Beautiful Full Wide Display |
|
Due to the start of One-Seg digital TV
broadcasts in Japan, wide-screen display
is now desired in cellular phones as well
as TV sets and monitors. Furthermore, due
to improvements in cellular phone camera
performance and the richer content
available from Internet services, there are
increasing needs for higher resolution image
display. The ACX359AKM features
a display resolution of 240 × RGB × 432,
and can display 16:9 full wide images
without changing the size. Since the pixel
count has been increased by 35% over the
earlier QVGA format, images and text can be seen more clearly. Furthermore, the
ACX359AKM achieves both a viewing
angle of over 160 degrees in the up/down
and/or left/right directions and a high contrast
in excess of 500:1 and provides truly
beautiful image display. |

Thin-Form Module |
|
To contribute to thinner form factors in
cellular phones, the LCD glass and the
white LED backlight light guide plate are
being made even thinner, and Sony has
now reduced the overall thickness of the
module to a mere 1.75 mm, including the
backlight system. (This corresponds to a
12% reduction from earlier similar products.)
Sony adopted a glass polishing
method to reduce the thickness of the LCD
glass and achieved a total thickness of 0.4
mm, a 50% reduction from earlier products.
To reduce the thickness of the backlight
light guide plate, Sony adopted a
unique light guide geometry to reduce light
leakage outside the light guide plate, and
achieved the same brightness level as the
earlier 0.45 mm thickness light guide plate
with a 0.35 mm thick light guide plate, thus
achieving a module surface brightness of
350 cd/m2. |

Narrow Frame System Display |
|
To contribute to further miniaturization of
cellular phones, Sony has evolved their
system display technology (technology for
integrating drive circuits on the glass)
inherited from earlier products even further
and succeeded in reducing the FPC
mounting side frame to 5.5 mm, a 20%
reduction from earlier products. This
allows the overall size of the cellular
phone to be held to a minimum despite
the larger display size. |

In this new product, we
responded to the challenges
presented by every aspect of the
design, from the optical characteristics
and module thickness to
the drive technique. Although it
was a difficult birth, we created a
product that we can present to our
customers with confidence.
I strongly recommend that you
consider this device. |
