Caution
Use the inverter providing symmetrical sine-wave in positive/negative polarity with no spike.
A shield(module’s metal shield) should be connected to GND of inverter circuit.

11. Shipping requirements
a) Number of layers of cartons in pile : 12 layers max.
b) Maximum number of product contained: 20 units per 1 carton.
c) Carton size : 442mm(W) 390mm(H) 170mm(D)
d) Total mass ( for 20 units ) : Approximately 5.5
e) Carton stock environment :
Temperature
0 to 40
Humidity
60%RH or less
Atmosphere
Harmful gases such as acid and alkali which corrode electric
components and wires must not be detected.
Storage period
Approximately 3 months
Opening of package To prevent TFT-LCD module from being damaged by electrostatic,
adjust the humidity to 50%RH or higher and provide
an appropriate measure for electrostatic earthing before
opening the package.
12. Others
a) Adjusting volumes have been set optimally before shipment. Therefore, do not change any
adjusted values. If adjusted values are changed, the specifications described here may not be
satisfied.
b) Disassembled the module, it may cause malfunction.
c) Be careful since image retention may occur when a fixed pattern is displayed for a long time.
d) Input/Output connector for TFT-LCD panel driving part
Used connector :
1) Fit FPC : Refer to the following figure
2) Keeping power of terminal : 0.9N/pin or more
[ Every terminal is pulled out 25 3mm/minute ]
3) Endurance of insert/pull out : Less than double of the initial resistance value
[ The electrical resistance value of the contact changed by the repeated insertion/pulling
out by 20 times to and from the matching FPC ]
No. Parameter
Material
1 Base material Polyimide or the equivalent [ 25um thickness ]
2 Copper leaf
Copper leaf [ 35um thickness ] gold leaf[ 2um or more thickness ]
3 Coverlay
Polyimide or the equivalent
4 Reinforced sheet Polyester, polyimide or the equivalent [ 188um thickness ]
Fit FPC for Input/Output connector : 0.5mm pitch
