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) 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 3: The luminance uniformity of 5 or13 points is defined by dividing the maximum luminance values by the
minimum test point luminance
Maximum Brightness of five points
W5 =
Minimum Brightness of five points
Maximum Brightness of thirteen points
W13 =
Minimum Brightness of thirteen points
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

Note 5 Definition of Average Luminance of White (YL):
Measure the luminance of gray level 63 at 5 points YL = [L (1)+ L (2)+ L (3)+ L (4)+ L (5)] / 5
L (x) is corresponding to the luminance of the point X at Figure in Note (1).
Note 6 Definition of contrast ratio:
Contrast ratio is calculated with the following formula.
Brightness on the "White" state
Contrast ratio (CR)=
Brightness on the "Black" state
