COMMAND DESCRIPTIONS

Set Column Address

This command specifies column start address and end address of the display data RAM. This command

also sets the column address pointer to column start address.

Set Row Address

This command specifies row start address and end address of the display data RAM. This command also

sets the row address pointer to row start address.

Set Contrast for Color A, B, C

This command is to set Contrast Setting of each color A, B and C. The chip has three contrast control

circuits for color A, B and C. Each contrast circuit has 256 contrast steps from 00H to FFH. The segment

output current increases linearly with the increase of contrast step.

Master Current Control

This command is to adjust the overall display brightness. The chip has 16 steps segment current

reduction. The range is form 1/16[0000] to 16/16[1111]. POR is no current reduction [1111].

Set Re-map

This command changes the mapping between the display data column address and segment driver, row

address and common driver. It allows flexibility in layout during OLED module assembly.

When A[5] is set as 0, COM outputs are in sequential format. When it is set as 1, COM outputs are in odd

and even mode. See COM layouts in Figure 1 and 2.

Set Data Format

This command allows user to set different data formats for 256 color (8-bit) and 65k color (16-bit).

Set Display Start Line

This command is to set Display Start Line register to determine starting address of display RAM to be

displayed by selecting a value from 0 to 63.

Set Display Offset

This is a double byte command. The next command specifies the mapping of display start line (it is

assumed that COM0 is the display start line, display start line register equals to 0) to one of COM0-63.

For example, to move the COM16 towards the COM0 direction for 16 lines, the 6-bit data in the second

command should be given by 0010000.

Set Display Mode

This command is used to set Normal Display, Entire Display On, Entire Display Off and Inverse Display.

Set Entire Display On forces the entire display to be at “GS63” regardless of the contents of the display

data RAM. Set Entire Display Off forces the entire display to be at gray level “GS0” regardless of the

contents of the display data RAM. Normal Display will turn the data to ON at the corresponding gray level.

Set Multiplex Ratio

This command switches default 1:64 multiplex mode to any multiplex mode from 16 to 64.

Set Display On/Off

This command turns the display on or off. When the display is off, the segment and common output are in

high impedance state.
