PRECAUTIONS FOR USING

6.1 Handling Precautions

This device is susceptible to Electro-Static Discharge (ESD) damage. Observe Anti-Static precautions.
SuR display panel is made of glass. Do not subject it to a mechanical shock by dropping it or impact. If
SUR 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.
Do not apply excessive force to the SuR display surface or the adjoining areas since this may cause the color tone to vary.
The polarizer covering the SUR display surface of the LCD module is soft and easily scratched. Handle this polarizer carefully.
If SuR display surface becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is heavily contaminated, moisten cloth with one of the following Isopropyl or alcohol.
Solvents other than those above-mentioned may damage the polarizer. Especially, do not use the Water.
Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets, moisture condensation or a current flow in a high-humidity environment.
Install the SUR 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 cable or the backlight cable.
Do not attempt to disassemble or process SuR LCD module.
NC terminal should be open. Do not connect anything.
If the logic circuit power is off, do not apply the input signals.
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 suR LCD modules. -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. -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.

6.2 Power Supply Precautions

Identify and, at all times, observe absolute maximum ratings for both logic and LC drivers. Note that there is some variance between models.
Prevent the application of reverse polarity to VDD and VSS, however briefly.
Use a clean power source free from transients. Power-up conditions are occasionally jolting and may exceed the maximum ratings of SURmodules.
The VDD power of module should also supply the power to all devices that may access the SUR display. Don’t allow the data bus to be driven when the logic supply to the module is turned off. 43B340B337B43B

6.3 Operating Precautions

DO NOT plug or unplug module when the system is powered up.
Minimize the cable length between module and host MPU.
For models with backlights, do not disable the backlight by interrupting the HV line. Unload inverters produce voltage extremes that may arc within a cable or at the display.
Operate module within the limits of the modules temperature specifications.

6.4 Mechanical/Environmental Precautions

Improper soldering is the major cause of module difficulty. Use of flux cleaner is not recommended as they may seep under the electrometric connection and cause display failure.
Mount module so that it is free from torque and mechanical stress. SUR
Surface of the LCD panel should not be touched or scratched. The display front surface is an easily scratched, plastic polarizer. Avoid contact and clean only when necessary with soft, absorbent cotton dampened with petroleum benzene.
Always employ anti-static procedure while handling SUR module.
Prevent moisture build-up upon the module and observe the environmental constraints for storage tem
Do not store in direct sunlight
If leakage of the liquid crystal material should occur, avoid contact with this material, particularly ingestion. If the body or clothing becomes contaminated by the liquid crystal material, wash thoroughly with water and soap

6.5 Storage Precautions
When storing the LCD modules, avoid exposure to direct sunlight or to the light of fluorescent lamps.
Keep modules in bags (avoid high temperature / high humidity and low temperatures below 0C SUR SUR Whenever possible, LCD modules should be stored in the same conditions in which they were shipped from our company. 458B362B455B359B452B356B
6.6 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 LCD modules have been operating for a long time showing the same display patterns, the display SUR patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear. A normal operating status can be regained 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 modules 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.

USING LCD MODULES

7.1 Liquid Crystal Display Modules
LCD is composed of glass and polarizer. Pay attention to the following items when handling.

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.
Do not touch, push or rub the exposed polarizers with anything harder than an HB pencil lead (glass, tweezers, etc.).
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, ethanol and isopropylalcohol.
When SUR display surface becomes dusty, wipe gently with absorbent cotton or other soft material like chamois soaked in petroleum benzin. 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 contacting oil and fats.
Condensation on the surface and contact with terminals due to cold will damage, stain or dirty the polarizers. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air.
Do not put or attach anything on SUR display area to avoid leaving marks on.
Do not touch the display with bare hands. This will stain the display area and degradate insulation between terminals (some cosmetics are determinated to the polarizers).
As glass is fragile. It tends to become or chipped during handling especially on the edges. Please avoid dropping or jarring.

7.2 Installing LCD Modules

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

7.3 Precaution for Handling LCD Modules Since SUR
LCM has been assembled and adjusted with a high degree of precision; avoid applying excessive shocks to the module or making any alterations or 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 printed circuit board, modify its shape or change the positions of components to be attached.
Do not damage or modify the pattern writing on the printed circuit board.
Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal connector.
Except for soldering the interface, do not make any alterations or modifications with a soldering iron.
Do not drop, bend or twist LCM.

7.4 Electro-Static Discharge Control
Since this module uses a CMOS LSI, the same careful attention should be paid to electrostatic discharge as for an ordinary CMOS IC.

Make certain that you are grounded when handing LCM.
Before remove LCM from its packing case or incorporating it into a set, be sure the module and your body have the same electric potential.
When soldering the terminal of LCM, make certain the AC power source for the soldering iron does not leak.
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.
As far as possible make the electric potential of your work clothes and that of the work bench the ground potential.
To reduce the generation of static electricity be careful that the air in the work is not too dried. A relative humidity of 50%-60% is recommended.

7.5 Precaution for Soldering to LCM

Observe the following when soldering lead wire, connector cable and etc. to the LCM.
-Soldering iron temperature : 280℃±10℃
-Soldering time: 3-4 sec.
SUR -Solder: eutectic solder.
If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation. (This does not apply in the case of a non- halogen type of flux.) It is recommended that you protect the LCD surface with a cover during soldering to prevent any damage due to flux spatters.
When soldering the electroluminescent panel and PC board, the panel and board should not be detached more than three times. This maximum number is determined by the temperature and time conditions mentioned above, though there may be some variance depending on the temperature of the soldering iron.
When remove the electroluminescent panel from the PC board, be sure the solder has completely melted, the soldered pad on the PC board could be damaged.

7.6 Precaution for Operation

Viewing angle varies with the change of liquid crystal driving voltage (VO). Adjust VO to show the best contrast.
Driving the SUR LCD in the voltage above the limit shortens its life.
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.
If SUR 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 back on.
Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit. Therefore, it must be used under the relative condition of 40℃, 50% RH.
When turning the power on, input each signal after the positive/negative voltage becomes stable.

7.7 Limited Warranty
Unless agreed between SUR and customer, SUR SUR will replace or repair any of its LCD modules which are found to be functionally defective when inspected in accordance with LCD acceptance standards (copies available upon request) for a period of one year from date of shipments. Cosmetic/visual defects must be returned to SUR SUR within 90 days of shipment. Confirmation of such date shall be based on freight documents. The warranty liability of limited to repair and/or replacement on the terms set forth above. SUR will not be responsible for any subsequent or consequential events.
7.8 Return Policy
No warranty can be granted if the precautions stated above have been disregarded. The typical examples of violations are:
-Broken LCD glass.
-PCB eyelet damaged or modified.
-PCB conductors damaged.
-Circuit modified in any way, including addition of components.
-PCB tampered with by grinding, engraving or painting varnish.
-Soldering to or modifying the bezel in any manner.
Module repairs will be invoiced to the customer upon mutual agreement. Modules must be returned with sufficient description of the failures or defects. Any connectors or cable installed by the customer must be removed completely without damaging the PCB eyelet’s, conductors and terminals That’s the end of the datasheet
