Sony ACX709AKN 7.60cm reflective color lcd module Datasheet

ACX709AKN
7.60cm Reflective Color LCD Module
Description
The ACX709AKN is a 7.60cm diagonal, 320 × 320
dots (102,400 effective pixels) active matrix reflective
color TFT-LCD module with a high performance front
light unit with touch panel. This panel provides ultrahigh reflection ratio with high contrast ratio. These
characteristics are realized by a newly developed
reflective electrode structure.

11. Requests on Handling (Be sure to read Separate Sheets 4 and 5 before handling.)
11-1. Do not input with anything but your finger or the dedicated pen. Also, do not stack or place heavy
objects on the product.
11-2. Avoid mechanical shocks, vibration and drops.
11-3. Do not expose the product to water, organic solvents or chemical products such as acids or alkalis.
Also, do not store the product in these atmospheres.
11-4. Hold the edges of the glass when moving the product. Gripping the product inside the effective
operation area may cause scratches or dirtiness. Also, avoid handling only the cable or applying
excessive force to peripheral circuits, as this may damage the cable and result in disconnection.
11-5. If the film surface becomes dirty, wipe it clean using a commercially available eyeglass cleaner or
other soft, dry cloth.
12. Notes on Mounting
12-1. Do not pull on, apply excessive force to or fold the cable, as this may damage the cable and result in
disconnection.
12-2. Be careful not to apply an excessive load when mounting the product. Fixing the product with doublesided adhesive tape on the rear surface of the glass is recommended.

[Separate Sheet 1: Linearity Measurement Method]
Definition of Linearity
Apply a DC 5V load between the X direction and Y direction electrodes of the transparent tablet as shown in
Fig. 1, and label the voltage between the pressed location and reference surface as the output voltage (Eox,
Eoy). Then, measure the output voltage when each intersection of the 10mm lattice enclosed by A and B which
are located only a certain distance inside the visible area is pressed as shown in Fig. 2.

Plot the output voltage for each measurement position as shown in Fig. 3, and label the difference between the
voltage value on the lattice enclosed by A and B and the output voltage at the same position as (∆Ex, ∆Ey).
Linearity is defined as the ratio between (∆Ex, ∆Ey) and the potential difference between A and B (EABx,
EABy).
Transparent tablet linearity (X) = (∆Ex/EABx) × 100%

• Measuring equipment:
HIOKI 8802 MEMORY Hi CORDER
• Measurement conditions: Measurement voltage: 5V
Test resistor:
100kΩ
Switching operation: Holding a R8 silicon rubber rod, perform on and off
operation behavior with the same load and speed as
normal finger input.
Rise, fall time setting:
Rise: When the switch changes from off to on, the voltage at both ends
of the transparent tablet in the measurement circuit shown below
follows a curve such as that shown in the chart below. The rise
time is the time from 10% to 90% of the stable measurement
voltage.
Fall: When the switch changes from on to off, the voltage at both ends
of the transparent tablet in the measurement circuit shown below
follows a curve such as that shown in the chart below. The fall
time is the time from 90% to 10% of the stable measurement
voltage.

[Separate Sheet 4: Notes on Handling]
This touch panel is designed for use in standard applications (OA and other office equipment, industrial and
communications-related equipment, consumer use equipment, etc.). Avoid use in applications where malfunction
or misoperation may pose the risk of direct harm to people, or for special applications (aerospace, nuclear
power control, medical life support, etc.) which require extremely high reliability.
Touch panel
a) Do not rub or press on the touch panel with sharp blades or other pointed objects.
b) Do not excessively fold or bend the touch panel.
c) When storing the touch panel, use a packing box and store within the recommended storage temperature
range. Also make sure that an excessive load is not applied to the touch panel in the stored condition.
d) Avoid storing or using the touch panel under conditions exposed to water and organic solvents, or in an
acidic atmosphere.
e) Avoid using the touch panel in locations exposed to direct sunlight.
f) Do not peel apart or disassemble the touch panel.
g) Do not hold the touch panel by just the tail portion; hold the panel glass itself.
h) If the touch panel becomes dirty, wipe it clean using a cloth moistened with a neutral detergent or alcohol.
Should any chemicals adhere to the touch panel, wipe them off immediately in a manner that does not pose
an effect to the human body.
i) The glass edges are not beveled, so be careful not to cut yourself when handling the touch panel.
Structure
a) The environmental, mechanical and electrical characteristics and other specifications are guaranteed only
for the input area.
b) Condensation forming inside the touch panel does not indicate a malfunction. Condensation will disappear
naturally as the touch panel approaches room temperature, but avoid use in the condition where
condensation has formed as this may result in malfunction.
Electrical specifications and software
a) Contact resistance occurs in the conduction between the upper and lower electrodes, and this contact
resistance changes according to the finger or pen pressure. Design the software so that data is loaded after
the contact resistance stabilizes.
b) There are always individual differences in the resistance between pins of analog resistor film type touch
panels, and this resistance may also change over time or due to the environment. When designing the
software, be sure to provide calibration functions to align the display position with the input position.
c) Analog resistor film type touch panels have a structure such that when two points are pressed at the same
time, a dot is judged to have been input at the center of the line connecting those two points. Therefore, do
not compile software that requires two-point input.
d) When drawing with pen input, the line may be broken when the pen passes over a dot spacer. Therefore,
corrective functions should be included in the software.

[Separate Sheet 5: Notes on Mounting]
(2) Gap between the bezel and the touch panel
Provide a gap of approximately 0.5mm between the inside of the
bezel and top surface of the upper electrode of the touch panel. A
narrow gap between the bezel and the upper electrode of the touch
panel may result in unanticipated input.
(3) Use of buffer materials
When installing buffer materials between the inside of the bezel
and the upper electrode of the touch panel, provide a certain
amount of leeway to absorb differences in expansion and
contraction between the bezel and the upper electrode due to
temperature changes. If the buffer materials are firmly clamped,
they may be unable to fully absorb the expansion and contraction,
which may cause warping or deflection of the upper electrode of
the touch panel, possibly affecting both the appearance and
performance of the touch panel.
In addition, be sure to insert the buffer materials to the inside of the
insulated area.

5) Tail bending
Do not use a structure where the tail is strongly clamped, bent
sharply at the base, or otherwise subject to stress due to case
pressure or other factors. Otherwise, insulation defects or
disconnected circuits may result.

Insulated area
(4) Tolerance
The touch panel and the tail dimensions have tolerances of ± 0.2 to
0.3mm, so be sure to provide leeway of this amount between the
case and the connector.
(6) Mounting the touch panel
Be sure to use a structure that supports the touch panel from the
bottom such as by adhering the touch panel to the display. If the
structure adheres the inside of the bezel to the upper electrode of
the touch panel, the joint between the upper and lower electrodes
will be subject to stress and easily damaged.
0.5mm
(1) Bezel tip
Make sure the bezel tip falls between the input area and the
transparent area. If the bezel tip extends into the input area, when
the bezel is pressed the tip may press on the touch panel and
result in input.

(7) Input prohibited area
The area 2mm to the inside from the insulated area has a
structurally weak durability. Particularly if this area is pressed
during pen input, the film may stretch and be damaged, so make
sure the bezel opening does not extend into this area.
Bezel
Input prohibited area
(8) Ventilation holes
Some touch panels have ventilation holes to equalize the internal
and external air pressure. Be sure not to block these ventilation
holes when mounting the touch panel. In addition, moisture
accumulating near ventilation holes may seep into the touch panel,
so take care to prevent moisture from accumulating. Also avoid
situations where pressure from inside the equipment causes the
upper film of the touch panel to bulge.
