Hi all,
We use a multiplexed (1:3) custom LCD Glass in a product that has 135 Segments, e.g. needs 45 Segment drivers when using 3 common lines.
Up to now, we used a Hitachi controller that is now discontinued. All other drivers I could find only support 40 segment driver outputs max.
If possible, we would like to avoid to make a new glass that is multiplexed 1:4. A serial interface to the host controller is acceptable, e.g. SPI or I2C bus.
Does anybody know an integrated circuit that features 45 segment outputs and supports triplexed LCD glasses?
Thanks for all hints, Heiner
