5.4 Power ON/OFF Sequence
Samsung Secret
To prevent a latch-up or DC operation of the LCD Module, the power on/off
sequence should be as the diagram below.
Power supply
Vdd
1ms<T1≤10ms
1ms<T2≤50ms
0<T3≤50ms
1000ms≤T4
1000ms≤T5
100ms≤T6
(Recommend Value)
BLU
T1 : VDDrising time from 10% to 90%
T2 : The time from V
to valid data at power ON.
DD
T3 : The time from valid data off to VDDoff at power Off.
T4 : VDDoff time for Windows restart
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 LED 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.
In Case T5 is less than 1000msec and T6 is less than 100msec,
garbage display can be seen. (It is not related to electrical function issue, just for
recommendation to prevent garbage display )

9. General Precautions
Samsung Secret
9.1 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 them.
(b) Module 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 LED 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.
(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 do 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 ESD (Electro-Static 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 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
handling a module
(o) Pins of Interface connector should not be touched directly with bare hands.

The storage room should provide good ventilation and

Be cautious of a build up of condensation.
Avoid other hazardous environment while storing goods.
range, we recommend you leave them at a temperature of 20
and a humidity of 50% for 24 hours.
(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 Converter power supply should
be connected directly with a minimized length. A longer cable between
the back light and the Converter may cause lower luminance of lamp(LED) and
may require higher startup voltage(Vs).

9.4 Operation Condition Guide
) The LCD product should be operated under normal conditions.
(a
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.
9.5 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,
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.
(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.
(g) Be cautious for detergents or water not to be permeated into the gap
between the module and the panel when placing the module upside down.
