Sets the output mode of the reference voltage generator amplifier for setting the white level of
the positive-polarity and negative-polarity sides (when VPL and VNL are normally white), as
shown below.
Determine the amplifier capacity after sufficient evaluation with the actual TFT panel to be used.
0: Normal mode
1: High-power mode (output stage capacity: twice that of normal mode)
Sets the output bias current of the reference voltage generator amplifier for setting the white level
of the positive-polarity and negative-polarity sides (when VPL and VNL are normally white), as
shown below.
Sets the output mode of the reference voltage generator amplifier for setting the black level of
the positive-polarity and negative-polarity sides (when VPH and VNH are normally white), as
shown below.
Determine the amplifier capacity after sufficient evaluation with the actual TFT panel to be used.
0: Normal mode
1: High-power mode (output stage capacity: twice that of normal mode)
Sets the output bias current of the reference voltage generator amplifier for setting the black level
of the positive-polarity and negative-polarity sides (when VPH and VNH are normally white), as
shown below.
Determine the amplifier capacity after sufficient evaluation with the actual TFT panel to be used.
Sets the voltage value of the black level of positive polarity.
