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

A liquid crystal display driver has N common drive lines and M segment drive lines. A liquid crystal display has M segment driver leads and N times P common drive leads, P being at least two. P multiplexers are provided, each external to the liquid crystal display driver. Each of the M segment driver lines is connected with a respective one of the M segment drive leads. Each multiplexer comprising N switches, each switch defining a normally-open contact, a normally-closed contact, and a common contact. Each of the switches is connected by its common contact with a respective one of the common drive leads of the liquid crystal display. Each of the switches is connected by its normally-closed contact with a cancel signal. The N switches of each multiplexer are each connected with a respective one of the N common drive lines of the liquid crystal display driver.
