GENERAL DESCRIPTION
The
NJU6824
is a STN LCD driver with 128-common x
(128+2) RGB 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.
The display rotate function makes easily rotated display
without original display data change.
Since the
NJU6824
provides a low operating voltage of
1.7V and low operating current, it is ideally suited for
battery-powered handheld applications.
