N-RASTER-ROW REVERSED AC DRIVE
The S6D0114 supports not only the LCD reversed AC drive in a one-frame unit but also the n-raster-row reversed
AC drive which alternates in an n-raster-row unit from one to 64 raster-rows. When a problem affecting display
quality occurs, the n-raster-row reversed AC drive can improve the quality.
Determine the number of the raster-rows n (NW bit set value +1) for alternating after confirmation of the display
quality with the actual LCD panel. However, if the number of AC raster-row is reduced, the LCD alternating
frequency becomes high. Because of this, the charge or discharge current is increased in the LCD cells.
