In chip-on-glass technology, where driver devices are
bonded directly onto glass of the LCD, it is important that
the devices may be cascaded without the crossing of
conductors, but the paths of conductors can be continued
on the glass under the chip. All of this is facilitated by the
PCF8576 bonding pad layout (see Fig.30). Pads needing
bus interconnection between all PCF8576s of the cascade
are V
lines may be led to the corresponding pads of the next
PCF8576 through the wide opening between V
