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 nor 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 LED Reflector edge. Instead, press at the far ends
of the CFL 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 (Notebook PC Bezel, for example), 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 LED in it is supplied by Limited Current Circuit (IEC60950 or
UL1950). Do not connect the LED in Hazardous Voltage Circuit.

Note 4: Measurement method
The LCD module should be stabilized at given temperature for 30 minutes to avoid abrupt temperature
change during measuring. In order to stabilize the luminance, the measurement should be executed
after lighting Backlight for 30 minutes in a stable, windless and dark room.

Note 7: Definition of Cross Talk (CT)
CT = | YB – YA | / YA × 100 (%)
Where
YA = Luminance of measured location without gray level 0 pattern (cd/m2)
YB = Luminance of measured location with gray level 0 pattern (cd/m2)

Note 8: Definition of response time:
The output signals of BM-7 or equivalent are measured when the input signals are changed from
“Black” to “White” (falling time) and from “White” to “Black” (rising time), respectively. The response
time interval between the 10% and 90% of amplitudes. Refer to figure as below.

Note 9: 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.
