11. General Precautions

(a) When the module is assembled, it should be attached to the system firmly

(e) If the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth

(g) If the liquid crystal material leaks from the panel

should be kept

away

using all mounting holes. Be careful not to twist and bend the module.

(b) Refrain from strong mechanical shock and / or any force to the module.

In addition to damage, it may cause improper operation or damage to the module
and LED back light.

(c) Note that polarizer films are very fragile and could be damaged easily.

Do not press or scratch the surface harder than a HB pencil lead.

(d) Wipe off water droplets or oil immediately. If you leave the droplets for a long

time, staining or discoloration may occur.

.

(f) Desirable cleaners are water, IPA (Isopropyl Alcohol) or Hexane.

Do not use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid
or Methyl chloride. It might cause permanent damage to the polarizer due to chemical
reaction.

, it
from the eyes or mouth . In case of contact with hands, legs or clothes, it must
be washed away with soap thoroughly.

(h) Protect the Module from static, or the CMOS Gate Array IC would be damaged.

(i) Use finger-stalls with soft gloves in order to keep display clean during the

ncoming inspection and assembly process.

(j) Do not disassemble the Module.

(k) Protection film for polarizer on the Module should be slowly peeled off just before use

so that the electrostatic charge can be minimized.

(l) Pins of I/F connector should not be touched directly with bare hands.

11.4 Operation Condition Guide

(a) The LCD product should be operated under normal conditions.

Normal condition is defined as below;

- Temperature : 20±15℃

- Humidity : 65±20%

- Display pattern : continually changing pattern (Not stationary)

(b) If the product will be used in extreme conditions such as high temperature,

humidity, display patterns or operation time etc.., It is strongly recommended
to contact SEC for Application engineering advice. Otherwise, its reliability and
function may not be guaranteed. Extreme conditions are commonly found at

Airports, Transit Stations, Banks, Stock market, and Controlling systems.

11.5 Others

condensation of water. It may result in improper operation or disconnection

of electrode.

(c) Do not exceed the absolute maximum rating value. ( supply voltage variation,

input voltage variation, variation in part contents and environmental temperature,
and so on)

.

(d) If the Module keeps displaying the same pattern for a long period of time,

the image may be "sticked" to the screen.
To avoid image sticking, it is recommended to use a screen saver.
