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.
