You have not specified how is LCD built.
Calculator LCD are often custom LCD with or without build-in controller.
Often, the controller is HT1621, which is a chip similar to RAM accessable though a serial interface which permit to enable/disable each LCD segment (1 bit for each segment).

If you have only the glass, without built-in controller, you need a MCU which internal LCD controller, or you need to place an external controller like HT1621 or similar.

Please tell me the reationship between the segments and the 6bit address.I mean how to assign bits to these segments.
