Transmissive Wide-Screen 2.7-Type
Low-Temperature Polycrystalline Silicon TFT
LCD Panels for Video Cameras
ACX370AKA
ACX384AKA
Sony has now developed two new 2.7-type wide-screen LCD panels, the ACX370AKA and ACX384AKA.
These panels feature an optical transmittance improved by 10% over current video camera LCD panels.
Both feature a dot count of 123k dots.
End product designers can select from two models which position the FPC connector at the right side or
at the lower side of the panel to match design requirements.

* The 2.7-type wide LCD panel optimal
for video cameras
* Optical transmittance increased by
10% over current models (the
industry’s highest level)
* Two FPC attachment options: right
side and lower side
* Further increases Sony’s lineup of
video camera LCD panels
2.7-Type Wide LCD
The ACX370AKA and ACX384AKA are 2.7-
type 16:9 aspect ratio 123k-dot LCD panels.
These were developed as follow-on products to
the current ACX347AK and feature a significantly
improved optical transmittance. These
devices flexibly support end products with two
FPC connector positions: the right side
(ACX370AKA) and the lower side
(ACX384AKA).
Improved Optical Transmittance
Recently, there have been increasing demands
for higher brightness in LCD monitors to
improve monitor visibility in outdoor use.
The ACX370AKA and ACX384AKA adopt
the latest low-temperature polycrystalline silicon TFT process technology. In this technology,
the area of the LCD pixel internal capacitors
(supplementary capacitors) has been
reduced to improve the aperture ratio. This
results in an optical transmittance increased
to 11% from the current 10% optical transmittance
of the ACX347AK, achieving the
industry's highest level.
Support for Two FPC Positions
The media used in video camera recording is
changing from tape to DVD, hard disk, and IC
memory. This means that there are a variety of
requirements on the LCD monitor to match
the diverse forms of contemporary end products.
Although up to now, the FPC connector
has always been located at the lower side, the
ACX370AKA features a new right side location
for this connector. This allows the monitor
structure (glass external dimensions) to be
made 1.8 mm smaller in the vertical direction.
(See figure 1.)
Expanded Video Camera LCD
Lineup
Since many video cameras transmit the signals
to the monitor through a hinge, most cameras
drive the monitor with an analog interface.
Customers who use the CXA3017 external
driver IC can configure any of the LCD panels in Sony’s extensive lineup (include the
ACX370AKA and ACX384AKA of this
release) with the same system structure. (See
figure 2.)
16:9/4:3 Display Switching
Function
The ACX370AKA and ACX384AKA include
the 4:3 display function (black sides) that was
appreciated by our customers in the
ACX347AK. By combining these panels with
the CXA3017 driver IC, the monitor can be
switched easily to 4:3 display with a monitor
operation when switching to the camera's still
image capture function. (See figure 3.)

The ACX370AKA and ACX384AKA are 2.7-type wide-screen LCD panels for video
cameras. They feature improved optical
transmittance and the addition of a right
side FPC position version for improved
ease of use. These devices are our first
new products with analog interface specifications
in two years. Our lineup in this
area dates back to 1999 and has now
become even more extensive. Thank you
for your use of Sony products over the
years.
