Preliminary
40-common x 128RGB-Segment, in 4096-Color
4096-Color STN LCD DRIVER
s GENERAL DESCRIPTION
The NJU6820 is a STN LCD driver with 40-
common x 128RGB-segment in 4096-color. It
consists of 384(128xRGB)-segment segment, 40-
common drivers, serial and parallel MPU interface
circuits, internal power supply circuits, gradation
palettes and 61,440-bit for graphic display data
RAM.
Each segment driver outputs 16-gradation level
out of 32-gradation level of gradation palette.
Since the NJU6820 provides a low operating
voltage of 1.7V and low operating current, it is
ideally suited for battery-powered handheld
applications.
