In the past, liquid crystal display systems have been driven by the logic generated by hard wired components. These include gates, shift registers, and both randomly accessed and read-only memories. However, as liquid crystal displays become larger and the logic becomes more complex, the possibility of interlaced scanning of a matrix display must be allowed for as well as the task of slowing data entry during the introduction of new data while maintaining a high rate of scan and refreshing old data. Also, various pulse modulation modes may be used. The pattern of connecting wires to the display may not, however, be the most convenient for implementing these additional features with the requirement that interconnecting leads in the hard wired logic be switched or changed around and the need for additional gates, registers and wiring.
