Description
LTI550HF02 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
panel, a driver circuit and a bac
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 Display terminals for AV application
products and Digital Information Display (DID).

2. Application information for DID (Digital Information Display)
A long-term display like DID application may cause uneven display including image retention.
o optimize module's
me and function, several operating usages are required.
1. Normal operating condition
- Temperature: 20 · 15
- Humidity: 55 · 20 %
- Display pattern: moving picture or regular switchover display
Note) Long-term static information image may cause uneven display.
2. Operating usages under abnormal operating condition. Note (1)
a. Ambient condition
- Well-ventilated place is recommended to set up DID system.
b. Power off and screen saver
- Periodical power-off or screen saver is needed after long-term static display. Note (2)
3. Operating usages to protect uneven display due to long-term static information display
a. Suitable o
erating time for P-DID : under 20 hours a day.
b. Periodical display contents change from static image to moving picture.
- Liquid crystal refresh time is required.
c. Periodical background color and character (image) color change
- Use different colors for background and character (image), respectively.
- Change colors periodically.
d. Avoid combination of background and character with large different luminance.
Note (2) Moving picture or black pattern is strongly recommended for screen saver.
.
4. Lifetime in this spec is guaranteed only when DID is used under right operating usages.

10. General Precautions
Samsung Confidential
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 CCFT backlight.
(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.
.
(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.
it
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 static, or the CMOS Gate Array IC 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 adjust the variable resistor located on the Module.
(m) Protection film for polarizer on the Module should be slowly peeled off just before
use so that the electrostatic charge can be minimized.
(n) 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
Samsung Confidential
(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 backlight connector and its inverter power supply should
be connected directly with a minimized length. A longer cable between the backlight
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.

(a) Ultra-violet ray filter is necessary for outdoor operation.
(b) Module should be turned clockwise (regular front view perspective) when used in
(c) Avoid condensation of water. It may result in improper operation or disconnection
of electrode.
(d) Do not exceed the absolute maximum rating value. (supply voltage variation,
input voltage variation, variation in part contents and environmental temperature,
Otherwise the Module may be damaged.
(e) 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.
'
in order not to be stressed.
(g) Please contact SEC in advance when you display the same pattern for a long time.
