STN LCD DRIVER
!
GENERAL DESCRIPTION
The
NJU6823
is a STN LCD driver with 128-common x
(128+2) RGB-segment in 4096-color. It consists of
384(128xRGB)-segment + 6(2xRGB)-icon segment, 128-
common drivers, serial and parallel MPU interface circuits,
internal power supply circuits, gradation palettes and
196,608-bit for graphic display data RAM.
Each segment driver outputs 16-gradation level out of
32-gradation level of gradation palette.
Since the
NJU6823
provides low operating voltage of
1.7V and low operating current, it is ideally suited for
battery-powered handheld applications.
