1. Handling Precautions
1) Since front polarizer is easily damaged, pay attention not to scratch it.
2) Be sure to turn off power supply when inserting or disconnecting from input connector.
3) Wipe off water drop immediately. Long contact with water may cause discoloration or spots.
4) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
5) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface.
6) Since CMOS LSI is used in this module, take care of static electricity and insure human earth
when handling.
7) Do not open or modify the Module Assembly.
8) Do not press the reflector sheet at the back of the module to any directions.
9) In case if a Module has to be put back into the packing container slot after once it was taken out
from the container, do not press the center of the CCFL reflector edge. Instead, press at the far
ends of the CCFL Reflector edge softly. Otherwise the TFT Module may be damaged.
10) At the insertion or removal of the Signal Interface Connector, be sure not to rotate nor tilt the
Interface Connector of the TFT Module.
11) After installation of the TFT Module into an enclosure, do not twist nor bend the TFT Module
even momentary. At designing the enclosure, it should be taken into consideration that no
bending/twisting forces are applied to the TFT Module from outside. Otherwise the TFT Module
may be damaged.
12) Cold cathode fluorescent lamp in LCD contains a small amount of mercury. Please follow local
ordinances or regulations for disposal.
13) Small amount of materials having no flammability grade is used in the LCD module. The LCD module
should be supplied by power complied with requirements of Limited Power Source (IEC60950 or
UL1950), or be applied exemption.
14) The LCD module is designed so that the CCFL in it is supplied by Limited Current Circuit (IEC60950 or
UL1950). Do not connect the CCFL in Hazardous Voltage Circuit.

Note 1: Definition of viewing angle
Viewing angle is the measurement of contrast ratio ≧10, at the screen center, over a 180° horizontal and
180° vertical range (off-normal viewing angles). The 180° viewing angle range is broken down as follows;
90° (θ) horizontal left and right and 90° (Φ) vertical, high (up) and low (down). The measurement direction
is typically perpendicular to the display surface with the screen rotated about its center to develop the
desired measurement viewing angle.

*3 In designing an inverter, it is suggested to check safety circuit very carefully. Impedance of
CCFL, for instance, becomes more than 1 [M ohm] when CCFL is damaged.
*4 Generally, CCFL has some amount of delay time after applying kick-off voltage. It is
recommended to keep on applying kick-off voltage for 1 [Sec] until discharge.
*5 Reducing CCFL current increases CCFL discharge voltage and generally increases CCFL
discharge frequency. So all the parameters of an inverter should be carefully designed so as
not to produce too much leakage current from high-voltage output of the inverter.
Note 2: It should be employed the inverter which has “Duty Dimming”, if IRCFL is less than 3mA.
Note 3: CCFL discharge frequency should be carefully determined to avoid interference between inverter
and TFT LCD.
Note 4: The frequency range will not affect to lamp life and reliability characteristics.
Note 5: CCFL inverter should be able to give out a power that has a generating capacity of over 1,700
voltage. Lamp units need 1,700 voltage minimum for ignition.
Note 6: The variance of CCFL power consumption is ±10%. Calculator value for reference (ISCFL × VCFL
× 2 = PCFL)

Note 7: Definition of life: brightness becomes 50%. The typical life time of CCFL is under the condition at
7.5 mA lamp current.
Note 8: The CCFL can work normally if the PWM Dimming ratio range is from 20% to 100% and the lamp
current is 7.5mA.
