Note 1: Gate off voltage, V
EE
=-5.5V.
Note 2 : Gate on voltage, V
GG
=15.4V.
Note 3 : Select up or down shift ( see Table 1 )
Note 4 : Gate driver shift clock
Note 5 : When OE is connected to high “1”, the driver outposts
are disabled (Gate output=V
EE
). Under this condition,
the operation of registers will not be affected.
Note 6 : Select left or right shift (
see Table 2 )
Note 7 : Latch the polarity of outputs and switch the new data
to outputs. At the rising edge (LD), latch the “POL”
signal to control the polarity of the outputs.
Note 8 : Control whether the Data RO~G5 are inverted or not.
(PVI suggests connecting to GND) When “REV=1”
these data will be inverted. EX: “00”
to “3F”, “07” to
“38”, “15” to “2A”
Note 9 : Polarity selector for dot-inversion control. Available
at the rising edge of LD. When POL=1: Even outputs
range from V1~V7, and Odd outputs range from
V8~V14, and Odd outputs range from V1~V7.
Note 10: VDD2 = 7.7V (Typical Application Circuit (when V1=7.7V)
