Enables high-precision
緯
correction using logarithmic
compression.
緯
correction for normally white LCD panel is possible.
Offset/cancel input circuit enables high-quality
緯
correction
without distorting the primary color input signals.
Cut-off voltage and drive voltage can be independently
controlled.
Unsusceptible to negative effects of fluctuation of power
supply voltage.
Either latch mode or through mode can be selected using the CH display mode switching pin.
