KS0724 PRELIMINARY SPEC. VER. 0.8 65 COM / 132 SEG DRIVER & CONTROLLER FOR STN LCD
1
INTRODUCTION
The KS0724 is a single chip driver & controller LSI for graphic dot-matrix liquid crystal display systems. This chip
can be connected directly to a microprocessor, accepts serial or 8-bit parallel display data from the
microprocessor, stores the display data in an on-chip display data RAM of 65 x 132 bits and generates a liquid
crystal display drive signal independent of the microprocessor. It provides a high-flexible display section due to 1-
to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. It contains 65 common driver
circuits and 132 segment driver circuits, so that a single chip can drive a 65 x 132 dot display. And the capacity of
the display can be increased through the use of master/slave multi-chip structures.
These chip are able to minimize power consumption because it performs display data RAM read / write operation
with no external operation clock. In addition, because it contains power supply circuits necessary to drive liquid
crystal, which is a display clock oscillator circuit, high performance voltage converter circuit, high-accuracy voltage
regulator circuit, low power consumption voltage divider resistors and OP-Amp for liquid crystal driver power
voltage, it is possible to make the lowest power consumption display system with the fewest components for high
performance portable systems.
