Column/Row output
Description
Data shift clock.
The data is shifted to 80 bits shift register at the falling edge of ‘CP’ when used as column
driver.
Data load pulse.
When used as a column driver, a row of display data is latched at the falling edge of ‘LD’.
When used as a row driver, ‘LD’ is the shift clock input.
Series data input/output of column/row driver.
1). When ‘L/R’ = 1, ‘DIO1C’ and ‘DIO1R’ are series data inputs of column driver and row driver
respectively. ‘DIO2C’ and ‘DIO2R’ are series data outputs of column driver and row driver
respectively.
2). When ‘L/R’ = 0, ‘DIO2C’ and ‘DIO2R’ are series data inputs of column driver and row driver
respectively. ‘DIO1C’ and ‘DIO1R’ are series data outputs of column driver and row driver
respectively.
3). When ‘MODE1’⊕’Mode2’ = 0, ‘COL/ROW’ = 1, SPOD80A is used as dedicated column
driver, series data input of row driver, ‘DIO1R’ or ‘DIO2R’ depending on ‘L/R’, should be
connected to VSS or float.
4). When ‘MODE1’⊕’Mode2’ = 0, ‘COL/ROW’ = 0, SPOD80A is used as dedicated row driver,
series data input of column driver, ‘DIO1C’ or ‘DIO2C’ depending on ‘L/R’, should be
connected to VSS or float.
Column driver/Row driver selection
Power supply of digital circuit
GND of digital circuit
Power supply of OLED driving buffer
GND of OLED driving buffer
Selection of data shift direction
Mode selection. There are 12 modes can be selected when combine ‘MODE1’, ‘MODE2’ with
‘COL/ROW’ and ‘L/R’.
Selection of driving method, default is ‘H’.
CV = 1, current driving mode
CV = 0, voltage driving mode
This mode selection is valid when used as column driver only.
Brightness control input. By adjusting an external voltage (VBT) and resistor (RBT), the output
current in O[1:80] can be adjusted, see function description. This adjustment is valid when
used as column driver and CV = 1 only.
Internal/external resistor selection.
Connect this pin to ground while using internal resistor, or float it when using external resistor
