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) 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.
13) Disconnecting power supply before handling LCD modules, it can prevent electric shock, DO NOT TOUCH
the electrode parts, cables, connectors and LED circuit part of TFT module that a LED light bar build in as a
light source of back light unit. It can prevent electrostatic breakdown.

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, and it should be measured in
the center of screen

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.
