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 light emitting diode Lamp (LED)
reflector edge. Instead, press at the far ends of the LED 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) light emitting diode Lamp (LED) 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 1: Definition of viewing angle
Viewing angle is the measurement of contrast ratio≧10, or ≧5, 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.
Note 2: 9 points position
Note 3: The luminance uniformity of 9 points is defined by dividing the maximum luminance values by the
minimum test point luminance

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 1: Typ. are AUO recommended design points.
*1 All of characteristics listed are measured under the condition using the AUO test inverter.
*2 In case of using an inverter other than listed, it is recommended to check the inverter carefully.
Sometimes, interfering noise stripes appear on the screen, and substandard luminance or flicker
at low power may happen.
*3 In designing an inverter, it is suggested to check safety circuit very carefully. Impedance of LED
, for instance, becomes more than 1 [M ohm] when LED is damaged.
*4 Generally, LED 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 LED current increases LED discharge voltage and generally increases LED
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: LED standard current is measured at 25±2℃.
Note 3: LED 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: LED inverter should be able to give Constant current.
Note 6: The variance of LED power consumption is ±10%. Calculator value for reference (ISLED × VLED × 2
= PLED)
Note 7: Definition of life: brightness becomes 50%. The typical life time of LED is on the condition at 250
mA lamp current.
