DETAILS OF PIN FUNCTIONS
STB (input)
Input pin of the row drive strobe signal
The bidirectional shift register is shifted at STB’s rising edge.
/FRM (input)
Input pin of the frame signal
The shift register data is read at STB’s rising edge.
DIR (input)
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
160
direction. When “H”, it is shifted from the X
160
to the X
1
direction.
/DOFF
’
(input)
Input pin of the display OFF signal
It is placed in the display OFF status (all outputs at V
1
) 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 and L2 (input)
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 selects the second line. Both lines select V
DD
at “H”, and V
EE
at “L”.
