3.2 BACK-LIGHT UNIT
The backlight system is an edge - lighting type with single CCFL( Cold Cathode Fluorescent Lamp ).
The characteristics of single lamp are shown in the following tables.

Startup Voltage VS - - Vrms (5)

Note) The waveform of the inverter output voltage must be area symmetric and the design of the inverter
must have specifications for the modularized lamp.
The performance of the backlight, for example life time or brightness, is much influenced by the
characteristics of the DC-AC inverter for the lamp. So all the parameters of an inverter should be carefully
designed so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure that a poor lighting caused by the mismatch of
the backlight and the inverter(miss lighting, flicker, etc.)never occur. When you confirm it, the module
should be operated in the same condition as it is installed in your instrument.
Note (1) Lamp current is measured with a high frequency current meter as shown below.
HOT : Sky Blue

LCD COLD : WHITE
3 INVERTER
MODULE A
No 3 Pin is VLOW. SEMCO,SIC-130
Switching Frequency : 40 ~ 60 KHz
(2) Lamp frequency may produce interference with horizontal synchronous frequency and this
may cause line flow on the display. Therefore lamp frequency should be detached from the
horizontal synchronous frequency and its harmonics as far as possible in order to avoid interference.
(3) refer to IL ¡¿ VL to calculate.
(4) Life time (Hr) of a lamp can be is defined as the time in which it continues to operate under the
condition Ta = 25¡É and IL = 4.0 mArms until one of the following event occurs.
1. When the brightness becomes 50% or lower than it's original.
2. When the Effective ignition length becomes 80% or lower than it's original value.
(Effective ignition length is defined as an area that has less than 70% brightness compared to
the brightness in the center point.)
(5) The voltage above this value should be applied to the lamp for more than 1 second to startup
Otherwise the lamp may not be turned on.

NOTE.
(1) The supply voltage of the external system for the module input should be the same
as the definition of VDD.
(2) Apply the lamp voltage within the LCD operation range. When the backlight turns on
before the LCD operation or the LCD turns off before the backlight turns off, the
display may momentarily become white.
(3) In case of VDD = off level, please keep the level of input signals on the low or keep
a high impedance.
(4) T4 should be measured after the module has been fully discharged between power
off and on period.
(5) Interface signal shall not be kept at high impedance when the power is on.

8. GENERAL PRECAUTIONS
1. Handling
(a) When the module is assembled, It should be attached to the system firmly
using every mounting holes. Be careful not to twist and bend the modules.
(b) Refrain from strong mechanical shock and / or any force to the module. In addition to
damage, this may improper operation or damage to the module and CCFT backlight.
(c) Note that polarizers are very fragile and could be easily damaged. Do not press or scratch
the surface harder than a HB pencil lead.
(d) Wipe off water droplets or oil immediately. If you leave the droplets for a long time,
Staining and discoloration may occur.
(e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth.
(f) The desirable cleaners are water, IPA(Isoprophyl Alcohol) or Hexane.
Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl
chloride. It might permanently damage the polarizer due to chemical reaction.
(g) 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, legs or clothes, it must be washed away thoroughly
with soap.
(h) Protect the module from static , it may cause damage to the C-MOS Gate Array IC.
(i) Use fingerstalls with soft gloves in order to keep display clean during the incoming
inspection and assembly process.
(j) Do not disassemble the module.
(k) Do not pull or fold the lamp wire.
(l) Do not adjust the variable resistor which is located on the back side.
(m) The cable for lamp(CCFT) shall not be pull or held.
(n) Protection film for polarizer on the module shall be slowly feeled off just before use so
that the electrostatic charge can be minimized.
(o) Pins of I/F connector shall not be touched directly with bare hands.
Doc.No. LT133X1-106 Rev.No 002-S-971117 Page 24 / 25
2. STORAGE
(a) Do not leave the module in high temperature, and high humidity for a long time.
It is highly recommended to store the module with temperature is from 0 to 35 ¡É and
Relative humidity of less than 70%.
(b) Do not store the TFT-LCD module in direct sunlight.
(c) The module shall be stored in a dark place. It is prohibited to apply sunlight or fluorescent
light during the store.
3. OPERATION
(a) Do not connect,disconnect the module in the " Power On" condition.
(b) Power supply should always be turned on/off by following item 6.3
" Power on/off sequence ".
(c) Module has high frequency circuits. Sufficient suppression to the electromagnetic
interference shall be done by system manufacturers. Grounding and shielding methods
may be important to minimize the interference.
(d) The cable between the backlight connector and its inverter power supply shall be a
minimized length and be connected directly . The longer cable between the backlight
and the inverter may cause lower luminance of lamp(CCFT) and may require higher
startup voltage(Vs).
4. OTHERS
(a) Ultra-violet ray filter is necessary for outdoor operation.
(b) Avoid condensation of water. It may result in improper operation or disconnection
of electrode.
(c) Do not exceed the absolute maximum rating value. ( the supply voltage variation, input
voltage variation, variation in part contents and environmental temperature, so on)
Otherwise the module may be damaged.
(d) If the module Displays the same pattern continuously for a long period of time,it can be
the situation when the image "sticks" to the screen.
(e) This module has its circuitry PCB's on the rear side and should be handled carefully in
order not to be stressed.
