How To Use LCD Module AN No.SIG-CHMO9805A

1. Safety

• If the LCD panel is damaged, be careful not to get the liquid crystal in your mouth and not to be injured by crushed glass.
• If you should swallow the liquid crystal , first wash your mouth thoroughly with water, then drink a lot of water induce vomiting and then consult a physician.
• If the liquid crystal should get in your eyes, flush your eyes with running water for at least fifteen minutes.
• If the liquid crystal touches your skin or clothes, remove it and wash the affected part of your skin or clothes with soap and running water.
• High voltage is applied to the lead terminals of the EL lamp. Do not touch any part of the lead terminals. (For LCD module with EL backlight)
• Do not use EL inverters without a load or in the short-circuit mode.
• Use the LCD module within the rated voltage to prevent overheating and/or damage. Also, take steps to ensure that the connector does not come off.

2. LCD Handling

• Please keep the temperature within the specified range for use and storage. Polarization degradation, bubble generation or polarizer peel-off may occur with high temperature and high humidity.
• Do not touch, push or rub the exposed polarizers with anything harder than hardness of 3B (glass, tweezers, etc..).
• When the display surface becomes dusty, wipe gently with absorbent cotton or other soft material like chamois soaked in petroleum benzene. Do not scrub hard to avoid damaging the display surface.
• Wipe off saliva or water drops immediately. Contact with water over a long period of time may cause deformation or color fading.
• Avoid contact with oil and fats.
• Condensation on the surface and contact terminals due to cold will damage, stain or dirty the polarizers. After products are tested at low temperatures they must be warmed up in a container before coming in contact with room temperature air.
• Do not put or attach anything on the display area to avoid leaving marks on.
• Do not touch the display area with bare hands, damage the display area and degrade insulation between terminals. (some cosmetics are detrimental to the polarizers)
• As glass is fragile, it tends to become cracked or chipped during handling especially on the edges, Please avoid dropping or jarring.

3. LCD Module

3.1 Mounting LCD module

• Use the specified mounting parts and holes to mount the module.
• Connect a 10 μF capacitor between the power supply terminals to eliminate noise.

Module

Screw

Fitting plate Transparent plate

Small gap

• Make sure that no stress is applied on the module when it is mounted. The application of stress for a long time may damage the LCD panel and the ICs substrates.
• To protect the polarizer and the LCD panel, cover the display surface with a transparent plate, for example, acrylic or glass, with a small gap between the transparent plate and the LCD surface.
• Do not apply input signals when power supply voltage isn't applied. 3.2 Precaution for handling LCD module Since the module has been assembled and adjusted with a high degree of precision, avoid applying excessive shocks to the module or making any modifications to it.
• Do not alter, modify or change the shape of the tab on the metal frame.
• Do not make extra holes on the PCB, modify its shape or change the positions of components attached.
• Do not damage or modify the pattern wiring on the PCB
• Do not modify the zebra rubber or touch it with another materials.
• Do not make any modifications with a soldering iron except indicating area.
• Do not drop, bend or twist the module. 3.3 Electro-static discharge Since CMOS ICs are mounted on the module, special attention has to be paid to the electric-static discharge.
• Make sure that you are connected to the ground during handling of the module.
• Before removing the module from packing unit make sure that the module and yourself have the same electric potential.
• When soldering the terminal of the module, make sure that the AC power source for the soldering iron does not leak.
• When using an electric screwdriver to attach the module, the screwdriver should be grounded to minimise as much as possible any transmission of electro-magnetic waves produced by sparks coming from the accumulator of the motor.
• Make your clothes and working bench the ground potential as much as possible.
• Avoid to generate static electricity, relative humidity should be 50 ~ 60 %RH. 3.4 Precaution for operation
• Proper operating voltage for LCD gives optimum viewing angle.
• If LCD surface is pressed harder during operation, the display becomes abnormal and then will return to normal after the pressure is released. However, it may generate bubbles and cause permanent damage to the LCD.
• Condensation may generate electrochemical reaction and then it may cause open or short circuit on the terminal. 3.5 Cleaning
• Do not wipe the polarizer with a dry cloth, as it may scratch the surface.
• Wipe the module gently with a soft cloth soaked with a petroleum benzene.
• Do not use ketonic solvents (ketone, acetone etc.) or aromatic solvents (toluene and xylenen) as they may damage the polarizing plate.

4. Storage

• Store the module in the dark place. Keep the temperature between 15 ºC and 35 ºC and the humidity below 65%RH.
• Do not store the module near organic solvents or corrosive gases.
• Make sure that no stress or vibration is applied to the module when it is stored.
• Use the products with EL backlight within 6 months after receiving them.
