Power.
Logic circuit power ground (OV).
The GND and DGND pins are interconnected
inside the chip with a resistor in between.
Be sure to keep
both pins at the same potential.
When the OE input level gets low, all the output signals to the TFT panel - DX, CLXi, CLXi (i =l thru 4),
DY, CLY, CLY, and ENOUT - come to low level too.
Be sure to fix the non-used inverter input and NAND input at the high or low level.
Switching
between the VIDEO and WIDE modes goes as follows depending
on the WMODE and
VMODE input levels.
L: Low level, H: High level.

VLS:
During the "H" period, the black-level video
signal is put into the TFT panel.
In the power-saving
mode with no display, the CLXl thru CLX4 signals are all at low level, whereas the
CLX1 thru CLX4 signals all at high level.
Keep all the test terminal inputs at low level.
'
Keep open the test terminal reference signal outputs - MOUTl
and MOUT2.
