SYMBOL

FUNCTIONS

XO1-XO108

YO1-YO108

ZO1-ZO108

Used as LCD drive output pins which output the voltage corresponding to the input of data

input pins. When 321-output mode, 3 outputs (XO54 to ZO54) are invalid. When 312-output

mode, 12 outputs (XO55 to XO58, YO55 to YO58, ZO55 to ZO58) are invalid. When 309-

outputs mode, 15 outputs (XO54 to XO58, YO54 to YO58, ZO54 to ZO58) are invalid. Invalid

output pins must be opened. Data of XO1 to XO108 correspond to XA0 to XA5 and XB0 to

XB5. Data of YO1 to YO108 correspond to YA0 to YA5 and YB0 to YB5, and data of ZO0 to

ZO108 correspond to ZA0 to ZA5 and ZB0 to ZB5. For relation between input data and

output voltage values, refer to "Functional Operations" and "Output Voltage Value".

POLA

POLB

Used as input pins for input data polarity exchange, POLA corresponds to XA0 to XA5, YA0

to YA5 and ZA0 to ZA5, and POLB corresponds to XB0 to XB5, YB0 to YB5 and ZB0 to ZB5.

When "L" is entered, display data becomes normal mode. When "H" is entered, input data

becomes polarity exchange mode. For relation between input data and output voltage

values, refer to "Output Voltage Value". These pins are pulled down at the inside.

REV

REV2

Used as polarity exchange pins of LCD drive output. Data is taken at the term when LS is

"H" and the output polarity of the LCD drive output pin is determined. Function of REV is

the same as function of REV2. Input polarity exchange signal to REV, and REV2 is fixed to

"L" or opened in general.

When 321-output/309-output mode, it is possible to exchange output polarity between LCD

driver next to each other by fixing REV2 to "L" or "H" according to position on panel. For

exchanging, refer to "Output Characteristics". REV2 pin is pulled down at the inside.
