1. General Description
The LC550EUN is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive display type which is operating in the normally black mode. It has a 54.64 inch diagonally
measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7Milion colors.
It has been designed to apply the 8-bit 2-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

2. Temperature and relative humidity range are shown in the figure below.
Wet bulb temperature should be Max 39C, and no condensation of water.
3. Gravity mura can be guaranteed below 40C condition.
4. The maximum operating temperatures is based on the test condition that the surface temperature
of display area is less than or equal to 68C with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature of
display area from being over 68. The range of operating temperature may be degraded in case of
improper thermal management in final product design.

1. Electrical characteristics are determined after the unit has been ON and stable for approximately 60
minutes at 252C. The specified current and power consumption are under the typical supply Input voltage
24Vand V
BR (ExtVBR-B : 100%), it is total power consumption.
2. The life time (MTTF) is determined as the time which luminance of the LED is 50% compared to that of initial
value at the typical LED current (ExtVBR-B :100%) on condition of continuous operating in LCM state at
252C.
3. The duration of rush current is about 200ms. This duration is applied to LED on time.
4. Even though inrush current is over the specified value, there is no problem if I

Note: 1. The input of HSYNC & VSYNC signal does not have an effect on normal operation (DE Only Mode).
If you use spread spectrum of EMI, add some additional clock to minimum value for clock margin.
2. The performance of the electro-optical characteristics may be influenced by variance of the vertical
refresh rate and the horizontal frequency
Timing should be set based on clock frequency.

Note : 1. Contrast Ratio(CR) is defined mathematically as :
www.panelook.com
LC550EUN
Product Specification
Contrast Ratio =
Surface Luminance with all white pixels
Surface Luminance with all black pixels
It is measured at center 1-point.
2. Surface luminance are determined after the unit has been ON and 1 Hour after lighting the
backlight in a dark environment at 252C. Surface luminance is the luminance value at center
1-point across the LCD surface 50cm from the surface with all pixels displaying white.
For more information see the FIG. 2.

9. Precautions
Please pay attention to the followings when you use this TFT LCD module.
9-1. Mounting Precautions
(1) You must mount a module using specified mounting holes (Details refer to the drawings).
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to
the module. And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.
(3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to the resist external force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break
by electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB
pencil lead. And please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental
to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like
chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives
used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause
chemical damage to the polarizer
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient strength.
www.panelook.com
LC550EUN
Product Specification
9-2. Operating Precautions
(1) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(2) Brightness depends on the temperature. (In lower temperature, it becomes lower.)
And in lower temperature, response time(required time that brightness is stable after turned on)
becomes longer
(3) Be careful for condensation at sudden temperature change.Condensation makes damage to polarizer or
electrical contacted parts. And after fading condensation, smear or spot will occur.
(4) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(5) 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 minimized the
interference.
(6) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM cant be operated
its full characteristics perfectly.
(7) A screw which is fastened up the steels should be a machine screw.
(if not, it can causes conductive particles and deal LCM a fatal blow)
(8) Please do not set LCD on its edge.
(9) The conductive material and signal cables are kept away from LED driver inductor to prevent abnormal
display, sound noise and temperature rising.

9-3. Electrostatic Discharge Control
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that
treatment persons are connected to ground through wrist band etc. And dont touch interface pin directly.
9-4. Precautions for Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.
9-5. Storage
When storing modules as spares for a long time, the following precautions are necessary.
www.panelook.com
LC550EUN
Product Specification
(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature
between 5C and 35C at normal humidity.
(2) The polarizer surface should not come in contact with any other object.
It is recommended that they be stored in the container in which they were shipped.
(3) Storage condition is guaranteed under packing conditions.
(4) The phase transition of Liquid Crystal in the condition of the low or high storage temperature will be
recovered when the LCD module returns to the normal condition.
9-6. Operating condition guide
(1) The LCD product should be operated under normal conditions. Normal condition is defined as below;
- Temperature : 5 ~ 40 , normal humidity
- Display pattern : continually changing pattern (Not stationary)
(2) If the product will be used in extreme conditions such as high temperature, display patterns or operation
time etc..,
It is strongly recommended to contact LGD for Qualification 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. The LCD product should be applied by global standard
environment. (refer ETSI EN 300, IEC 60721)
