Description
2.7 to 3.6 V
7.0 to 12.0 V
Ground (0 V)
Ground (0 V)
The D/A converted 64 gray-scale analog voltage is output.
RSDS data input
Total data lines consist of 18 data bus.
(6-bit digital, 3 colors(R, G, B) and 2 differential input pairs)
The 3-bit differential input pairs generate the internal 6-bit data through
the comparison between DxxP and DxxN.
Shift direction control
input
This pin controls the direction of shift register in cascade connection.
When SHL=H: DIO1 input, Y1→Y384, DIO2 output
When SHL=L: DIO2 input, Y384→Y1, DIO1 output
Start pulse input/output
SHL=H: Used as the start pulse input pin.
SHL=L: Used as the start pulse output pin.
Start pulse input/output
SHL=H: Used as the start pulse output pin.
SHL=L: Used as the start pulse input pin.
Data inversion input
DATPOL= L: No inversion
DATPOL= H: Data polarity inversion
( DATPOL must be fixed VSS1 or VDD1.)
Polarity input
POL=H: The reference voltage for odd number outputs are VGMA1 to
VGMA7 and those for even number outputs are VGMA8 to VGMA14.
POL=L: The reference voltage for odd number outputs are VGMA8 to
VGMA14 and those for even number outputs are VGMA1 to VGMA7.
RSDS shift clock input
The RSDS clock input pairs generate the internal shift clock, CLK2,
through the comparison between CLKP and CLKN.
Latch input
S6C1108 clears 128 shift registers at the rising edge of CLK1 and
outputs the analog data to the each channel at the falling edge.
Gamma corrected power
supplies
Input the gamma corrected power supplies from external source.

Keep power supplies unchanged during the gray-scale voltage output.
Amp test input/output
These pins are used for Amp test.
