This commands changes the mapping between the display data column address and segment
driver. It allows flexibility in layout during LCD module assembly. Refer to
Figure 5.
This command forces the entire display to be illuminated regardless of the contents of the
GDDRAM. This command has priority than the “Set Normal/Reverse Display” but lower priority
than the “Set Display On/Off” command.
This command sets the display to be either normal/reverse. In reverse display, a RAM data of
‘0’ indicates an “ON” pixel while in normal display; a RAM data of ‘0’ indicates an “OFF” pixel.
This command has lower priority than both “Set Display On/Off” and
On/Off”.
This command is to force the chip to enter Sleep Mode. The internal oscillator and LCD power
supply will be turn off when enter to such mode.
After POR, the internal oscillator is OFF. It should be turned ON by sending this command to
the chip.
This command is used to turn the display on or off, by the value of the LSB. It has the highest
priority over other commands regarding the display effect.
This command positions the page address of 0 to 21 possible positions in GDDRAM. Refer to
Figure 5. During 16-bits write operation, the last bit of the page address is ignored, D0-D7
always writes to even page and D8-D15 always writes to odd address.
