2.3 Write Operation Timing

Vcom signal is stable enough to operate. Make sure to evaluate this output operation sufficiently.
Output voltage
Therefore, performing Vcom inversion while INH = L causes current flow to these IC output pins, which may result
The output operation of this IC is controlled by INH signals.
The sampled video signals are written to the LCD panel by output currents I
