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 V
DD2
potential using an external resistor (R
EXT
). When not using
this function, however, short-circuit this pin to V
DD2
.

Refer to the table below for the percentage of current regulation when using the bias current control function.

Remark
Be aware that the above current consumption regulation percentages are not product-
characteristic guaranteed as they are based on the results of simulation.
Caution
Because the low-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.
