Required LCD connections greatly vary by the type of display that is used (static or multiplexed), whether external or internal biasing is used, and also whether the on-chip charge pump is employed. For any display used, there is flexibility as to how the segment (Sx) and common (COMx) signals are connected to the MCU, which (assuming that the correct choices are made) can be advantageous for the PCB layout and for the design of the application software.
Because LCD connections are application specific, it is difficult to provide a single one-fits-all schematic. However, for an example of connecting a 4-mux LCD with 40 segment lines that has a total of 4 × 40 = 160 individually addressable LCD segments to an MSP430FR6989, see the Water Meter Reference Design for Two LC Sensors, Using Extended Scan Interface (ESI).
