High Reflectivity
and High Transmittance |
|
While the reflectivity
of most low-reflectivity LCDs is on the order
of 1 to 2%, the ACX527AKM achieves both a high
reflectivity (16.5%) and a high transmit-tance
(4.6%*1 )
at the same time by adopting a unique pixel
structure. (See figure 1.)

is not used. |

Wide Viewing
Angle |
|
That they can be seen
from a wide range of viewing angles is a major
feature of Sony transflective LCD monitors.
(See figure 2.) The monitors are easy to see,
from whatever angle they are observed. Also,
since wide viewing angle LCDs are effective
as store display products, they can increase
the sales potential of digital still camera
products. |
|
Low Power
Consumption |
|
Sony succeeded in
significantly reducing power consumption by
changing from the conventional COMDC drive to
the COMAC drive scheme. Furthermore, since the
ACX527AKM has an extremely high reflectivity,
the screen can be read even in the state where
the backlight is completely off. This point
contributes greatly to reduced power consumption.
(See figure 3.) |
|
Digital Interface |
|
The merits of using
a digital interface include the point that no
A/D converters are required, low noise, and
adjustment-free manufacturing of end products.
The ACX527AKM, of course, also supports use
of a conventional analog interface. |
|
High Color
Purity and High Picture Quality |
|
In the area of color
reproducibility as well, the ACX527AKM continues
to use the highly regarded six color filters,
and color evenness within the frame has also
been improved by adopting pillar spacers. The
color purity in reflective mode is high, and
since the reflector is finely patterned (see
figure 4), the reflected image is natural and
no unnatural images occur on the boundary between
reflective and transmissive operation. |
|
Thin Form
Factor |
|
The ACX527AKM is extremely
thin, with a module thickness of only 3.07 mm*2
including the backlight, and can contribute
to miniaturization and thinner form factors
in end products.

|
Can Use Existing
Drivers |
|
The CXM4006 (digital
interface) and the CXM3005 (analog interface)
drivers that are common to the other Sony low-power
type LCDs can be used to drive the ACX527AKM. |
|
Contributes
to Eliminating OVF |
|
Since it never becomes
impossible to view the LCD image due to external
light, an expensive OVF (optical viewfinder)
is not required. Thus the ACX527AKM contributes
to end product design both in the materials
and the space aspects. |
|
Up/Down and/or
Right/Left Inversion Functions |
|
These functions increase
the flexibility of LCD layout within the end
product, and can also be used to simply provide
a screen reversal function for rotating monitor
end products. |
|
Ratio Viewing
Area: 100% |
|
Since the ACX527AKM
supports a ratio viewing area of 100%, it is
possible to verify that none of the desired
image was excluded from the image being taken,
or in images already taken. |
