the each pixel of the LCD each
pixel of LCD panel. The each bit in the Display Data RAM corresponds to the each pixel
of the LCD panel and controls the display by following bit data.
When Normal Display : On="1" , Off="0"
When Inverse Display : On="0" , Off="1"
(Refer to “Inverse Display ON/OFF” instruction for more detail.)
