< Bias Current Control Function (Bcont) >
It is possible to fine-control the current consumption by using the bias current control function (Bcont pin). When
using this function, connect this pin to the stabilized ground potential (VSS2) via an external resistor (REXT). When not
using this function, leave this pin open.

Remark The above current consumption regulation percentages are founded on
results of simulation and don’t assuring a characteristics of this product.
Caution Because the power and bias-current control functions control the bias current in the output amplifier
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.
