1. Handling Precautions
1) Since front polarizer is easily damaged, please be cautious and 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 soft cloth.
5) Since the panel is made of glass, it may be broken or cracked if dropped or bumped on hard
surface.
6) To avoid ESD (Electro Static Discharde) damage, be sure to ground yourself before handling
TFT-LCD Module.
7) Do not open nor modify the module assembly.
8) Do not press the reflector sheet at the back of the module to any direction.
9) In case if a module has to be put back into the packing container slot after it was taken out from
the container, do not press the center of the LED light bar 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) TFT-LCD Module is not allowed to be twisted & bent even force is added on module in a very short
time. Please design your display product well to avoid external force applying to module by end-user
directly.
12) Small amount of materials without flammability grade are used in the TFT-LCD module. The
TFT-LCD module should be supplied by power complied with requirements of Limited Power Source
(IEC60950 or UL1950), or be applied exemption.
13) Severe temperature condition may result in different luminance, response time and lamp ignition
voltage.
14) Continuous operating TFT-LCD display under low temperature environment may accelerate lamp
exhaustion and reduce luminance dramatically.
15) The data on this specification sheet is applicable when LCD module is placed in landscape position.
16) Continuous displaying fixed pattern may induce image sticking. It’s recommended to use screen
saver or shuffle content periodically if fixed pattern is displayed on the screen.

Note 1: Definition of viewing angle
Viewing angle is the measurement of contrast ratioЊ10, or Њ5, 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 (Ӱ)
horizontal left and right and 90 (ӥ) 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.
G190ETN01.2
Note 2: 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. ʳ

Note 3: Definition of response time:
The output signals of photo detector are measured when the input signals are changed from “Full Black” to “Full
White” (rising time), and from “Full White” to “Full Black” (falling time), respectively. The response time is interval
between the 10% and 90% of amplitudes. Please refer to the figure as below.
