Set Display Mode (A4h ~ A7h)
These are single byte command and they are used to set Normal Display, Entire Display On, Entire
Display Off and Inverse Display.
Set Entire Display On (A5h)
Forces the entire display to be at “GS63” regardless of the contents of the display data RAM.
Set Entire Display Off (A4h)
Forces the entire display to be at gray level “GS0” regardless of the contents of the display data
RAM.
Inverse Display (A7h)
The gray level of display data are swapped such that “GS0” <-> “GS63”, “GS1” <-> “GS62”, ….
Normal Display (A6h)
Reset the above effect and turn the data to ON at the corresponding gray level.
Master Configuration (ADh)
This command contains multiple bits to control several functionalities of the driver.
Select DC-DC converter (A[0])
0 = Disable selection of DC-DC converter and VCC is supplied externally.
1 (POR) = Enable selection of DC-DC converter to supply high voltage to VCC. The output
voltage of the converter is set by values of external resistors. Please refer to section “DC-DC
Voltage Converter” for details.
Select V
COMH
supply (A[1])
0 = Select external V
COMH
voltage from V
COMH
pin for the common waveform high voltage level
supply. It is recommended to set the voltage of V
COMH
such that the OLED pixel diode is not
turned on (prefer in reverse bias state) when the segment pin is either driven to V
PA
, V
PB
or V
PC
level.
1 = Select internal V
COMH
voltage generated by regulator from V
REF
. The level of V
COMH
can be
programmed by command BEh.
Select pre-charge voltage supply (A[2])
0 = Select pre-charge voltage sources from external pins V
PA
, V
PB
, V
PC
for color A, B and C
respectively.
1 = Select pre-charge voltage supply internally. The level of V
PA
, V
PB
, V
PC
can be set by
command BBh for color A, B and C respectively.
Set Sleep mode On/Off (AEh/AFh)
These single byte commands are used to turn the OLED panel display on or off. When the display is on,
the selected circuits by Set Master Configuration command will be turned on. When the display is off,
those circuits will be turned off and the segment and common output are in high impedance state.
Power Saving Mode (B0h)
This command sets the driver IC either in normal power mode and power saving mode.
Set Reset (Phase 1)/ Pre-charge (Phase 2) period (B1h)
This command sets the length of phase 1 and 2 of segment waveform of the driver.
Phase 1 (A[3:0]): Set the period from 1 to 16 in the unit of DCLKs. A larger capacitance of the
OLED pixel may require longer period to discharge the previous data charge completely.
Phase 2 (A[7:4]): Set the period from 1 to 16 in the unit of DCLKs. A longer period is needed to
charge up a larger capacitance of the OLED pixel to the target voltage V
PA
, V
PB
, V
PC
for color A, B
and C respectively.
