※ About the relation between data input and back light lighting, please base on the above-mentioned input

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.

[Note 3] The inverter unit is driving at the following drive frequency.

Lamp driving frequency : 41kHz

Burst dimmer frequency : 165Hz

There is possibility that the display problem of the backlights such as flicker, blinking, etc by the

interference of the above inverter driving frequency and the LCD driving frequency will occur.

In setting of a LCD driving frequency, we recommend to set for the no interference with the above

frequency to occur.

10. Handling Precautions of the module

a) Be sure to turn off the power supply when inserting or disconnecting the cable.
b) This product is using the parts (inverter, CCFT etc), which generate the high voltage.

Therefore, during operating, please don't touch these parts.

c) Brightness control voltage is switched for “ON” and “OFF”, as shown in Fig.4. Voltage difference generated

by this switching, ΔV

INV, may affect a sound output, etc. when the power supply is shared between the

inverter and its surrounding circuit. So, separate the power supply of the inverter circuit with the one of its

surrounding circuit.

d) Be sure to design the cabinet so that the module can be installed without any extra stress such as warp or

twist.

e) Since the front polarizer is easily damaged, pay attention not to scratch it.
f) Since long contact with water may cause discoloration or spots, wipe off water drop immediately.
g) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth.
h) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with

care.

i) Since CMOS LSI is used in this module, take care of static electricity and take the human earth into

consideration when handling.

j) Please consider to minimize the influence of EMI and the exogenous noise before designing the grounding of

LCD module.

k) The module has some printed circuit boards (PCBs) on the back side, take care to keep them form any stress

or pressure when handling or installing the module; otherwise some of electronic parts on the PCBs may be

damaged.

l) Observe all other precautionary requirements in handling components.
m) When some pressure is added onto the module from rear side constantly, it causes display non-uniformity

issue, functional defect, etc.. So, please avoid such design.

n) When handling LCD modules and assembling them into cabinets, please be noted that long-term storage in

the environment of oxidization or deoxidization gas and the use of such materials as reagent, solvent,
adhesive, resin, etc. which generate these gasses, may cause corrosion and discoloration of the LCD

modules.

o) Connect a module frame to GND.
