The KS0718 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 81 common and 104 segment driver circuits. This chip is connected directly to a microprocessor, accepts serial or 8- bit parallel display data and stores in an on-chip display data RAM of 89 x 104 bits. KS0718 provides a highly flexible display section due to 1-to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. And it performs display data RAM read/write operation with no externally operating clock to minimize powerconsumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
