Do not touch TCP area: 

Do not touch TCP area at any 

case. It can cause Driver IC cracks, film cracks, etc. The 
TCP is the weakest point of the LCD Module.

Do not pull Backlight wire: 

Please do not pull the 

Backlight wire, as it can cause the wire to become 
disconnected or damaged.

Check the connections of the Inverter & Backlight 
connectors: 

Incomplete connection can cause burnt in 

Backlight connectors or damage the inverter.

Handle with care:

Please do not drop, bend, or hit the LCD Module.

Physical stress can cause defects as broken panels.

Keep mounting screw length and motor driver’s 
torque: 

Strong motor driver’s torque can make a 

mechanical defect on LCD Module. Please keep within the 
specifications.

Do not operate for a long time under the same pattern: 

Operating the LCD Module for a long time with the same 
video pattern can cause image persistence and can 
eventually damage it.

Defective panels must also be handled with care:

To prevent making other defects, please handle the 
defective LCD Module as a good one.

Defective LCD Modules must be repaired.

Do not stack LCD Modules: 

The LCD Module consists of 

fragile components such as TCPs or Glasses. Stacking the 
LCD Modules can cause undesired defects.

Do not provide strong pressure at connecting: 

Strong 

pressure can transfer the force to the TCP, which is the 
weakest part of the LCD Module. It eventually can make 
the TCP crack or lead to other unexpected defects.

Let the Backlight Wire at the backside of the LCD 
Module:

 If let the Backlight wire in front of the LCD Module, 

the Backlight connector can hurt the surface of the 
polariser.

Never (dis)connect at power “ON”:

 The LCD Module 

consists of CMOS components, which are known as weak 
components against EOS. It can damage the product.

Electro-static discharge can make damage:

Semi-assembled product should be handled with wrist 
strap.

Earth human body when handle the LCD Module.

Please do not touch the interface connector pin.

System Assembler/End User

Keep clean the surface: 

Please wear rubber gloves when you touch the surface 
of the LCD Module screen.

Please use soft and anti-static material with n-Hexane 
as cleaner.

Be careful not to make polariser scratch:

Surface of polariser is soft, so it’s easily scratched.

Please do not touch, press or rub on polariser surface 
with materials over HB hardness.

Be careful with swift temperature and humidity 
changes: 

Swift temperature and or humidity change can 

make dew condensation or ice, which can cause non-
conformance such as malfunctioning.

Keep out of water:

Water on in the LCD Module can cause electrical short 
or corrosion.

Please wipe out or dry water carefully.

Keep the LCD Module free from corrosive gasses: 

Corrosive gas can chemically damage the polariser and 
the circuitry parts and eventually will cause defects.

Keep the suitable temperature and humidity: 

High 

temperatures and high humidity will shorten the lifetime
