Lamp Current is measured at the point before Lamp.
(1) Max Value of the Power Consumption is measured during initial turn-on time* of the backlight.
(2) Max Value of the Power Consumption is measured after 60 min warm-up.
(3) When EX-DIM(Pin 14) is used, DIM(Pin13) has to be open or connected to ground.
(4) EX-PWM Frequency is selected not to interfere the Waterfall & Acoustic Noise.
* Initial turn-on time : From 0sec to 60min after turn-on

(2) Lamp frequency which may produce interference with horizontal synchronous frequency
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) Life time (Hr) is defined as the time when brightness of a lamp unit itself becomes 50% or
www.panelook.com
less than its original value at the condition of Ta = 25·2¶C and I
(4) Designing a system inverter intended to have better display performance, power
efficiency and lamp reliability.
They would help increase the lamp lifetime and reduce leakage current.
a. The measurement should be done at typical lamp current.
b. The asymmetry rate of the inverter waveform should be less than 10%.
c. The distortion rate of the waveform should be ˲2 with ·10% tolerance.
- Inverter output waveform had better be more similar to ideal sine wave.

5.3 Power ON/OFF Sequence
To prevent a latch-up or DC operation of the LCD Module, the power on/off
sequence should be as the diagram below.

DD
off at power Off.
DD
T5 : The time from valid data to B/L enable at power ON.
T6 : The time from valid data off to B/L disable at power Off.
The supply voltage of the external system for the Module input should be the same
as the definition of V
DD
.
Apply the lamp voltage within the LCD operation range. When the back light turns on
before the LCD operation or the LCD turns off before the back light turns off,
the display may momentarily show abnormal screen.
In case of V
= off level,
DD
please keep the level of input signals low or keep a high impedance.
T4 should be measured after the Module has been fully discharged between power off
and on period.
Interface signal should not be kept at high impedance when the power is on.

10. General Precautions
10.1 Handling
(a) When the Module is assembled, it should be attached to the system firmly
using all mounting holes. Be careful not to twist and bend the Module.
(b) Because the inverter use high voltage, it should be disconnected from power
before it is assembled or disassembled.
(c) Refrain from strong mechanical shock and / or any force to the Module.
In addition to damage, this may cause improper operation or damage to the Module
and CCFL back light.
(d) Note that polarizers are very fragile and could be damage easily.
Do not press or scratch the surface harder than a HB pencil lead.
www.panelook.com
(e) Wipe off water droplets or oil immediately. If you leave the droplets for a long
time, staining or discoloration may occur.
(f) If the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth.
(g) Desirable cleaners are water, IPA(Isopropyl Alcohol) or Hexane.
Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid
or Methyl chloride. It might permanent damage to the polarizer due to chemical
reaction.
(h) 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 with soap thoroughly.
(i) Protect the module from Electrostatic discharge. Otherwise the ASIC IC or
Semiconductor would be damaged
.
(j) Use finger-stalls with soft gloves in order to keep display clean during the
incoming inspection and assembly process.
(k) Do not disassemble the Module.
(l) Do not disassemble shield case of inverter & LVDS board.
(m) Do not connect N.C pins. (Samsung internal use only)
(n) Protection film for polarizer on the Module should be slowly peeled off just before use
so that the electrostatic charge can be minimized. Must put on antistatic glove while
handle a module
(o) Pins of I/F connector should not be touched directly with bare hands.

10.2 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 from 0 to 35
and relative humidity of less than 70%.
(b) Do not store the TFT-LCD Module in direct sunlight.
(c) The Module should be stored in a dark place. It is prohibited to apply sunlight or
fluorescent light in storing.
10
.3 Operation
www.panelook.com
(a) Do not connect or disconnect the Module in the "Power On" condition.
(b) Power supply should always be turned on/off by the "Power on/off sequence"
(c) Module has high frequency circuits. Sufficient suppression to the electromagnetic
interference should be done by system manufacturers. Grounding and shielding methods
may be important to minimize the interference.
(d) The cable between the back light connector and its inverter power supply should
be connected directly with a minimized length. A longer cable between
the back light and the inverter may cause lower luminance of lamp(CCFT) and
may require higher startup voltage(Vs).
10.4 Operation Condition Guide
(a) The LCD product should be operated under normal conditions.
Normal condition is defined as below;
- Temperature : 20·15
- Humidity : 55·20%
- Display pattern : continually changing pattern (Not stationary)
(b) If the product will be used in extreme conditions such as high temperature,
humidity, display patterns or operation time etc.., It is strongly recommended
to contact SEC for Application engineering advice. Otherwise, its reliability and
function may not be guaranteed. Extreme conditions are commonly found at
Airports, Transit Stations, Banks, Stock market, and Controlling systems.

10.5 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. ( supply voltage variation,
input voltage variation, variation in part contents and environmental temperature,
and so on)
Otherwise the Module may be damaged.
(d) If the Module keeps displaying the same pattern for a long period of time,
the image may be "sticked" to the screen.
To avoid image sticking, it is recommended to use a screen saver.
www.panelook.com
(e) This Module has its circuitry PCB's on the rear side and should be handled
carefully in order not to be stressed.
(f) Please contact SEC in advance when you display the same pattern for a long time.
