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
AU OPTRONICS CORPORATION
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
electrostic breaddown.

Note 5： Definition of Average Luminance of White (YL):
Measure the luminance of gray level 63 at 5 points，Y
L (x) is corresponding to the luminance of the point X at Figure in Note (1).
Note 6： Definition of contrast ratio:
Note 7： Definition of Cross Talk (CT)
CT = | YB – YA | / YA × 100 (%)
www.jxlcd.com
www.jxlcd.com
Contrast ratio is calculated with the following formula.
= [L (1)+ L (2)+ L (3)+ L (4)+ L (5)] / 5
L
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
AU OPTRONICS CORPORATION
typically perpendicular to the display surface with the screen rotated about its center to develop the desired
measurement viewing angle.
