Multiplexing 8-digit segment LCD
An 8-digit LCD will (probably) not be a static drive type because it would require 60+ conductors.
Multiplexing (such as triplexing) reduces the number of conductors but the drive waveforms become multi-level and the contrast becomes more sensitive to temperature. You must have a display designed for the type of multiplexing you want to do.
There are chips designed for driving (say) triplexed multi-digit displays such as the MAX723x series. They tend to be expensive.
There are also inexpensive 8-bit micros with on-chip LCD drivers with various capabilities, which I would definitely recommend (you can do a search in your favorite families of products for the presence of such a peripheral and compare capabilities to your requirements).
There are other more Rube Goldberg methods of accomplishing this, but the above would be what I would suggest.
For example, this 8-digit display features 3 commons (triplexed), so it has only 30 pins for 8 digits. It has pins so it's aimed at relatively low volume/high price applications most likely. Note that the segment/common pairings are probably not what you'd choose- they are more dictated by the requirements of making the display conductors not cross over.
