81 COM / 104 SEG DRIVER & CONTROLLER FOR STN LCD
INTRODUCTION
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. It 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 power
consumption. 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.
