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 a schematic using the LCD_B module with an MSP430F6638, see the Ultra Low Power Blood Pressure And Heart Rate Monitor Reference Design.
