Warning
1. This Kyocera LCD module has been specifically designed for use only in
electronic devices and industrial machines in the area of audio control,
office automation, industrial control home appliances, etc. The module
should not be used in applications where the highest level of safety and
reliability are required and module failure or malfunction of such module
results in physical harm or loss of life, as well as enormous damage or loss.
Such fields of applications include, without limitation, medical, aerospace,
communications infrastructure, atomic energy control. Kyocera expressly
disclaims any and all liability resulting in any way to the use of the module
in such applications.
2. Customer agrees to indemnity, defend and hold Kyocera harmless
from and against any and all actions, claims, damages, liabilities,
awards, costs, and expenses, including legal expenses, resulting from or
arising out of Customer's use, or sale for use, or Kyocera modules in
applications.
Caution
1. Kyocera shall have the right, which Customer hereby acknowledges, to
immediately scrap or destroy tooling for Kyocera modules for which no
Purchase Orders have been received from the Customer in a two-year period.

10. Design guidance for analog touch panel (T/P)
10-1 Electrical (In customer's design, please remember the following considerations.)
1 Do not use the current regulated circuit.
2 Keep the current limit with top and bottom layer. (Please refer to “Electrical absolute maxim
um ratings” for details.)
3 Analog T/P can not sense two points touching separately.
4 A contact resistance is appeared at the touch point between top and bottom layer.
After this resistance has stable read of the T/P position data.
5 Because noise of inverter or peripheral circuits may interfere signal of touch panel itself
 it is necessary to design carefully in advance to avoid these noise problem.
10-2 Software
1 Do the "User Calibration".
2 "User Caribration" may be needed with long term using.
Include "User Caribration" menu in your software.
3 When drawing a line with a stylus, there may be a slight discontinuity when the stylus
passes over a spacer-dot. If necessary, please provide a compensation feature within your software.
10-3 Mounting on display and housing bezel
1 Do not use an adhesive tape to bond it on the front of T/P and hang it to the housing bezel.
2 Never expand the T/P top layer (PET-film) like a balloon by internal air pressure.
The life of the T/P will be extremely short.
3 If a dew will be on the heat-sealed area or exposed traces at the end of a flexible tail,
the migration of silver can occur. This will cause sometimes a short circuit.

13. Precautions for use
13-1. Installation of the LCD
1) The LCD shall be installed so that there is no pressure on the LSI chips.
2) The LCD shall be installed flat, without twisting or bending.
3) Must maintain a gap between inside of bezel and touch panel to avoid malfunction or electrode
damage of touch panel.
13-2. Static electricity
1) Since CMOS ICs are mounted directly onto the LCD glass, protection from static electricity
is required.
2) Workers should use body grounding. Operator should wear ground straps.
13-3. LCD operation
1) The LCD shall be operated within the limits specified. Operation at values outside of these limits
may shorten life, and/or harm display images.
13-4. Storage
1) The LCD shall be stored within the temperature and humidity limits specified.
Store in a dark area, and protect the LCD from direct sunlight or fluorescent light.
2) Always store the LCD so that it is free from external pressure onto it.
13-5. Usage
1) DO NOT store in a high humidity environment for extended periods. Polarizer degradation bubbles,
and/or peeling off of the polarizer may result.
2) Do not push or rub the touch panel's surface with hard to sharp objects such as knives, or the touch
panel may be scratched.
3) When the touch panel is dirty, gently wipe the surface with a soft cloth, sometimes moistened by mild
detergent or alcohol. If a hazardous chemical is dropped on the touch panel by mistake, wipe it off
right away to prevent human contact.
4) Touch panel edges are sharp. Handle the touch panel with enough care to prevent cuts
5) Always keep the LCD free from condensation during testing. Condensation may permanently spot
or stain the polarizer.
6) Do not disassemble LCD module because it will result in damage.
7) This Kyocera LCD module has been specifically designed for use in general electronic devices, but not
for use in a special environment such as usage in an active gas.Hence, when the LCD is supposed to
be used in a special environment, evaluate the LCD thoroughly beforehand and do not expose the
LCD to chemicals such as an active gas.
8) Please do not use solid-base image pattern for long hours because a temporary afterimage may
appear. We recommend using screen saver etc. in cases where a solid-base image pattern must
be used.
9) Liquid crystal may leak when the module is broken. Be careful not to let the fluid go into your eyes
and mouth. In the case the fluid touches your body; rinse it off right away with water and soap.
