AS1120

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.Key
