10 / 11 page  9 Precautions Safety Instructions • If the LCD panel is damaged, be careful not to get the liquid crystal in your mouth and not to be injured by crushed glasses. • 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. • If the liquid crystal should get in your eye, flush your eye with running water for at least fifteen minutes. • If the liquid crystal touches your skin or clothes, re- move it and wash the affected part of your skin or clothes with soap and running water. • EL or CFL backlight is driven by a high voltage with an inverter. Do not touch the connection part or the wir- ing pattern of the inverter. • Do not use inverters without a load or in the short-cir- cuit mode. • Use the LCD module within the rated voltage to pre- vent overheating and/or damage. Also, take steps to ensure that the connector does not come off. Handling Precautions • Since the LCD panel has glass substrate, avoid apply- ing mechanical shock or pressure on the module. Do not drop, bend, twist or press the module. • Do not soil or damage LCD panel terminals. • Since the polarizer is made of easily-scratched mate- rial, be careful not to touch or place objects on the dis- play surface. • Keep the display surface clean. Do not touch it with your skin. • CMOS LSI is used in the LCD module. Be careful of static electricity. • Do not disassemble the module or remove the liquid crystal panel or the panel frame. • Do not damage the film surface of the EL lamp; other- wise the lamp will be damaged by humidity. • To set an EL lamp in an LCD module, push the EL lamp with its emitting side up, without pushing the rub- ber connectors too hard. If you damage them, the LCD module may not work properly. Mounting and Designing • To protect the polarizer and the LCD 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. • Keep the module dry. Avoid condensation to prevent the transparent electrodes from being damaged. • Drive LCD panel with AC waveform in which DC ele- ment is not included to prevent deterioration in the LCD panel. • Contrast of LCD varies depending on the ambient tem- perature. To offer the optimum contrast, LC drive volt- age should be adjusted. LCD driven in a high duty ratio must be provided with drive voltage adjustment method. • Mount a LCD module with the specified mounting part/ holes. • Design the equipment so that input signal is not ap- plied to the LCD module while power supply voltage is not applied to it. • Do not locate the CFL tube and the lamp lead wire close to a metal plate or a plated part inside the equip- ment. Otherwise stray capacity causes a drop in volt- age, decreasing the brightness and the ability to start- up. Cleaning • Do not wipe the polarizer with a dry cloth, as it may scratch the surface. • Wipe the LCD panel gently with a soft cloth soaked with a petroleum benzine. • Do not use ketonic solvents (ketone and acetone)or aromatic solvents (toluene and xylene), as they may damage the polarizer. Storing • Store the LCD panel in a dark place, where the tem- perature is 25 °C±10°C and the relative humidity be- low 65%. If possible, store the LCD panel in the pack- aging situation when it was delivered. • Do not store the module near organic solvents or cor- rosive gases. • Keep the module (including accessories) safe from vi- bration, shock and pressure. • Use an LCD module with built-in EL backlight within six months of delivery. • EL backlight is easily affected by environmental con- ditions such as temperature and humidity; the quality may deteriorate if stored for an extended period of time. Contact Seiko Instruments GmbH for details. • Some parts of the backlight and the inverter generate heat. Take care so that the heat does not affect the liquid crystal or any other parts. • Dust particles attached to the surface of the LCD or the surface of the backlight degrade the display qual- ity. Be careful to keep dust out in designing the struc- ture as well as in handling the module. • Black or white air-bubbles may be produced if the LCD panel is stored for long time in the lower temperature or mechanical shocks are applied onto the LCD panel.
