NJU6824
Preliminary
128-common x (128+2) RGB-Segment, in 4096-Color
STN LCD DRIVER
s GENERAL DESCRIPTION
The NJU6824 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.
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.
