< Bias Current Control Function (Bcont) >
using this function, connect this pin to the stabilized ground potential (V
using this function, leave this pin open.
Caution Because the power and bias-current control functions control the bias current in the output amplifier

It is possible to fine-control the current consumption by using the bias current control function (Bcont pin). When
Refer to the table below for the percentage of current regulation when using the bias current control function.
and regulate the over-all current consumption of the driver IC, when this occurs, the characteristics
of the output amplifier will simultaneously change. Therefore, when using these functions, be sure
to sufficiently evaluate the picture quality.
