General Description
The AS1120 is an LCD direct-driver capable of driving up to 46 LCD segments with one non-multiplexed backplane.
The device contains an integrated serial-to-parallel interface and generates the necessary signals to drive LCD panels.
Internal synchronous backplane signal regeneration allows the device to mix different drivers with different LCDs for superior brightness stability over a wide temperature range. The device also supports external backplane signals.
