There are two types of inputs, COM signal serial input (EXTMODE=”L”) and external COM signal input (EXTMODE=”H”).
EXTMODE=“L”
M1
:
LC polarity inversion flag: If M1 is "H" then VCOM="H" is output. If M1 is "L" then VCOM="L" is output.
※
1
:
LC inversion has been changed by M1 flag statement.
※
2
:
The periods of plus polarity and minus polarity should be same length as much as possible.
