DETAILS OF PIN FUNCTIONS
STB (input)
Refers to the input pin of the row drive strobe signal.
The bidirectional shift register is shifted at STB’s rising edge.
FRMB (input)
Refers to the input pin of the frame signal.
The shift register data is read at STB’s rising edge.
DIR (input)
Refers to the input pin of the drive output’s shift direction selection signal.
When the shift direction selection signal (DIR) is “L”, the shift data (selection signal) is shifted from the drive
output X
1
to the X
240
direction. When “H”, it is shifted from the X
240
to the X
1
direction.
DOFFB’ (input)
Refers to the input pin of the display OFF signal.
It is placed in the display OFF status (all outputs at V1) at the “L” level. In the mean time, it reads the frame signal
and returns to the normal display status at the “H” level.
L1 & L2 (input)
Refer to the input pins of the drive level power selection signal.
In the case of the liquid-crystal drive output, the two lines are selected simultaneously by the shift register. L1
selects the first line, and L2 the second line. Both lines select V
DD
at “H”, and V
EE
at “L”.
