The display data is input with a width of 12 bits by double edge, viz., the gray scale
data (8 bits) by 3 dots (1 pixel).
These refer to the start pulse input/output pins when driver ICs are connected in
cascade. The shift directions of the shift registers are as follows.
R,/L = H (V
R,/L = L (V
R,/L = H (V
R,/L = L (V
R,/L = H (V
R,/L = L (V
Refers to the shift register’s shift clock input. The display data is incorporated into
the data register at both of rising and falling edge.
At the falling edge of the 160th clock after the start pulse input, the start pulse
output reaches the high level, thus becoming the start pulse of the next-level driver.
The contents of the data register are transferred to the latch circuit at the rising
edge. And the output timing and output short function are controlled by MODE1 to
MODE3. Please refer to 8. RELATIONSHIP BETWEEN STB, POL, MODE1 to
MODE3 AND OUTPUT WAVEFORM for more detail. It is necessary to ensure
input of one pulse per horizontal period.

Data inversion can invert when display data is loaded.
INV = H (V
INV = L (V
Please input DC signal. For details, refer to 6. DATA INVERSION.
LPC = L or open: Normal mode (default)
LPC = H: Low power mode (35% lower than noamal mode)
This pin is pulled down to the V
This pin controls the output short function.
Output short function works only when POL signal is changed from previous line.
