Apparatus and method for use of large liquid crystal display with small driver

Apparatus comprising:

• a liquid crystal display driver having N common drive lines and M segment drive lines, the liquid crystal display driver comprising an integrated circuit;
• a liquid crystal display having M times R segment driver leads and N times P common drive leads, wherein P is at least two and R is at least two;
• P common drive lead multiplexers, each external to the integrated circuit;
• and
• R segment drive lead multiplexers, each external to the integrated circuit;
• each segment drive lead multiplexers comprising M switches, each switch defining a normally-open contact, a normally-closed contact, and a common contact;
• each of the switches of the segment drive lead multiplexer connected by its common contact with a respective one of the segment drive leads of the liquid crystal display;
• each of the switches of the segment drive lead multiplexer connected by its normally-closed contact with a cancel signal;
• the M switches of each segment driver lead multiplexer each connected with a respective one of the M segment drive leads of the liquid crystal display driver;
• each common drive lead multiplexer comprising N switches, each switch defining a normally-open contact, a normally-closed contact, and a common contact;
• each of the switches of the common lead multiplexer connected by its common contact with a respective one of the common drive leads of the liquid crystal display;
• each of the switches of the common lead multiplexer connected by its normally-closed contact with a cancel signal;
• the N switches of each common lead multiplexer each connected with a respective one of the N common drive lines of the liquid crystal display driver.
