5. Function Description
DATA SHEET V04
5.1 Device operation
In the condition of L/R=H, the STV1 start pulse input is sensed at the rising edge of
CPV and stored in the first stage of shift register, which causes the first scan signal is
outputted from the OUT1 output pin. While stored data is transferred to the next stage
shift register at the rising edge of next CPV, new data of STV1 is sensed and stored
simultaneously.
The output pin (OUT1 to OUT240) supplies VGH voltage or VEE voltage to the LCD
panel depending on the data stored in the shift register. For normal operation, a VGH
voltage is outputted one by one from OUT1 to OUT240 in sync with CPV pulse.
After 240 CPV rising edge are past, the STV2 goes up to high level at the 240th
falling edge of CPV and goes down to low level at the 241th falling edge of CPV. This
STV2 output signal becomes the STV1 start pulse input of next cascaded gate driver
device.
During any H state of OE, the corresponding output channels are forced to VEE
regardless of CPV. The channel output returns to normal status as soon as OE goes
back to L.
During any L state of /XAO, all the output channels are forced to VGH regardless of
CPV and OE. The channel output returns to normal status as soon as /XAO goes
back to H.
