Description
LTA550HQ22 is a color active matrix liquid crystal display (LCD) that uses amorphous silicon
TFT(Thin Film Transistor) as switching components. This model is composed of a TFT LCD panel,
a driver circuit and a back light unit. The resolution of a 55.0“ is 1920 x 1080 and this model can
display up to 16.7 Million colors with wide viewing angle of 89¶ or higher in all directions. This
panel is intended to support applications to provide a excellent performance for Flat Panel Display
such as Home-alone Multimedia TFT-LCD TV and High Definition TV

10. General Precautions
Samsung Secret
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 converter 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 damageto 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 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 ofcontact with hands, legs or clothes, it must
be washed away with soap thoroughly.
(i) Protect the modulefromElectrostatic 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 converter & 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 I/F connector should not be touched directly with bare hands.

10.3 Operation
(a) Do not connect or disconnect the Module in the "Power On" condition.
(b) Power supplyshould 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 LED package and
may require higher startup voltage(Vs).

10.4 Operation Condition Guide
(a
) The LCD product should be operated under normal conditions.
(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 reliabilityand
function may not be guaranteed. Extreme conditions are commonlyfound at
Airports, Transit Stations, Banks, Stock market, and Controlling systems.
www.panelook.com
Samsung Secret
10.5 Others
(a) Ultra-violet ray filter is necessary foroutdoor operation.
(b) Avoid condensation of water. It may result in improper operation or disconnection
of electrode.
(c) Do not exceed the absolutemaximum rating value. ( supply voltage variation,
input voltage variation, variation in part contents and environmental temperature,
and so on)
Otherwise the Module maybe damaged.
(d) If the Module keeps displaying the same pattern for a long period of time,
the imagemay 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.
