*3) No condensation.
[Note 2] The maximum operating temperature is based on the test condition that the surface temperature of
display area is less than or equal to 50ºC with LCD module alone in a temperature controlled
chamber. Thermal management should be considered in your product design to prevent the surface
temperature of display area from being over 60ºC. The range of operating temperature may degrade
in case of improper thermal management in your product design.
[Note 3] The rating of environment is base on LCD module. Leave LCD cell alone, this environment condition
can’t be guaranteed. Except LCD cell, the customer has to consider the ability of other parts of LCD
module and LCD module process.

sequence.
※
When back light is switched on before panel operation or after a panel operation stop, it may not display
normally. But this phenomenon is not based on change of an incoming signal, and does not give damage
to a liquid crystal display.
※ VCC-dip conditions:
(1) When 3.6V≦VCC(min)<4.5V, td≦10 ms
(2) When VCC <3.6 V, VCC-dip conditions should also follow the VCC-turn-on conditions.

Humidity: 80%RH or less
Reference condition: 20°C to 35°C, 80%RH or less (summer)
5°C to 15°C, 80%RH or less (winter)
The total storage time (40°C, 80%RH): 240h or less
Sunlight: Be sure to shelter a product from the direct sunlight.
Atmosphere: Harmful gas, such as acid and alkali which bites electronic components and/or wires must not be
detected.
Be sure to put cartons on palette or base, don’t put it on floor, and store them with removing from wall. Please
take care of ventilation in storehouse and around cartons, and control changing temperature is within limits of
natural environment.
10. PRECAUTIONS
10.1 ASSEMBLY AND HANDLING PRECAUTIONS
(a) Do not apply rough force such as bending or twisting to the module during assembly.
(b) It is recommended to assemble or to install a module into the user’s system in clean working areas. The
dust and oil may cause electrical short or worsen the polarizer.
(c) Since the LCM consists of TFT and electronic circuits with CMOS-ICs, which are very weak to electrostatic
discharge, person who is handling an LCM should be grounded though adequate methods such as an
anti-static wrist band. Connector pins should not be touched directly with bare hands.
Reference: Process control standard is shown as follow,
item Management standard value and performance standard
1 Anti-static mat(shelf) 1to50 [Mega ohm]
2 Anti-static mat(floor, desk) 1to100 [Mega ohm]
3 Ionizer Attenuate from ±1000V to ±100V within two seconds.
4 Anti-static wrist band 0.8 to 10 [Mega ohm]
5 Anti-static wrist band entry and ground resistance Below 1000 [ohm]
6 Temperature 22 to 26 [ ]℃
7 Humidity 60 to 70 [%]
(d) Do not apply pressure or impulse to the module to prevent the damage of LCD panel and backlight.
(e) Always follow the correct power-on sequence when the LCD module is turned on. This can prevent the
damage and latch-up of the CMOS LSI chips.
(f) Be sure to turn off the power supply when inserting or disconnecting the cable.
(g) Do not disassemble the module.
(h) Front polarizer can easily be damaged, so please pay attention on it.
(i) Using a absorbent cotton or other soft cloth without chemicals for cleaning, because the surface of polarizer
is very soft and easily scratched.
(j) Since long contact with drops of water may cause discoloration or spots, please wipe off them as soon as
possible.
(k) The Panel will be broken or chipped when it is dropped or bumped against a hard substance.

LM185TT1A Specification Version1.2
(l) Applying too much force and stress to PWB and drivers may cause a malfunction electrically and
mechanically.
(m) Please be careful since image retention may occur when a fixed pattern is displayed for a long time.
(n) Moisture can easily penetrate into LCD module and may cause the damage during operation.
(o) High temperature or humidity may deteriorate the performance of LCD module. Please store LCD modules
in the specified storage conditions.
(p) This LCM is corresponded to ROHS.
(q) When any question or issue occurs, it shall be solved by mutual discussion.
10.2 SAFETY PRECAUTIONS
(a) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In case of
contact with hands, skin or clothes, it has to be washed away thoroughly with soap.
(b) After the module’s end of life, it is not harmful in case of normal operation and storage.
