VGA Display |
|
The high-performance pixel transistor
achieved by the low-temperature polycrystalline
silicon technology of which Sony
is proud makes VGA display (223 ppi)
possible despite the 8.8 cm (3.6-type) size
of the display. The finest parts of the image
can be displayed and smooth curved
lines can be displayed in photographs and
other images. This is a truly high-performance
display that can handle any type of
content. |
|
Built-in VGA/QVGA Switching
Function |
|
The integration of a VGA/QVGA switching
circuit on panel glass was made possible
by the fusion of Sony's circuit design
technologies and the high-performance
pixel transistor achieved by the
low-temperature polycrystalline silicon
technology of which Sony is proud. This
allows the selection of a mode optimal for
the content being displayed. (See figure 1
and photograph 1.) Furthermore, the combination
and integration of the operation
circuits starting with the scanner circuit,
makes all display operations possible with
just a single COG chip. These technologies
not only achieve high display performance,
but they also assure high reliability. |

Ultrathin Module Structure |
|
This panel includes a newly-developed
thin film type touch panel. Even with a
backlight included, Sony was able to create
an ultrathin module with a thickness
of 3.4 mm (typical). (See figure 2.) This
technology contributes greatly to improved
ability to withstand mechanical
shock and lower weight as compared to
conventional glass touch panels, and
makes the ACX526AKM an optimal display
module for high-performance PDAs
that place an emphasis on portability. |
|
High Display Performance |
|
To achieve this ultrahigh resolution, Sony
optimized the LCD cell optical design and
the pixel device structure. Even though
this panel adopts a high-resolution pixel
pitch that makes assuring an adequate aperture
ratio extremely difficult, this device
assures a 6% (typical) reflectivity. Sony
also achieved at the same time the high
brightness of 80 nit (typical), thus achieving
overwhelming display performance,
whether indoors or outdoors.
This is an LCD display that allows mobile
tools to exhibit their full potential and
charisma to the utmost, regardless of the
user's environment. |

In all aspects of the specifications,
high resolution, high brightness,
wide color reproducibility, and
light weight, this is a product that
we can be extremely proud of. Although
it was particularly difficult
to achieve both higher resolution
and good optical characteristics at
the same time, all the members of
the development team worked together
as one to create a truly superb
LCD product. |
