OPERATION DESCRIPTION
DISPLAY DATA TRANSFER
When DIO1 (or DIO2) pulse is loaded into internal latch on the rising edge of CLK2, DIO1 (or DIO2) pulse
enables the data transfer operation. After the falling edge of DIO1 (or DIO2), display data is valid on the rising
edge of CLK2. Once all the data of 300 / 309 channels are loaded into internal latch, it goes into stand-by state
automatically, and any new data is not accepted even though CLK2 is provided until next DIO1 (or DIO2)
input. When next DIO1 (or DIO2) is provided, new display data is valid on the next rising edge of CLK2 after
the falling edge of DIO1 (or DIO2).
EXTENSION OF OUTPUT
Output pin can be adjusted to an extended screen by cascade connection.
(1) SHL = "L"
Connect DIO1 pin of previous stage to the DIO2 pin of next stage and all the input pins
except DIO1 and DIO2 are connected together in each device.
(2) SHL = "H"
Connect DIO2 pin of previous stage to the DIO1 pin of next stage and all the input pins
except DIO2 and DIO1 are connected together in each device.
RELATIONSHIP BETWEEN INPUT DATA VALUE AND OUTPUT VOLTAGE
The LCD drive output voltages are determined by the input data and 18 (9-by-2) gamma corrected power
supplies (VGMA1 - VGMA18). Besides, to be able to deal with dot-line inversion when mounted on a single-
side, gradation voltages with different polarity can be output to the odd number output pins and the even
number output pins. Among 9-by-2 gamma corrected voltages, input gray-scale voltages of the same polarity
with respect to the common voltage, for the respective 9 gamma corrected voltages of VGMA1 - VGMA9 and
VGMA10 - VGMA18
