ACX703AKM Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Low Power Consumption and High Picture Quality 2.0-inch 200K-dot Reflective Color LCD

Low Power Consumption and High Picture Quality
2.0-inch 200K-dot Reflective Color LCD
ACX703AKM
By combining the ACX301AK, which concentrates Sony’s low-
temperature polysilicon TFT LCD technology, with Sony’s unique
and superlative reflective technology, Sony has succeeded in de-
veloping a revolutionary small reflective panel, the ACX703AKM,
that achieves low power, high resolution, high contrast, high re-
flection ratio, and the ability to display pure white.
This device is optimal for use in digital still cameras, which require
low power and high picture quality.
Sony has developed, at the same time, two drive IC options to
powerfully support this reflective LCD panel. One is the single-chip
IC CXA3268R, and the other is a two-chip system timing generator
IC CXD2472R. Thus the ACX703AKM can respond to a wide range
of product planning needs.

s Natural color and pure white dis-
play provided by BDM technology

Low-power Circuits Used
The ACX703AKM uses the same
circuits as the ACX301AK 2.0-inch
200K-dot color LCD. These internal
circuits are all formed from low-tem-
perature polysilicon TFTs, and thus this
product achieves a power consumption
of 50 mW when 12-V drive is used.
Thus this product, through the use of
low-power circuits, is a panel system
that strives for even more ultralow-
power consumption, which is a feature
of reflective LCD panels that do not re-
quire a backlight.
VOICE
Sony has developed the reflective
LCD of the ACX301AK . While the
ACX703AKM, which takes full ad-
vantage of Sony’s unique high-
performance reflective LCD
technology, is a high-resolution
reflective LCD, this product is
designed to achieve low power
consumption. This device, along
with Sony’s drive ICs that support
all types of application, form a
powerful combination that is
strongly differentiated from the
competition. I strongly recom-
mend that you look into this
product.
Sony’s Unique Reflective
LCD Panel Technology
In addition to low-power technology,
Sony has taken full advantage of the
unique high picture quality technolo-
gies, including ECB*¹ mode, the
RMP*² structure, and the BDM*³ tech-
nology, all of which achieve improved
brightness and higher contrast. This has
resulted in the achievement of a reflec-
tion ratio of 28% and a contrast ratio of
19:1.

Related Products that
Powerfully Support the
ACX703AKM and the ACX300
Series
Sony provides two types of system as
the ACX703AKM drive ICs to support
customer needs.
One is a two-chip structure based on
existing driver ICs using the
CXD2472R as the timing generator.
(See figure 1.) The other is a single-chip
structure based on the CXA3268R, and
allows reduced space and a smaller
number of components. (See figure 2.)
These options allow customers to select
a structure that fits their product designs.
Both these drive ICs can also drive the
ACX300AK, ACX301AK, and
ACX302AK*⁴, which are transmissive
panels. Sony is also releasing, at the
same time, a backlight specially
designed for use with the ACX301AK,
which is a 2.0-inch 200K-dot transmis-
sive panel. The ACX301AK backlight
adopts a unified structure with the panel
itself, and thus can achieve the light
weight, small-sized, and low power that
are optimal for digital still camera ap-
plications.
