1. PREAUTIONS 1.1 Handling the LD Module Safety Ÿ If the LD panel is damaged, be careful not to get the liquid crystal in your mouth and not to be injured by crushed glasses. Ÿ If you should swallow the liquid crystal, first, wash your mouth thoroughly with water, then ; drink a lot of water and induce vomiting ; and then, consult a physician. Ÿ If the liquid crystal should get in your eye, flush your eye with running water for at least fifteen minutes. Ÿ 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. Ÿ High is applied to the lead terminals of the EL lamp. Do not touch any part of the lead terminals. (For LD modules with EL backlight) Ÿ Do not use EL inverters without a load or in the short-circuit mode. Ÿ Use the LD module within the rated to prevent overheating and/or damage. Also, take steps to ensure that the connector does not come off. Ÿ Keep the display surface clean. Do not touch it with your skin. Mounting and design Ÿ Use the specified mounting parts and holes to mount the module. Ÿ Make sure that no stress is applied on the module when it is mounted ; stress applied for a long time may damage the LD panel and the I substrates. Ÿ onnect a 10-µF capacitor between the power supply terminals to eliminate noise. Ÿ To protect the polarizer and the LD panel, cover the display surface with a transparent plate (e.g., acrylic or glass) with a small gap between the transparent plate and the display surface. YExample Ÿ Do not apply input signals when power supply is not applied. Ÿ Avoid condensation, or the transparent electrodes may break. Use the module within the specified temperature range. Handling Ÿ Avoid static electricity, as it may damage MOS LSIs mounted on the module.. Ÿ Since the LD panel has glass substrate, avoid applying mechanical shock or pressure on the module. Do not drop, bend, twist or press the module. Ÿ Do not disassemble the module. Ÿ Since the polarizer is made of easilyscratched material, be careful not to touch or place objects on the display surface. 7 Storage Ÿ Store the module in a dark place, where the temperature is 5 10 and the relative humidity below 65%. If possible, store the module in the packaging situation when it was delivered. Ÿ Do not store the module near organic solvents or corrosive gases. Ÿ Keep the module (including accessories) safe from vibration, shock and pressure. Ÿ Use the products within 6 months of receiving it. (For LD modules with EL backlight)
Ÿ Because the EL backlight uses organic materials that are very sensitive to heat and humidity, there may be some loss of quality when stored for long periods of time. ontact SII for further detail. Ÿ Black or white air-bubbles may be produced if the module is stored for a long time in the lower temperature or mechanical shocks are applied onto the module. Ÿ To set an EL lamp in an LD module, push the EL lamp with its emitting side up, without pushing the rubber connectors too hard. If you damage them, the LD module may not work properly. Ÿ Do not damage the film surface of the EL lamp ; otherwise the lamp will be damaged by humidity. leaning Ÿ Do not wipe the polarizer with a dry cloth, as it may scratch the surface. Ÿ Wipe the module gently with a soft cloth soaked with a petroleum benzine. Ÿ Do not use keic solvents (kee and acee) or aromatic solvents (toluene and xylene), as they may damage the polarizer. 1. Handling the LED Backlight Ÿ When soldering the connector for LED backlight unit, the soldering iron temperature should not exceed 60, and soldering time should be within 3 seconds. (L1681, L167, L169, L03, L4051, L405) Ÿ For cleaning, wipe with soft cloth and use only the following chemicals. Ÿ Ethanol Ÿ Isopropyl alcohol 1.3 Mounting of an EL Lamp and an Inverter ŸYour design should make it easy to replace EL lamps since they have a shorter service life than the other components of LD modules. Ÿ Do not bend the EL leads when soldering them on the circuit board of the LD modules ; otherwise they may break. 8
