Note (1) Measurement Setup:
The LCD module should be stabilized at given temperature(25℃) for 15 minutes to
Avoid abrupt temperature change during measuring. In order to stabilize the luminance,
the measurement should be executed after lighting backlight for 15 minutes in a
windless room.

(1) Please mount LCD module by using mounting holes arranged in four corners tightly.
(2) Do not disassemble or modify the module. It may damage sensitive parts inside LCD
module, and may cause scratches or dust on the display. KYD does not warrant the
module, if customers disassemble or modify the module.
(3) If LCD panel is broken and liquid crystal spills out, do not ingest or inhale liquid Crystal,
and do not contact liquid crystal with skin. If liquid crystal contacts mouth or eyes, rinse
out with water immediately. If liquid crystal contacts skin or cloths, wash it off
immediately with alcohol and Rinse thoroughly with water.
(4) Disconnect power supply before handling LCD module
(5) Refrain from strong mechanical shock and /or any force to the module.
(6) Do not exceed the absolute maximum rating values, such as the supply voltage
variation, input voltage variation, variation in parts’ parameters, environmental
temperature; etc otherwise LCD module may be damaged. It’s recommended
employing protection circuit for power supply.
(7) Do not touch, push or rub the polarizer with anything harder than HB pencil lead. Use
fingerstalls of soft gloves in order to keep clean display quality, when Persons handle
the LCD module for incoming inspection or assembly.
(8) When the surface is dusty, please wipe gently with absorbent cotton or other soft
Material. When cleaning the adhesives, please use absorbent cotton wetted with a little
Petroleum benzene or other adequate solvent.
(9) Wipe off saliva or water drops as soon as possible. If saliva or water drops Contact with
polarizer for a long time, they may causes deformation or color Fading.

(10) Protection film must remove very slowly from the surface of LCD module to
Prevent from electrostatic occurrence.
(11) Because LCD module uses CMOS-IC on circuit board and TFT-LCD panel, it is Very
weak to electrostatic discharge, Please be careful with electrostatic
Discharge .Persons who handle the module should be grounded through adequate
methods.
(12) Do not adjust the variable resistor located on the module.
13.3 Storage Precaution
(1) Please do not leave LCD module in the environment of high humidity and high
temperature for a long time.
(2) The module shall not be exposed under strong light such as direct sunlight.Otherwise,
Display characteristics may be changed.
(3) The module should be stored in a dark place. It is prohibited to apply sunlight or
fluorescent light in storage.
13.4 Operation Precaution
(1) Do not connect or disconnect the module in the "Power On” condition.
(2) Power supply should always be turned on/off by 9.0 "Power on/off sequence"
(3) Module has high frequency circuits. Sufficient suppression to the electromagnetic
interference should be done by system manufacturers. Grounding and shielding
methods may be important to minimize the interference.
(4) 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.
13.5 Others
(1) Ultra-violet ray filter is necessary for outdoor operation.
(2) Avoid condensation of water which may result in improper operation or disconnection of
electrode.
(3) If the module keeps displaying the same pattern for a long period of time, the image
may be "sticked" to the screen.
(4) This module has its circuitry PCB's on the rear side and should be handled carefully in
order not to be stressed.
13.6 Disposal
When disposing LCD module, obey the local environmental regulations.
