OUTn DRIVER OPERATION
Does not turn on
Turns on for one GSCLK period in the first display segment
Turns on for one GSCLK period in the first and 65th display segments
Turns on for one GSCLK period in the first, 65th, and 33th display segments
Turns on for one GSCLK period in the first, 65th, 33th, and 97th display segments
Turns on for one GSCLK period in the first, 65th, 33th, 97th, and 17th display segments
Turns on for one GSCLK period in the first, 65th, 33th, 97th, 17th, and 81th display segments
The number of display segments where OUTn is turned on for one GSCLK is incremented by
increasing GS data in the following order:
1 > 65 > 33 > 97 > 17 > 81 > 49 > 113 > 9 > 73 > 41 > 105 > 25 > 89 > 57 > 121 > 5 > 69 > 37 >

Turns on for one GSCLK period in the first to 127th display segments, but does not turn on in the
128th display segment
Turns on for one GSCLK period in all display segments (first to 128th)
Turns on for two GSCLK periods in the first display period and for one GSCLK period in all other
display periods
The number of display segments where OUTn is turned on for one GSCLK is incremented by
increasing GS data in the following order:
1 > 65 > 33 > 97 > 17 > 81 > 49 > 113 > 9 > 73 > 41 > 105 > 25 > 89 > 57 > 121 > 5 > 69 > 37 >

Turns on for two GSCLK periods in the first to 127th display segments and turns on one GSCLK
period in the 128th display segment
Turns on for two GSCLK periods in all display segments (first to 128th)
Turns on for three GSCLK periods in the first display segments and for two GSCLK periods in all
other display segments
The number of display segments where OUTn is turned on for one GSCLK is incremented by
increasing GS data in the following order:
1 > 65 > 33 > 97 > 17 > 81 > 49 > 113 > 9 > 73 > 41 > 105 > 25 > 89 > 57 > 121 > 5 > 69 > 37 >
