FUNCTION
Used as power supply pin for digital circuit, connected to +2.5 to +3.6 V.
Used as power supply pin for analog circuit, connected to +8.0 to +13.0 V.
Used as ground pin, connected to 0 V.
Used as input pins of start pulse and also used as output pins for cascade connection.
When "H" is input into start pulse input pin, data sampling is started. On completion of
sampling, "H" pulse is output to output pin for cascade connection. Pin functions are
selected by LBR. For selecting , refer to "Functional Operations".
Used as input pin for selecting the shift register direction. For selecting, refer to
"Functional Operations".
Used as input pin for parallel transfer from sampling memory to hold memory. Data is
transferred at the rising edge and output from LCD drive output pin.
Used as shift clock input pin. Data is latched into sampling memory from data input pin at
the rising edge.
Used as reference voltage input pins. Hold the reference voltage fixed during the period of
LCD drive output. For relation between input data and output voltage values, refer to
"Output Voltage Value". For internal gamma correction, refer to "Gamma Correction
Value". Observe the following relation for input voltage.
VLS > VH0 ≥ VH32 ≥ π ≥ VH256 ≥ VL256 ≥ π ≥ VL32 ≥ VL0 > GND.
Used as data input pins of R, G, and B colors. 8-bit x 2-pixel data are input from data pins
at the rising edge of CK. For relation between input data and output voltage values, refer
to "Functional Operations" and "Output Voltage Value". Select the data to be entered
into X, Y, and Z according to picture element arrays of the panel.
Used as LCD drive output pins which output the voltage corresponding to the input of data
input pins (XA0 to XA7, YA0 to YA7, ZA0 to ZA7, XB0 to XB7, YB0 to YB7, ZB0 to ZB7).
Data of XO1 to XO128 correspond to XA0 to XA7 and XB0 to XB7. Data of YO1 to YO128
correspond to YA0 to YA7 and YB0 to YB7, and data of ZO1 to ZO128 correspond to ZA0 to
ZA7 and ZB0 to ZB7. For relation between input data and output voltage values, refer to
"Functional Operations" and "Output Voltage Value".
Used as input pins for input data polarity exchange, POLA corresponds to XA0 to XA7, YA0
to YA7 and ZA0 to ZA7, and POLB corresponds to XB0 to XB7, YB0 to YB7 and ZB0 to ZB7.
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.
Used as polarity exchange pin of LCD drive output. Date is taken at the term when LS is
"H" and the output polarity of the LCD drive output pin is determined. For exchanging, refer
to "Output Characteristics".
