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 indemnify, 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

11. Precautions for use
11-1. Installation of the LCD
1) Please ground either of the mounting (screw) holes located at each corner of an LCD,
in order to stabilize brightness and display quality.
2) A transparent protection plate shall be added to protect the LCD and its polarizer.
3) The LCD shall be installed so that there is no pressure on the LSI chips.
4) The LCD shall be installed flat, without twisting or bending.
11-2. 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.
11-3. 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.
11-4. 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.
11-5. 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) The front polarizer is easily scratched or damaged. Prevent touching it with any hard material, and
from being pushed or rubbed.
3) The LCD screen may be cleaned by wiping the screen surface with a soft cloth or cotton pad using a
little Ethanol.
4) Water may cause damage or discoloration of the polarizer. Clean condensation or moisture from
any source immediately.
5) Always keep the LCD free from condensation during testing. Condensation may permanently spot
or stain the polarizer.
6) Do not disassemble LCD because it will result in damage.
7) This Kyocera LCD 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 LCD 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.

1) Each test item uses a test LCD only once. The tested LCD is not used in any other tests.
2) The LCD is tested in circumstances in which there is no condensation.
3) The reliability test is not an out-going inspection.
4) The result of the reliability test is for your reference purpose only.
The reliability test is conducted only to examine the LCD's capability.
