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 LED lightbar edge. Instead, press at the
far ends of the LED light bar 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) 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) Pls avoid touching COF position while you are doing mechanical design
14) When storing modules as spares for a long time, the following precaution is necessary:
Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep
the temperature between 5℃ and 35℃ at normal humidity.

2. General Description
Product Specification
AU OPTRONICS CORPORATION
G190EG02 VG
G190EG02 VG is aColor Active Matrix Liquid Crystal Display composed of a TFT-LC
D panel, a driver circuit,
and a backlight system. The screen format is intended to support the SXGA (1280(H) x 1024(V)) screen and
16.7M colors (RGB 6-bits + HiFRC data). All input signals are 2-channel LVDS interface compatible.
Inverter card of backlight is not included. M190EG02 V9 is designed for a display unit of personal
computer.

Note 1: Measurement method
The LCD module should be stabilized at given temperature for 30 minutes to avoid abrupt temperature
change during measuring (at surface 35). 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 2: Definition of viewing angle measured by ELDIM (EZContrast 88)
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.

temperature change. A cycle of rapid temperature change consists of varying the temperature from
-20℃ to 60℃, and back again. Power is not applied during the test. After temperature cycling, the
unit is placed in normal room ambient for at least 4 hours before power on.
