2.3 Write Operation Timing
The sampled video signals are written to the LCD panel by output currents I
VOL
and I
VOH
via output buffer. The
dynamic range is 4.3 V
MIN
. (V
DD2
= 5.0 V).
While INH = H, do not stop shift clocks CLI
1
through CLI
3
.
The output operation of this IC is controlled by INH signals.
INH = Hiz
INH = Connected with internal circuit
(switch sample and hold circuit at the falling edge.)
Therefore, performing Vcom inversion while INH = L causes current flow to these IC output pins, which may result
in malfunction. Perform Vcom in version during INH = H (Hi-z) and start output operation of the next line after the
Vcom signal is stable enough to operate. Make sure to evaluate this output operation sufficiently.
