Capacitors for V1OUT and V4OUT
may be inserted after confirming the
display quality.
And additional capacitors for other
VnOUTs may be inserted after
confirming the display quality.
Notes: 1. These relationships between LCD driving current (I
) and the external capacitors are applied to
designing LCM, but they cannot guarantee the practical display quality. This display quality
depends on LCD panel size and LCD material used, and it must be checked and confirmed with
your LCD panel.
2. These LCD driving currents (I
) depend on the LCD driving voltage between V
CC
and V
EE
, and
setting of VREF, VREFP and VREFP pins.
3. Especially the capacitors for V1OUT and V4OUT are most efficient for display quality.
4. This condition is an example when the frame frequency is 60Hz to 100Hz. If higher frame
frequency is used, these external capacitors should be enhanced to prevent the cross-talk.
