◆Operating precautions

･Do not connect it to or disconnect it from the main system when the LCD module is powered

on.

･If the LCD module is stored at temperatures below or above the specified storage

temperature limits, it may be malfunction and it may not be restored even after the

temperature is adjusted to the specified storage temperature.

･Optical characteristics (viewing angle and contrast ratio) are depended on LCD driving

voltage. Please adjust it to achieve optimum contrast ratio in each module.

Driving voltage (VDD‑Vo):

GMF12064ASLY, GMF25012GBTW, GMF25012HBTW, GMF32024ABTW,

GMF32024BSLY, GMF32024HBTW, GMF32024HFTW, GMF64020ABTW

Driving voltage (VEE‑VSS):

GMF32024JBTW, GMF32124JBTW, GMF32024JFTW,

GMF32124JFTW, GMF32024KFTW, GMF32124KFTW

･Do not use the module in dewy, a lot of moisture, or other solutions.

If even slight condensation occurs or splashes solutions at the terminals of LCD panel,

electrochemical reactions will occur on the terminals, and terminal may be damaged and

disconnected. Please note to prevent rapid temperature changes, because it may causes

condensation.

･Do not touch the connector terminals, PWB, and electronic components when the LCD module

is operating. Especially CCFL connectors are applied high voltage, and there is a danger

of the electric shock.

Touching them may also cause malfunction of LCD module.

･Each product is designed to operate at specified driving duty ratio. If it is operated

at a different duty ratio, it may be malfunction.

1/64 duty drive: GMF12064ASLY

1/128 duty drive: GMF25012GBTW, GMF25012HBTW

1/200 duty drive: GMF64020ABTW

1/240 duty drive: GMF32024ABTW, GMF32024BSLY, GMF32024HBTW, GMF32024HFTW,

GMF32024JBTW, GMF32124JBTW, GMF32024JFTW, GMF32124JFTW,

GMF32024KFTW, GMF32124KFTW

･When LC panel is applied the DC voltage, its lifetime is shortened rapidly by

electrochemical reaction. When using the GMF series LCD module, keep following power

supply sequence to prevent the DC voltage being applied to the panel and to prevent

the latch‑up of CMOS‑LSI in the module.

If the LC driving voltage or various signals are input before the logic power supply

is stabilized, the internal LSI may be damaged due to floating or latch‑up phenomena.
