10. PRECAUTIONS FOR USING LCD MODULES

10.1. HANDLING PRECAUTIONS

(1) The display panel is made of glass. Do not subject it to a mechanical shock or impact by dropping

it.

(2) If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in

your mouth. If the substance contacts your skin or clothes, wash it off using soap and water.

(3) Do not apply excessive force to the display surface or the adjoining areas since this may cause the

color tone to vary.

(4) The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle

this polarizer carefully.

(5) If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft

dry cloth. If it is heavily contaminated, moisten a cloth with one of the following solvents:

- Isopropyl alcohol

- Ethyl alcohol

(6) Solvents other than those above mentioned may damage the polarizer.

Especially, do not use the following:

- Water

- Ketone

- Aromatic solvents

(7) Extra care to minimize corrosion of the electrode. Water droplets, moisture condensation or a

current flow in a high-humidity environment accelerates corrosion of the electrode.

(8) Install the LCD Module by using the mounting holes. When mounting the LCD Module, make

sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O

cable or the backlight cable.

(9) Do not attempt to disassemble or process the LCD Module.

(10) NC terminal should be open. Do not connect anything.

(11) If the logic circuit power is off, do not apply the input signals.

(12) To prevent destruction of the elements by static electricity, be careful to maintain an optimum

work environment.

- Be sure to ground the body when handling he LCD Module.

- Tools required for assembling, such as soldering irons, must be properly grounded.

-To reduce the amount of static electricity generated, do not conduct assembling and other work

under dry conditions.

GB12864B

VER: 3.0

- 17 -

Issue date: 2006/08/01

JEWEL HILL ELECTRONIC CO.,LTD.

-The LCD Module is coated with a film to protect the display surface. Exercise care when peeling

off this protective film since static electricity may be generated.

10.2. STORAGE CONDITIONS

When storing, avoid the LCD module to be exposed to direct sunlight of fluorescent lamps. For

stability, to keep it away form high temperature and high humidity environment (The best condition

is : 23±5°C, 45±20%RH). ESD protection is necessary for long-term storage also.

10.3. OTHERS

Liquid crystals solidify under low temperature (below the storage temperature range) leading to

defective orientation or the generation of air bubbles (black or white). Air bubbles may also be

generated if the module is subject to a low temperature.

If the LCD Module have been operating for a long time showing the same display patterns the display

patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear.

A normal operating status can be recovered by suspending use for some time. It should be noted that

this phenomenon does not adversely affect performance reliability.

To minimize the performance degradation of the LCD Module resulting from destruction caused by

static electricity etc. exercise care to avoid holding the following sections when handling the modules.

Exposed area of the printed circuit board.

Terminal electrode sections.

11. Using LCD modules

11.1 LIQUID CRYSTAL DISPLAY MODULES

LCD is composed of glass and polarizer. Pay attention to the following items when handling.

(1) Please keep the temperature within specified range for use and storage. Polarization degradation,

bubble generation or polarizer peel-off may occur with high temperature and high humidity.

(2) Do not touch, push or rub the exposed polarizers with anything harder than a HB pencil lead (glass,

tweezers, etc).

(3) N-hexane is recommended for cleaning the adhesives used to attach front/rear polarizers and

reflectors made of organic substances, which will be damaged by chemicals such as acetone,

toluene, toluene, ethanol and isopropyl alcohol.

(4) When the display surface becomes dusty, wipe gently with absorbent cotton or other soft material

like chamois soaked in petroleum ether. Do not scrub hard to avoid damaging the display surface.

(5) Wipe off saliva or water drops immediately, contact with water over a long period of time may

cause deformation or color fading.

(6) Avoid contacting oil and fats.

(7) Condensation on the surface and contact with terminals due to cold will damage, stain or

polarizers. After products are tested at low temperature they must be warmed up in a container

before coming is contacting with room temperature air.

(8) Do not put or attach anything on the display area to avoid leaving marks on.

(9) Do not touch the display with bare hands. This will stain the display area and degrade insulation

between terminals (some cosmetics are determinate to the polarizers).

(10)As glass is fragile, it tends to become or chipped during handling especially on the edges. Please

avoid dropping or jarring.

11.2 INSTALLING LCD MODULE

Attend to the following items when installing the LCM.

(1) Cover the surface with a transparent protective plate to protect the polarizer and LC cell.

(2) When assembling the LCM into other equipment, the spacer to the bit between the LCM and the

fitting plate should have enough height to avoid causing stress to the module surface, refer to the

individual specifications for measurements. The measurement tolerance should be ±0.1mm.

11.3 ELECTRO-STATIC DISCHARGE CONTROL

Since this module uses a CMOS LSI, the same careful attention should be paid for electrostatic

discharge as for an ordinary CMOS IC.

GB12864B

VER: 3.0

- 19 -

Issue date: 2006/08/01

JEWEL HILL ELECTRONIC CO.,LTD.

(1) Make certain that you are grounded when handing LCM.

(2) Before removing LCM from its packing case or incorporating it into a set, be sure the module and

your body have the same electric potential.

(3) When soldering the terminal of LCM, make certain the AC power source for the soldering iron

does not leak.

(4) When using an electric screwdriver to attach LCM, the screwdriver should be of ground

potentiality to minimize as much as possible any transmission of electromagnetic waves produced

sparks coming from the commutator of the motor.

(5) As far as possible, make the electric potential of your work clothes and that of the workbenches to

the ground potential.

(6) To reduce the generation of electro-static discharge, be careful that the air in the work is not too

dried. A relative humidity of 50%-60% is recommended.

11.4 PRECAUTIONS FOR OPERATION

(1) Viewing angle varies with the change of liquid crystal driving voltage (Vo). Adjust Vo to show

the best contrast.

(2) Driving the LCD in the voltage above the limit will shorten its lifetime.

(3) Response time is greatly delayed at temperature below the operating temperature range. However,

this does not mean the LCD will be out of the order. It will recover when it returns to the specified

temperature range.

(4) If the display area is pushed hard during operation, the display will become abnormal. However, it

will return to normal if it is turned off and then on.

(5) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit.

Therefore, this product must be used and stored within the specified condition of 23±5°C,

45±20%RH.

(6) When turning the power on, input each signal after the positive/negative voltage becomes stable.

11.5 SAFETY

(1) It is recommended to crush damaged or unnecessary LCDs into pieces and wash them off with

solvents such as acetone and ethanol, which should later be burned.

(2) If any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash off

thoroughly with soap and water.
