Portrait-type 8.9 cm (3.5-type) QVGA Reflective Color LCD Module
with Built-in Touch Panel and 4-bit D/A Converter
ACX706AKM
To provide color display for PDAs and other portable information
terminals, Sony has now developed the ACX706AKM 8.9 cm (3.5-type)
portrait-type QVGA color LCD module based on low-temperature poly-
crystalline silicon reflective LCD technology.
This new product adopts a full module form that consists of a portrait-
type LCD panel with a built-in 4-bit D/A converter, a newly-developed
thin high-efficiency LED front light, and a touch panel optimized for
use with reflective LCD panels. The result is a high-brightness, high
image quality, low-power (65 mW) LCD module.
Additionally, Sony has integrated the controller and driver
functions that have conventionally been implemented with two chips
in a single chip in the newly-developed CXD3513GG for simplification
of the total system.

LCD Full Module Form
Includes Touch Panel
The newly-developed ACX706AKM is
Sony’s first full module form, and as
such includes an LCD panel, a front
light, and a touch panel. By adopting
the full module form, Sony was able to
optimize the optical design of the touch
panel, the front light, and the high
reflection ratio panel that is based on
the RMP (random multi-profile) struc-
ture and an advanced BDM design
retardation film. This also allowed
optimal matching of the polarizers. As
a result, this product achieves, even with
the touch panel included, a high
contrast ratio (12:1 typical) and a high
reflection ratio (24% typical). An anti-

While this is our third reflective
display module, it is no way
inferior to either of the others.
I hope you will consider the
ACX706AKM 3.5-type LCD,
which is optimal for portable
information terminals. I’m sure
that, once you see it, you will be
able to image a wide range of
applications for this module.
reflective coating applied to the touch
panel allows this device to be used out-
doors.
Thin High-Efficiency
Newly-Developed LED
Front Light
The ACX706AKM adopts a newly-
developed ultrasmall white LED, and
features an optimized optical design that
allows it to achieve a brightness of 5
cd/m ² (typical) at a power consumption
of 105 mW (typical). Furthermore, in
addition to the LED front light featur-
ing a rapid turn-on time, it also features
superlative brightness stability at low
temperatures. Thus this device supports
use in a wide range of operating
environments.
Low-Power Panel and
Newly-Developed
Single Chip IC
The ACX706AKM panel takes advan-
tage of Sony’s unique circuit and
low-temperature polycrystalline silicon
TFT technologies developed in previ-
ous 2.7-type and 3.8-type panels, and
achieves high reliability, high quality,
and low power (the panel itself
consumes 20 mW). Furthermore, Sony
has integrated the controller and driver
functions that have conventionally been
implemented with two chips in a
single chip in the newly-developed
CXD3513GG. The integration of these
functions on a single chip increases the
degrees of freedom available to the
PWB layout designer, and achieves the
low power consumption of 65 mW
(with the front light off) when the panel
is actually driven.
Following the development of 2.7-type
and 3.8-type panels, Sony has now
added the newly-developed
ACX706AKM 3.5-type portrait-type
LCD panel to its product line of
reflective LCD products to respond to
a wide range of needs in the portable
information terminal area.
